* avr32: Add simple paging supportHaavard Skinnemoen2010-09-03-0/+3
| | | | | | | | | | | | | | | | | | Use the MMU hardware to set up 1:1 mappings between physical and virtual addresses. This allows us to bypass the cache when accessing the flash without having to do any physical-to-virtual address mapping in the CFI driver. The virtual memory mappings are defined at compile time through a sorted array of virtual memory range objects. When a TLB miss exception happens, the exception handler does a binary search through the array until it finds a matching entry and loads it into the TLB. The u-boot image itself is covered by a fixed TLB entry which is never replaced. This makes the 'saveenv' command work again on ATNGW100 and other boards using the CFI driver, hopefully without breaking any rules. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
* Add "source" command; prepare removal of "autoscr" commandWolfgang Denk2009-04-03-1/+1
| | | | | | | | | | | | | | | | | | | | | According to the doc/feature-removal-schedule.txt, the "autoscr" command will be replaced by the "source" command in approximately 6 months from now. This patch prepares this change and starts a 6 month transition period as follows: - The new "source" command has been added, which implements exactly the same functionlaity as the old "autoscr" command before - The old "autoscr" command name is kept as an alias for compatibility - Command sequences, script files atc. have been adapted to use the new "source" command - Related environment variables ("autoscript", "autoscript_uname") have *not* been adapted yet; these will be renamed resp. removed in a separate patch when the support for the "autoscr" command get's finally dropped.

* | avr32: refactor the portmux/gpio codeHaavard Skinnemoen2008-09-01-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Separate the portmux configuration functionality from the GPIO pin control API. - Separate the controller-specific code from the chip-specific code. - Allow "ganged" port configuration (multiple pins at once). - Add more flexibility to the "canned" peripheral select functions: - Allow using more than 23 address bits, more chip selects, as well as NAND- and CF-specific pins. - Make the MACB SPEED pin optional, and choose between MII/RMII using a parameter instead of an #ifdef. - Make it possible to use other MMC slots than slot 0, and support different MMC/SDCard data bus widths. - Use more reasonable pull-up defaults; floating pins may consume a lot of power. - Get rid of some custom portmux code from the mimc200 board code. The old gpio/portmux API couldn't really handle its requirements, but the new one can. - Add documentation. The end result is slightly smaller code for all boards. Which isn't really the point, but at least it isn't any larger. This has been verified on ATSTK1002 and ATNGW100. I'd appreciate if the board maintainers could help me test this on their boards. In particular, the mimc200 port has lost a lot of code, so I'm hoping Mark can help me out.

* Fix printf() format problems with configurable promptsWolfgang Denk2008-07-31-2/+2
| | | | | | | | | | | | | | | U-Boot allows for configurable prompt strings using the CONFIG_AUTOBOOT_PROMPT resp. CONFIG_MENUPROMPT definitions. So far, the assumption was that any such user defined problts would contain exactly one "%d" format specifier. But some boards did not. To allow for flexible boot prompts without adding too complex code we now allow to specify the whole list of printf() arguments in the user definition. This is powerful, but requires a responsible user who really understands what he is doing, as he needs to know for exanple which variables are available in the respective context.

* ATSTK1002: Use SDRAM + 4MB as default load addressHaavard Skinnemoen2008-02-05-2/+2
| | | | | | | | | | Many people run into problems when they compile a big kernel and load the uImage at the default SDRAM + 2MB address as the kernel will overwrite the uImage as it is being unpacked.

* ATSTK1002: Remove default ethernet addressesHaavard Skinnemoen2007-11-01-8/+3
| | | | | | | | | | | | Wolfgang is right: It's not a good idea to set up default initial ethernet addresses for a board, even though they belong to the local range. This will change the failure mode from "IT manager screams at you for using duplicate ethernet addresses" to a nice error message explaining that the ethernet address hasn't been set properly.

|/ | | | | | | | | | | | | 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.
