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.
