[ARM] 3948/1: AT91: Initial support for AT91SAM9261 and AT91SAM9260 This patch adds the initial support for the newer Atmel AT91SAM9261 and AT91SAM9260 processors. The code is based on, and makes use of, the existing AT91RM9200 support. Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

/*
[ARM] 4124/1: Rename mach-at91rm9200 and arch-at91rm9200 directories Now that Linux includes support for the Atmel AT91SAM9260 and AT91SAM9261 processors in addition to the original Atmel AT91RM9200 (with support for more AT91 processors pending), the "mach-at91rm9200" and "arch-at91rm9200" directories should be renamed to indicate their more generic nature. The following git commands should be run BEFORE applying this patch: git-mv arch/arm/mach-at91rm9200 arch/arm/mach-at91 git-mv include/asm-arm/arch-at91rm9200 include/asm-arm/arch-at91 Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

at91: use structure to store the current soc instead of reading the registers everytime the current implementation respect the following constrain: - allow 1 to n soc to be enabled - allow to have a virtual cpu type and subtype - always detect the cpu type and subtype and report it - detect if the soc support is enabled - prepare for sysfs export support - drop soc specific code via compiler when the soc not enabled (via cpu_is_xxx) Today if we read the exid we will have the same value for 9g35 and 9m11 and we will need to check the cidr too with the new implementation we just need to check the soc subtype this will also allow to have specific virtual subtype for rm9200 which the board will have to specify via at91rm9200_set_type(int) as we have no way to detect it. this implementation is inspired by the SH cpu detection support Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Cc: Nicolas Ferre <nicolas.ferre@atmel.com> Cc: Patrice Vilchez <patrice.vilchez@atmel.com>

ARM: at91: don't use <mach/timex.h> The platform specific <mach/timex.h> will be removed in a later patch. So move its only still used symbol to a different header specific for the only machine still using it. Also add a few explicit includes of <mach/hardware.h> that are implicitly available through <mach/timex.h>.
