This patchset adds the support on Rockchip based RK3399 and RK3328 SOC's
that compress the U-BOOT proper along with dtb and ATF in FIT image format.
Second stage bootloader(SPL) loads the compressed binaries, uncompress them and
handover control to the next stage.
The size difference observed between uncompressed and compressed FIT images is
nearly 67
to 70% and used two compression libraries,LZMA and GZIP.
Patch 1/10 generate a GZIP-compressed raw U-boot binary using Makefile
Patch 2/10 address to store compressed U-BOOT raw binary using Kconfig
Patch 3/10 RAM location to store compressed U-BOOT raw binary for ROCKCHIP
based RK3399 and RK3328 SOC's
Patch 4/10 uncompress the gzip U-BOOT binary and load the binaries if gzip
compression supoort is enabled
Patch 5/10 generate a LZMA-compressed raw U-boot binary using Makefile
Patch 6/10 uncompress the lzma U-BOOT binary and load the binaries if lzma
compression supoort is enabled
Patch 7/10 add u-boot-nodtb.bin.gz as an input binary in binman
Patch 8/10 add the GZIP compressed uboot raw binary to FIT image
Patch 9/10 add u-boot-nodtb.bin.lzma as an input binary in binman
Patch 10/10 add the LZMA compressed uboot raw binary to FIT image
