The initial PMIC setup for the Allwinner platform is quite board specific, and used to be guarded by reading the .dtb stub *name* from the SPL image in the legacy ATF port. This doesn't scale particularly well, and requires constant maintainance. Instead having the actual .dtb available would be much better, as the PMIC setup requirements could be read from there directly. The only available BL33 for Allwinner platforms so far is U-Boot, and fortunately U-Boot comes with the full featured .dtb, appended to the end of the U-Boot image. Introduce some code that scans the beginning of the BL33 image to look for the load address, which is followed by the image size. Adding those two values together gives us the end of the image and thus the .dtb address. Verify that this heuristic is valid by sanitising some values and checking the DTB magic. Print out the DTB address and the model name, if specified in the root node. Signed-off-by: Andre Przywara <andre.przywara@arm.com> |
