    Subject[PATCH 5/5] MIPS: Allow kernel base to be set from Kconfig for all platforms
    Date
    There are some platforms in wild that generic loading address won't
    work with them due to memory layout.

    Allow PHYSICAL_START to be override from Kconfig, introduce
    PHYSICAL_START_BOOL symbol as powerpc did.

    If you plan to use kernel for capturing the crash dump change
    this value to start of the reserved region (the "X" value as
    specified in the "crashkernel=YM@XM" command line boot parameter
