[PATCH v2 06/32] lmb: make LMB memory map persistent and global

The current LMB API's for allocating and reserving memory use a per-caller based memory view. Memory allocated by a caller can then be overwritten by another caller. Make these allocations and reservations persistent using the alloced list data structure.

Two alloced lists are declared -- one for the available(free) memory, and one for the used memory. Once full, the list can then be extended at runtime.

Signed-off-by: Sughosh Ganu sughosh.ganu@linaro.org Signed-off-by: Simon Glass sjg@chromium.org [sjg: Optimise the logic to add a region in lmb_add_region_flags()] --- Changes since V1: * Keep the alloced lists for used and free memory in a lmb structure. * s/lmb_mem_regions_init/lmb_setup. * Remove the special case scenario for adding region when list is empty(sjg). * Optimise the logic to add a region to a sorted region list(sjg) * Call lmb_setup() from lmb_init()
