Disable arch_fixup_fdt() calls for cases where U-Boot shouldn't update
memory setup in DTB file.
One example of usage of this option is to boot OS with different memory
setup than U-Boot use.

Could we instead just have the board file provide a fixup? It could then
also fix up the efi memory map.
Not sure what exactly you are asking for.
Do you mean to add fixup function to board file and overwrite default one?
You have to touch some other code anyway to make this work with a
particular board, right? In that case, you can as well add a function to
the board file that explicitly provides a different, known good memory map.
Can you have a weaker overload? Basically I would like to have a board
provide arch_fixup_fdt() which would override the one in bootm-fdt.c.
But we can also rename arch_fixup_fdt() in bootm-fdt.c to
board_fixup_fdt() function, declare it weak and have arch_fixup_fdt()
call that.
