From 7c90f3b2b498531a267b0e85c4f634f65d76eba8 Mon Sep 17 00:00:00 2001 From: florian Date: Tue, 19 Jun 2012 14:48:56 +0000 Subject: [mcs814x] add Moschip MSC814x support This target currently only supports Moschip's MCS8140 SoC, but support for other chips in the same family (MCS8142, MCS8144) will be easy to add. Target support is entirely using Device Tree for probing peripherals. Drivers support include: - PCI - USB 1 & 2 - watchdog - random number generator - UART - timer - internal Ethernet PHY - Ethernet MAC core Support for the following boards is included using Device Tree - Devolo dLAN USB Extender - Tigal RBT-832 git-svn-id: svn://svn.openwrt.org/openwrt/trunk@32462 3c298f89-4303-0410-b956-a3cf2f4a3e73 --- .../files-3.3/arch/arm/mach-mcs814x/include/mach/cpu.h | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) create mode 100644 target/linux/mcs814x/files-3.3/arch/arm/mach-mcs814x/include/mach/cpu.h (limited to 'target/linux/mcs814x/files-3.3/arch/arm/mach-mcs814x/include/mach/cpu.h') diff --git a/target/linux/mcs814x/files-3.3/arch/arm/mach-mcs814x/include/mach/cpu.h b/target/linux/mcs814x/files-3.3/arch/arm/mach-mcs814x/include/mach/cpu.h new file mode 100644 index 000000000..1ef3c4a03 --- /dev/null +++ b/target/linux/mcs814x/files-3.3/arch/arm/mach-mcs814x/include/mach/cpu.h @@ -0,0 +1,16 @@ +#ifndef __ASM_ARCH_CPU_H__ +#define __ASM_ARCH_CPU_H__ + +#include + +#define MCS8140_ID 0x41069260 /* ARM926EJ-S */ +#define MCS814X_MASK 0xff0ffff0 + +#ifdef CONFIG_MCS8140 +/* Moschip MCS8140 is based on an ARM926EJ-S core */ +#define soc_is_mcs8140() ((read_cpuid_id() & MCS814X_MASK) == MCS8140_ID) +#else +#define soc_is_mcs8140() (0) +#endif /* !CONFIG_MCS8140 */ + +#endif /* __ASM_ARCH_CPU_H__ */ -- cgit v1.2.3
