type field contains e820 type ids, which are used by coreboot and multiboot (the two source formats), so they can be used as-is. The MEMMAP_RAM_ONLY define is a way to allow a payload to opt for only having CB_MEM_RAM type fields, which might be helpful to support older payloads easily (just add the define, and it won't encounter "weird" fields) Signed-off-by: Patrick Georgi <patrick.georgi@coresystems.de> Acked-by: Peter Stuge <peter@stuge.se> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@4291 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
