Julius Werner 027b728d4a Add support for LZ4 decompression algorithm 
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.

* below this.

* starts allocating space from 64 bytes below @top. First it creates space
* for global_data. Then it calls arch_setup_gd() which sets gd to point to
* the global_data space and can reserve additional bytes of space if
* required). Finally it allocates early malloc() memory
* (CONFIG_SYS_MALLOC_F_LEN). The new top of the stack is just below this,
* and it returned by this function.
*
* [1] Strictly speaking it would be possible to implement this function
* in C on many archs such that it does not require a stack. However this
* does not seem hugely important as only 64 byte are wasted. The 64 bytes
* are used to handle the calling standard which generally requires pushing
* addresses or registers onto the stack. We should be able to get away with
* less if this becomes important.
