When any error was detected the buffers descriptors were
blindly initialized. This caused the TX of the MAC to
be in a bad state. The correct thing to do, we disable
the MAC, init the bufffers and re-eanable the MAC.
The interrupts were being throlled at the NVIC. This been
cleaned up.

This fixes the following 3 issues:
1. Wait for send to complete in exchange
Before shutting down the SPI, we have to wait for send to complete; not only
DMA, since DMA just puts data to the SPI fifo. It is not yet out of SPI.
When doing exchange with both send & receive this is not an issue because when
receive dma has completed, it is certain that also the send is.
This can be accomplished by completing the transfer in SPI TXC interrupt
instead of DMA callback.
2. Fix TXDMAEN and RXDMAEN placement
According to the spec, the RXDMAEN must be enabled before
enabling DMA requests for Tx and Rx in DMA registers, and TXDMAEN
after that.
Cleaner place to do this is in spi_dmarxstart and spi_dmatxstart, where
also the dma requests are enabled. This also handles properly the
simplex modes.
3. Remove bus signal glitches when shutting off SPI block
Use AFCNTR to avoid glitches in SPI lines while turning SPI block
on/off during calls to exchange.

574b25 broke the internal DMA buffers usage that solved
the following problem: The DMA capable interface does
not know the buffers extent. It calulates it from size.
The user may need to transfer less than a cachline bytes,
but STILL have a DMA cabable buffer. The user is therefore
foreced to transfer more data then needed to "trick" the
DMA cabable function. This is a wast of bus bandwith and
may not work will all devices. The internal buffer, solve
this issue.

For SDMMC1, IDMA cannot access SRAM123 or SRAM4. Refer to ST AN5200 for
details. This patch makes stm32_dmapreflight check the buffer address and
return an error when the buffer is located in a invalid address space.
This does not fix the hardware limitation but at least makes it visible.
This simplifies the sdmmc driver when the IDMA is in use. There is no need to mix
IDMA and interrupt based transfers; instead, when making unaligned data tranfers,
just make IDMA into an internal aligned buffer and then copy the data.

It should not be an error to clean cache beyond the dma source buffer
boundaries. It would just prematurely push some unrelated data from
cache to memory.
The only case where it would corrupt memory is that there is a dma
destination buffer overlapping the same cache line with the source
buffer. But this can't happen, because a destination buffer must always
be cache-line aligned when using write-back cache.
This patch enables doing dma tx-only transfer from unaligned source
buffer when using write-back cache.

Remove support for the Codesourcery, Atollic, DevKitArm, Raisonance, and CodeRed toolchains. Not only are these tools old and no longer used but they are all equivalent to standard ARM EABI toolchains. Retaining specific support has no effect (they are still supported, but now just as generic EABI toolchains).
First, configure the dmacfg in spi_dmarxsetup and spi_dmatxsetup. Then,
check for dmacapable, and only after that set up the dma.
This way the dmacapable actually works, and we don't need to initialize
the dmacfg structures twice.

When starting dma transfer, the dcache for the TX buffer should be cleaned.
"flush" performs also invalidate, which is unnecessary. The TX buffer
can be unaligned to the cahche line in some(most) cases, whereas RX buffer
can never be.
The cache for the receive buffer can be dirty and valid before call to exchange.
Thus another memory access (hitting the same cache line) may corrupt receive data
while waiting for transfer to complete. So the receive buffer should be
invalidated before the transfer

All complaints fixed except for those that were not possible to fix:
- Used of Mixed case identifier in ESP32 files. These are references to Expressif ROM functions which are outside of the scope of NuttX.
- Remove per-thread errno from the TCB structure (pterrno)
- Remove get_errno() and set_errno() as functions. The macros are still available as stubs and will be needed in the future if we need to access the errno from a different address environment (KERNEL mode).
- Add errno value to the tls_info_s structure definitions
- Move sched/errno to libs/libc/errno. Replace old TCB access to the errno with TLS access to the errno.
Move the logic to get TLS information from an inline function to a normal function. For the unaligned case, it is probably too large to be inlined.
Also fixes some minor things from review of previous commits.

