This is in the wrong place: move the Kconfig entry into
arch/arm/mach-sunplus/Kconfig
and make it 'depends on ARCH_MULTI_V7'.

I think you can remove all the 'select' lines as well because they are
either implied by
ARCH_MULTI_V7 or not actually necessary.

Thanks for your review, I'll correct these at next commit.

What is this needed for? If it boots without this line, better avoid
adding it, because
it will increase the kernel size for everyone else (unless they also enable
AXXIA).

SP7021 reserved the 1st 1MB memory for ARM926@P-Chip using,
The 2nd 1MB memory for IOP device and the 3rd 1MB memory for bootloader.
I'll add these comments at next commit.
