rockchip: mkimage: Add support for RK3506

2026-03-10T16:07:03+00:00

Add support for generating Rockchip Boot Image for RK3506.

The RK3506 has 48 KiB SRAM and 4 KiB is reserved for BootROM.

rockchip: mkimage: Re-sort the spl_infos list alphanumerically

2026-03-10T16:07:02+00:00

The first RK35xx SoC was initially appended to the end of the otherwise
alphanumerically sorted spl_infos list, possible because it was using a
new header structure.

Re-sort the spl_infos list to keep it alphanumerically ordered based
on imagename.

rockchip: mkimage: enhance comments for v1 header

2025-12-13T16:02:10+00:00

Improve the image header documentation for v1 header:

- specify this applies to all MMC, not only SD cards,
- specify the offset for SPI flashes,
- specify the key used for RC4 encoding,
- specify what "init" refers to, especially since some configs enable
  TPL,
- specify what "init_boot_size" refers to, especially since some configs
  enable TPL,
- specify the size of a block,
- add documentation for init_size and init_boot_size,

Note that the offset on the storage medium isn't necessarily 32KiB (64
blocks) for MMC or 0 for SPI flashes, it's just the first offset the
BootROM checks. Barebox[1] lists a few options, though those are
applicable to RK35xx which use the v2 header, so not guaranteed they can
be shared. On RK3399, the binary can at least be stored at offset 0 and
32KiB on SPI flashes.

rockchip: mkimage: fix mkimage -l for header v1

2024-06-14T09:07:59+00:00

There are two paths to reach this function, either through mkimage -l or
through dumpimage -l. The latter passes a NULL imagename while the
former passes an empty string. Therefore, let's make both tools behave
the same by handling the empty string the same way as for NULL.

Without this, the only way to get some information out of mkimage -l is
to provide "-n rk3399" for example, which isn't documented in the usage
of the tool.

rockchip: mkimage: Update init size limit for RK3568

2023-02-28T10:07:26+00:00

The current init size limit of 76KiB is too big to fit in the 64KiB SRAM
on RK3568, sync init size limit from vendor u-boot to fix this.

Set init size limit to 60KiB (-16KiB) for RK3568.
