* AVR32: Remove useless config option "GENERIC_BUST_SPINLOCK".Robert P. J. Day2007-04-271-3/+0
| | | | | | | | Remove the clearly useless config option GENERIC_BUST_SPINLOCK, which is not used anywhere in the tree. Signed-off-by: Robert P. J. Day <rpjday@mindspring.com> Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* [AVR32] Optimize the TLB miss handlerHaavard Skinnemoen2007-04-271-30/+24
| | | | | | | | | | | Reorder some instructions and change the register usage to reduce the number of pipeline stalls. Also use the bfextu and bfins instructions for bitfield manipulations instead of shifting and masking. This makes gzipping a 80MB file approximately 2% faster.

* [AVR32] Get rid of board_setup_fbmem()Haavard Skinnemoen2007-04-273-36/+5
| | | | | | | | | Since the core setup code takes care of both allocation and reservation of framebuffer memory, there's no need for this board- specific hook anymore. Replace it with two global variables, fbmem_start and fbmem_size, which can be used directly. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* [AVR32] Reserve framebuffer memory in early_parse_fbmem()Haavard Skinnemoen2007-04-271-7/+61
| | | | | | | | | | | | | | With the current strategy of using the bootmem allocator to allocate or reserve framebuffer memory, there's a slight chance that the requested area has been taken by the boot allocator bitmap before we get around to reserving it. By inserting the framebuffer region as a reserved region as early as possible, we improve our chances for success and we make the region visible as a reserved region in dmesg and /proc/iomem without any extra work.

* [AVR32] Simplify early handling of memory regionsHaavard Skinnemoen2007-04-271-263/+232
| | | | | | | | | | | Use struct resource to specify both physical memory regions and reserved regions and push everything into the same framework, including kernel code/data and initrd memory. This allows us to get rid of many special cases in the bootmem initialization and will also make it easier to implement more robust handling of framebuffer memory later.

* [AVR32] Make I/O access macros work with external devicesHaavard Skinnemoen2007-04-271-1/+25
| | | | | | | | | | | | | | | | | | | Fix the I/O access macros so that they work with externally connected devices accessed in little-endian mode over any bus width: * Use a set of macros to define I/O port- and memory operations borrowed from MIPS. * Allow subarchitecture to specify address- and data-mangling * Implement at32ap-specific port mangling (with build-time configurable bus width. Only one bus width at a time supported for now.) * Rewrite iowriteN and friends to use write[bwl] and friends (not the __raw counterparts.) This has been tested using pata_pcmcia to access a CompactFlash card connected to the EBI (16-bit bus width.) Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* [AVR32] Fix NMI handlerHaavard Skinnemoen2007-04-271-3/+25
| | | | | | | | | | | | | Fix a problem with the NMI handler entry code related to the NMI handler sharing some code with the exception handlers. This is not a good idea because the RSR and RAR registers are not the same, and the NMI handler runs with interrupts masked the whole time so there's no need to check for pending work. Open-code the low-level NMI handling logic instead so that the pt_regs layout is actually correct when the higher-level handler is called. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* [AVR32] Clean up exception handling codeHaavard Skinnemoen2007-04-276-393/+357
| | | | | | | | | | | | | | | * Use generic BUG() handling * Remove some useless debug statements * Use a common function _exception() to send signals or oops when an exception can't be handled. This makes sure init doesn't enter an infinite exception loop as well. Borrowed from powerpc. * Add some basic exception tracing support to the page fault code. * Rework dump_stack(), show_regs() and friends and move everything into process.c * Print information about configuration options and chip type when oopsing Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* [AVR32] Clean up cpu identification and add features bitmapHaavard Skinnemoen2007-04-271-20/+44

Also, add a features bitmap to struct avr32_cpuinfo to allow other code to make decisions based upon what the running cpu is actually capable of.

* [AVR32] Put cpu in sleep 0 when idle.Hans-Christian Egtvedt2007-04-272-7/+40

* [AVR32] Change system timer from count-compare to Timer/Counter 0Hans-Christian Egtvedt2007-04-274-73/+313
| | | | | | | | | | | | | | | | | | | | Due to limitation of the count-compare system timer (not able to count when CPU is in sleep), the system timer had to be changed to use a peripheral timer/counter. The old COUNT-COMPARE code is still present in time.c as weak functions. The new timer is added to the architecture directory. This patch sets up TC0 as system timer The new timer has been tested on AT32AP7000/ATSTK1000 at 100 Hz, 250 Hz, 300 Hz and 1000 Hz.

* [PATCH] gpio_direction_output() needs an initial valueDavid Brownell2007-03-161-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | It's been pointed out that output GPIOs should have an initial value, to avoid signal glitching ... among other things, it can be some time before a driver is ready. This patch corrects that oversight, fixing - documentation - platforms supporting the GPIO interface - users of that call (just one for now, others are pending) There's only one user of this call for now since most platforms are still using non-generic GPIO setup code, which in most cases already couples the initial value with its "set output mode" request. Note that most platforms are clear about the hardware letting the output value be set before the pin direction is changed, but the s3c241x docs are vague on that topic ... so those chips might not avoid the glitches.

* [AVR32] show_trace: Only walk valid stack addressesHaavard Skinnemoen2007-03-071-23/+29
| | | | | | | | | | | | Terminate the frame pointer walk if (a) the address is outside the task's kernel stack or (b) if the frame pointer isn't monotonically increasing. Without this fix, show_trace() may enter an infinite loop, walking through random data anywhere in memory. Since any address within the kernel stack is guaranteed to be valid, we may eliminate the __get_user() calls as well. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

* [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.
