New Revision: 745
Modified:
trunk/board_enable.c
Log:
Board enable for ASUS P5ND2-SLI Deluxe.
This patch reorganises the board_ga_k8n_sli to create
nvidia_mcp_gpio_raise, a more general routine to set these bits.
Without docs, i can only assume that these memory area are gpio
lines.
Then it becomes easy to add support for this nForce4 SLI board.
