Hello,
This patch adds support for the Intel D810E2CB desktop board. This patch has to go in after the other two patches I have submitted, it is dependent on them. Hurray, this is the first i810 board running CAR :-)

Build and boot (bootlog attached) tested:

+#define ICH_IO_BASE_ADDR	0x00000500 /* GPIO base address register */
This is duplicated from i82801ax_lpc.c ... Can it go into i82801ax.h and be included here instead? (It's also called GPIO_BASE_ADDRESS elsewhere)

+
+	/* Set the value for GPIO base address register and enable GPIO. */
+	pci_write_config32(dev, 0x58, (ICH_IO_BASE_ADDR | 1));
+	pci_write_config8(dev, 0x5c, 0x10);

0x58 is GPIO_BASE_ICH0_5 in i82801ax.h (should be renamed to GPIO_BASE  I guess)

+	udelay(10);
