metag: Boot Add boot code for metag. Due to the multi-threaded nature of Meta it is not uncommon for an RTOS or bare metal application to be started on other hardware threads by the bootloader. Since there is a single MMU switch which affects all threads, the MMU is traditionally configured by the bootloader prior to starting Linux. The bootloader passes a structure to Linux which among other things contains information about memory regions which have been mapped. Linux then assumes control of the local heap memory region. A kernel arguments string pointer or a flattened device tree pointer can be provided in the third argument. Signed-off-by: James Hogan <james.hogan@imgtec.com>
