2015-10-01clocksource: cosmetic: Drop OF 'dependency' from symbolsMarc Zyngier1-1/+1
Seeing the 'of' characters in a symbol that is being called from ACPI seems to freak out people. So let's do a bit of pointless renaming so that these folks do feel at home.

As of commit 9a1091ef0017c40a ("irqchip: gic: Support hierarchy irq domain."), Marzen legacy hangs during boot with: Image Name: 'Linux-3.19.0-rc4' Image Type: ARM Linux Kernel Image (uncompressed) Data Size: 3445880 Bytes = 3.3 MiB Load Address: 60008000 Entry Point: 60008000 Verifying Checksum ... OK Loading Kernel Image ... OK OK Starting kernel ... Enabling DEBUG_LL does not seem to change the situation, however this patch by itself fixes this issue and re-enables normal boot. This issue happens because the IRQ numbers of the GIC are now virtual, and no longer match the hardcoded hardware IRQ numbers in the platform board code. To fix this, instantiate the GIC from platform board code when compiling a legacy kernel, like is done for the sh73a0, r8a7740 and r8a7778 legacy code. Follows same style as the r8a7740 legacy GIC fix by Geert Uytterhoeven, thanks to him for the initial work.

2014-11-17ARM: shmobile: Add early debugging support using SCIF(A)Geert Uytterhoeven1-0/+1
Add serial port debug macros for the SCIF(A) serial ports. This includes all supported shmobile SoCs, except for EMEV2. The configuration logic (both Kconfig and #ifdef) is more complicated than one would expect, for several reasons: 1. Not all SoCs have the same serial devices, and they're not always at the same addresses. 2. There are two different types: SCIF and SCIFA. Fortunately they can easily be distinguished by physical address. 3. Not all boards use the same serial port for the console. The defaults correspond to the boards that are supported in mainline. If you want to use a different serial port, just change the value of CONFIG_DEBUG_UART_PHYS, and the rest will auto-adapt. 4. debug_ll_io_init() maps the SCIF(A) registers to a fixed virtual address. 0xfdxxxxxx was chosen, as it should lie below VMALLOC_END = 0xff000000, and must not conflict with the 2 MiB reserved region at PCI_IO_VIRT_BASE = 0xfee00000. - On SoCs not using the legacy machine_desc.map_io(), debug_ll_io_init() is called by the ARM core code. - On SoCs using the legacy machine_desc.map_io(), debug_ll_io_init() must be called explicitly. Calls are added for r8a7740, r8a7779, sh7372, and sh73a0. This was derived from the r8a7790 version by Laurent Pinchart.

2014-06-06Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm into nextLinus Torvalds1-2/+2
Pull ARM updates from Russell King: - Major clean-up of the L2 cache support code. The existing mess was becoming rather unmaintainable through all the additions that others have done over time. This turns it into a much nicer structure, and implements a few performance improvements as well. - Clean up some of the CP15 control register tweaks for alignment support, moving some code and data into alignment.c - DMA properties for ARM, from Santosh and reviewed by DT people. This adds DT properties to specify bus translations we can't discover automatically, and to indicate whether devices are coherent. - Hibernation support for ARM - Make ftrace work with read-only text in modules - add suspend support for PJ4B CPUs - rework interrupt masking for undefined instruction handling, which allows us to enable interrupts earlier in the handling of these exceptions. - support for big endian page tables - fix stacktrace support to exclude stacktrace functions from the trace, and add save_stack_trace_regs() implementation so that kprobes can record stack traces. - Add support for the Cortex-A17 CPU. - Remove last vestiges of ARM710 support. - Removal of ARM "meminfo" structure, finally converting us solely to memblock to handle the early memory initialisation. * 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: (142 commits) ARM: ensure C page table setup code follows assembly code (part II) ARM: ensure C page table setup code follows assembly code ARM: consolidate last remaining open-coded alignment trap enable ARM: remove global cr_no_alignment ARM: remove CPU_CP15 conditional from alignment.c ARM: remove unused adjust_cr() function ARM: move "noalign" command line option to alignment.c ARM: provide common method to clear bits in CPU control register ARM: 8025/1: Get rid of meminfo ARM: 8060/1: mm: allow sub-architectures to override PCI I/O memory type ARM: 8066/1: correction for ARM patch 8031/2 ARM: 8049/1: ftrace/add save_stack_trace_regs() implementation ARM: 8065/1: remove last use of CONFIG_CPU_ARM710 ARM: 8062/1: Modify ldrt fixup handler to re-execute the userspace instruction ARM: 8047/1: rwsem: use asm-generic rwsem implementation ARM: l2c: trial at enabling some Cortex-A9 optimisations ARM: l2c: add warnings for stuff modifying aux_ctrl register values ARM: l2c: print a warning with L2C-310 caches if the cache size is modified ARM: l2c: remove old .set_debug method ARM: l2c: kill L2X0_AUX_CTRL_MASK before anyone else makes use of this ...

The cache size should already be present in the L2 cache auxiliary control register: it is part of the integration process to configure the hardware IP. Most platforms get this right, yet still many cargo-cult program, and assume that they always need specifying to the L2 cache code. Remove them so we can find out which really need this.

2013-08-30ARM: shmobile: r8a7779: Update early timer initialisation orderSimon Horman1-1/+1
a894fcc2d01a89e6fe3da0845a4d80a5312e1124 ("ARM: smp_twd: Divorce smp_twd from local timer API") altered twd_local_timer_common_register() so that it may make use of late_timer_init. This is problematic on marzen with Magnus's recent patch "ARM: shmobile: marzen: Switch to DT_MACHINE_START" which switches marzen around to enable USE_OF and thus shmobile_timer_init(), which is registered as late_time_init by shmobile_earlytimer_init() stops being a no-op. As a work-around I have updated r8a7779_earlytimer_init() so that shmobile_earlytimer_init() is called after r8a7779_register_twd(). Or in other words, the shmobile_earlytimer_init() setting of late_time_init overwrites that of twd_local_timer_common_register().
