git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc Pull powerpc merge from Benjamin Herrenschmidt: "Here's the powerpc batch for this merge window. It is going to be a bit more nasty than usual as in touching things outside of arch/powerpc mostly due to the big iSeriesectomy :-) We finally got rid of the bugger (legacy iSeries support) which was a PITA to maintain and that nobody really used anymore. Here are some of the highlights: - Legacy iSeries is gone. Thanks Stephen ! There's still some bits and pieces remaining if you do a grep -ir series arch/powerpc but they are harmless and will be removed in the next few weeks hopefully. - The 'fadump' functionality (Firmware Assisted Dump) replaces the previous (equivalent) "pHyp assisted dump"... it's a rewrite of a mechanism to get the hypervisor to do crash dumps on pSeries, the new implementation hopefully being much more reliable. Thanks Mahesh Salgaonkar. - The "EEH" code (pSeries PCI error handling & recovery) got a big spring cleaning, motivated by the need to be able to implement a new backend for it on top of some new different type of firwmare. The work isn't complete yet, but a good chunk of the cleanups is there. Note that this adds a field to struct device_node which is not very nice and which Grant objects to. I will have a patch soon that moves that to a powerpc private data structure (hopefully before rc1) and we'll improve things further later on (hopefully getting rid of the need for that pointer completely). Thanks Gavin Shan. - I dug into our exception & interrupt handling code to improve the way we do lazy interrupt handling (and make it work properly with "edge" triggered interrupt sources), and while at it found & fixed a wagon of issues in those areas, including adding support for page fault retry & fatal signals on page faults. - Your usual random batch of small fixes & updates, including a bunch of new embedded boards, both Freescale and APM based ones, etc..."

Commit c55aef0e5bc6 "powerpc/boot: Change the load address for the wrapper to fit the kernel" adjusted the laod address if the uncompressed kernel was too large. Ps3 does not compress the kernel and uses a different linker script, so do not adjust the load address in that case. fixes this build error: powerpc64-linux-ld: section .text loaded at [0000000000e00000,0000000000e0721b] overlaps section .kernel:dtb loaded at [0000000000e00000,0000000000e0066f] Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

2012-03-16powerpc/85xx: p1022ds: disable the NOR flash node if video is enabledTimur Tabi
The Freescale P1022 has a unique pin muxing "feature" where the DIU video controller's video signals are muxed with 24 of the local bus address signals. When the DIU is enabled, the bulk of the local bus is disabled, preventing access to memory-mapped devices like NOR flash and the pixis FPGA. Therefore, if the DIU is going to be enabled, then memory-mapped devices on the localbus, like NOR flash, need to be disabled. This also means that the localbus is not a 'simple-bus' any more, so remove that string from the compatible node.

2012-03-16powerpc/85xx: p2020rdb & p1010rdb - lower spi flash freq to 40MhzSebastian Andrzej Siewior
This is here most likely since the FSL bsp. Back in the FSL bsp it was set to 50Mhz and working. However the driver divided the SoC freq. only by 2. According to the TRM the platform clock (which the manual refers in its formula) is the system clock divided by two. So in the end it has to divide by 4 and this is what the fsl-spi driver in tree is doing. Since then the flash is not wokring I guess. After chaning the freq from 50Mhz to 40Mhz like others do then I can access the flash.

The FreeScale PowerQUICC-III-compatible (mpc85xx/mpc86xx) MPICs do not correctly report the number of hardware interrupt sources, so software needs to override the detected value with "256".

The Freescale MPIC (and perhaps others in the future) is incapable of routing non-IPI interrupts to more than once CPU at a time. Currently all of the Freescale boards msut pass the MPIC_SINGLE_DEST_CPU flag to mpic_alloc(), but that information should really be present in the device-tree. Older board code can't rely on the device-tree having the property set, but newer platforms won't need it manually specified in the code.

