As discussed this series reverts the HAFDBS changes that caused an issue on AC5/AC5X. I think there are some improvements that can be made to the initial memory map for the AC5/AC5X but so far nothing I've found makes it compatible with the HAFDBS changes.
Would you mind briefly explaining what those issues are and/or point me to the discussion where it was decided to revert these patches?
The feature is quite useful for users of CONFIG_CMO_BY_VA_ONLY, to speed up the boot sequence: instead of reverting these patches altogether, would a reasonable alternative be to put them behind a build option?
Also, could you confirm that the "initial memory map" you are referring to above only describes actual memory as, IIRC, some boards were using mappings **much** larger than their DRAM address space?
The most details are in this thread: https://lore.kernel.org/u-boot/CAFOYHZC_Dveax85n0fLr5BFyZcLqsvUssn=J0oHyvN75... with some follow-up in: https://lore.kernel.org/u-boot/CAFOYHZB7jJWwD24oWzx6u55w2whHYjK56f=QyN0LWU4Z...
