i have started by attempting to move static kernel mapping from lowmem
to vmalloc space. At boot the execution so far has went past assembly
& reached C, to be specific, arm_memblock_init [in setup_arch()],
currently debugging the hang that happens after that point. To make
things easier in the beginning, ARM_PATCH_PHYS_VIRT is disabled &
platform specific PHYS_OFFSET is fed, this is planned to be fixed once
it boots.

[ i will probably start a new thread or hopefully RFC on LAKML ]

Regards
afzal
