(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 adds enablers for setting various clocks to some default
values. Also, this provides helpers to grant nonsecure access
to a number of clocks. Bootloader may utilize these to make
the system boot in a deterministic manner.

This provides a capable bootloader that may be run from OCRAM.
The OCRAM contains regions that are always zero, so the linker
file avoids those with best effort.
iMX9 infrastructure expects:
- 0x20480000 (Start of OCRAM, AHAB)
- 0x2049a000 (NuttX or SPL)
- 0x204e0000 (ARM Trustzone, not used)
When started from SD-card, the offsets are:
- 0x1f000 with AHAB
- 0xa000 without AHAB

Add a simple allocator for DMA safe memory. It will provide contiguous
blocks of memory with D-Cache line size alignment.
NOTE: The optimal granule size is the D-Cache line size (64), but due
to restrictions in the granule allocator this would result in a maximum
block size of 2K only, thus use 256B granules instead givin 8K max block
size.
Once the granule allocator is fixed this limitation can be removed.
These configs are changed based on below rules.
1. always enable +CONFIG_LV_USE_NUTTX=y
2. If touchpad is used, enable +CONFIG_LV_USE_NUTTX_TOUCHSCREEN=y
3. enable log by +CONFIG_LV_USE_LOG=y
4. If -CONFIG_LV_MEM_CUSTOM=y previously defined, replace it with +CONFIG_LV_USE_CLIB_MALLOC=y +CONFIG_LV_USE_CLIB_SPRINTF=y +CONFIG_LV_USE_CLIB_STRING=y
5. If -CONFIG_LV_PORT_USE_FBDEV=y, default config is for fbdev. If -CONFIG_LV_PORT_USE_LCDDEV=y, +CONFIG_LV_USE_NUTTX_LCD=y
6. Remove all -CONFIG_LV_TICK_CUSTOM=y -CONFIG_LV_TICK_CUSTOM_INCLUDE="port/lv_port_tick.h"
7. If -CONFIG_LV_PORT_LCDDEV_DOUBLE_BUFFER=y, replace it with CONFIG_LV_NUTTX_LCD_DOUBLE_BUFFER=y. For fbdev, double buffer is automatically detected.
8. If -CONFIG_LV_COLOR_16_SWAP=y, need to upgrade the LCD driver to support hardware byte order swap.

This patch adds a way to configure PLL frequencies. The configuration is
given by board logic.
These values should only be modified by the bootloader, but we don't have
that yet so the flag is never activated.

As __start must be placed at a precise location, a separate, explicit
input section is needed to guarantee this.
Why is this an issue ? NuttX uses --entry=__start which puts __start in
its correct location, but out-of-tree builds won't work, so it more robust
to use an explicit section for the startup code and enforce its placement
in the linker script.
Adds board definition for imx93-evk board
- Support for the Cortex-A55 core in i.MX93, support for the Cortex-M33
core is _not_ provided
- "nsh" profile is provided, this includes a minimalistic feature set
which boots the SoM to nsh console
- A bootloader is required, u-boot has been tested
Summary:
- This commit adds nxrecorder to netnsh/netnsh_hv/netnsh_smp/
netnsh_smp_hv defconfigs.
Impact:
- None
Testing:
- Tested with qemu-8.2.0 on Raspi4B with USB Audio

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.

- there are a lot of READMEs that should be further converted to rst.
