Subject: [PATCH v2 05/13] MIPS: generic: Allow boards to set system type

Check for the (already existing) "system_type" variable in the
get_system_type() function. If non-NULL, return it as the system type.

Signed-off-by: Paul Cercueil <>

    v2: Instead of adding a .get_system_type callback to the mips_machine
        struct, the boards now simply override the "system_type" variable
    	when they want to set a custom one.
