This patch add auto parse the compress format of kernel image.
Then decompress the compressed kernel image for arm64, as for
arm32 zImage, we only need to load it to a higher memory, then
the kernel will handle the decompress itself.
Test on RK3308 AARCH64 mode (Cortex A35 816 MHZ) boot with eMMC:
------------------------------------------------------------------
Format | Size(Byte) | Ratio | Decomp time(ms) | Boot time(ms) |
-------------------------------------------------------------------
Image | 7720968 | | | 488 |
-------------------------------------------------------------------
Image.lz4 | 4119448 | 53% | 59 | 455 |
-------------------------------------------------------------------
Image.lzo | 3858322 | 49% | 141 | 536 |
-------------------------------------------------------------------
Image.gz | 3529108 | 45% | 222 | 609 |
-------------------------------------------------------------------
Image.bz2 | 3295914 | 42% | 2940 | |
-------------------------------------------------------------------
Image.lzma| 2683750 | 34% | | |
-------------------------------------------------------------------
Note: the boot time is counted from first ddr init log to first Kernel log.

gcc 4.4.3 (which is the default native compiler on x86-64 Ubuntu 10.04)
doesn't seem to like initializers for sub-fields of anonymous unions.
Solve this by replacing the initialization with an assignment. This
fixes:
lib/lz4_wrapper.c: In function ‘ulz4fn’:
lib/lz4_wrapper.c:97: error: unknown field ‘raw’ specified in initializer

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.
