2008-04-07[POWERPC] Remove CONFIG_PCI_LEGACY from some configsStephen Rothwell
This will remove some build warnings and doesn't stop us building any drivers that we were building previously with these configs. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2008-04-07[POWERPC] htab_remove_mapping is only used by MEMORY_HOTPLUGStephen Rothwell

2008-04-07[POWERPC] Convert pci and eeh code to of_device_is_availableNathan Lynch
A couple of places are duplicating the function of of_device_is_available; convert them to use it. Signed-off-by: Nathan Lynch <ntl@pobox.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2008-04-07[POWERPC] Add of_device_is_available functionJosh Boyer
IEEE 1275 defined a standard "status" property to indicate the operational status of a device. The property has four possible values: okay, disabled, fail, fail-xxx. The absence of this property means the operational status of the device is unknown or okay. This adds a function called of_device_is_available that checks the state of the status property of a device. If the property is absent or set to either "okay" or "ok", it returns 1. Otherwise it returns 0. Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2008-04-07[POWERPC] Enable CONFIG_FORCE_MAX_ZONEORDER for all PowerPC, and make selectableTimur Tabi
This enables the FORCE_MAX_ZONEORDER Kconfig option for all PowerPC systems. Previously, it was enabled only for 64-bit systems. We also make the option selectable from the menu, so that the user can specify different values. This is useful for 32-bit systems that need to allocate more than 4MB of physically contiguous memory.

2008-04-07[POWERPC] Fix kernel panic in arch_arm_kprobeIonut Nicu
The code in arch_arm_kprobe was trying to set a breakpoint which resulted in a page fault because the kernel text pages were write protected. Disable the write protect when CONFIG_KPROBES is defined.

2008-04-07[POWERPC] Add hand-coded assembly strcmpSteven Rostedt
We have an assembly version of strncmp for the bootwrapper, but not for the kernel, so we end up using the C version in the kernel. This takes the strncmp code from the bootup and copies it to the kernel proper, adding two instructions so it copes correctly with len==0.

2008-04-05[POWERPC] 4xx: Add Canyonlands and Yosemite to multi-board defconfigJosh Boyer

2008-04-05[POWERPC] 4xx: Use machine_device_initcall() for warp_nandValentine Barshak
With a multiplatform kernel, once built we always have warp_setup_nand_flash() called and NDFC probed, no matter what machine we actually run on. This potentially can cause problems (such as kernel crash), since NDFC is probed at a warp-predefined address. Using machine_device_initcall() NAND devices are registered if we run on a warp only.

2008-04-05[POWERPC] 4xx: Change dts files to support jumbo framesStefan Roese
This patch changes the "max-frame-size" property to 9000 for all gbit enabled 4xx boards. All those ports generally support jumbo frames, so let's give the user a chance to enable it. Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>
2008-04-05[POWERPC] 4xx: Some EMAC related changes in Canyonlands & Glacier dts filesStefan Roese
This patch fixes some problems in the Canyonlands 460EX and Glacier 460GT dts files: - Add "mdio-device = <&EMAC0>" to all all EMAC's except for EMAC0 itself (the 460EX/GT only can access the PHY via the EMAC0 instance) - Add TAH support to Canyonlands dts Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>
2008-04-02[POWERPC] 4xx: Create common ppc4xx_reset_system() in ppc4xx_soc.cStefan Roese
This patch creates a common system reset routine for all 40x and 44x systems. Previously only a 44x routine existed. But since this system reset via the debug control register is common for 40x and 44x let's share this code for all those platforms in ppc4xx_soc.c. This patch also enables CONFIG_4xx_SOC for all 40x and 44x platforms. Tested on Kilauea (405EX) and Canyonlands (440EX).

2008-04-02[POWERPC] bootwrapper: Add a firmware-independent simpleboot target.Grant Likely
This target produces a flat binary rather than an ELF file, fixes the entry point at the beginning of the image, and takes a complete device tree with no fixups needed. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>
2008-04-02[POWERPC] of_serial: Fix possible null dereference.Stephen Neuendorffer
The of_serial driver queries the current-speed property and attempts to use it to register the custom_divisor property of the uart_port. However, if current-speed is not set, then this code will dereference a bad pointer. The fix is to only set custom_divisor when a current-speed property appears in the device tree.

2008-04-02[POWERPC] 4xx: Only reset PCIe PHY on 405EX systems when no link is detectedStefan Roese
Since the arch/powerpc PCI subsystem now does a complete re-assignment of the resources, we can move from the unconditional PCIe PHY reset to the conditional version. Now the PHY is only reset, if no link is established yet. An additional PHY reset (one is already done in U-Boot) leads to problems with some Atheros PCIe boards and some HP FPGA PCIe designs.

2008-04-02[POWERPC] add target for building .dtb filesGrant Likely

Split the device setup code in ps3_register_repository_device() in two routines: 1. ps3_setup_static_device(), to handle the setup of static devices in the PS3 repository, which can be __init, 2. ps3_setup_dynamic_device(), to handle the setup of storage devices that may appear later in the PS3 repository.

2008-03-26[POWERPC] Xilinx: hwicap: Verify sync before reading idcode.Stephen Neuendorffer
It appears that in some cases, the sync word might not be recognized by the hardware correctly. If this happens, then attempting to read from the port results in an unrecoverable error because of the design of the FPGA core. This patch updates the code to check the status of the device before reading the IDCODE, in order to avoid entering this unrecoverable state. This patch also adds additional NOOP commands into the sychronization sequence, which appears to be necessary to avoid the condition on some hardware.
