1. Fix error recovery mechanism during transmission error
handling (enable transmission at the end).
2. Fix compilation / operation with CONFIG_SAMV7_EMAC_PREALLOCATE=y
3. Enable fully configured address space for transmission queues
to allow sending packets with length more than 976 bytes. With
partially configured address space the AHB error is generated
during transmission of long packets.

With faster data transfer rates, it was seen that the read
requests occasionally were issued while the USB RX operation
was actually in progress. This patch makes sure the system
doesn't accidentally read the RX fifo while it's being filled
up, but rather, checks for the RXCSRL_REG_EPN_RX_PKT_RDY_MASK
flag. This flag indicates the packet is ready to be read.

cache_dbus_mmu_set and cache_ibus_mmu_set return positive values in case
of errors, so DEBUVERIFY could never detect them since this macro checks
for negative values.
Besides, the successful execution of those functions is mandatory for
the reliable operation under Protected Mode, so the verification is
always performed, even when DEBUG is not enabled.

For each UART, if Kconfig enables RTS/CTS (e.g.,

configure the corresponding GPIO(s).
* arch/arm/src/tiva/common/tiva_serial.c:
(struct up_dev_s):
If CONFIG_SERIAL_IFLOWCONTROL, add a bool field 'iflow'. If
CONFIG_SERIAL_OFLOWCONTROL, add a bool field 'oflow'. This is
inspired by the implementation for kinetis.
(g_uart0priv, g_uart1priv, g_uart2priv, g_uart3priv, g_uart4priv,

If Kconfig enables RTS/CTS for a UART (e.g.,
CONFIG_UART0_IFLOWCONTROL thru CONFIG_UART7_OFLOWCONTROL), set
the corresponding iflow and/or oflow flag(s).
(up_setup):
Check the above-mentioned iflow and oflow flags and set or unset

the feature.

Starting the rptun with the autostart flag set will cause significant
delays at the boot, as it will wait for the master to be up. U-boot/linux
combination may take more than 10 seconds to boot to the point where the
rpmsg bus is initialized.
For now, the user needs to initialize the rptun separately, for example,
by issuing the following command:
rptun start /dev/rptun/mpfs-ihc
This command will also block if started before the rpmsg bus master is up.

When using HSE to clock RTC NuttX internal time is gaining 5.5 second per
minute. Problem was NuttX using 7182 for one of the RTC division factors,
it should have been 7812. The incorrect factors used are 7182 and 0xff.
These are used in 3-4 places within Nuttx and other places as 7812 and 0xff.
However, the STMicro app note AN4759 suggests using 7999 and 124, which is
what I've used.
Explanation: These 2 factors are used to divide the HSE clock (which at this
point is 1 MHz) to 1 Hz for the RTC hardware.
To test the 2 factors, add 1 to both numbers and multiply them together.
The result needs to be as close as possible to 1 MHz.
The suggested values of 7999 and 124 => 8000*125 = 1,000,000, the prime
factors. So, the best fix for Nuttx would be these values.

The old implementation needed a contiguous memory block for user
ROM/RAM. This is because there was only 1 L3 page table which can only
map a contiguous memory area.
Also, remove the PMP configuration which just complicates things,
rely on the MMU mappings instead.
Update PLL configuration parameters to match the values provided
by the vendor.
Also remove extra call to mpfs_pll_config() as it's already called
at mpfs_clockconfig().

This patch adds new chip family, stm32wl5x. This is bare minimum
implementation of said chip. I've tested this by running nsh.
There are only two chips in this family, stm32wl55 and stm32wl54.
The only difference between them is that stm32wl55 has LORA.
stm32wl5 is dual CPU (not core!). Right now only CPU1 is implemented.
CPU0 has access to radio hardware (while CPU1 does not). Chip is
designed so that CPU0 handles radio traffic while CPU1 does the
heavy lifting with data - there is communication pipe between two
CPUs.
I plan to use nuttx on CPU1 and LORA from stm32cube on CPU0 so I
don't have implementing CPU0 right now - once we have working LORA
in nuttx this may change.
Peripherals (except for radio) are shared so it's best to focus on
CPU1 to initialize all peripherals so that CPU0 can only use them
later. There is no real benefit to implement CPU0 if we don't have
working LORA/radio support in nuttx.
In time I will be implementing more and more things from this chip.
Right now I would like this minimal implementation to be merged in
case someone wants to work on this chip as well.

Change pin initialization timing for camera from board power on to camera device
power on for the following purposes.
- avoid unnecessary power consumption
- Make the corresponding pins available for other uses when camera is not in use
RF and system timer interrupt are used for ble.
tlsr82_flash.c:
1. BLE will loss packets during flash operation beacause the interrupt
is disabled and the operation take too long (especially erasing,
about 100ms), so allow RF and system timer interrupt during flash
operation;
2. Add sched_lock()/sched_unlock() to avoid the task switch in ble and
system timer interrupt;
flash_boot_ble.ld:
3. Because of 1, the code executes in RF and system timer interrupt
must be in ram to avoid bus error. The sem_post() will be called and
const variable g_tasklisttable will be accessed in RF and system
timer interrupt handler;
4. To improve the performance, copy some frequently called function to
ram as well, such as: sem_take(), sched_lock(), sched_unlock(),
some lib functions, some zephyr ble functions and some tinycrypt
functions;
5. The RF and system timer interrupt handler will call some libgcc
functions, so copy all the libgcc functions to ram exclude _divdi3.o,
_udivdi3.o and _umoddi3.o;
tlsr82_serial.c
6. Make up_putc() be thread safe, add enter/leave_critical_section() in
function uart_send_byte();
tc32_doirq.c
7. Increase the RF and system timer interrupt response priority;

Linux kernel uses M-mode trap for handling Inter-Hart Communication (IHC).
This patch provides all the required functionalities for this purpose.
Previously, HSS bootloader was required. Now, NuttX is run as the
bootloader providing OpenSBI vendor extensions instead. This setup has
been tested on the following configuration:
- Hart 0 has NuttX in bootloader mode with OpenSBI
- Hart 1 unused
- Hart 2 has NuttX configured at 0xa2000000
- Hart 3 has U-boot / Linux kernel (at 0x80200000)
- Hart 4 has U-boot / Linux kernel (at 0x80200000)
Upon startup, NuttX on hart 0 will initialize SD-card driver, loads
the hart 2 NuttX from the SD-card and loads the U-boot to 0x80200000.
Also the nuttx.sbi -binary is loaded from SD-card into address 0x80000000,
which is also marked as reserved area in the Linux kernel device tree (for
the chuck 0x80000000 - 0x80200000).
Hart 2 NuttX waits until Linux kernel (IHC master) is started. After the
initial handshake, RPMsg / virtIO bus along with the IHC may be used for
proper AMP mode.
