MX3: Add basic support for LogicPD i.MX31 LiteKit
This patch adds basic support for i.MX31 LiteKit by LogicPD. With printascii() in kernel/printk.c, it boots right into the rootfs-panic. Note: This is a modified version of Daniel's patch to fit into this patch stack. > On 09.06.2008, at 17:26, Russell King - ARM Linux wrote: > > > I would much prefer it if board specific includes were included by the > > code which needs them rather than in asm/arch/hardware.h.
