24985686fe arm64: dts: imx8mp: Add DT overlay describing i.MX8MP DHCOM SoM rev.100
The current imx8mp-dhcom-som.dtsi describes production rev.200 SoM,
add DT overlay which reinstates rev.100 SoM description to permit
prototype rev.100 SoMs to be used until they get phased out.

ad1158c50e arm64: dts: imx8mp: Switch to DT overlays for i.MX8MP DHCOM SoM
Add DT overlays to support additional DH i.MX8MP DHCOM SoM 660-100
population options with 1x or 2x RMII PHY mounted on PDK2 or PDK3
carrier boards.

Use SPL DTO support to apply matching SoM specific DTO to cater
for the SoM differences. Remove ad-hoc patching of control DT from
fdtdec_board_setup().

506df9dc58 treewide: rework linker symbol declarations in sections header
1. Convert all linker symbols to char[] type so that we can get the
   corresponding address by calling array name 'var' or its address
   '&var'. In this way, we can avoid some potential issues[1].
2. Remove unused symbol '_TEXT_BASE'. It has been abandoned and has
   not been referenced by any source code.
3. Move '__data_end' to the arch x86's own sections header as it's
   only used by x86 arch.
4. Remove some duplicate declared linker symbols. Now we use the
   standard header file to declare them.

[1] This patch fixes the boot failure on MIPS target. Error log:
SPL: Image overlaps SPL

Fixes: 1b8a1be1a1 ("spl: spl_legacy: Fix spl_end address")

f8e413208f ARM: imx: Add 2 GiB DRAM support for DH electronics i.MX8M Plus DHCOM
The DH electronics i.MX8M Plus DHCOM SoM currently supports only 4 GiB
of DRAM population option. Add another population option with 2 GiB of
DRAM. The chips used on the 2 GiB option are 2x K4F6E3S4HM-MGCJ .

a20be24cd4 ARM: imx: Remove PMIC reset configuration from board files
The PCA9450 reset configuration can now be performed by the PCA9450 PMIC
driver itself, remove the hard-coded variant from board code and let the
PMIC driver perform this task using one-liner:

```
$ sed -i '/set WDOG_B_CFG to cold reset/,+2 d' $(git grep -l PCA9450_RESET_CTRL.*0xA1 board/)
```

Venice and i.MX93 EVK required slight manual fix up.
