mips: clean up kernel-doc in cavium-octeon/*.c

2021-07-28T09:22:21Z

Convert function comments to kernel-doc notation to remove kernel-doc warnings in arch/mips/cavium-octeon/*.c. Also clean up the comments in a few places. arch/mips/cavium-octeon/flash_setup.c:66: warning: This comment starts with '/**', but isn't a kernel-doc comment.

Revert "MIPS: Octeon: Remove special handling of CONFIG_MIPS_ELF_APPENDED_DTB=y"

2021-01-19T22:03:18Z

This reverts commit d9df9fb901d25b941ab2cfb5b570d91fb2abf7a3. For the OCTEON boards, it need to patch the built-in DTB before using it. Previously it judges if it is a built-in DTB by checking fw_passed_dtb. But after commit 37e5c69ffd41 ("MIPS: head.S: Init fw_passed_dtb to builtin DTB", the fw_passed_dtb is initialized even when using built-in DTB. This causes the OCTEON boards boot broken due to an unpatched built-in DTB is used. Revert the commit d9df9fb901d2 to restore the codes before the fw_passed_dtb is used and then fix this issue.

MIPS: replace add_memory_region with memblock

MIPS: OCTEON: fix kexec support

2019-01-14T21:51:03Z

Commit 62cac480f33f ("MIPS: kexec: Make a framework for both jumping and halting on nonboot CPUs") broke the build of the OCTEON platform as the relocated_kexec_smp_wait() is now static and not longer exported in kexec.h. Replace it by kexec_reboot() like it has been done in other places.
