tools/mkdeps.c: Fix '\0' missing in MinGW. Implicit bug. There are 2 cases.
1. Under Linux. The code works as planned: '\n' is always replaced with '\0' due to sprintf fills n-1 bytes and reaches buffer length limit.
2. Under Windows/MinGW. There is memory corruption. Seems like it`s a bug inside MinGW/snprintf. Snprintf fills consecutively "oldbase",' ',"str",'\n', but does not inserts trailing '\0' instead of '\n'. And when next append() occurs, strlen() returns garbage-appended "oldbase".
So the fix just removes '\n' and reserves space for '\0'.

Approved-by: GregoryN <gnutt@nuttx.org>
* Clocks were wrongly configured - way too fast because there is no primary divider on LPC4330
This is fixed by means of changing the definitions in the board.h file. I've edited the one for the lpc4330-xplorer board because I'm actually working with Versiboard and don't want to contribute that config just yet while I've still got the drains up on it.
* The LPC43_SDMMC_DELAY register was not being set
I suspect, in the 'real world', it's possible to get away without setting this, but I've added a register definition, default value and register access macros into arch/arm/src/lpc43xx/chip/lpc43_scu.h and then used them in arch/arm/src/lpc43xx/lpc43_sdmmc.c.
* The LPC43_SDMMC_BLKSIZ and LPC43_SDMMC_BYTECNT registers had the wrong values.
The management have already implemented a rather nice block level interface for the stm32 so I've just re-used that to write to these registers as required. I'm slightly nervous that accessing the configuration registers (SCR being the prime example) which has a much smaller block size may not be being done in the right way but it does seem to work correctly, so let's assume it's all OK until someone tells me otherwise.
These fixes have been tested with DMA-based read/write on a LPC4330. Speed via nsh is pretty low but I'm assuming that's just a buffering/implementation issue for now.

Squashed commit of the following:
fs/spiffs: Fix last compilation issue. Now compiles without error. It is still not quite ready for testing as there is additional code review that must be be performed. It is now marked as EXPERIMENTAL so that it can be brought onto the master branch with little risk.
fs/spiffs: Remove some dead code.
fs/spiffs: Weak start of analysis of spiffs_nucleus.c. Renamed to spiffs_core.c
fs/spiffs: Rename spiffs_nucleus.c to spiffs_core.c
fs/spiffs: Remove spiffs_config.h. All configuration settings are now available in the SPIFFS Kconfig options.
fs/spiffs: Finished review, update, and repartitioning of spiffs_check.c. Added spiffs_check.h.
fs/spiffs: Finished review, update, and repartitioning of spiffs_cache.c. Added spiffs_cache.h.
fs/spiffs: Clean up some defines used in debug output statements.
fs/spiffs: Finished review, update, and repartitioning of spiffs_gc.c. Added spiffs_gc.h.
fs/spiffs: Now that VFS interface is completed, I have begun the long march of repartitioning the remaining functionality, reviewing logic, identifying dead code, and cleaning up loose ends.
fs/spiffs: Initial integration of MTD interface, replacing the SPIFFS native flash interface. Lots of open issues such as the use of pages vs. blocks vs. erase blocks and units of addresses, offsets, and lengths that are passed in function calls. Remove SPIFFS_USE_MAGIC support. That option (which default to OFF anyway), wrote a magic value at the beginning of every sector and support verifiable identification of the file system. It was not being and used and removing it makes life simpler.
fs/spiffs: Remove semaphore lock on the file object structure. Ultimately, the file access must modify the volume and access the volume structue which also has a exclusivity lock. So use of the volume lock alone should be sufficient.
Integrated the SPIFFS rename logic into the NuttX VFS. Removed non-standard application calls or convert them to IOCTL commands. These were converted to IOCTL commands: (1) integrity check, (2) garbage collection, and (3) format flash. These were removed: (1) Integrity check callback. These provided a lot of good information about the state of the file system, but such callbacks are not compatible with a POSIX compliant file system. (2) Index maps. The index maps were a performance improvement feature. The user could provide the memory and request that a region of a a file use that memory for improved lookup performance when accessing parts of the file. The fallback is the less performance lookup by traversing the FLASH memory. (3) Removed the quick garbage collection interface (the code is still used internally). Only the full garbage collection is available to the user application via IOCTL.
configs/sim/spiffs: A simulator configuration to use for testing SPIFFS.
fs/spiffs: Integrate SPIFFS logic into NuttX VFS bind() and unbind() methods.
fs/mount/fs_mount.c: Add SPIFFS to the list of drivers that require MTD vs block drivers.
fs/spiffs: Trivial changes, mostly from analysis of how to integrate the rename() VFS method.
fs/spiffs: Connect NuttX VFS unlink method to the SPIFFS_remove() function. Lots of name-changing.
fs/spiffs: Remove non-standard errno support. Remove bogus SPIFFS_LOCK() and SPIFFS_UNLOCK() macros.
fs/spiffs: Add NuttX VFS implementation for statfs() method. Clean up some of the accumulating compilation problems.
fs/spiffs: Add stat(), truncate() methods. Dummy out unsupport mkdir() and rmdir() methods.
fs/spiffs: Replace some of the custom error numbers with standard error numbers.
fs/spiffs: Hooks read(), write(), fstat(), ioctl(), opendir(), closedir(), rewindif(), and readdir() into the NuttX VFS.
fs/spiffs: Beginning the organization to work with the NuttX VFS. Lots of things are get broken!
fs/spiffs: Add spiffs.c which will be the interface between SPIFFS and NuttX. No very close at present, however.
fs/spiffs: Clean up some compile problems introduced by coding standard changes.
fs/spiffs: A little closer to NuttX coding standard.
fs/spiffs: Ran tools/indent.sh against all files. Closer to NuttX coding standard, but needs a lot more effort to be fully compliant.
fs/spiffs: This commit brings in version 0.3.7 of Peter Anderson's SPIFFS. The initial commit includes the core FS files (with some definitions destributed to their correct header files) and hooks into the build system.
many locations: Change occurences of open() followed by file_detach() to file_open(). Change most non-controversion calls to open() to nx_open().
fs/inode/fs_fileopen.c: Flesh out file_open() with some interim, placeholder logic.
fs/inode/fs_fileopen.c: Add a framework for a file_open() implementation (no real logic in place yet).
fs/vfs/fs_open.c: Add nx_open() which is the same as open() except that it does not create a cancellation point nor does it modify the errno variable.

* Add initial implementation of the DMA
* Add across Kxx family support [WIP]
* Incorporate the DMA into the serial
Add polling to serial
do DMA initialisation at UART startup and fix DMA mux setting.
Fix circular DMA handling in the serial driver.
* Adapt defconfig to enable UART1,4 RXDMA
* [WIP] - refactor this with new CONFIG DMA settings
* kinetis/Kconfig:Bring inline with upstream stucture
1. Use the Serial console configuration from drivers/serial/Kconfig

2. Prefix arch specific featurs as such
UARTx_RXDMA->KINETIS_UARTx_RXDMA
* Kinetis:Serial formatting and clean up
* kinetis:DMA Formating and Cleanup
* kinetis:serial Use cleaner DMA API
* kinetis:Make.defs fix duplicate/errant kinetis_dma.o
* kinetis:serial Fix warning/error on only one uart using DMA
The driver can support no DMA on any UART, DMA on some
UARTs or DMA on all UARTs.
In the case of no DMA we disable the DMA based variables
and logic. In the case of all DMA we disable the non
DMA variables and logic, and in the mixed case both
DMA and non DMA variable and logic are enabled.
* kinetis:dma config fix formatting
* kinetis:chip/dma fix formatting
* kinetis:DMA config assume Unknown
Assume KINETIS_DMA_VERSION_UKN for all SoC not versioned
This is as the code was in nuttx prior to this commit
* kinetis:DMAMUX contain versioning- use HAS pattern define Unknown
The pattern for chip versioning is to define 'HAS' constants.
Define KINETIS_DMAMUX_HAS_MONOTONIC_CHCFG to contain the
version numbers to the include soc header and use that define
in the chip headers.
Define the KINETIS_DMAMUX_VERSION_UKN for the default as prior
this commit addressing was by default monotonic for CHCFG
* freedom-k66f:Disable Serial RXDMA

This makes the user interface a little hostile. People thing of an MTU of 1500 bytes, but the corresponding packet is really 1514 bytes (including the 14 byte Ethernet header). A more friendly solution would configure the MTU (as before), but then derive the packet buffer size by adding the MAC header length. Instead, we define the packet buffer size then derive the MTU.
The MTU is not common currency in networking. On the wire, the only real issue is the MSS which is derived from MTU by subtracting the IP header and TCP header sizes (for the case of TCP). Now it is derived for the PKTSIZE by subtracting the IP header, the TCP header, and the MAC header sizes. So we should be all good and without the recurring 14 byte error in MTU's and MSS's.
Squashed commit of the following:
Trivial update to fix some spacing issues.
net/: Rename several macros containing _MTU to _PKTSIZE.
net/: Rename CONFIG_NET_SLIP_MTU to CONFIG_NET_SLIP_PKTSIZE and similarly for CONFIG_NET_TUN_MTU. These are not the MTU which does not include the size of the link layer header. These are the full size of the packet buffer memory (minus any GUARD bytes).
net/: Rename CONFIG_NET_6LOWPAN_MTU to CONFIG_NET_6LOWPAN_PKTSIZE and similarly for CONFIG_NET_TUN_MTU. These are not the MTU which does not include the size of the link layer header. These are the full size of the packet buffer memory (minus any GUARD bytes).
net/: Rename CONFIG_NET_ETH_MTU to CONFIG_NET_ETH_PKTSIZE. This is not the MTU which does not include the size of the link layer header. This is the full size of the packet buffer memory (minus any GUARD bytes).
net/: Rename the file d_mtu in the network driver structure to d_pktsize. That value saved there is not the MTU. The packetsize is the memory large enough to hold the maximum packet PLUS the size of the link layer header. The MTU does not include the link layer header.

lpc17: Removed duplicate configuration variable definitions from Kconfig: CONFIG_USBHOST_BULK_DISABLE, CONFIG_USBHOST_INT_DISABLE, and USBHOST_ISOC_DISABLE. These are global USBHOST configurations and are all defined in drivers/usbhost/Kconfig.
lpc17: Correct scope of naming of configuration variables: CONFIG_USBHOST_TDBUFFERS->CONFIG_LPC17_USBHOST_TDBUFFERS, CONFIG_USBHOST_TDBUFSIZE->CONFIG_LPC17_USBHOST_TDBUFSIZE, and CONFIG_USBHOST_IOBUFSIZE->CONFIG_LPC17_USBHOST_IOBUFSIZE

lpc17: Correct scope of naming of configuration variable: CONFIG_USBHOST_OHCIRAM_SIZE->CONFIG_LPC17_OHCIRAM_SIZE
Fix a few typo/compilation problems.
net/: Remove all CONFIG_NET_xxx_TCP_RECVWNDO configuration variables. They were used only to initialize the d_recwndo of the network device structure which no longer exists.
net/: Remove the device TCP receive window field (d_recvwndo) from the device structure. That value is no longer retained, but is calculated dynamically.
Remove some dangling references to CONFIG_NET_TCP_RWND_CONTROL.
net/tcp: Take read-ahead throttling into account when calculating the TCP receive window size.
net/tcp: tcp_get_recvwindow() now returns the receive window size directly (vs. indirectly via the device structure).
net/tcp: Remove CONFIG_NET_TCP_RWND_CONTROL. TCP window algorithm is now trigged only by CONFIG_NET_TCP_READAHEAD.

When reading 1 byte from the SPI device the clock must be enabled and
immediately disabled. This section has been optimized by the compiler (-O2) to a
missing active spi clock. A subsequently block read failed because of missing
response from the spi device. This has been lead to a broken display
initializing.

Fix trivial coding standard issue.
configs/imxrt1050-evk: Correct CONFIG_RAM_SIZE in all configurations (5Kb not 5Mb). I don't believe that CONFIG_RAM_SIZE is used at all in the i.MX RT so this is as grievous an error as it seems. Also enabled built-in applications in all NSH configurations.
