image: add support for Android's boot image format This patch adds support for the Android boot-image format. The header file is from the Android project and got slightly alterted so the struct + its defines are not generic but have something like a namespace. The header file is from bootloader/legacy/include/boot/bootimg.h. The header parsing has been written from scratch and I looked at bootloader/legacy/usbloader/usbloader.c for some details. The image contains the physical address (load address) of the kernel and ramdisk. This address is considered only for the kernel image. The "second image" defined in the image header is currently not supported. I haven't found anything that is creating this. v3 (Rob Herring): This is based on http://patchwork.ozlabs.org/patch/126797/ with the following changes: - Rebased to current mainline - Moved android image handling to separate functions in common/image-android.c - s/u8/char/ in header to fix string function warnings - Use SPDX identifiers for licenses - Cleaned-up file source information: android_image.h is from file include/boot/bootimg.h in repository: https://android.googlesource.com/platform/bootable/bootloader/legacy The git commit hash is 4205b865141ff2e255fe1d3bd16de18e217ef06a usbloader.c would be from the same commit, but it does not appear to have been used for any actual code. v4: - s/andriod/android/ - Use a separate flag ep_found to track if the entry point has been set rather than using a magic value.

image-fit: Fix fit_get_node_from_config semantics Commit bac17b78dace ("image-fit: switch ENOLINK to ENOENT") changed fit_get_node_from_config to return -ENOENT when a property doesn't exist, but didn't change any of its callers which check return values. Notably it didn't change boot_get_ramdisk, which leads to U-Boot failing to boot FIT images which don't include ramdisks with the following message: Ramdisk image is corrupt or invalid It also didn't take into account that by returning -ENOENT to denote the lack of a property we lost the ability to determine from the return value of fit_get_node_from_config whether it was the property or the configuration node that was missing, which may potentially lead callers to accept invalid FIT images. Fix this by having fit_get_node_from_config return -EINVAL when the configuration node isn't found and -ENOENT when the property isn't found, which seems to make semantic sense. Callers that previously checked for -ENOLINK are adjusted to check for -ENOENT, which fixes the breakage introduced by commit bac17b78dace ("image-fit: switch ENOLINK to ENOENT"). The only other user of the return fit_get_node_from_config return value, indirectly, is bootm_find_os which already checked for -ENOENT. From a read-through of the code I suspect it ought to have been checking for -ENOLINK prior to bac17b78dace ("image-fit: switch ENOLINK to ENOENT") anyway, which would make it right after this patch, but this would be good to get verified by someone who knows this x86 code or is able to test it.
