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
