* avr32: Rework SDRAM initialization codeHaavard Skinnemoen2008-05-27-5/+42
| | | | | | | | | | | | | | This cleans up the SDRAM initialization and related code a bit, and allows faster booting. * Add definitions for EBI and internal SRAM to asm/arch/memory-map.h * Remove memory test from sdram_init() and make caller responsible for verifying the SDRAM and determining its size. * Remove base_address member from struct sdram_config (was sdram_info) * Add data_bits member to struct sdram_config and kill CFG_SDRAM_16BIT * Add support for a common STK1000 hack: 16MB SDRAM instead of 8.

* avr32: Rename pm_init() as clk_init() and make SoC-specificHaavard Skinnemoen2008-05-27-0/+2
| | | | | | | | 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: Clean up the HMATRIX codeHaavard Skinnemoen2008-05-27-232/+192
| | | | | | | | | | | | | Rework the HMATRIX configuration interface so that it becomes easier to configure the HMATRIX for boards with special needs, and add new parts. The HMATRIX header file has been split into a general, chip-independent part with register definitions, etc. and a chip-specific part with SFR bitfield definitions and master/slave identifiers.

* avr32: Get rid of the .flashprog sectionHaavard Skinnemoen2008-05-27-7/+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>

* | Big white-space cleanup.Wolfgang Denk2008-05-21-3/+3
|/ | | | | | | | | | | This commit gets rid of a huge amount of silly white-space issues.

Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>

* Remove the __STRICT_ANSI__ check from the __u64/__s64 declaration on 32bit ↵Shinya Kuribayashi2008-02-23-3/+3

GCC can be made to warn about usage of long long types with ISO C90 (-ansi), but only with -pedantic. You can write this in a way that even then it doesn't cause warnings, namely by: #ifdef __GNUC__ __extension__ typedef __signed__ long long __s64; __extension__ typedef unsigned long long __u64; #endif The __extension__ keyword in front of this switches off any pedantic warnings for this expression.

* AVR32: Make SDRAM refresh rate configurableHaavard Skinnemoen2008-02-05-0/+6
| | | | | | | | | | | | | | 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: Rename at32ap7000 -> at32ap700xHaavard Skinnemoen2007-12-17-0/+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>
* | Introduce map_physmem() and unmap_physmem()Haavard Skinnemoen2007-12-13-0/+32
|/ | | | | | | | | | | | | | | | map_physmem() returns a virtual address which can be used to access a given physical address without involving the cache. unmap_physmem() should be called when the virtual address returned by map_physmem() is no longer needed. This patch adds a stub implementation which simply returns the physical address cast to a uchar * for all architectures except AVR32, which converts the physical address to an uncached virtual mapping. unmap_physmem() is a no-op on all architectures, but if any architecture needs to do such mappings through the TLB, this is the hook where those TLB entries can be invalidated.

| * Atmel MCI driverHaavard Skinnemoen2007-04-14-0/+96
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * AVR32: Resource management rewriteHaavard Skinnemoen2007-04-14-152/+272
| | | | | | | | | | | | | | | | | | | | | | | | | | 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/+439
| | | | | | | | | | | | | | | | | | | | | | 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.
