2007-07-12[MIPS] SMTC: Interrupt mask backstop hackKevin D. Kissell
To support multiple TC microthreads acting as "CPUs" within a VPE, VPE-wide interrupt mask bits must be specially manipulated during interrupt handling. To support legacy drivers and interrupt controller management code, SMTC has a "backstop" to track and if necessary restore the interrupt mask. This has some performance impact on interrupt service overhead. Disable it only if you know what you are doing. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-07-12[ARM] pxa: move device registration into CPU-specific fileRussell King
This allows individual CPU support to determine which platform devices should be registered. Also fix a copy-n-paste bug in the I2C power platform device entry. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-12[ARM] pxa: remove boot time RTC initialisationRussell King
The RTC library code contains everything necessary to set the system time from the RTC; for similar reasons as the previous commit, it's far better to let the RTC library code sort this out rather than implement something which might not be appropriate for everyone. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-12[ARM] pxa: stop doing our own rtc management over suspendRussell King
Remove the RTC management over a suspend/resume cycle. Firstly, we may not be using the internal RTC for time keeping; some platforms have an external RTC for this inspite of the PXA having an internal RTC. Secondly, the RTC library code handles updating system time on resume. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-12[ARM] 4451/1: pxa: make dma.c generic and remove cpu specific dma codeEric Miao
Since the number of dma channels varies between pxa25x and pxa27x, it introduces some specific code in dma.c. This patch moves the specific code to pxa25x.c and pxa27x.c and makes dma.c more generic. 1. add pxa_init_dma() for dma initialization, the number of channels are passed in by the argument 2. add a "prio" field to the "struct pxa_dma_channel" for the channel priority, and is initialized in pxa_init_dma() 3. use a general priority comparison with the channels "prio" field so to remove the processor specific pxa_for_each_dma_prio macro, this is not lightning fast as the original one, but it is acceptable as it happens when requesting dma, which is usually not so performance critical Signed-off-by: eric miao <eric.miao@marvell.com> Acked-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-12[ARM] 4450/1: pxa: add pxa25x_init_irq() and pxa27x_init_irq()Eric Miao
/* should be ok this time, I aligned this patch to your arm:pxa2.mbox */ 1. move pxa25x specific IRQ initialization code to pxa25x_init_irq() and pxa27x code to pxa27x_init_irq(), remove pxa_init_irq() 2. replace all pxa_init_irq() with their PXA25x or PXA27x specific functions Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-12[ARM] 4438/1: PXA: remove #ifdef .. #endif from pxa_gpio_demux_handler()Eric Miao
1. use GPIO_IRQ_mask[] to select those bits of interest, actually only those "unmasked" GPIO IRQs with their corresponding bits in GPIO_IRQ_mask[] set to "1" should be checked 2. remove #ifdef PXA_LAST_GPIO > 96 .. #endif, GPIO_IRQ_mask[] is used to mask out the irrelevant bits, so that even though the GEDR3 on PXA25x is reserved, it will be masked, and the following code will never run. Another point is that GPIO85- GPIO95 bits within GEDR2 will also be masked out on PXA25x Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-12[ARM] 4437/1: PXA: move the GPIO IRQ initialization code to pxa_init_irq_gpio()Eric Miao

