Hi all, This series aims to add support for the Radxa ROCK3 Model A single board computer featuring the Rockchip RK3568 SoC. The first two patches mock the dts sync from the Linux kernel and introduce the device tree for the board (will appear in Linux v5.19-rc1). These patches can be dropped of course and are added only for convenience. There are a few open issues that are somewhat shared by all RK356x boards: - The RAM size is defined in the device tree and limited to 2 GB. This is correct for the 2 GB version lying around on my desk, but it should be noted that there are also 4 GB and 8 GB versions of this board available. - The eMMC controller seems to require the "no-sd" property in the device tree, which is not present in the mainline version. The quick fix is to provide this property in the barebox dts. - RFC: The "rk3568_start" method in the low-level board code seems to be shared by all RK356x boards. Can it be refactored and made non-static? If yes, what would be a reasonable location for the new function? - Of course the IO domain bits are board specific. In the long run they should be replaced anyway by a proper iodomain driver. For the time being I believe they could remain in the ENTRY_FUNCTION. Apart from these issues (which are not exactly critical) barebox works just fine on this neat little board. Looking forward to your comments!
