2010-02-27MIPS: Alchemy: devboards: wire up new PCMCIA driver.Manuel Lauss
Register the PCMCIA driver on all boards supported by it, get rid of now-unused pcmcia macros in the board headers (and subsequently empty pb1100/pb1500 ones). Signed-off-by: Manuel Lauss <manuel.lauss@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2010-02-27MIPS: PCMCIA: new socket driver for Au1000 demoboards.Manuel Lauss
New PCMCIA socket driver for all Db/Pb1xxx boards (except Pb1000), which replaces au1000_db1x00.c and (most of) au1000_pb1x00.c. Notable improvements: - supports Db1000, DB/PB1100/1500/1550/1200. - support for carddetect and statuschange IRQs. - pcmcia socket mem/io/attr areas and irqs passed through platform resource information. - doesn't freeze system during card insertion/ejection like the one it replaces. - boardtype is automatically detected using BCSR ID register. Run-tested on the DB1200. Cc: Linux-PCMCIA <linux-pcmcia@lists.infradead.org> Signed-off-by: Manuel Lauss <manuel.lauss@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2010-02-27MIPS: Alchemy: remove board_init_irq() function.Manuel Lauss
remove board_init_irq(): On all in-kernel boards it is sufficient to initialize board interrupts in an arch_initcall by using the default linux irq functions. Some small irqmap.c files have been folded into board_setup files. Run-tested on DB1200; compile-tested on all other affected boards.

2010-02-27MIPS: Alchemy: devboard register abstractionManuel Lauss
All Alchemy development boards have external CPLDs with a few registers in them. They all share an identical register layout with only a few minor differences (except the PB1000) in bit functions and base addresses. This patch - adds a primitive facility to initialize and use these external registers, - replaces all occurrences of bcsr->xxx accesses with calls to the new functions (the pb1200 cascade irq handling code is special). - collects BCSR register information scattered throughout the board headers in a central place.

2010-02-01MIPS: Alchemy: Fix dbdma ring destruction memory debugcheck.Manuel Lauss
DBDMA descriptors need to be located at 32-byte aligned addresses; however kmalloc in conjunction with the SLAB allocator and CONFIG_DEBUG_SLUB enabled doesn't deliver any. The dbdma code works around that by allocating a larger area and realigning the start address within it. When freeing a channel however this adjustment is not taken into account which results in an oops: Kernel bug detected[#1]: [...] Call Trace: [<80186010>] cache_free_debugcheck+0x284/0x318 [<801869d8>] kfree+0xe8/0x2a0 [<8010b31c>] au1xxx_dbdma_chan_free+0x2c/0x7c [<80388dc8>] au1x_pcm_dbdma_free+0x34/0x4c [<80388fa8>] au1xpsc_pcm_close+0x28/0x38 [<80383cb8>] soc_codec_close+0x14c/0x1cc [<8036dbb4>] snd_pcm_release_substream+0x60/0xac [<8036dc40>] snd_pcm_release+0x40/0xa0 [<8018c7a8>] __fput+0x11c/0x228 [<80188f60>] filp_close+0x7c/0x98 [<80189018>] sys_close+0x9c/0xe4 [<801022a0>] stack_done+0x20/0x3c Fix this by recording the address delivered by kmalloc() and using it as parameter to kfree(). This fix is only necessary with the SLAB allocator and CONFIG_DEBUG_SLAB enabled; non-debug SLAB, SLUB do return nicely aligned addresses, debug-enabled SLUB currently panics early in the boot process.

2010-01-28MIPS: PowerTV: Fix support for timer interrupts with > 64 external IRQsDavid VomLehn
The MIPS processor is limited to 64 external interrupt sources. Using a greater number without IRQ sharing requires reading platform-specific registers. On such platforms, reading the IntCtl register to determine which interrupt corresponds to a timer interrupt will not work. On MIPSR2 systems there is a solution - the TI bit in the Cause register, specifically indicates that a timer interrupt has occured. This patch uses that bit to detect interrupts for MIPSR2 processors, which may be expected to work regardless of how the timer interrupt may be routed in the hardware.

2010-01-28MIPS: Fix vmlinuz build for 32bit-only math shellsAlexander Clouter
POSIX requires $((<expression>)) arithmetic in sh only to have long arithmetic so on 32-bit sh binaries might do only 32-bit arithmetic but the arithmetic done in arch/mips/boot/compressed/Makefile needs 64-bit. I play with the AR7 platform, so VMLINUX_LOAD_ADDRESS is 0xffffffff94100000, and for an example 4MiB kernel VMLINUZ_LOAD_ADDRESS is made out to be: ---- alex@berk:~$ bash -c 'printf "%x\n" $((0xffffffff94100000 + 0x400000))' ffffffff94500000 alex@berk:~$ dash -c 'printf "%x\n" $((0xffffffff94100000 + 0x400000))' 80000000003fffff ---- The former is obviously correct whilst the later breaks things royally. Fortunately working with only the lower 32bit's works for both bash and dash: ---- $ bash -c 'printf "%x\n" $((0x94100000 + 0x400000))' 94500000 $ dash -c 'printf "%x\n" $((0x94100000 + 0x400000))' 94500000 ---- So, we can split the original 64bit string to two parts, and only calculate the low 32bit part, which is big enough (1GiB kernel sizes anyone?) for a normal Linux kernel image file, now, we calculate the VMLINUZ_LOAD_ADDRESS like this: 1. if present, append top 32bit of VMLINUX_LOAD_ADDRESS" as a prefix 2. get the sum of the low 32bit of VMLINUX_LOAD_ADDRESS + VMLINUX_SIZE This patch fixes vmlinuz kernel builds on systems where only a 32bit-only math shell is available. Patch Changelog: Version 2 - simplified method by using 'expr' for 'substr' and making it work with dash once again Version 1 - Revert the removals of '-n "$(VMLINUX_SIZE)"' to avoid the error of "make clean" - Consider more cases of the VMLINUX_LOAD_ADDRESS Version 0 - initial release Signed-off-by: Alexander Clouter <alex@digriz.org.uk> Acked-by: Wu Zhangjin <wuzhangjin@gmail.com> Patchwork: http://patchwork.linux-mips.org/patch/861/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
