* ARM / mach-shmobile: r8a7779 SMP TWD boot regression fixMagnus Damm2012-05-121-0/+4
| | | | | | | | | | | | | | | | | | | Fix SMP TWD boot regression on r8a7779 based platforms caused by: 4200b16 ARM: shmobile: convert to twd_local_timer_register() interface After the merge of the above commit it has been impossible to boot r8a7779 based SoCs with SMP enabled and CONFIG_HAVE_ARM_TWD=y. The kernel crashes at smp_init_cpus() timing which is before the console has been initialized, so to the user this looks like a kernel lock up without any particular error message. This patch fixes the regression on r8a7779 by moving the TWD registration code from smp_init_cpus() to sys_timer->init() time.

This got a fair number of conflicts with the <asm/system.h> split, but also with some other sparse-irq and header file include cleanups. They all looked pretty trivial, though. * 'for-linus' of git://git.linaro.org/people/rmk/linux-arm: (59 commits) ARM: fix Kconfig warning for HAVE_BPF_JIT ARM: 7361/1: provide XIP_VIRT_ADDR for no-MMU builds ARM: 7349/1: integrator: convert to sparse irqs ARM: 7259/3: net: JIT compiler for packet filters ARM: 7334/1: add jump label support ARM: 7333/2: jump label: detect %c support for ARM ARM: 7338/1: add support for early console output via semihosting ARM: use set_current_blocked() and block_sigmask() ARM: exec: remove redundant set_fs(USER_DS) ARM: 7332/1: extract out code patch function from kprobes ARM: 7331/1: extract out insn generation code from ftrace ARM: 7330/1: ftrace: use canonical Thumb-2 wide instruction format ARM: 7351/1: ftrace: remove useless memory checks ARM: 7316/1: kexec: EOI active and mask all interrupts in kexec crash path ARM: Versatile Express: add NO_IOPORT ARM: get rid of asm/irq.h in asm/prom.h ARM: 7319/1: Print debug info for SIGBUS in user faults ARM: 7318/1: gic: refactor irq_start assignment ARM: 7317/1: irq: avoid NULL check in for_each_irq_desc loop ARM: 7315/1: perf: add support for the Cortex-A7 PMU ...
| * ARM: shmobile: remove NR_IRQSRob Herring2012-01-261-0/+1
| | | | | | | | | | | | | | | | Remove NR_IRQS and explicitly include mach/irqs.h as needed. shmobile properly allocates irq_descs for each irqchip, so setting .nr_irqs for each machine is not needed. Signed-off-by: Rob Herring <rob.herring@calxeda.com>
* | ARM: shmobile: remove additional __io() macro useArnd Bergmann2012-03-141-1/+1
| | | | | | | | | | | | | | | | | | setup-r8a7779.c has grown a new user of the __io() macro. Rob Herring's PIO cleanup series already gets rid of all other uses in shmobile, so we should ensure that this one gets removed as well.

* | ARM: mach-shmobile: r8a7779 and Marzen timer reworkMagnus Damm2012-03-121-0/+10
| | | | | | | | | | | | | | | | | | | | Move the SoC specific timer code from Marzen board code to r8a7779 setup code. This makes is possible to share the SoC specific timer code across boards and it also removes the need for a board specific timer structure.

* ARM: mach-shmobile: r8a7779 power domain support V2Magnus Damm2012-01-101-0/+8
| | | | | | | | | | | | | | Add power domain control support for the r8a7779 SoC V2. This adds support for 4 power domains for I/O Devices together with code that can be used for CPU cores as well. The only out of the ordinary experience is the need for ioremap() of SYSC registers. Because of that we need to execute some init function before setting up the domains.

* ARM: mach-shmobile: r8a7779 and Marzen base support V2Magnus Damm2012-01-091-0/+231
Initial support for the r8a7779 SoC and the Marzen board (V2). Only SCIF ports and the TMU are supported at this point. To keep things simple only entity-mapped virt-to-phys mappings are supported. This forces drivers and other SoC glue code to make use of ioremap(). We cannot support early serial console due to virtual address space collisions with the ARM kernel.