As pointed out by Şükrü Bahadır Arslan in PR765, function calls
inside DEBUGASSERT() will not be executed if DEBUGASSERT is
disabled. Following that PR, I searched for other instances of
similar errors and found four. As there are many thousands of
DEBUGASSERT in the code, this is *not* an exhaustive fix.
arch/arm/src/tms570/tms570_boot.c:
* In function arm_boot(), call tms570_memtest_complete()
outside of the DEBUGASSERT(). Otherwise, if DEBUGASSERT is
disabled, we will never rendezvous with completion of the
test. (Two instances of this fix.)
arch/arm/src/tms570/tms570_clockconfig.c:
* In function tms570_clockconfig(), call
tms570_efc_selftest_complete() outside of the DEBUGASSERT()
for the same reason as above.
boards/arm/sam34/sam4s-xplained-pro/src/sam_boot.c:
* In function board_late_initialize(), call
sam_watchdog_initialize() outside of the DEBUGASSERT() for
the same reason as above.
Run all files modified by PR 766 through nxstyle and fix any resulting complaints.
NOTE: Numerous "Mixed case identifier" errors in arch/arm/src/cxd56xx/cxd56_gnss.c were not fixed because this problem is of much larger scope than this file.
This commit resolves issue #620:
Remove CONFIG_CAN_PASS_STRUCTS #620
The configuration option CONFIG_CAN_PASS_STRUCTS was added many years ago to support an old version of the SDCC compiler. That compiler is currently used only with the Z80 and Z180 targets. The limitation of that old compiler was that it could not pass structures or unions as either inputs or outputs. For example:
#ifdef CONFIG_CAN_PASS_STRUCTS
struct mallinfo mallinfo(void);
#else
int mallinfo(FAR struct mallinfo *info);
#endif
And even leads to violation of a few POSIX interfaces like:
#ifdef CONFIG_CAN_PASS_STRUCTS
int sigqueue(int pid, int signo, union sigval value);
#else
int sigqueue(int pid, int signo, FAR void *sival_ptr);
#endif
This breaks the 1st INVIOLABLES rule:
Strict POSIX compliance
-----------------------
o Strict conformance to the portable standard OS interface as defined at
OpenGroup.org.
o A deeply embedded system requires some special support. Special
support must be minimized.
o The portable interface must never be compromised only for the sake of
expediency.
o Expediency or even improved performance are not justifications for
violation of the strict POSIX interface
Also, it appears that the current SDCC compilers have resolve this issue and so, perhaps, this is no longer a problem: z88dk/z88dk#1132
NOTE: This commit cannot pass the PR checks because it depends on matching changes to the apps/ directory.
So call 'make EXTRAFLAGS=-Wno-cpp' could suppress the warnings with pre-processor
directive #warning in GCC.

This commit fixes some long single line comments. This effort was primarily intended to verify the change to tools/nxstyle of PR #743 further. This took the files changed with 1501d284c3 and ran them through nxstyle again. The files in the commit previously passed the old nxstyle test with no complaints. The current nxstyle, on the other hand, reported 49 long single line comments. Each of those were verified and the file was updated. The nxstyle change appears completely reliable.
Resolution of Issue 619 will require multiple steps, this part of the first step in that resolution: Every call to nxsem_wait_uninterruptible() must handle the return value from nxsem_wait_uninterruptible properly. This commit is for all remaining drivers in the LC823450 architectures.

NOTES:
- arch/arm/src/sama5/sam_can.c: Generates several "Mixed case identifier" complaints because definitions provided by header files that are not part of the change.
- arch/arm/src/sama5/sam_pmecc.c: Has two cases of "Mixed case identifies" result within commented out code. There are references to undefined types that might be provided by Atmel logic (Pmecc and Pmerrloc) if it were ever integrated.

In the sam_usb.c file for these two architectures, the USB suspend() operation is implemented, but never called from anywhere. This logic might be valuable in the future for for now it just causes errors due to the unused static function.
This commit just disables the suspend() logic with #if 0 to eliminate the error. The suspend logic is, however, still preserved in case it is needed in the future.

