| Series | rockchip: Add Binman support | expand |
Hello, Thank you for the patch set. Currently, I have the following concern about documentation and overall proposed u-boot deploy procedure. There is a use case, when I have to use Rockchip proprietary TPL binary and deploy it instead of u-boot's one together with u-boot SPL and ITB images. It is required for debugging purposes because unfortunately u-boot TPL is usually less stable that proprietary one. And switching the TPL binary is basically the first step when I see random strange crashes. It is a good way to locate an issue origin. Could we somehow ensure that this backup deployment plan is still possible and documented in the text here? It would be great if the user could learn the procedure from the text, not from the source code, recovering correct offsets. пн, 30 дек. 2019 г. в 11:28, Jagan Teki <jagan@amarulasolutions.com>: > > Rockchip has documentation file, doc/README.rockchip but > which is not so readable to add or understand the existing > contents.

You mean to say rkbin => SPL => U-Boot proper ? if yes, I do agree with this point and it is worth to document it as well. Kever, will that be okay for you? Jagan.

Rockchip has documentation file, doc/README.rockchip but which is not so readable to add or understand the existing contents. Even the format that support is legacy readme in U-Boot. Add rockchip specific documentation file using new rst format, which describes the information about Rockchip supported boards and it's usage steps. Added minimal information about rk3288, rk3328, rk3368 and rk3399 boards and usage. This would indeed updated further based on the requirements and updates.
