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.

I think you can just remove the memory from the system memory map in the
device tree and pretend it only starts after the bootloader. It's been a while
since I looked at this though, so I could be misremembering what the minimum
boundaries are for doing this.
