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.
How much does this size difference and decompression affect boot times?
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
Instead of adding Makefile targets and custom binman etypes adding support for on-the-fly compression to the fit etype if probably a better option. E.g. when fit node has compression <> none, compress the data content inside binman instead of relaying on binman nodes and Makefile output.