The SDIO interface structure includes fields with names like recvR1 and others. These cause "Mixed case identifier" errors from nxstyle in all places they are uses.

Alternatively we can use the ARCH_HAVE_MODULE_TEXT mechanism.
But it's considered overkill for the sim, which is mainly

c/vpnkit-tap-vsockd/tap-vsockd.c
With minimum changes to make it build.
* stm32h7_qspi: Board.h now may define the BOARD_QSPI_CLK macro to select one of
RCC_D1CCIPR_QSPISEL_{HCLK,PLL1,PLL2,PER} clocks to use with QUADSPI peripherial.
Defaults to HCLK for backward compatibility.
New macros in qspi.h: QSPICMD_IDUAL and QSPICMD_IQUAD for selecting the bit
width for instruction code (1,2 or 4 bits) of a qspi_cmdinfo_s, and
QSPIMEM_IDUAL and QSPIMEM_IQUAD for selecting the bit width of a qspi_meminfo_s.
* NX style fixes
Necessary for dlfcn etc on ESP32, which has separate memory regions
for instruction and data.
known issues/todo
* consider something similar to dual heaps for PROTOECTED
* consider to adapt binfmt as well
The remaining errors:
Operator/assignment must be preceded with whitespace
I didn't fix them because they are in assembly code, which
nxstyle doesn't understand.
The remaining errors:
Mixed case identifier found
I didn't fix them because they were on ROM symbols,
which are not supposed to obey NuttX's coding style.
Unfortunately nxstyle is still not happy because it doesn't
like the following construct. I'm not sure what to do here.
struct
{
const char *pathname;
long mode;
size_t len;
} open =
{
.pathname = pathname,
.mode = host_flags_to_mode(flags),
.len = strlen(pathname),
};
I skipped the following files because they were not simple.
I'll create separate PRs.
arch/xtensa/src/esp32/esp32_cpustart.c
arch/xtensa/src/common/xtensa_abi.h
boards/xtensa/esp32/esp32-core/include/board.h
Also, I skipped the following files and directories because
they looked too huge and/or foreign.

arch/xtensa/include/esp32/tie-asm.h
arch/xtensa/include/esp32/core-isa.h
arch/xtensa/include/xtensa/core.h
I also fixed a few "is is" style typos when unwrapping long lines.
arch/z80/src/ez80/ez80_timerisr.c: Correct a mismatch between the programmed reload value and the timer input clock frequency.
arch/z80/src/ez80/ez80f92.h: Correct error in timer input clock divider: Bits 2-3, not bits 3-4.
boards/z80/ez80/z20x/src/w25_main.c: Correct an uninitialized return value; private function was not declard static.
* stm32h7: New timer output mode STM32_TIM_CH_OUTTOGGLE.
In this mode timer generates a square waveform on given timer channel.
The maximal waveform freq is timer clock divided by 4 (prescaler 1, period 1 results in 2 clocks '0' and 2 clocks '1').
* stm32_tim.h styling fixes.
arch/z80/src/ez80/ez80f92_init.asm: Timer control register was not being cleared and, as a result, timer interrupts may have been already enabled when the CPU was started by the debugger. This would result in spurious interrupts and Unexpected Interrupt crashes.
arch/z80/src/comming/up_initialize.c: Fix a trivial typo.
While we are at it, change the license headers in all relevant files in the affected directories to the Apache 2.0 license. Run all affected files through nxstyle.
boards/z80/ez80/z20x: Increase RX buffer size to 4Kb, reduce BAUD to 2400 in w25boot configuration
arch/z80/src/ez80/ez80_serial.c: Reduce Rx FIFO trigger level for eZ80F92 to 1 so that will respond more quickly to incoming data.
Also fix the following build warning:

