[PATCH v5 0/7] rockchip: Add Binman support
This is v5 set for Binman support in rockchip, [1] here is previous patchset.
This series add single boot image with binman for arm32 and pad_cat for arm64 rockchip platforms both TPL + SPL and SPL-alone targets.
Changes for v5: - collect kever review tag - drop idbloader.img from clean target Changes for v4: - support all rockchip platforms - add new patches for dtsi changes - update documentation - format proper commit message - rebase on master Changes for v3: - rebase on master - add binman for rk3288, rk3328, rk3368, rk3399 - added rst documentation for rockchip Changes for v2: - Add few clean target patches - update bl31.elf env handling code, with logging - support puma itb, via BL31 and PMUM0 env - enable BUILD_TARGET for ROCKCHIP_RK3399

Add rockchip image type support. right now the image type marked with rksd, So create image type variable with required image type like rksd or rkspi.

Most of the platforms uses the platform type on their boot stage image naming conventions in makefile like,
u-boot-x86-start16-tpl.bin - x86 start16 TPL bin u-boot-spl-mtk.bin - Mediatek SPL bin
This would help to understand the users to what that particular image belongs to? and less confused.
On that note, suffix platform type rockchip for existing u-boot-tpl.img so now it become u-boot-tpl-rockchip.bin
Also, bin is more conventional way to include it on tools like binman, pad_cat etc in future patches.
Note: usage of platform type doesn't follow consistent order as of now.

Add SPL-alone mkimage tooling support via Makefile for few platforms or boards used in rockchip family.
With this users would get rid of explicitly creating mkimage tool for rockchip rksd or rkspi boot modes.

Most of the platforms uses the platform type and particular boot stage on their image naming conventions in makefile like,
u-boot-sunxi-with-spl.bin - Allwinner U-Boot with SPL u-boot-spl-mtk.bin - Mediatek SPL bin
This would help to understand the users to what that particular image belongs to? and less confused.
On that note, use u-boot-spl-rockchip.bin instead of idbloader.img. idbloader.img is still a proper naming for rockchip external documentation but u-boot preferred spl name would always good choice in upstream tree.
Also, bin is more conventional way to include it on tools like binman, pad_cat etc in future patches.
Note: usage of platform type, boot stage doesn't follow consistent oder as of now.

Add U-Boot specific dtsi file for rk3036 SoC. This would help to add U-Boot specific dts nodes, properties which are common across rk3036.
Right now, the file is empty, will add required changes in future patches.

All rockchip platforms support TPL or SPL-based bootloader in mainline with U-Boot proper as final stage. For each stage we need to burn the image on to flash with respective offsets.
This patch creates a single boot image component using - binman, for arm32 rockchip platforms - pad_cat, for arm64 rockchip platforms.
This would help users to get rid of burning different boot stage images.
The new image called 'u-boot-rockchip.bin' which can burn into flash like:
₹ sudo dd if=u-boot-rockchip.bin of=/dev/sda seek=64
This would support all rockchip platforms, except rk3128 since it doesn't support for SPL yet.

All rockchip platforms support TPL or SPL-based bootloader in mainline with U-Boot proper as final stage. For each stage we need to burn the image on to flash with respective offsets.
This patch creates a single boot image component using
- binman, for arm32 rockchip platforms
- pad_cat, for arm64 rockchip platforms.
This would help users to get rid of burning different boot stage images.
The new image called 'u-boot-rockchip.bin' which can burn into flash like:
₹ sudo dd if=u-boot-rockchip.bin of=/dev/sda seek=64
This would support all rockchip platforms, except rk3128 since it doesn't support for SPL yet.

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.

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.

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?

Yes, I mean so. I think it would be great to have something like the section describing where do the things came from and the layout which is under the hood.
