[U-Boot] MPC8xx malloc failing

[saugat mitra]

Hi

I have moved onto 2009.11, though more new versions are available but still ..
I am using a MPC8XX based board( as earlier), but now the code is crashing
in env_relocate() function. On applying debug prints I found that the
code was failing
in malloc with a Bus Fault with the following dump -

Bus Fault @ 0x00fc9988, fixup 0x00000000
