* [PATCH] add CONFIG_GENERIC_GPIODavid Brownell2007-03-051-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | Most drivers using GPIOs already know they are running on a system that supports the generic GPIO calls, because of other platform dependencies. But the generic GPIO-based LED and input button drivers can't know that. So this patch adds a Kconfig hook, GENERIC_GPIO, to mark the platforms where <asm/gpio.h> will do the right thing. Currently that's a bunch of ARMs, and AVR32; more are on the way. It also fixes a dependency bug for the gpio button input driver; it was wrong to start with, now it covers all platforms with GENERIC_GPIO.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This facility provides three entry points: ilog2() Log base 2 of unsigned long ilog2_u32() Log base 2 of u32 ilog2_u64() Log base 2 of u64 These facilities can either be used inside functions on dynamic data: int do_something(long q) { ...; y = ilog2(x) ...; } Or can be used to statically initialise global variables with constant values: unsigned n = ilog2(27); When performing static initialisation, the compiler will report "error: initializer element is not constant" if asked to take a log of zero or of something not reducible to a constant. They treat negative numbers as unsigned. When not dealing with a constant, they fall back to using fls() which permits them to use arch-specific log calculation instructions - such as BSR on x86/x86_64 or SCAN on FRV - if available.

* [PATCH] avr32: fixup kprobes preemption handlingPaul Mundt2006-12-071-0/+1
| | | | | | | | | | | | | | | | | While working on SH kprobes, I noticed that avr32 got the preemption handling wrong in the no probe case. The idea is that upon entry of kprobe_handler() preemption is disabled outright across the life of the kprobe, only to be re-enabled in post_kprobe_handler(). However, in the event that the probe is never activated, there's never any chance of hitting the post probe handler, which allows for the current avr32 implementation to disable preemption indefinitely, as it's currently missing a re-enable when no probe is activated.

In order to run without a boot loader, we need to create a zImage stub or have the debugger initialize the SDRAM for us (for really low-level debugging) Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* [PATCH] vmlinux.lds: consolidate initcall sectionsAndrew Morton2006-10-281-7/+1
| | | | | | | | | | | | | | Add a vmlinux.lds.h helper macro for defining the eight-level initcall table, teach all the architectures to use it. This is a prerequisite for a patch which performs initcall synchronisation for multithreaded-probing.

* [PATCH] AVR32: Update defconfigHaavard Skinnemoen2006-10-261-94/+159
| | | | | | | | | Sync atstk1002_defconfig with latest git, turn off non-existent drivers and enable a few more userspace-visible options like SysV IPC and inotify support. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] AVR32: Use __raw MMIO access for internal peripheralsHaavard Skinnemoen2006-10-264-8/+14
| | | | | | | | | | | | | | | The read[bwl] and write[bwl] functions are meant for accessing PCI devices. How this is achieved on AVR32 is unknown, as there are no systems with a PCI bridge available yet. On-chip peripheral access, however, should not depend on how we end up implementing PCI access, so using __raw_read[bwl]/__raw_write[bwl] is the right thing to do for on-chip peripherals. This patch converts the drivers for the static memory controller, interrupt controller, PIO controller and system manager to use __raw MMIO access.
