Hi
I just found that the 'next' branch you mentioned have problem to boot up.
I test it in p1022ds and p1010rdb boards and the result are both the same.
Note that for p1022ds I use "make p1022ds.dtb" to make the dtb file(36bit) with 36bit-uboot.
And for p1010rdb I use all 32bit image.
The problem list below:
scsi0 : sata_fsl
ata1: SATA max UDMA/133 irq 74
fsl-sata fffe19000.sata: Sata FSL Platform/CSB Driver init
scsi1 : sata_fsl
ata2: SATA max UDMA/133 irq 41
Fixed MDIO Bus: probed

Do you or anyone else have any idea about this?
Thanks.
