This cap of Malta memory size to 0x7fff0000 was added by commit
e6ca4e5bf114 "MIPS: malta: malta-memory: Add support for the 'ememsize'
variable" as part of support for EVA, with only the cryptic comment
"Last 64K for HIGHMEM arithmetics". However
- EVA is used to avoid highmem, both are not enabled at once which
makes the comment about highmem macros nonsensical.
- I can think of no good reason for it, and nor could anyone else I
asked.
So remove this memsize limit.
