Our _GLOBAL macro does a ".align 2" so the alignment is fine for 32 bit, but on 64 bit it is possible for it to end up only 4 byte aligned. I don't know if it matters, but it can't hurt to 8 byte align it. It also means that when we build with --emit_relocs, none of our 64 bit relocations are to misaligned places. Signed-off-by:

Add support for a simple tagged database in the PS3 flash rom os-area. The database allows the flash rom os-area to be shared between a bootloader and installed operating systems. The application ps3-flash-util or the library libps3-utils from the ps3-utils package can be used for userspace database operations. The latest ps3-utils package is available here: git://git.kernel.org/pub/scm/linux/kernel/git/geoff/ps3-utils.gitSigned-off-by:

This adds definitions for the Cell memory controller registers (at least some of them) for use by the EDAC driver for ECC error reporting. It also expose the said MIC as a platform device that can be used by the EDAC driver to match on. Signed-off-by:

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). Signed-off-by:

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:

Discussions with firmware architects have confirmed that the bit in the ibm,pa-features property that indicates support for cache-inhibited large (>= 64kB) page mappings does in fact mean that the hypervisor allows 64kB mappings to I/O devices. Thus we can now enable the code that tests that bit and sets our CPU_FTR_CI_LARGE_PAGE feature bit. Signed-off-by: -

The name field of of_platform_driver is just copied into the included device_driver. By not overriding an already initialised device_driver name, we can convert the drivers over time to stop using the of_platform_driver name. Also we were not copying the owner field from of_platform_driver, so do the same with it. Signed-off-by:

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. We refactored that code so it can be shared between both platforms into fsl_soc.c and removed all the duplication in each platform directory. Signed-off-by: -

On the Freescale embedded (83xx, 85xx, 86xx) and a few of the discrete bridges (mpc10x, tsi108) use the new for_each_compatible_node() or for_each_node_by_type() to provide more exact matching when looking for PHBs in the device tree. With the previous code it was possible to match on pci bridges since we were only matching on device_type. Signed-off-by: -

The CONFIG_FSL_BOOKE mmu setup code fails when CONFIG_HIGHMEM=y and the 3 fixed TLB entries cannot exactly map the lowmem size. Each TLB entry can map 4MB, 16MB, 64MB or 256MB, so the failure is observed when the kernel lowmem size is not equal to the sum of up to 3 of those values. Normally, memory is sized in nice numbers, but I observed this problem while testing a crash dump kernel. The failure can also be observed by artificially reducing the kernel's main memory via the mem= kernel command line parameter. This commit fixes the problem by setting __initial_memory_limit in adjust_total_lowmem(). Signed-off-by:

This patch makes numerous miscellaneous code improvements to the QE library. 1. Remove struct ucc_common and merge ucc_init_guemr() into ucc_set_type() (every caller of ucc_init_guemr() also calls ucc_set_type()). Modify all callers of ucc_set_type() accordingly. 2. Remove the unused enum ucc_pram_initial_offset. 3. Refactor qe_setbrg(), also implement work-around for errata QE_General4. 4. Several printk() calls were missing the terminating \n. 5. Add __iomem where needed, and change u16 to __be16 and u32 to __be32 where appropriate. 6. In ucc_slow_init() the RBASE and TBASE registers in the PRAM were programmed with the wrong value. 7. Add the protocol type to struct us_info and updated ucc_slow_init() to use it, instead of always programming QE_CR_PROTOCOL_UNSPECIFIED. 8. Rename ucc_slow_restart_x() to ucc_slow_restart_tx() 9. Add several macros in qe.h (mostly for slow UCC support, but also to standardize some naming convention) and remove several unused macros. 10. Update ucc_geth.c to use the new macros. 11. Add ucc_slow_info.protocol to specify which QE_CR_PROTOCOL_xxx protcol to use when initializing the UCC in ucc_slow_init(). 12. Rename ucc_slow_pram.rfcr to rbmr and ucc_slow_pram.tfcr to tbmr, since these are the real names of the registers. 13. Use the setbits, clrbits, and clrsetbits where appropriate. 14. Refactor ucc_set_qe_mux_rxtx(). 15. Remove all instances of 'volatile'. 16. Simplify get_cmxucr_reg(); 17. Replace qe_mux.cmxucrX with qe_mux.cmxucr[]. 18. Updated struct ucc_geth because struct ucc_fast is not padded any more. Signed-off-by:
