This port was effort of a number of people, I rather arbitrarily gave authorship to Guiding Li because he has the largest number of fundamental quashed commits from the Xiamoi repository.
Squashed commit of the following:
Author: Xiang Xiao <xiaoxiang@pinecone.net>
include/nuttx/b2c.h and libx/libc/string: Add non-standard string functions to deal with cases where there are more than 8-bits in a type char.
Author: Gregory Nutt <gnutt@nuttx.org>
Fix several build issues/missing definitiona needed for OpenAMP build in drivers/.
Add OpenAMP code has been reviewed and ran through tools/nxstyle (with all reports accounted for).
Author: Xiang Xiao <xiaoxiang@xiaomi.com>
tools/: Fix the minor issue in Makefile
Author: Gregory Nutt <gnutt@nuttx.org>
drivers/rptun/rptun.c: Review for coding standard. Run against tools/nxstyle.
tools/LibTargets.mk: Fix some TABs that were turned into spaces by a copy-paste.
fs/hostfs: Add configure and build support for hostfs RPC.
drivers/timer: Add configure and build support for syslog RTC.
drivers/syslog: Add configure and build support for syslog RPC.
drivers/serial: Add configure and build support for serial RPC.
Kconfig, tools/*.mk. openamp/: Add basic OpenAMP build support.
drivers/rptun: Add configure and build support for OpenAMP tunnel drivers.
drivers/net: Update Make.defs and Kconfig for OpenSDA support.
Remove drivers/clk/clk-rpmsg.c drivers/power/rpmsg_regulator.c. These depend on upstreaming support for a new subsystem based on the clk/regulator is model from Linux. Removed because we want to separate the activities. We will just try to get the basic OpenAMP support in place for now.
Remove drivers/misc/misc_rpmsg.c and include/nuttx/misc/misc_rpmsg.h. These are specific to the Xiaomi application.

board/boarctl.c: Add support for the new BOARDIOC_ROMDISK command. This allows applications to create ROMFS block drivers without illegal direct calls to romdisk_register.
include/sys/boardctl.h: Add basic definitions to support a ROM disk creation boardctl() command.
Squashed commit of the following:
drivers/: Run tools/nxstyle against all drivers/*.c.
boards/boardctl.c: Add new boardctl() command, BOARDIOC_MKRD, that can be used to create a RAM disk. This will replace the illegal call to ramdisk_register() currently used by NSH.
drivers/mkrd.c: Add wrapper around ramdisk_register() for creating a proper ramdisk.
According to earlier standards, usage of select(), FD_CLR, FD_ISSET, FD_SET and FD_ZERO
just need include headers: sys/time.h, sys/types.h and unistd.h. So include sys/select.h
in time.h to compatible with it. Or mbedtls library would build break in calling select()
and FD_* related functions.

Most of the bluetooth and wifi chips appear to need external firmware, and the 43438 is no exception. Fortunately, since Cypress got involved, these are much more straightforward to obtain and are shipped as part of their SDK, which is downloadable from their website. Those firmwares are already provided as C arrays, so their names just need updating to;
const unsigned char bt_firmware_hcd -> The bt firmware array.
const int bt_firmware_len = sizeof(bt_firmware_hcd);

task_spawn() and posix_spawn() are NuttX OS interfaces. In PROTECTED and KERNEL build modes, then can be reached from applications only via a system call. Currently, the number of parameters in a system call is limited to six; these spawn function have seven parameters. Rather than extend the maximum number of parameters across all architectures, I opted instead to marshal the seven parameters into a structure.
*
In order to support builtin in function in protected mode, a task_spawn() system call must be supported. Unfortunately this is overly complex because there is a (soft) limit of 6 parameters in a system call; task_spawn has seven paramters. This is a soft limit but still difficult to extend because it involves assembly language changes to numerous architectures. Better to get more creative.
Squashed commit of the following:
Correct some additional compile-related issues.
Move include/nuttx/binfmt/builtin.h to include/nuttx/lib/builtin.h. Move apps/builtin/lib_builtin_forindex.c to libs/libc/builtin/lib_builtin_forindex.c.
Move binfmt/libbuiltin to libs/libc/builtin. There are calls made directly from apps/nshlib into this logic and hence, must be part of a library that can be shared between the OS and applications.

This change introduces IEEE802154_ATTR_PHY_FCSLEN which the radio layer can support to set/get the FCS length that's added to the end of the frame. One use case, in promiscuous mode, is to add back in the FCS of the received frame by increasing the iob->io_len by the FCS length.

Added stubbed implementations of getpwuid, getpwuid_r, getpwnam, and
getpwnam_r. These functions are essentially stubs pretending that NuttX
supported users and that the only configured user in the system was 'root'
with uid 0. The intend is not to provide meaningful new features, but to ease
porting of foreign source code to NuttX.
- Added an alphasort implementation
- Added a scandir implementation
- Added DT_* literals to include/dirent.h: Apparently those are not required by POSIX, but are part of 4.3BSD and available in glibc as well.
Libwebsockets initializes the 'sin_zero' member of sockaddr_in objects to zeros.
Apparently, judging from mailing list entries, there are platforms on which incliinclunot
doing this causes undefined behaviour.
On NuttX compiling respective code is broken, as the corresponding member
variable is called '__pad'. Neither in the 'nuttx' nor in the 'apps'
respository did I find any reference to this identifier. Thus, I believe its a
safe bet to just rename it.
UNIX Network Programming states in this regard:
"The POSIX specification requires only three members in the structure: sin_family,
sin_addr, and sin_port. It is acceptable for a POSIX-compliant implementation to
define additional structure members, and this is normal for an Internet socket
address structure. Almost all implementations add the sin_zero member so that all
socket address structures are at least 16 bytes in size."
Testing of the WiFi is minimal so far but functionality is proven. I'm specifically not happy that the driver doesn't recover elegantly from a DMA data checksum failure, but that is an issue that can be dealt with in due course ... I'm trying to get the rest of the interfaces fleshed out and the hardware proven so it can go for pre-production build. I _think_ there's only Bluetooth and USB-device left to implement now.
