Use the bootz command to load zImages in case of any new boot scripts. Only the legacy one will still use bootm. Apart form the fact, that this will simplify the image generation process, it saves one copy of the kernel image: Common practice is to generate an uImage with a loading address of 0x8000. This uImage contains a compressed zImage, which will unpack the kernel image to the beginning of the RAM. But because there is already the compressed image the uncompressor first relocates the compressed image to a higher location. The load address is encoded into the uImage which is generated by the distributions and thus cannot be easily changed. By using the bootz command we can load the compressed image to a higher memory address and the decompressor doesn't have to reloacte the image. Signed-off-by: Michael Walle <michael@walle.cc>
