2008-07-15atmel-mci: Driver for Atmel on-chip MMC controllersHaavard Skinnemoen
This is a driver for the MMC controller on the AP7000 chips from Atmel. It should in theory work on AT91 systems too with some tweaking, but since the DMA interface is quite different, it's not entirely clear if it's worth merging this with the at91_mci driver. This driver has been around for a while in BSPs and kernel sources provided by Atmel, but this particular version uses the generic DMA Engine framework (with the slave extensions) instead of an avr32-only DMA controller framework. This driver can also use PIO transfers when no DMA channels are available, and for transfers where using DMA may be difficult or impractical for some reason (e.g. the DMA setup overhead is usually not worth it for very short transfers, and badly aligned buffers or lengths are difficult to handle.) Currently, the driver only support PIO transfers. DMA support has been split out to a separate patch to hopefully make it easier to review. The driver has been tested using mmc-block and ext3fs on several SD, SDHC and MMC+ cards. Reads and writes work fine, with read transfer rates up to 3.5 MiB/s on fast cards with debugging disabled. The driver has also been tested using the mmc_test module on the same cards. All tests except 7, 9, 15 and 17 succeed. The first two are unsupported by all the cards I have, so I don't know if the driver handles this correctly. The last two fail because the hardware flags a Data CRC Error instead of a Data Timeout error. I'm not sure how to deal with that. Documentation for this controller can be found in many data sheets from Atmel, including the AT32AP7000 data sheet which can be found here: http://www.atmel.com/dyn/products/datasheets.asp?family_id=682 Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2008-06-27avr32: improve NGW100 I2C/PMBus setupDavid Brownell
Basic I2C initialization for the NGW100 board: - Provide empty i2c device table. Daughtercards may add devices, and the ATtiny24 could do stuff too. - Set up EXTINT(3) so the ATtiny24 can interrupt the AP7000.

2008-06-27avr32: Add pin configuration choice to LCDC peripheralHans-Christian Egtvedt
This patch lets the board code choose which pin out to use for the LCD interface. On AT32AP7000 the LCDC is wired to two sets of pins, which lets the user choose between dual ethernet and 32-bit EBI. For the ATNGW100 board it is vital to have the choice to select the alternative pinout since this pinout is routed to the external headers. Update ATSTK1002 and ATSTK1004 to use the new interface.

2008-06-27avr32: Allow board to define oscillator ratesAlex
On our custom board we have other oscillator rates than on atngw100 and atstk100x. Currently these rates are hardcoded in arch/avr32/mach-at32ap/at32ap700x.c.

2008-06-07avr32: Add support for ATSTK1006Håvard Skinnemoen
The ATSTK1006 is basically an upgraded version of ATSTK1002 with 128 MiB SDRAM and 256 MiB NAND flash on board. Otherwise, the board is very similar to the ATSTK1002, so it uses the same board support file.

2008-01-25[AVR32] Kconfig: Choose daughterboard instead of CPUHaavard Skinnemoen
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: Haavard Skinnemoen <hskinnemoen@atmel.com>

2008-01-25[AVR32] Add support for AT32AP7001 and AT32AP7002Haavard Skinnemoen
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.

2007-10-11[AVR32] ngw100 i2c-gpio tweaksDavid Brownell
Make the NGW100 bitbang i2c use open drain signaling. Also, speed it up, so it's closer to 100 kHz ... the code paths seem to be long enough that the udelay isn't dominating bit times. The peak bit rate I observed was around 125 kHz, but that's with large delays (usually before ACK/NAK) which hold the overall rate down to around 80 kHz (call it 100 usec/byte on average).

2007-07-18[AVR32] Initialize phy_mask for both macb devicesHaavard Skinnemoen
The STK1000 uses pullups on the MDIO lines to the PHY, but they are too weak. This causes the PHY layer to detect PHYs on all possible MII addresses. Mask out all but the correct address to prevent this from happening. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

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.

2007-04-27[AVR32] Get rid of board_setup_fbmem()Haavard Skinnemoen
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.

2007-02-09[AVR32] Add PIOE device and reserve SDRAM pinsHaavard Skinnemoen
The PIOE device was left out before because it muxes SDRAM pins (and is therefore a bit dangerous to mess with) and because no existing drivers had any use for it. It is needed for CompactFlash, however, and now that we have a way to protect the SDRAM pins, it can be safely added. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-02-09[AVR32] fix serial port setup on ATSTK1000David Brownell
Fixes to USART setup on the stk-1000 ... don't configure USART 2, since its TXD/RXD are used for INT-A and INT-B buttons; and configure USART 0 (for IRDA, and with corrected IRQ) iff SW2 has a non-default setting.

2006-12-08[AVR32] Remove mii_phy_addr and eth_addr from eth_platform_dataHaavard Skinnemoen
The macb driver will probe for the PHY chip and read the mac address from the MACB registers, so we don't need them in eth_platform_data anymore. Since u-boot doesn't currently initialize the MACB registers with the mac addresses, the tag parsing code is kept but instead of sticking the information into eth_platform_data, it uses it to initialize the MACB registers (in case the boot loader didn't do it.) This code should be unnecessary at some point in the future. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2006-12-08[AVR32] Move ethernet tag parsing to board-specific codeHaavard Skinnemoen
By moving the ethernet tag parsing to the board-specific code we avoid the issue of figuring out which device we're supposed to attach the information to. The board specific code knows this because it's where the actual devices are instantiated. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2006-11-06AVR32: Get rid of board_early_initHaavard Skinnemoen
board_early_init() is left over from some early prototyping work where we had to initialize the SDRAM controller ourselves. This depends on the kernel being loaded into static RAM, which just isn't possible on any commercially available products today. 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>
2006-10-04[PATCH] AVR32: Allow renumbering of serial devicesHaavard Skinnemoen
Allow the board to remap actual USART peripheral devices to serial devices by calling at32_map_usart(hw_id, serial_line). This ensures that even though ATSTK1002 uses USART1 as the first serial port, it will still have a ttyS0 device. This also adds a board-specific early setup hook and moves the at32_setup_serial_console() call there from the platform code.

2006-09-26[PATCH] avr32 architectureHaavard Skinnemoen
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.
