| | * powerpc/85xx: Introduce support for the Freescale P1022DS reference boardTimur Tabi2010-08-046-44/+814
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce basic support for the Freescale P1022DS reference board, based on the Freescale BSP for this board. This patch excludes the DIU, SSI, and MMC/SD drivers. Only a 36-bit DTS is provided. Update mpc86xx_smp_defconfig and mpc85xx_defconfig to support the P1022DS. This means enabling 64-bit physical address support, increasing the maximum zone order to 12 (to allow the DIU driver to allocate large chunks), and clean up the audio options to disable the deprecated OSS support.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This version uses "fsl,mpc8555..." instead of "fsl,85..." notation. There is also an 8541 version of this board so DTS for this board is specific to the 8555 processor. Another patch is coming to fix-up other DTS that use old notation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mpc85xx_mds_setup_arch() function is incomprehensible and unmaintainable. Factor out all QE specific stuff into mpc85xx_mds_qe_init() and mpc85xx_mds_reset_ucc_phys(). Also move QE stuff out of mpc85xx_mds_pic_init().

| | * powerpc/85xx: Fix booting for P1021MDS boardsAnton Vorontsov2010-08-042-6/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | P1021 processors have no dedicated ROM to store the QE microcode, so the fimrware is stored externally, and it is U-Boot responsibility to load it. It might be that the board is booting without QE, e.g. currently U-Boot doesn't support QE for P1021MDS boards, which means that QE isn't initialized, and so the board hangs early at boot. This patch fixes the issue by marking QE as disabled and checking the state in the probing code. U-Boot should fixup the state if it initialized the QE.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code inside '#ifdef CONFIG_QUICC_ENGINE' makes the mpc85xx_mds_setup_arch() return early if no QE nodes present, and so SWIOTLB is never initialized.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MPC5121 DIU configuration/setup as initialized by the boot loader currently will get lost while booting Linux. As a result displaying the boot splash is not possible through the boot process. To prevent this we reserve configured DIU frame buffer address range while booting and preserve AOI descriptor and gamma table so that DIU continues displaying through the whole boot process. On first open from user space DIU frame buffer driver releases the reserved frame buffer area and continues to operate as usual.

| * | powerpc/kexec: Fix orphaned offline CPUs across kexecMatt Evans2010-07-311-1/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When CPU hotplug is used, some CPUs may be offline at the time a kexec is performed. The subsequent kernel may expect these CPUs to be already running, and will declare them stuck. On pseries, there's also a soft-offline (cede) state that CPUs may be in; this can also cause problems as the kexeced kernel may ask RTAS if they're online -- and RTAS would say they are. The CPU will either appear stuck, or will cause a crash as we replace its cede loop beneath it. This patch kicks each present offline CPU awake before the kexec, so that none are forever lost to these assumptions in the subsequent kernel. Now, the behaviour is that all available CPUs that were offlined are now online & usable after the kexec. This mimics the behaviour of a full reboot (on which all CPUs will be restarted).

| * | powerpc: ONLINE to OFFLINE CPU state transition during removalRobert Jennings2010-07-311-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a CPU remove is attempted using the 'release' interface on hardware which supports extended cede, the CPU will be put in the INACTIVE state rather than the OFFLINE state due to the default preferred_offline_state in that situation. In the INACTIVE state it will fail to be removed. This patch changes the preferred offline state to OFFLINE when an CPU is in the ONLINE state. After cpu_down() is called in dlpar_offline_cpu() the CPU will be OFFLINE and CPU removal can continue.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While testing cpu offlining, we are regularly seeing the WARN_ON go off in xics_ipi_dispatch. It can occur when an IPI gets sent to the CPU while it is going offline. There is already a similar WARN_ON in the handlers for PPC_MSG_CALL_FUNCTION and PPC_MSG_CALL_FUNC_SINGLE, so the warning is not needed in that path. The debugger handler handles this case by simply ignoring IPIs for offline CPUs, so no warning is needed there. And the reschedule IPI, which is what is occurring in our test environment, can be safely ignored, so we can simply remove the WARN_ON from xics_ipi_dispatch.

| | * | powerpc/40x: Distinguish AMCC PowerPC 405EX and 405EXr correctlyLee Nipper2010-07-261-7/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent AMCC 405EX Rev D without Security uses a PVR value that matches the old 405EXr Rev A/B with Security. The 405EX Rev D without Security would be shown incorrectly as an 405EXr. The pvr_mask of 0xffff0004 is no longer sufficient to distinguish the 405EX from 405EXr. This patch replaces 2 entries in the cpu_specs table and adds 8 more, each using pvr_mask of 0xffff000f and appropriate pvr_value to distinguish the AMCC PowerPC 405EX and 405EXr instances. The cpu_name for these entries now includes the Rev, in similar fashion to the 440GX. Signed-off-by: Lee Nipper <lee.nipper@gmail.com> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>
| | * | powerpc/44x: Fix UART2/3 interrupt assignment in PPC460EX/GT dts filesStefan Roese2010-07-262-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | UART2 and UART3 on 460EX/GT have incorrect interrupt mappings right now. UART2 should be 28 (0x1c) and UART3 29 (0x1d). This patch fixes this and switches to using decimal number instead of hex, since the AppliedMicro (AMCC) users manuals describe their inerrupt numbers in decimal. Thanks to Fabien Proriol for pointing this out.

| | * | Remove REDWOOD_[456] config options and conditional codeChristian Dietrich2010-07-261-16/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The config options for REDWOOD_[456] were commented out in the powerpc Kconfig. The ifdefs referencing this options therefore are dead and all references to this can be removed (Also dependencies in other KConfig files).

| * | | powerpc/book3e: Fix single step when using HW page tablesBenjamin Herrenschmidt2010-07-142-4/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We patch the TLB miss exception vectors to point to alternate functions when using HW page table on BookE. However, we were patching in a new branch in the first instruction of the exception handler instead of the second one, thus overriding the nop that is in the first instruction. This cause problems when single stepping as we rely on that nop for the single step to stop properly within the exception vector range rather than on the target of the branch.

| * | | powerpc/book3e: Add generic 64-bit idle powersave supportBenjamin Herrenschmidt2010-07-144-1/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We use a similar technique to ppc32: We set a thread local flag to indicate that we are about to enter or have entered the stop state, and have fixup code in the async interrupt entry code that reacts to this flag to make us return to a different location (sets NIP to LINK in our case).

| * | | powerpc/book3e: Resend doorbell exceptions to ourselfMichael Ellerman2010-07-093-2/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we are soft disabled and receive a doorbell exception we don't process it immediately. This means we need to check on the way out of irq restore if there are any doorbell exceptions to process. The problem is at that point we don't know what our regs are, and that in turn makes xmon unhappy. To workaround the problem, instead of checking for and processing doorbells, we check for any doorbells and if there were any we send ourselves another.
