[PATCH v5 4/5] MIPS: kexec: Relax memory restriction

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We can rely on the system kernel and the dump capture kernel themselves in
memory usage.

Being restrictive with 512MB limit may cause kexec tool failure on some
platforms.
