* env_eeprom.c: Correct using saved environmentLudger Dreier2015-10-12-89/+77
| | | | | | | | | The changes in ed6a5d4 unintentionally broke support for reading the environment saved to eeprom back. To correct this the crc-check and decision on which environment to use is now moved to env_relocate_spec. This is done for both the "redundant env" and the "single env" case.

* common/image.c: Make boot_get_ramdisk() perform a check for Android imagesTom Rini2015-10-11-0/+9
| | | | | | | | | | | | | | | In 2dd4632 the check for where a ramdisk is found on an Android image was got moved into the "normal" loop here, causing people to have to pass the kernel address in the ramdisk address location in order to have Android boot still. This changed previous behavior so perform a check early in the function to see if we have an Android image and if so use that as where to look for the ramdisk (which is what the rest of the code here expects). We allow for this to still be overridden with an explicit ramdisk address to be passed as normal.

* Add support for LZ4 decompression algorithmJulius Werner2015-10-11-0/+10
| | | | | | | | | | | | | | | This patch adds support for LZ4-compressed FIT image contents. This algorithm has a slightly worse compression ration than LZO while being nearly twice as fast to decompress. When loading images from a fast storage medium this usually results in a boot time win. Sandbox-tested only since I don't have a U-Boot development system set up right now. The code was imported unchanged from coreboot where it's proven to work, though. I'm mostly interested in getting this recognized by mkImage for use in a downstream project. Signed-off-by: Julius Werner <jwerner@chromium.org> Acked-by: Simon Glass <sjg@chromium.org>

* net: avoid eth_unregister() call when function is unavailableBernhard Nortmann2015-09-29-0/+2
