* [MIPS] Split up war.hRalf Baechle2007-10-11
| | | | | | | | | | It was getting a little big, ugly and a primary source for merge conflicts. Also the old method was a bit too forgiving in that the workaround did default to off, so now there is an explicit #error forcing platform maintainers to think if they should enable a workaround for a particular platform.

* [MIPS] Make ioremap() work on TX39/49 special unmapped segmentAtsushi Nemoto2007-07-10
| | | | | | | | | | | | | TX39XX and TX49XX have "reserved" segment in CKSEG3 area. 0xff000000-0xff3fffff on TX49XX and 0xff000000-0xfffeffff on TX39XX are reserved (unmapped, uncached). Controllers on these SoCs are placed in this segment. This patch add plat_ioremap() and plat_iounmap() to override default behavior and implement these hooks for TX39/TX49.

| | | | | | | | | | This patch adds support for the generic GPIO API to Au1x00 boards. It requires the generic GPIO patch for MIPS boards by Yoichi Yuasa.

* au1550 SPI controller driverJan Nikitenko2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here is a driver for the Alchemy au1550 PSC (Programmable Serial Controller) in SPI master mode. It supports dma transfers using the Alchemy descriptor based dma controller for 4-8 bits per word SPI transfers. For 9-24 bits per word transfers, pio irq based mode is used to avoid setup of dma channels from scratch on each number of bits per word change. Tested with au1550; this may also work on other MIPS Alchemy cpus, like au1200/au1210/au1250. Used extensively with SD card connected via SPI; this handles 8.1MHz SPI clock transfers using dma without any problem (the highest SPI clock freq possible with au1550 running on 324MHz). The driver supports sharing of SPI bus by multiple devices. All features of Alchemy SPI mode are supported (all SPI modes, msb/lsb first, bits per word in 4-24 range). As the SPI clock of the controller depends on main input clock that shall be configured externally, platform data structure for au1550 SPI controller driver contains mainclk_hz attribute to define the input clock rate. From this value, dividers of the controller for SPI clock are set up for required frequency. Signed-off-by: Jan Nikitenko <jan.nikitenko@gmail.com> Whitespace and section fixups. Remove partial workaround for platform setup bug in dma_mask setup; it couldn't work with multiple controllers.

* ide: remove static prototypes from include/asm-mips/mach-au1x00/au1xxx_ide.hDaniel Mack2007-03-17
| | | | | | | | | | This patch removes the static prototypes from the au1xxx_ide.h, some of them were not even implemented. Also, they caused build breakage since they differed from the functions actually implemented in drivers/ide/mips/au1xxx-ide.c.

* [MIPS] Alchemy: Fix PCI-memory accessAlexander Bigga2007-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | | The problem was introduced in 2.6.18.3 with the casting of some 36bit-defines (PCI memory) in au1000.h to resource_size_t which may be u32 or u64 depending on the experimental CONFIG_RESOURCES_64BIT. With unset CONFIG_RESOURCES_64BIT, the pci-memory cannot be accessed because the ioremap in arch/mips/au1000/common/pci.c already used the truncated addresses. With set CONFIG_RESOURCES_64BIT, things get even worse, because PCI-scan aborts, due to resource conflict: request_resource() in arch/mips/pci/pci.c fails because the maximum iomem-address is 0xffffffff (32bit) but the pci-memory-start-address is 0x440000000 (36bit). To get pci working again, I propose the following patch: 1. remove the resource_size_t-casting from au1000.h again 2. make the casting in arch/mips/au1000/common/pci.c (it's allowed and necessary here. The 36bit-handling will be done in __fixup_bigphys_addr). With this patch pci works again like in 2.6.18.2, the gcc-compile warnings in pci.c are gone and it doesn't depend on CONFIG_EXPERIMENTAL.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