2012-02-23fsl/mpic: Document and use the "big-endian" device-tree flagKyle Moffett
The MPIC code checks for a "big-endian" property and sets the flag MPIC_BIG_ENDIAN if one is present, although prior to the "mpic->flags" fixup that would never have worked anways. Unfortunately, even now that it works properly, the Freescale mpic device-node (the "PowerQUICC-III"-compatible one) does not specify it, so all of the board ports need to manually pass it to mpic_alloc(). Document the flag and add it to the pq3 device tree. Existing code will still need to pass the MPIC_BIG_ENDIAN flag because their dtb may not have this property, but new platforms shouldn't need to do so.

This hooks dtc into Kbuild's dependency system. Thus, for example, "make dtbs" will rebuild tegra-harmony.dtb if only tegra20.dtsi has changed yet tegra-harmony.dts has not. The previous lack of this feature recently caused me to have very confusing "git bisect" results. For ARM, it's obvious what to add to $(targets). I'm not familiar enough with other architectures to know what to add there. Powerpc appears to already add various .dtb files into $(targets), but the other archs may need something added to $(targets) to work.

2012-01-04powerpc: Add TBI PHY node to first MDIO busAndy Fleming
Systems which use the fsl_pq_mdio driver need to specify an address for TBI PHY transactions such that the address does not conflict with any PHYs on the bus (all transactions to that address are directed to the onboard TBI PHY). The driver used to scan for a free address if no address was specified, however this ran into issues when the PHY Lib was fixed so that all MDIO transactions were protected by a mutex. As it is, the code was meant to serve as a transitional tool until the device trees were all updated to specify the TBI address. The best fix for the mutex issue was to remove the scanning code, but it turns out some of the newer SoCs have started to omit the tbi-phy node when SGMII is not being used. As such, these devices will now fail unless we add a tbi-phy node to the first mdio controller.

2011-12-21powerpc/boot: Change the WARN to INFO for boot wrapper overlap messageSuzuki Poulose
commit c55aef0e5bc6 ("powerpc/boot: Change the load address for the wrapper to fit the kernel") introduced a WARNING to inform the user that the uncompressed kernel would overlap the boot uncompressing wrapper code. Change it to an INFO. I initially thought, this would be a 'WARNING' for the those boards, where the link_address should be fixed, so that the user can take actions accordingly. Changing the same to INFO. Signed-off-by: Suzuki K. Poulose <suzuki@in.ibm.com> Signed-off-by: Josh Boyer <jwboyer@gmail.com>
2011-12-20powerpc/boot: Change the load address for the wrapper to fit the kernelSuzuki Poulose
The wrapper code which uncompresses the kernel in case of a 'ppc' boot is by default loaded at 0x00400000 and the kernel will be uncompressed to fit the location 0-0x00400000. But with dynamic relocations, the size of the kernel may exceed 0x00400000(4M). This would cause an overlap of the uncompressed kernel and the boot wrapper, causing a failure in boot. The message looks like : zImage starting: loaded at 0x00400000 (sp: 0x0065ffb0) Allocating 0x5ce650 bytes for kernel ... Insufficient memory for kernel at address 0! (_start=00400000, uncompressed size=00591a20) This patch shifts the load address of the boot wrapper code to the next higher MB, according to the size of the uncompressed vmlinux. With the patch, we get the following message while building the image : WARN: Uncompressed kernel (size 0x5b0344) overlaps the address of the wrapper(0x400000) WARN: Fixing the link_address of wrapper to (0x600000) Signed-off-by: Suzuki K.

2011-12-09powerpc/boot: Add extended precision shifts to the boot wrapper.Tony Breeds
The upcomming currituck patches will need to do 64-bit shifts which will fail with undefined symbol without this patch. I looked at linking against libgcc but we can't guarantee that libgcc was compiled with soft-float. Also Using ../lib/div64.S or ../kernel/misc_32.S, this will break the build as the .o's need to be built with different flags for the bootwrapper vs the kernel. So for now the easyest option is to just copy code from arch/powerpc/kernel/misc_32.S I don't think this code changes too often ;P Signed-off-by: Tony Breeds <tony@bakeyournoodle.com> Signed-off-by: Josh Boyer <jwboyer@gmail.com>
