Hi,
this is meant as a status update and possible discussion for the core parts if needed.
After talking with Simon and Tom the order is now also correct with tpl -> spl -> uboot.
Status right now is:
- the full uboot still works
- the tpl/spl does start and is able to configure the ddr into a working state
- The jump spl -> bootrom -> uboot doesn't work though
On the other hand, Kever was able to make this work, booting from nand when building the image with a very ancient tool.
All newer tools (including boot_merger.c from Rockchip's uboot) do not produce working images. But it is possible to produce a working sd-boot image using the proprietary 1st-stage loader.
See the temporary mkuboot script in the last patch, which can create both types of images now (especially wrt. the needed rc4 encryption of everything).
Combining this (it does work using some special tool), it looks like there is still some minor glitch in the way we build the spl image somewhere.
What should we do with this series? There are a few minor things to resolve but other than that, do you think it is ready to apply?
The above problem could perhaps be resolved later if there is a suitable README describing it?
Regards, Simon
