[PATCH v5 0/6] rockchip: Use external TPL binary to create a working firmware image

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
- New patch to sync init size limit in mkimage
- New RFC patch to improve allow-missing/fake-ext-blobs handling for
  binman mkimage entry
