* AVR32: Make SDRAM refresh rate configurableHaavard Skinnemoen2008-02-051-1/+5
| | | | | | | | | | | | | | The existing code assumes the SDRAM row refresh period should always be 15.6 us. This is not always true, and indeed on the ATNGW100, the refresh rate should really be 7.81 us. Add a refresh_period member to struct sdram_info and initialize it properly for both ATSTK1000 and ATNGW100. Out-of-tree boards will panic() until the refresh_period member is updated properly. Big thanks to Gerhard Berghofer for pointing out this issue. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* AVR32: Fix wrong pin setup for USART3Haavard Skinnemoen2007-12-171-1/+1
| | | | | | | | | | | | As reported by Gerhard Berghofer: in "gpio_enable_usart3" the correct pins for USART 3 are PB17 and PB18 instead of PB18 and PB19. which is obviously correct. There's currently no code that uses USART3, but custom boards may run into problems. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* AVR32: Make some AT32AP700x peripherals optionalHaavard Skinnemoen2007-12-171-0/+7
| | | | | | | | | | | Add a chip-features file providing definitions of the form AT32AP700x_CHIP_HAS_<peripheral> to indicate the availability of the given peripheral on the currently selected chip. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* AVR32: Rename at32ap7000 -> at32ap700xHaavard Skinnemoen2007-12-172-0/+0
| | | | | | | | | The SoC-specific code for all the AT32AP700x CPUs is practically identical; the only difference is that some chips have less features than others. By doing this rename, we can add support for the AP7000 derivatives simply by making some features conditional. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* atmel_mci: Show SR when block read failsHaavard Skinnemoen2007-12-171-6/+7
| | | | | | | Show controller status as well as card status when an error occurs during block read. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* atmel_mci: Fix data timeout valueHaavard Skinnemoen2007-08-131-0/+59
| | | | | | | | | Calculate the data timeout based on values from the CSD instead of just using a hardcoded DTOR value. This is a backport of a similar fix in BSP 2.0, with one additional fix: the DTOCYC value is rounded up instead of down. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* AVR32: Include <div64.h> instead of <asm/div64.h>Haavard Skinnemoen2007-08-131-1/+1
| | | | | | | | | | | include/asm-avr32/div64.h was recently moved to include/div64.h, but cpu/at32ap/interrupts.c wasn't properly updated (an earlier version of the patch was merged perhaps?) This patch updates cpu/at32ap/interrupts.c so that the avr32 port compiles again. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* atmel_mci: Use 512 byte blocksize if possibleHaavard Skinnemoen2007-08-132-4/+21
| | | | | | | | | | | | Instead of always using the largest blocksize the card supports, check if it can support smaller block sizes and use 512 bytes if possible. Most cards do support this, and other parts of u-boot seem to have trouble with block sizes different from 512 bytes. Also enable underrun/overrun protection.

| * Atmel MCI driverHaavard Skinnemoen2007-04-143-1/+675
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Driver for the Atmel MCI controller (MMC interface) for AT32AP CPUs. The AT91 ARM-based CPUs use basically the same hardware, so it should be possible to share this driver, but no effort has been made so far. Hardware documentation can be found in the AT32AP7000 data sheet, which can be downloaded from http://www.atmel.com/dyn/products/datasheets.asp?family_id=682 Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

| * AVR32: Relocate u-boot to SDRAMHaavard Skinnemoen2007-04-144-36/+90
| | | | | | | | | | | | | | Relocate the u-boot image into SDRAM like everyone else does. This means that we can handle much larger .data and .bss than we used to. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
| * AVR32: Resource management rewriteHaavard Skinnemoen2007-04-1415-862/+198
| | | | | | | | | | | | | | | | | | | | | | | | | | Rewrite the resource management code (i.e. I/O memory, clock gating, gpio) so it doesn't depend on any global state. This is necessary because this code is heavily used before relocation to RAM, so we can't write to any global variables. As an added bonus, this makes u-boot's memory footprint a bit smaller, although some functionality has been left out; all clocks are enabled all the time, and there's no checking for gpio line conflicts.

| * AVR32: Split start_u_boot into board_init_f and board_init_rHaavard Skinnemoen2007-04-141-1/+1
|/ | | | | | | | | Split the avr32 initialization code into a function to run before relocation, board_init_f and a function to run after relocation, board_init_r. For now, board_init_f simply calls board_init_r at the end. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

* Add AT32AP CPU and AT32AP7000 SoC supportWolfgang Denk2006-10-2419-0/+2287
Patch by Haavard Skinnemoen, 06 Sep 2006 This patch adds support for the AT32AP CPU family and the AT32AP7000 chip, which is the first chip implementing the AVR32 architecture. The AT32AP CPU core is a high-performance implementation featuring a 7-stage pipeline, separate instruction- and data caches, and a MMU. For more information, please see the "AVR32 AP Technical Reference": http://www.atmel.com/dyn/resources/prod_documents/doc32001.pdf In addition to this, the AT32AP7000 chip comes with a large set of integrated peripherals, many of which are shared with the AT91 series of ARM-based microcontrollers from Atmel.
