I see you already addressed a number of issues I mentioned in my previous review of this patch.

Why do we see hardcoded values here and not the data from the CFI driver's auto-sizing? I assume both flash banks are maped into one big contiguous array of NOR flash, right? Then there should be just a single test for "< base || >(base+size)" here, using the total size of the combined flash banks. > printf("bmp addr %lx is not a valid flash address\n", h_addr); > return 0; And why would it be necessary that the BMP resides in NOR flash in the first place? Why cannot - for example - a "preboot" command be used to read it from SDCard into RAM?

If you want to toggle between "small" and "big" configurations, then please use a single #define which is either set or not set. I don't see why this is needed at all. Does not U-Boot auto-detect the RAM size, so you can auto-adjust all code where needed?