This reverts commit f735584514.
These header changes introduce unacceptable errors:
1. The changes alter the width of the initial block comment. That will cause nxstyle failures on most of the files.
2. The third line of the header is an (optional) short description of content of the the file. This change erroneously removes that line.
Automated header file changes can screw up a lot of files, very quickly.
Commit 797e45d6bf attempted to reduce the frequency of SPI reconfiguration by keeping track of the current frequency and mode settings and changing these settings only when the new settings differ from the old settings.
However, the original commit neglected to save the new frequency setting and, hence, was not effective in what it was trying to do: Every time the SPI setfrequency() method was called, it still looked like a new frequency and the frequency was still reconfigured, even though it hadn't really changed.

arch/z80/src/ez80/ez80_spi.c: Do not configure SPI chip select pin. It is not used by the driver and configuring it just clobbers other usage of that pin. Add some additional debug outputs; correct some exiting debug outputs.
drivers/mtd/w25.c: Add some debug output.
boards/z80/ez80/z20x/src/ez80_w25.c: Correct SPI bus number used in initialization. Only SPI1 is supported.
arch/z80/src/ez80/ez80_timerisr.c: Some initial timer configuration fixes.
The DBGMCU_APB1_FZ bit persists over regular software resets until next POR-reset. It can impact device power consumption and things that persist over resets are a bane for FOTA updates so make it disabled by default.
OpenOCD sets this via DAP when connecting to target so enabling this from Kconfig is only useful for users of some other debug tooling.

Kconfig files. Repartition some functionality. Bootloader support will need to be provided in logic under arch/z80/src/ez80 so the critical configuration selections were moved the Kconfig file there.
arch/z80/src/ez80/ez80_i2c.h: Rename arch/z80/src/ez80/ez80f91_i2c.h. It is sharable by both ez80f91 and ez80f92.
arch/z80/src/ez80/: Add logic to perform an additional level of interrupt redirection. This is necessary because the the interrupt handling is part of the loader FLASH-based logic. In order to share interrupts with the program loaded into RAM by the loader, another layer or redirection is required to get control to the interrupt handlers in the loaded program. See ez809f2_loader.asm and ez80f92_program.asm
boards/z80/ez80/z20x/scripts: Reduce size of the interrupt re-direction buffer from 1Kb to 512b.
Run all .c files modified by PR424 through nxstyle and correct most of the complaints (many long line complaints ignored for now). Update file headers to use Apache 2.0 license.
Not canceling the I2C timeout watch dog immediately after finishing
all I2C transactions in interrupt context can lead to a race condition
due to nxsem_wait(&priv->wait) in lpc17_40_i2c_start() not resuming
execution fast enough (this can be easily triggered if another task /
thread is using a lot of cpu time).
Falling to cancel the watchdog up to time will cause the priv->wait
semaphore to be incremented twice (first by lpc17_40_i2c_stop() then
by lpc17_40_i2c_timeout()), so all I2C transactions after that will
return immediately and priv->msgs will hold pointers to memory it
doesn't own anymore.
Canceling the priv->timeout watch dog in lpc17_40_i2c_stop() prevents
this as it is executed from the I2C interrupt handler.
arch/arm/src/lpc17xx_40xx/lpc17_40_i2c.c: Fix timeout calculation
For each byte received / transmitted, an acknowledge bit is also
transmitted / received, requiring effectively 9 bits for each byte.
The SD boot loader was not satisfactory because 1) the SD slot is on an optional board and, hence, cannot be part of a fundamental solution. And 2) it is too big.
The only storage on borard is the Winbond W25 SPI-bsed FLASH. This commit adds support for a bootload to 1) read code in HEX format from a serial port and write it to the W25 FLASH, or 2) read code in binary form from the W25 FLASH into SRAM and execute the loaded program.
boards/z80/ez80/z20x/configs: Added w25boot configuration
boards/z80/ez80/z20x/src: Add bootloader logic, w25_main.c. Add logic to manage shared SRAM memory map so that the loaded program does not clobber the bootloader memory. Add logic to recover the bootloader memory into the heap after the loaded program as started.
boards/z80/ez80/z20x/scripts: Rework scripts and configuration to support a bootloader and program build. The boolloader cannot use all of SRAM; the program must not clobber the SRAM region used by the bootloader.
