BOOT: Add RAW ramdisk support to bootz
This patch allows loading RAW ramdisk via bootz command. The raw ramdisk is loaded only in case it's size is specified: bootz <kernel addr> <ramdisk addr>:<ramdisk size> <fdt addr> For example: bootz 0x42000000 0x43000000:0x12345 0x44000000 Signed-off-by: Marek Vasut <marex@denx.de> Signed-off-by: Rob Herring <rob.herring@calxeda.com> Cc: Tom Warren <TWarren@nvidia.com> Cc: albert.u.boot@aribaud.net Cc: afleming@gmail.com Cc: Simon Glass <sjg@chromium.org> Cc: Stephen Warren <swarren@nvidia.com> Cc: Nicolas Pitre <nico@fluxnic.net> Cc: Wolfgang Denk <wd@denx.de> Cc: Detlev Zundel <dzu@denx.de>
