This patch set add zip command support for uboot.
The first two patches import deflate and trees functions from zlib 1.2.5 without any change. While the third patch did the necessary change to make the import file could be built passed in uboot environment.

The fourth patch make us could zip the memory from 0 in the address space.

The latter fifth and sixth patch does the adding gzip lib function exporting and zip command support.

Patch set test with zip&unzip and compared with original memory content.

lib: zlib: import deflate source file from 1.2.5
lib: zlib: import trees file from 1.2.5
lib: zlib: include deflate into zlib build
lib: zlib: remove the limitation for cannot using 0 as start
lib: add gzip lib function callback

Are there any users for this code? What is it for ?

This patch was intended to compress the memory when uploading through USB. So that uploaded image could be smaller. Maybe there are some other usage, like memory testing?

CCing Lukasz, maybe he can find some use for this in the DFU series?
