* powerpc/booke: Add kprobes support for booke style processorsKumar Gala2008-06-262-15/+36
| | | | | | | | | | This patch is based on work done by Madhvesh. R. Sulibhavi back in March 2007. We refactor some of the single step handling since it differs between "classic" and "booke" powerpc cores. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* powerpc/kprobes: Some minor fixesKumar Gala2008-06-262-1/+10
| | | | | | | | | | | | | | * Mark __flush_icache_range as a function that can't be probed since its used by the kprobe code. * Fix an issue with single stepping and async exceptions. We need to ensure that we dont get an async exception (external, decrementer, etc) while we are attempting to single step the probe point. Added a check to ensure we only handle a single step if its really intended for the instruction in question. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* powerpc/e500mc: flush L2 on NAP for e500mcKumar Gala2008-06-261-0/+9
| | | | | | | | | | | | If we have an L2CSR register (e500mc) we need to flush the L2 before going to nap. We use the HW flush mechanism provided in that register. The code reuses the CPU_FTR_604_PERF_MON bit as it is no longer used by any code in the kernel. Additionally we didn't reuse the exist L2CR feature bit as this is intended for the 7xxx L2CR register and L2CSR is part of the new Freescale "Book-E" registers.

* powerpc/QE: switch to the cpm_muram implementationAnton Vorontsov2008-06-103-95/+14
| | | | | | | | | | | | | | | | | | This is very trivial patch. We're transitioning to the cpm_muram_* calls. That's it. Less trivial changes: - BD_SC_* defines were defined in the cpm.h and qe.h, so to avoid redefines we remove BD_SC from the qe.h and use cpm.h along with cpm_muram_* prototypes; - qe_muram_dump was unused and thus removed; - added some code to the cpm_common.c to support legacy QE bindings (data-only node name). - For convenience, define qe_* calls to cpm_*. So drivers need not to be changed. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* powerpc/83xx: new board support: MPC8360E-RDKAnton Vorontsov2008-06-105-0/+1639
| | | | | | | | | | | | | | | | | | | | | | | | | This is patch adds board file, device tree, and defconfig for the new board, made by Freescale Semiconductor Inc. and Logic Product Development. Currently supported: 1. UEC{1,2,7,4}; 2. I2C; 3. SPI; 4. NS16550 serial; 5. PCI and miniPCI; 6. Intel NOR StrataFlash X16 64Mbit PC28F640P30T85; 7. Graphics controller, Fujitsu MB86277. Not supported in this patch: 1. StMICRO NAND512W3A2BN6E, 512 Mbit (supported with FSL UPM NAND driver); 2. FHCI USB (supported with FHCI driver). 3. QE Serial UCCs (tested to not work with ucc_uart driver, reason unknown, yet); 4.

* powerpc/QE: add support for QE USB clocks routingAnton Vorontsov2008-06-104-3/+64
| | | | | | | | | | | | | | | | This patch adds a function to the qe_lib to setup QE USB clocks routing. To setup clocks safely, cmxgcr register needs locking, so I just reused ucc_lock since it was used only to protect cmxgcr. The idea behind placing clocks routing functions into the qe_lib is that later we'll hopefully switch to the generic Linux Clock API, thus, for example, FHCI driver may be used for QE and CPM chips without nasty #ifdefs. This patch also fixes QE_USB_RESTART_TX command definition in the qe.h.

* powerpc/sysdev: implement FSL GTM supportAnton Vorontsov2008-06-103-0/+441
| | | | | | | | | | | | | | | | | | | | GTM stands for General-purpose Timers Module and able to generate timer{1,2,3,4} interrupts. These timers are used by the drivers that need time precise interrupts (like for USB transactions scheduling for the Freescale USB Host controller as found in some QE and CPM chips), or these timers could be used as wakeup events from the CPU deep-sleep mode. Things unimplemented: 1. Cascaded (32 bit) timers (1-2, 3-4). This is straightforward to implement when needed, two timers should be marked as "requested" and configured as appropriate. 2. Super-cascaded (64 bit) timers (1-2-3-4). This is also straightforward to implement when needed, all timers should be marked as "requested" and configured as appropriate.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ehea driver was recently changed[1] to use walk_memory_resource() to detect the system's memory layout.

| | * PCI/x86: fix up PCI stuff so that PCI_GOANY supports OLPCAndres Salomon2008-06-054-10/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, one would have to specifically choose CONFIG_OLPC and CONFIG_PCI_GOOLPC in order to enable PCI_OLPC. That doesn't really work for distro kernels, so this patch allows one to choose CONFIG_OLPC and CONFIG_PCI_GOANY in order to build in OLPC support in a generic kernel (as requested by Robert Millan). This also moves GOOLPC before GOANY in the menuconfig list. Finally, make pci_access_init return early if we detect OLPC hardware. There's no need to continue probing stuff, and pci_pcbios_init specifically trashes our settings (we didn't run into that before because PCI_GOANY wasn't supported).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes os_get_task_size locate the bottom of the address space, as well as the top. This is for systems which put a lower limit on mmap addresses. It works by manually scanning pages from zero onwards until a valid page is found. Because the bottom of the address space may not be zero, it's not sufficient to assume the top of the address space is the size of the address space. The size is the difference between the top address and bottom address. [jdike@addtoit.com: changed the name to reflect that this function is supposed to return the top of the process address space, not its size and changed the return value to reflect that.
