This patchset adds the support on Rockchip based ARM64 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.
Changes for V2 :-
- Removed the need to create gzip and lzma compressed U-boot-nodtb files using
Makefile and added a changeset
that "compress" field to u-boot-nodtb node and "compression" field to u-boot
Node in the FIT image, with the help
of this change binman will create the compressed Binaries.
Size Comparision between compressed and uncompressed binaries :-
size of uncompressed binary :- 9.4??MB (94,26,432 bytes)
manoj:u-boot$ ls -lb u-boot-rockchip.bin
-rw-rw-r-- 1 manoj manoj 9426432 Jul 25 07:42 u-boot-rockchip.bin
size of GZIP compressed binary :- 9.0??MB (89,85,088 bytes)
manoj:u-boot$ ls -lb u-boot-rockchip.bin
-rw-rw-r-- 1 manoj manoj 8985088 Jul 25 07:42 u-boot-rockchip.bin
size of LZMA compressed binary :- 9.0??MB (90,06,080 bytes)
manoj:u-boot$ ls -lb u-boot-rockchip.bin
-rw-rw-r-- 1 manoj manoj 9006080 Jul 25 07:47 u-boot-rockchip.bin
- modified to use the CONFIG_SYS_LOAD_ADDR as the source RAM address to store
the compressed U-Boot binary which
will be defined in the machine defconfig file in place of creating a new RAM
address for a specific board using Kconfig.
so patchset related to adding a new RAM address to store compressed binary has
been removed in V2 patchset.
- Removed the patchset related to adding the u-boot-nodtb.bin.gz and
u-boot-nodtb.bin.lzma as input binary to binman.
