[U-Boot-Users] Probelm with 8266ADS board.

[Rune Torgersen]

This is of course a problem with the SDRAM.

Check that CONFIG_PBI is set to 0 (set in top of mpc8266ads.c)
This stets the controller in Bank Based interleave.
I have seen this excact problem when running Page Based access to the
standard 16MB devices.

Page Based is supposed to be faster, and is necessary to use more than 128MB
per chip select.
