Rockchip SoCs typically use U-Boot TPL to initialize DRAM, then jumps back to BootRom to load next stage, U-Boot SPL, into DRAM. BootRom then jumps to U-Boot SPL to continue the boot flow.
For RK356x there is no support to initialize DRAM using U-Boot TPL and instead an external TPL binary must be used to generate a bootable u-boot-rockchip.bin image.
This adds a new rockchip-tpl entry to binman and make use of this new entry in rockchip-u-boot.dtsi.
Build U-Boot with ROCKCHIP_TPL=/path/to/ddr.bin to generate a bootable u-boot-rockchip.bin image for RK356x.
The last patch fixes an allow-missing issue for mkimage entry, something that needs to be working for CI pipeline. The patch is based on [1] from the "binman: Show missing blob message" series at [2].
Changes in v5: - Add patch to fix issue with allow-missing - Split init size limit patch in two
Changes in v4: - Only change init size limit for rk3328 and rk3568 - Drop update evb-rk3568_defconfig patch
Changes in v3: - Move test function last - Add help text to Kconfig option - Add build step for rk3568 to documentation - Resync init size limit table - Drop missing message RFC patch
Changes in v2: - Renamed external-tpl to rockchip-tpl - Renamed EXTERNAL_TPL to ROCKCHIP_TPL - Add CONFIG_ROCKCHIP_EXTERNAL_TPL Kconfig option - New patch to sync init size limit in mkimage - New RFC patch to improve allow-missing/fake-ext-blobs handling for binman mkimage entry
