| * | | [POWERPC] cell: Move cbe_regs.h to include/asm-powerpc/cell-regs.hBenjamin Herrenschmidt2007-10-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new Cell EDAC driver needs that file, oprofile also does ugly path tricks to get to it, it's time to move it to asm-powerpc. While at it, rename it to be consistent with cell-pmu.h (and dashes look nicer than underscores anyway).

| * | | [POWERPC] Remove unused old code from powermac setup codePaul Mackerras2007-10-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since bootdevice never gets initialized, it's always NULL, and hence a whole pile of code in arch/powerpc/platforms/setup.c never gets used. (This was the code that originally was there so that the automatic root partition selection mechanism would prefer a rootish-looking partition on the device that OF loaded the kernel from over a similar partition on other devices.) This removes the unused code. Signed-off-by: Paul Mackerras <paulus@samba.org> Acked-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

| * | [POWERPC] QEIC: Implement pluggable handlers, fix MPIC cascadingAnton Vorontsov2007-10-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | set_irq_chained_handler overwrites MPIC's handle_irq function (handle_fasteoi_irq) thus MPIC never gets eoi event from the cascaded IRQ. This situation hangs MPIC on MPC8568E. To solve this problem efficiently, QEIC needs pluggable handlers, specific to the underlaying interrupt controller. Patch extends qe_ic_init() function to accept low and high interrupt handlers. To avoid #ifdefs, stack of interrupt handlers specified in the header file and functions are marked 'static inline', thus handlers are compiled-in only if actually used (in the board file). Another option would be to lookup for parent controller and automatically detect handlers (will waste text size because of never used handlers, so this option abolished). qe_ic_init() also changed in regard to support multiplexed high/low lines as found in MPC8568E-MDS, plus qe_ic_cascade_muxed_mpic() handler implemented appropriately.

| | | | | | | | | | | | | | | | | | | | | | | | | | | On the majority of 85xx & 86xx we have a register that's ability to assert HRESET_REQ to reset the board.

With the previous code it was possible to match on pci bridges since we were only matching on device_type. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. PCI and reset are factored out into pq2.c. I renamed them from m82xx to pq2 because they won't work on the Integrated Host Processor line of 82xx chips (i.e. 8240, 8245, and such). 2. The PCI PIC, which is nominally board-specific, is used on multiple boards, and thus is used into pq2ads-pci-pic.c. 3. The new CPM binding is used. 4. General cleanup.

| * | [POWERPC] 8xx: Work around CPU15 erratum.Scott Wood2007-10-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The CPU15 erratum on MPC8xx chips can cause incorrect code execution under certain circumstances, where there is a conditional or indirect branch in the last word of a page, with a target in the last cache line of the next page. This patch implements one of the suggested workarounds, by forcing a TLB miss whenever execution crosses a page boundary. This is done by invalidating the pages before and after the one being loaded into the TLB in the ITLB miss handler.

Keep a global mpc8xx_immr mapping, rather than constantly creating temporary mappings. 2. Look for new fsl,cpm1 and fsl,cpm1-pic names. 3. Always reset the CPM when not using the udbg console; this is required in case the firmware initialized a device that is incompatible with one that the kernel is about to use. 4. Remove some superfluous casts and header includes. 5. Change a usage of IMAP_ADDR to get_immrbase(). 6. Use phys_addr_t, not uint, for dpram_pbase. 7. Various sparse-related fixes, such as __iomem annotations. 8. Remove mpc8xx_show_cpuinfo, which doesn't provide anything useful beyond the generic cpuinfo handler. 9.

Some of the changes include: 1. Proper namespace scoping for Freescale compatibles and properties. 2. Use compatible rather than things like device_type and model to determine which particular variant of a device is present. 3. Give the drivers the relevant CPM command word directly, rather than requiring it to have a lookup table based on device-id, SCC v. SMC, and CPM version. 4. Specify the CPCR and the usable DPRAM region in the CPM's reg property. Boards that do not require the legacy bindings should select CONFIG_PPC_CPM_NEW_BINDING to enable the of_platform CPM devices. Once all existing boards are converted and tested, the config option can become default y to prevent new boards from using the old model. Once arch/ppc is gone, the config option can be removed altogether.

That commit causes the mpsc's CON_PRINTBUFFER flag to be cleared since udbg should have printed the previous output. I guess we can no longer ignore udbg. :) This patch provides udbg_putc() and udbg_getc() functions for the Marvell mv64x60 chips. These functions are enabled if an mv64x60 port is to be used as the console as determined from the device tree. Signed-off-by: Dale Farnsworth <dale@farnsworth.org> Acked-by: Mark A.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds DEFINE_SPUFS_ATTRIBUTE(), a wrapper around DEFINE_SIMPLE_ATTRIBUTE which does the specified locking for the get routine for us. Unfortunately we need two get routines (a locked and unlocked version) to support the coredump code. This hides one of those (the locked version) inside the macro foo.

If we're coredumping to a pipe we can't trust file->f_pos, we need to maintain the foffset value passed to us. The cleanest way to do this is to have the low level write routine increment foffset when we've successfully written.
