Comment(by lindi):

 I tried mem=120M and writing to 123<<20 just in case but this did not make
 any difference.

 I also tried changing the memory from uboot

 {{{
 GTA02v5 # base 0x30000000
 Base Address: 0x30000000
 GTA02v5 # md 0x087b00000 4
 b7b00000: ffffffff ffffffff ffffffff ffffffff    ................
 GTA02v5 # mw 0x087b00000 1 1
 GTA02v5 # md 0x087b00000 4
 b7b00000: 00000001 ffffffff ffffffff ffffffff    ................
 }}}

 but still only saw zeroes under linux. So either something is zeroing the
 memory during boot or I am writing/reading a completely wrong memory
 address?
