* powerpc: Add a 6xx defconfigKumar Gala2008-07-221-0/+3304
| | | | | | | | | This is a defconfig from Dave Jones and should be similar (if not identical) to the fedora ppc32 defconfig. The intent is to cover all cache coherent 6xx based chips and platforms as reasonable.

* powerpc/cell: Add support for power button of future IBM cell bladesChristian Krafft2008-07-224-0/+128
| | | | | | | | | | | | | This patch adds support for the power button on future IBM cell blades. It actually doesn't shut down the machine. Instead it exposes an input device /dev/input/event0 to userspace which sends KEY_POWER if power button has been pressed. haldaemon actually recognizes the button, so a plattform independent acpid replacement should handle it correctly.

* powerpc/cell/cpufreq: Add spu aware cpufreq governorChristian Krafft2008-07-223-0/+194
| | | | | | | | | | | | | This patch adds a cpufreq governor that takes the number of running spus into account. It's very similar to the ondemand governor, but not as complex. Instead of hacking spu load into the ondemand governor it might be easier to have cpufreq accepting multiple governors per cpu in future. Don't know if this is the right way, but it would keep the governors simple.

| | | | | | | | | | | DDR2 memory DIMMs on the Axon could be accessed only as one partition when using file system drivers which are using the direct_access() method.

* Revert "powerpc/ep8248e: Fix compile problem if !CONFIG_FS_ENET"Kumar Gala2008-07-161-4/+0
| | | | | | | This reverts commit e3621ee633810be1079d0fa65ac2c904f53b73fa. This was not the proper fix. As Scott Wood said CONFIG_FS_ENET has nothing to do with the issue. The proper fix is to select PHYLIB for this board.
* powerpc/ep8248e: Unconditionally select PHYLIB for mdio_bitbangKumar Gala2008-07-161-0/+1
| | | | | | | | | | | | | | | Its possible to build the phylib as a module, however this breaks the board code because alloc_mdio_bitbang and mdiobus_register are not available if we build as a module. These are needed by the board code since it implements the low level mdio bitbang ops. So we unconditionally select PHYLIB to ensure its built into the kernel if we are building in EP8248E support. Long term we should look at moving the mdio_ops into its own file so it can be built as a module. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | | This converts the FSL Book-E PTE access and TLB miss handling to match with the recent changes to 44x that introduce support for non-atomic PTE operations in pgtable-ppc32.h and removes write back to the PTE from the TLB miss handlers. In addition, the DSI interrupt code no longer tries to fixup write permission, this is left to generic code, and _PAGE_HWWRITE is gone. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | | The old code assumed there was only one, but the 8572 actually has 3. Also, our usual id, 0xe0024520, gets resolved to -1 somewhere, and this was preventing the multiple buses from having different ids.

| | | | | | | | | | | | The ULI "Super South Bridge" contains ISA bridge to the legacy devices, such as Super IO mouse/keyboard/floppy disk controllers, parallel port, i8259 interrupt controller and so on. i8259 is disabled on the MPC8610HPCD, and other peripherals are not traced out.

* powerpc/85xx/86xx: some refactoring for fsl_uli1575 codeAnton Vorontsov2008-07-165-99/+108
| | | | | | | | | | | | - Get rid of uses_fsl_uli_m1575, it does not scale for all cases. Instead, let's explicitly use machine_is() for each fixup. - Factor out MPC8610HPCD quirks to fsl_uli1575, and protect them with machine_is(). One step closer to multiplatform kernels. - Actually use fsl_uli1575 on MPC8610HPCD, so RTC quirk will be applied. - RTC quirk applies to all boards though, so no machine_is() checks.

| | | | | | | | | | | | This patch fixes RTC on MPC8572DS boards: dummy read helps only when reading at the end of the bridge's memory (i.e. outside of behind the bridge devices' assigned regions). With this change the quirk also makes RTC work on MPC8610HPCD, so it's unlikely that this will break MPC8641HPCN or MPC8544DS boards.

* powerpc: pci config cleanupJohn Rigby2008-07-1610-5/+19
| | | | | | | | | | | | | | | | | | | | Choosing PCI or not at config time is allowed on some platforms via an if expression in arch/powerpc/Kconfig. To add a new platform with PCI support selectable at config time, you must change the if expression. This patch makes this easier by changing: bool "PCI support" if <long expression> to bool "PCI support" if PPC_PCI_CHOICE and adding select PPC_PCI_CHOICE to all the config nodes that were previously in the PCI if expression. Platforms with unconditional PCI support continue to just select PCI in their config nodes.

* powerpc/mpc7448: add alias list to DTS, clean out old chosen nodePaul Gortmaker2008-07-161-9/+15
| | | | | | | | | | | | | | | | | The mpc7448hpc2 board doesn't have an alias block like most of the other modern eval boards have. We need this block in order to have u-boot be able to make use of the CONFIG_OF_STDOUT_VIA_ALIAS (vs. having a hard coded node) in the future. Also remove the old, redundant chosen node. Of all the modern Freescale eval boards (incl. 83xx, 85xx, 86xx) this is the only one which still has it. Its presence also breaks with some older versions of u-boot, like 1.3.1 -- which try and insert a second chosen node.

It should in theory work on AT91 systems too with some tweaking, but since the DMA interface is quite different, it's not entirely clear if it's worth merging this with the at91_mci driver. This driver has been around for a while in BSPs and kernel sources provided by Atmel, but this particular version uses the generic DMA Engine framework (with the slave extensions) instead of an avr32-only DMA controller framework. This driver can also use PIO transfers when no DMA channels are available, and for transfers where using DMA may be difficult or impractical for some reason (e.g. the DMA setup overhead is usually not worth it for very short transfers, and badly aligned buffers or lengths are difficult to handle.) Currently, the driver only support PIO transfers. DMA support has been split out to a separate patch to hopefully make it easier to review. The driver has been tested using mmc-block and ext3fs on several SD, SDHC and MMC+ cards. Reads and writes work fine, with read transfer rates up to 3.5 MiB/s on fast cards with debugging disabled. The driver has also been tested using the mmc_test module on the same cards. All tests except 7, 9, 15 and 17 succeed. The first two are unsupported by all the cards I have, so I don't know if the driver handles this correctly. The last two fail because the hardware flags a Data CRC Error instead of a Data Timeout error. I'm not sure how to deal with that. Documentation for this controller can be found in many data sheets from Atmel, including the AT32AP7000 data sheet which can be found here: http://www.atmel.com/dyn/products/datasheets.asp?family_id=682 Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
