[U-Boot] DRAM initialization hangs on MX28EVK rev. D

[Adrien Decostre]

Hello Fabio,

Thanks a lot for your quick answer.
If I correctly understand the board/freescale/mx28evk/README file, only
boot up from SD card or flash is supported. It is not possible to boot
uboot via USB (and by example the sbloader tool)?

Best regards

Adrien
