Only 1GB of ram and no PCIe (so no USBs). FYI I've been working on getting a workable configuration for arm32, short = of creating a new config altogether: https://www.mail-archive.com/linuxppc-dev@lists.ozlabs.org/msg163770.html That said, if you insist on booting with bcm2835_defconfig, I have no probl= em with the patch.
