Testing under U-Boot doesn't tend to find calibration errors. It would be helpful to test under U-Boot by adding support for changing up the DDR frequencies (as done in the NXP test), but that's something for another day.

Re: [PATCH 07/18] mx6memcal: Disable USB GADGET in SPL
Since the proper U-Boot doesn't do anything at the moment, I don't think this hurts much. My usage of mx6memcal generally ends after SPL spits out calibration values, and I suspect the same is true for other users, so Acked-by: Eric Nelson On 5/22/21 5:47 AM, Tom Rini wrote: > As this board does not use CONFIG_OF_CONTROL and the DM_USB migration > deadline has passed, disable USB_GADGET support. > > Cc: Eric Nelson > Cc: Stefano Babic > Signed-off-by: Tom Rini > --- > I realize this removes an important functional part of the board.
