Mon May 20 23:26:00 CEST 2013
LP-8x4x is a programmable automation controller by ICP DAS. It is
shipped with outdated U-Boot v1.3.0
This patch adds enough supports to boot the board:
- 128M of 128M SDRAM
- 32M of 48M NOR Flash memory
- 1 of 4 Serial consoles (PXA FFUART)
- 2 of 2 Ethernet controllers (DM9000)

Changes for v2:
- use get_ram_size(...) to init ram size
- fix defines
- fix formatting
- fix board GPIO settings
- initialize eth1 MAC for kernel
- use proper CONFIG_MACH_TYPE to init r1 in kernel call
- use proper image format in default boot cmd
