| 4 | Subject: [PATCH] powerpc: change the memory size limit |
| 5 | |
| 6 | When run "kexec" in powerpc board, the kexec has a limit that |
| 7 | the kernel text and bss size must be less than 24M. But now |
| 8 | some kernel size exceed the limit. So we need to change the limit, |
| 9 | else will get the error log as below: |