2007-07-12[ARM] 4436/1: PXA: move low IRQ initialization code to pxa_init_irq_low()Eric Miao
1. move low IRQ initialization code to pxa_init_irq_low() Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-12[ARM] 4435/1: PXA: remove PXA_INTERNAL_IRQSEric Miao
1. define PXA_GPIO_IRQ_BASE to be right after the internal IRQs, and define PXA_GPIO_IRQ_NUM to be 128 for all PXA2xx variants 2. make the code specific to the high IRQ numbers (32..64) to be PXA27x specific 3. add a function pxa_init_irq_high() to initialize the internal high IRQ chip, the invoke of this function could be moved to PXA27x specific initialization code Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-12[ARM] 4434/1: PXA: remove PXA_IRQ_SKIPEric Miao
1. PXA_IRQ_SKIP is defined to be 7 on PXA25x so that the first IRQ starts from zero. This makes IRQ numbering inconsistent between PXA25x and PXA27x. Remove this macro so that the same IRQ_XXXXX definition has the same value on both PXA25x and PXA27x. 2. make IRQ_SSP3..IRQ_PWRI2C valid only if PXA27x is defined, this avoids unintentional use of these macros on PXA25x Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-12[ARM] pxa: Fix PXA27x suspend type validation, remove pxa_pm_prepare()Russell King
pxa_pm_prepare() tried to validate the suspend method type. As noted in previous commits: eb9289eb20df6b54214c45ac7c6bf5179a149026 9c372d06ce9ddf65e1393f9ea22a6d6bd5f96b42 e8c9c502690efd24b7055bf608e7a3c34216848b the checking of the suspend type in the 'prepare' method is the wrong place to do this; use the 'valid' method instead. This means that pxa_pm_prepare() can be entirely removed. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-12[ARM] pxa: move pm_ops structure into CPU specific filesRussell King
Move the pm_ops structure into the PXA25x and PXA27x support files. Remove the old pxa_pm_prepare() function, and rename the both pxa_cpu_pm_prepare() functions as pxa_pm_prepare(). We'll fix that later. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-07-12[ARM] pxa: remove useless pxa_pm_finish() functionRussell King
pxa_pm_finish() does nothing but return zero. The core code does nothing with this return value, and will not try to call the finish method in the pm_ops structure if it is NULL. Therefore, we can remove this useless function. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-12[ARM] 4453/1: Fully Decode ARM instruction set state in show_regs() tombstoneGeorge G. Davis
The ARM show_regs() tombstone only partially decodes which ARM ISA was executing at the time a fault occurred displaying either "(T)" for the Thumb case or nothing at all for other cases. This patch therefore explicitly identifies which state the processor is in at the time of a fault: ARM, Thumb, Jazelle or JazelleEE. Signed-off-by: George G.

2007-07-12[ARM] 4393/2: ARMv7: Add uncompressing code for the new CPU Id formatCatalin Marinas

2007-07-12[ARM] riscpc: fix decompressor font file handlingRussell King
font_acorn_8x8.o was being built in drivers/video/console/ twice during a build _in the same location_ - once for the kernel proper, and once for the decompressor. The result is when you came to run an install target, the kernel was always rebuilt due to this file apparantly having been built with different compiler arguments. Solve this by making a local copy at build time in the decompressor's directory. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-07-12[ARM] 4407/1: Remove in-kernel mach id setting for gtwx5715 ixp4xx boardMichael-Luke Jones
If MACH_GTWX5715 is set in Kconfig, this code sets the mach id automatically. Howeber, this means that any IXP4xx kernel which is setup to support the gtwx5715 board will not successfully boot on any other board. If the bootloader sets the wrong mach id, it should be set correctly by a kernel shim. Signed-off-by: Michael-Luke Jones <mlj28@cam.ac.uk> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-12[ARM] 4408/2: Fixup support for gtwx5715 ixp4xx boardMichael-Luke Jones
This patch fixes up compiling of the gtwx5715 board setup code, which has apparently been broken since 2.6.18 and the generic IRQ changes. In addition it removes some unecessary extern declarations in the gtwx5715-pci.c file. Signed-off-by: Michael-Luke Jones <mlj28@cam.ac.uk> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-07-12[ARM] 4373/1: i.MX/MX1 GPIO support implementationPavel Pisa
Support for generic input output for MX1 family. The implementation prevents allocation of one pin by two users, but does not store pointer to the user description permanently, because this solution would have bigger memory overhead. The simple way to integrate code with per BSP pins setup and allocation is required else all GPIO registration checking is useless. The function imx_gpio_setup_multiple_pins() can be used for this purpose in future. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Add support for the partition layour used on the revision B modules which ship with large page NAND flash as default. The differnce between the old and new layouts is that the large page devices use 128KiB blocks, so the initial loader partition now ends at 128KiB boundary pushing the begining of partition 1 up.
