Concerning the patch in question, is it possible to allow cache for ram on PXA270 somehow before we have a final solution?
I dont mind discussing this further and even using DCache for stack in board_init_f(), but we must make sure nothing gets broken.
If it is possible, I would like to have a configuration option, which allows to use D-Cache as RAM not only on PXA25X, but also on PXA27X. I propose to preserve status-quo for now and only use D-Cache as RAM when it is explicitly configured so.
See above, let's do it properly please. Check the OneNAND SPL config on vpac270 board, will it still work with this enabled?
You mentioned in a separate letter, that config options need documenting. This part is missing in my patch, and I'll fix this, if the above is OK.
Best regards, Marek Vasut
