Here and else where in the r5 file: why switch from pre-ram to bootph-all ? dont we need these prior to ddr initialization?
Due to the change in how booth-pre-ram works [0], bootph-pre-ram alone no longer works. U-boot docs Pre-Relocation Support section says some-ram can be used for u-boot prior to reloc, but not spl. So like Massimo mentioned in the linked discussion, some-ram + pre-ram can work, as well as -all. Outside of affecting the TPL phase, I'm not sure I know of a difference in regards to how it affects pre-ddr.
