* | avr32: Use board_postclk_init instead of gclk_initHaavard Skinnemoen2008-09-01-3/+0
|/ | | | | | | | | | | | | | | | | | Replace the avr32-specific gclk_init() board hook with the standard board_postclk_init() hook which is supposed to run at the same point during initialization. Provide a dummy weak alias for boards not implementing this hook. The cost of this is: - 2 bytes for the dummy function (retal 0) - 2 bytes for each unnecessary function call (short rcall) which is a pretty small price to pay for avoiding lots of #ifdef clutter. In this particular case, all boards probably end up slightly smaller because we avoid the conditional checking if the gclk_init symbol is NULL.

* Add support for the hammerhead (AVR32) boardJulien May2008-07-30-0/+3
| | | | | | | | | | | | | | | | | | | | | The Hammerhead platform is built around a AVR32 32-bit microcontroller from Atmel. It offers versatile peripherals, such as ethernet, usb device, usb host etc. The board also incooperates a power supply and is a Power over Ethernet (PoE) Powered Device (PD). Additonally, a Cyclone III FPGA from Altera is integrated on the board. The FPGA is mapped into the 32-bit AVR memory bus. The FPGA offers two DDR2 SDRAM interfaces, which will cover even the most exceptional need of memory bandwidth. Together with the onboard video decoder the board is ready for video processing.

* avr32: Rename pm_init() as clk_init() and make SoC-specificHaavard Skinnemoen2008-05-27-43/+5
| | | | | | | | pm_init() was always more about clock initialization than anything else. Dealing with PLLs, clock gating and such is also inherently SoC-specific, so move it into a SoC-specific directory. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
* avr32: Get rid of the .flashprog sectionHaavard Skinnemoen2008-05-27-6/+0
| | | | | | | | | | | | The .flashprog section was only needed back when we were running directly from flash, and it's even more useless on NGW100 since it uses the CFI flash driver which never used this workaround in the first place. Remove it on STK1000 as well, and get rid of all the associated code and annotations. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
* avr32: Disable the AP7000 internal watchdog on startupDavid Brownell2008-05-27-0/+4
| | | | | | | | | This patch forces the watchdog off in all cases. That will at least get rid of the constant reboot cycle, though it won't let the watchdog actually run in the new kernels: its probe() comes up with a polite warning. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
* AVR32: Resource management rewriteHaavard Skinnemoen2007-04-14-9/+55
| | | | | | | | | | | | | 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.

* Add AT32AP CPU and AT32AP7000 SoC supportWolfgang Denk2006-10-24-0/+83
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.
