Support u-boot noload images for arm as used by, NetBSD/evbarm GENERIC kernel.
noload kernels are loaded with the u-boot image header and as a result the header size needs adding to the entry point. Fake up a hdr so the kernel image is loaded at the right address and the entry point is adjusted appropriately. The default location for the uboot file is 32MiB above bottom of DRAM. This matches the recommendation in Documentation/arm/Booting. Clarify the load_uimage API to state the passing of a load address when an image doesn't specify one, or when loading a ramdisk is expected. Adjust callers of load_uimage, etc. Signed-off-by: Nick Hudson <skrll@netbsd.org> Message-id: 11488a08-1fe0-a278-2210-deb64731107f@gmx.co.uk Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
