I understand this is just a rename, but I want to ask anyway: if flash
type and RAM size are the only differences, then why do we need two
separate board definitions here?

Would not even the same U-Boot binary image run on both boards?  These
flashes are CFI compatible, so the CFI driver would work on both, and
RAM size autodetection has been available in U-Boot forever.

In worst case, we coul differentiate boards by an additional #define,
which means we only need a single line entry in boards.cfg.

Why do we need to support two board entries?

Best regards,

Wolfgang Denk
