Subject: [PATCH] powerpc: change the memory size limit
When run "kexec" in powerpc board, the kexec has a limit that
the kernel text and bss size must be less than 24M. But now
some kernel size exceed the limit. So we need to change the limit,
else will get the error log as below:
my_load:669: do
Could not find a free area of memory of 0x12400 bytes...
Could not find a free area of memory of 0x13000 bytes...
locate_hole failed
Upstream-Status: Pending
