Subject: [PATCH 0/4] MIPS: Simplify ELF appended dtb handling

Hi,

This patch series simplifies and cleans up the handling of
CONFIG_MIPS_ELF_APPENDED_DTB in the MIPS tree.

Specifically, it makes sure that the dtb appears in 'fw_passed_dtb'
also under CONFIG_MIPS_ELF_APPENDED_DTB=y.

This allows to remove special platform code that handled the ELF
appended dtb case, and replace it with the generic appended dtb
case (fw_passed_dtb).

There's also a bonus: platforms that already handle 'fw_passed_dtb',
gain now automatic support for detecting a DT blob under
CONFIG_MIPS_ELF_APPENDED_DTB=y.


Patches:
- Patch 1 adds only comments (to make the file more readable for patch 2).
- Patch 2 fixes 'fw_passed_dtb' under CONFIG_MIPS_ELF_APPENDED_DTB=y.
- Patch 3 simplifies CONFIG_MIPS_ELF_APPENDED_DTB handling on the BMIPS platform.
- Patch 4 simplifies CONFIG_MIPS_ELF_APPENDED_DTB handling on the Octeon platform.

Patches 3 and 4 depend on patch 2.

The patches are on top of v4.18.

The patches are also available at:
https://github.com/yashac3/linux-rtl8186/commits/elf_appended_dtb_changes_on_4_18

Please review.

Thanks,
Yasha
