Hello list,
inside the automatic U-Boot patch tracking system a new ticket [DNX#2006040142001187] was created:

Careful. ML403 reference design (as-is) is not using the Xilinx option of using side-by-side data access (32-bit fetch out of a single 16-bit flash), so XIP (execution in place) is evidently NOT supported in ML403. However, I had a new bit file built with side-by-side data access enabled, but haven't yet execute out of flash (no need because ML403 has a big memory.) But it correctly fetches 32-bit now. Ping me in a week on my progress with XIP and flash.
Hmm, why do you need that? The ML403 has two flash chips and with that allows 32 bit wide accesses. That allows you to access the whole flash space and should give you much better performance than executing out of a 16 bit wide flash.
