Subject: [PATCH RFC] OMAP2PLUS: Enable HIGHMEM
HIGMEM support is kernel is quite mature now and we have boards
[sp] ^^ replace with "in"
yep. I sent that update in next email.
like ZOOM, PANDA, SDP where 1 GB memories are installed.
Enable HIGMEM to make use of the additional memory.

This won't boards which doesn't have excess memory. Tested
on OMAP4430 SDP
[sp] Comment is unclear on what happens on the boards with
lesser memories esp. since the change will impact all
boards. You may want to explain.
On the boards which doesn't have more than 768 MB memory, all the memory
is directly mapped in "lowmem" and highmem isn't exercised.
