This is a supplement to the patch:1936126210a56b6d1b033d6d940669413dd6e1b0
Due to the automatic wrapping of MTD devices during the
open() process, the legacy registration methods
ftl_initialize() and bchdev_register() are no longer
required for MTD device registration for user code.
So we have adjusted the registration method for MTD devices
in nuttx/boards, replacing the previous approach using
ftl_initialize() with register_mtddriver().
We have adjusted the registration method for MTD devices

register_mtddriver().
When registering MTD devices via register_mtddriver(),
FTL and BCH wrappers will be added during the open() process:
1. Character Device Mode:
When accessing the MTD device node via the open() interface,
the device will be automatically converted to a character
device. Both FTL and BCH wrappers will be implicitly added,
provided that BCH support is enabled in the configuration.
2. Block Device Mode:
When accessing the MTD device node via open_blockdriver(),
the device will be treated as a block device, with only
the FTL wrapper automatically applied.
Due to the automatic wrapping of MTD devices during the
open() process, the legacy registration methods
ftl_initialize() and bchdev_register() are no longer
required for MTD device registration for user code and should
be used only internally within fs and driver code.

Use the pins specified in the SAMA5D3 Xplained User Guide.
Rename config macros from SAMA5D4EK to SAMA5D3XPLAINED.
Add SDMMC support to defconfig. Boot mount is disabled by default.
Renaming "modlib" to "libelf" is more in line with the implementation content,
which makes it easier for individual developers to understand the capabilities of this module.
CONFIG_LIBC_MODLIB -> CONFIG_LIBC_ELF

This commit cleans up redundant header file includes throughout the codebase.
The changes include:
- Removing duplicate #include directives that were present in the same file
- Consolidating includes that were split across multiple lines unnecessarily
- Removing unused includes that were no longer needed
- Fixing some formatting issues with includes
The changes improve code organization and maintainability by:
- Reducing unnecessary dependencies
- Making include dependencies more explicit
- Following consistent include patterns
- Removing dead code
No functional changes are made - this is purely a code cleanup commit.

(1) Keep the `.init_array` and `.ctors` symbols and sort them according to their initialization priority.
(2) Exclude symbols ending with crtend.* and crtbegin.* to support c++
application.if we not exclude crtend.* crtbegin.* frame_dummy will be
added when enable any c++ application with global variables, this symbol
execution is problematic, removing it does not affect the application.

This change adds support for the USB Transport Layer as described
in the bluetooth spec. Isochronous endpoints are not yet supported.
Because of limitations in the NuttX bluetooth stack, only one USB
device can be used. This driver will only allow one USB dongle to
use bluetooth.
A Laird USB BT4.2 dongle (from Mouser) was used for testing:
M/N BT851 1.0 1829, FCC ID:SQGBT850
lsusb: 04b4:f901 Cypress Semiconductor Corp. CYW20704A2
The following commands were used to test from the nsh prompt:
bt bnep0 scan start
bt bnep0 scan stop
bt bnep0 scan get
bt bnep0 info
The Linux gatttool was used to connect over wireless.
With the BDAddr found by "bt bnep0 info", start gatttool using:
gatttool -b BDAddr -I
Connect to the device using:
connect
Read the device name using the GAP device name UUID:
char-read-uuid 2a00
Part of the response is:
value: 41 70 61 63 68 65 20 4e 75 74 74 58
which is the string "Apache NuttX"
Usually the startup script is placed under /etc. The contents of the etc directory
are compiled and linked with Nuttx binary in the form of romfs. After startup,
it will be mounted by Nsh.
etc is generated by the different boards, that use genromfs and xxd tools to generate
and compile it into the Nuttx, for example: boards/arm/at32/at32f437-mini/tool/mkromfs.sh
The more common method is etc image generated from the content in the corresponding
board/arch/board/board/src/etc directory, and added by Makefile for example:
boards/sim/sim/sim/src/etc.
But in kernel/protected mode, Nuttx kernel and apps are run in different privileged/
non-privileged mode or the isolated binarys, so as that nsh should use syscall to
access Nuttx kernel by exported API. In this scenario, nsh can not mount the etc image
content, because that is generated in board and as a part of Nuttx kernel.
changes:
- move etc romfs mount from nsh to Nuttx, but keep the script to parse and execute.
- move and rename the related CONFIG, move customized nsh_romfsimg.h to etc_romfs.c
in boards, and no need declaration for romfs_img/romfs_img_len.
This commit changes and updates all configurations in Nuttx arch/board as much as possible,
but if any missing, please refer to the following simple guide:
- rename CONFIG_NSH_ROMFSETC to CONFIG_ETC_ROMFS, and delete CONFIG_NSH_ARCHROMFS in defconfig
- rename the etc romfs mount configs, for example CONFIG_NSH_FATDEVNO to CONFIG_ETC_FATDEVNO
- move customized nsh_romfsimg.h to etc_romfs.c in board/arch/board/board/src and no need
declaration for romfs_img/romfs_img_len.
- delete default nsh_romfsimg.h, if ROMFSETC is enabled, should generate and compile etc_romfs.c
in board/arch/board/board/src.

- migrated /README are removed from /boards
- there are a lot of READMEs that should be further converted to rst.
At the moment they are moved to Documentation/platforms and included in rst files
When I try to set priorities in certain programs, such as init_priority(HIGH_PRIORITY), I've noticed that during linking, there's no guarantee that the programs will be compiled in the sequence I've specified based on priority. This has led to some runtime errors in my program.
I realized that in the ld file, when initializing dynamic arrays, there's no assurance of initializing init_array.* before init_array. This has resulted in runtime errors in the program. Consequently, I've rearranged the init_array.* in the ld file of NuttX to be placed before init_array and added a SORT operation to init_array.* to ensure accurate initialization based on priorities during linking.
replace *(.init_array .init_array.*) with KEEP(*(.init_array .init_array.*)).
The KEEP statement within a linker script will instruct the linker to keep the specified section, even if no symbols inside it are referenced. This statement is used within the SECTIONS section of the linker script. This becomes relevant when garbage collection is performed at link time, enabled by passing the --gc-sections switch to the linker. The KEEP statement instructs the linker to use the specified section as a root node when creating a dependency graph, looking for unused sections. Essentially forcing the section to be marked as used.
