This patch adds KS8695 CPU machine support. It is pretty much a standard ARM922T core. This patch inludes the cpu/machine configuration and Makefile changes, the architecture, timer, interrupt and PCI support. diff -Naur linux-2.6.16/arch/arm/Kconfig linux-2.6.16.ks8695/arch/arm/Kconfig --- linux-2.6.16/arch/arm/Kconfig 2006-03-20 15:53:29.000000000 +1000 +++ linux-2.6.16.ks8695/arch/arm/Kconfig 2006-03-22 09:57:18.000000000 +1000 @@ -141,6 +141,13 @@ help Support for Intel's IXP2400/2800 (XScale) family of processors. +config ARCH_KS8695 + bool "Kendin-Micrel KS8695" + help + The Kendin-Micrel KS8695 "Centaur" family is an ARM920 based + System-On-Chip device.
