2012-07-02ARM: at91: sparse irq supportLudovic Desroches1-0/+1
Enable sparse irq support for multisoc image. It involves to add the NR_IRQS_LEGACY offset to static SoC irq number definitions since NR_IRQS_LEGACY irq descs are allocated before AIC requests irq descs allocation. Move NR_AIC_IRQS macro to a more appropiate place with the purpose to remove mach/irqs.h later.

2012-04-17ARM: at91: drop at91_set_serial_consoleJean-Christophe PLAGNIOL-VILLARD1-12/+0
at91_set_serial_console is used to define the default console of linux. This is already manage by the cmdline. And if the boot loader can not be modified you can still set it by enabling the CONFIG_CMDLINE_EXTEND option. And then the command-line arguments provided by the boot loader will be appended to the default kernel command string.

2012-03-28Merge tag 'split-asm_system_h-for-linus-20120328' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_systemLinus Torvalds1-0/+1
Pull "Disintegrate and delete asm/system.h" from David Howells: "Here are a bunch of patches to disintegrate asm/system.h into a set of separate bits to relieve the problem of circular inclusion dependencies. I've built all the working defconfigs from all the arches that I can and made sure that they don't break. The reason for these patches is that I recently encountered a circular dependency problem that came about when I produced some patches to optimise get_order() by rewriting it to use ilog2(). This uses bitops - and on the SH arch asm/bitops.h drags in asm-generic/get_order.h by a circuituous route involving asm/system.h. The main difficulty seems to be asm/system.h. It holds a number of low level bits with no/few dependencies that are commonly used (eg. memory barriers) and a number of bits with more dependencies that aren't used in many places (eg. switch_to()). These patches break asm/system.h up into the following core pieces: (1) asm/barrier.h Move memory barriers here. This already done for MIPS and Alpha. (2) asm/switch_to.h Move switch_to() and related stuff here. (3) asm/exec.h Move arch_align_stack() here. Other process execution related bits could perhaps go here from asm/processor.h. (4) asm/cmpxchg.h Move xchg() and cmpxchg() here as they're full word atomic ops and frequently used by atomic_xchg() and atomic_cmpxchg(). (5) asm/bug.h Move die() and related bits. (6) asm/auxvec.h Move AT_VECTOR_SIZE_ARCH here. Other arch headers are created as needed on a per-arch basis." Fixed up some conflicts from other header file cleanups and moving code around that has happened in the meantime, so David's testing is somewhat weakened by that. We'll find out anything that got broken and fix it.. * tag 'split-asm_system_h-for-linus-20120328' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system: (38 commits) Delete all instances of asm/system.h Remove all #inclusions of asm/system.h Add #includes needed to permit the removal of asm/system.h Move all declarations of free_initmem() to linux/mm.h Disintegrate asm/system.h for OpenRISC Split arch_align_stack() out from asm-generic/system.h Split the switch_to() wrapper out of asm-generic/system.h Move the asm-generic/system.h xchg() implementation to asm-generic/cmpxchg.h Create asm-generic/barrier.h Make asm-generic/cmpxchg.h #include asm-generic/cmpxchg-local.h Disintegrate asm/system.h for Xtensa Disintegrate asm/system.h for Unicore32 [based on ver #3, changed by gxt] Disintegrate asm/system.h for Tile Disintegrate asm/system.h for Sparc Disintegrate asm/system.h for SH Disintegrate asm/system.h for Score Disintegrate asm/system.h for S390 Disintegrate asm/system.h for PowerPC Disintegrate asm/system.h for PA-RISC Disintegrate asm/system.h for MN10300 ...

2011-07-28at91: use structure to store the current socJean-Christophe PLAGNIOL-VILLARD1-5/+4
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>
