lib/bootmem: Add more bootmem tags
Introduce new bootmem tags to allow more fine grained control over buffer allocation on various platforms. The new tags are: BM_MEM_RAMSTAGE : Memory where any kind of boot firmware resides and that should not be touched by bootmem (by example: stack, TTB, program, ...). BM_MEM_PAYLOAD : Memory where any kind of payload resides and that should not be touched by bootmem. Starting with this commit all bootmem methods will no longer see memory that is used by coreboot as usable RAM. Bootmem changes: * Introduce a weak function to add platform specific memranges. * Mark memory allocated by bootmem as BM_TAG_PAYLOAD. * Assert on failures. * Add _stack and _program as BM_MEM_RAMSTAGE. ARMv7 and ARMv8 specific changes: * Add _ttb and _postram_cbfs_cache as BM_MEM_RAMSTAGE. ARMv7 specific changes: * Add _ttb_subtables as BM_MEM_RAMSTAGE.
