Remove the CPU selection menu and instead let it be selected by the board or daughterboard option. Add daughterboard selection for ATSTK1000 (this was previously determined based on CPU type.) Signed-off-by: NHaavard Skinnemoen <hskinnemoen@atmel.com>

These are derivatives of the AT32AP7000 chip, which means that most of the code stays the same. Rename a few files, functions, definitions and config symbols to reflect that they apply to all AP700x chips, and exclude some platform devices from chips where they aren't present.

Most of these fixes were already submitted for old kernel versions, and were approved, but for some reason they never made it into the releases. Because this is a consolidation of a couple old missed patches, it touches both Kconfigs and documentation texts.

This adds some STK1002-specific config options covering the jumper settings, so the kernel can automatically be configured to include the relevant devices. One of them replaces the previous internal SW2_DEFAULT setting; SPI config is affected by two of the jumpers; and a fourth one switches between LCD and the second Ethernet connector. (There's more that to be done.) Signed-off-by: NDavid Brownell <dbrownell@users.sourceforge.net> Signed-off-by: NHaavard Skinnemoen <hskinnemoen@atmel.com>

This patch enables CPU frequency scaling for AT32AP devices. This will enable the CPU to scale between the speed of the high speed bus and the master clock and thus save some power. The patch also adds a parent to cpu_clk and a cpu_clk_set_rate to enable changing the CPU clock divider in a sane way. The driver does not check if the given rate is 0, thus resulting in a div by 0. I think this check should be go into the clk_set_rate framework, and not here. Tested on AT32AP7000/ATSTK1000. Hardware documentation can be found in the AT32AP7000 datasheet.

* 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: NHaavard Skinnemoen <hskinnemoen@atmel.com>

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.

This adds support for the Atmel AVR32 architecture as well as the AT32AP7000 CPU and the AT32STK1000 development board. AVR32 is a new high-performance 32-bit RISC microprocessor core, designed for cost-sensitive embedded applications, with particular emphasis on low power consumption and high code density. The AVR32 architecture is not binary compatible with earlier 8-bit AVR architectures. The AVR32 architecture, including the instruction set, is described by the AVR32 Architecture Manual, available from http://www.atmel.com/dyn/resources/prod_documents/doc32000.pdf The Atmel AT32AP7000 is the first CPU implementing the AVR32 architecture. It features a 7-stage pipeline, 16KB instruction and data caches and a full Memory Management Unit. It also comes with a large set of integrated peripherals, many of which are shared with the AT91 ARM-based controllers from Atmel. Full data sheet is available from http://www.atmel.com/dyn/resources/prod_documents/doc32003.pdf while the CPU core implementation including caches and MMU is documented by the AVR32 AP Technical Reference, available from http://www.atmel.com/dyn/resources/prod_documents/doc32001.pdf Information about the AT32STK1000 development board can be found at http://www.atmel.com/dyn/products/tools_card.asp?tool_id=3918 including a BSP CD image with an earlier version of this patch, development tools (binaries and source/patches) and a root filesystem image suitable for booting from SD card. Alternatively, there's a preliminary "getting started" guide available at http://avr32linux.org/twiki/bin/view/Main/GettingStarted which provides links to the sources and patches you will need in order to set up a cross-compiling environment for avr32-linux. This patch, as well as the other patches included with the BSP and the toolchain patches, is actively supported by Atmel Corporation.
