| 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 |
