One of the majore things needed on the BSP used to be lzma decompression
which put a 16K array on the stack. We fixed this a while ago, bringing
down stack usage on our Intel based boards to about 1K (and giving each
core a 4K stack)

We fixed the issue by putting that big array in the heap instead. Maybe
we can fix the AMD code in the same way.

I would like to see some actual stack usage data first though
