* [POWERPC] 8xx: Remove unused m8xx_cpm_hostalloc/free/dump()Jochen Friedrich2008-01-28
| | | | | | | | | m8xx_cpm_hostalloc is still defined in commproc.c, but no users are left in the kernel tree. m8xx_cpm_hostfree and m8xx_cpm_hostdump are only defined in the headers. Remove this dead code. Signed-off-by: Jochen Friedrich <jochen@scram.de> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* [POWERPC] 83xx: Add device tree source for Wind River SBC834x board.Paul Gortmaker2008-01-28
| | | | | | | | | | This adds the device tree source for the Wind River SBC834x board. It is based on the MPC834x_MDS DTS, with the biggest difference being the lack of BCSR and the PCI2 that the MDS gets via the PIB. That, and this file is also dts-v1 format.

* [POWERPC] 83xx: Add support for Wind River SBC834x boardsPaul Gortmaker2008-01-28
| | | | | | | | | This adds the basic support for the Wind River SBC834x boards. The SBC8349 is more common, although it should work on the SBC8347 board as well. Support is heavily based on the existing MPC834x_MDS code. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | This adds a v1 device tree source for the Wind River SBC8548 board. The biggest difference between this and the MPC8548CDS reference platform is the absence of the CDS's Arcadia peripherals and physical access to the PCI#2 bus.

* [POWERPC] CPM2: Make support for the CPM2 optional on 8560 based boardsPaul Gortmaker2008-01-28
| | | | | | | | | Currently there is no way to disable the CPM2 support.

* [POWERPC] Reduce code duplication in legacy_serial, add UART parent typesPaul Gortmaker2008-01-28
| | | | | | | | | | | The legacy_serial was treating each UART parent in a separate code block. Rather than continue this trend for the new parent IDs, this condenses all (soc, tsi, opb, plus two more new types) into one of_device_id array. The new types are wrs,epld-localbus for the Wind River sbc8560, and a more generic "simple-bus" as requested by Scott Wood.

* Revert "[POWERPC] Fake NUMA emulation for PowerPC"Paul Mackerras2008-01-26
| | | | | | | | | | | | | | | | | | This reverts commit 5c3f5892a2db6757a72ce8b27cba90db06683e1d, basically because it changes behaviour even when no fake NUMA information is specified on the kernel command line. Firstly, it changes the nid, thus destroying the real NUMA information. Secondly, it also changes behaviour in that if a node ends up with no memory in it because of the memory limit, we used to set it online and now we don't. Also, in the non-NUMA case with no fake NUMA information, we do node_set_online once for each LMB now, whereas previously we only did it once. I don't know if that is actually a problem, but it does seem unnecessary. Signed-off-by: Paul Mackerras <paulus@samba.org>

| * [POWERPC] Enable RTC for Ebony and Walnut (v2)David Gibson2008-01-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch extends the Ebony and Walnut platform code to instantiate the existing ds1742 RTC class driver for the DS1743 RTC/NVRAM chip found on both those boards. The patch uses a helper function to scan the device tree and instantiate the appropriate platform_device based on it, so it should be easy to extend for other boards which have mmio mapped RTC chips. Along with this, the device tree binding for the ds1743 chips is tweaked, based on the existing DS1385 OF binding found at: http://playground.sun.com/1275/proposals/Closed/Remanded/Accepted/346-it.txt Although that document covers the NVRAM portion of the chip, whereas here we're interested in the RTC portion, so it's not entirely clear if that's a good model. This implements only RTC class driver support - that is /dev/rtc0, not /dev/rtc, and the low-level get/set time callbacks remain unimplemented. That means in order to get at the clock you will either need a modified version of hwclock which will look at /dev/rtc0, or you'll need to configure udev to symlink rtc0 to rtc.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that all platforms using dma_direct_offset setup the archdata.dma_data correctly, we can change the dma_direct_ops to retrieve the offset from the dma_data, rather than directly from the global. While we're here, change the way the offset is used - instead of or'ing it into the value, add it. This should have no effect on current implementations where the offset is far larger than memory, however in future we may want to use smaller offsets.
