2007-05-05[ARM] mm 8: define mem_types table L1 bit 4 to be for ARMv6Russell King
Change the memory types table to define the L1 descriptor bit 4 to be in terms of the ARMv6 definition - execute never. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-04-21[ARM] mm 6: allow mem_types table to specify extended pte attributesRussell King
Add prot_pte_ext to the mem_types table to allow the extended pte attributes to be passed to set_pte_ext(), thereby permitting us to specify memory type information for the hardware PTE entries. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-04-21[ARM] mm 5: Use mem_types table in ioremapRussell King
We really want to be using the memory type table in ioremap, so we only have to do the CPU type fixups in one place. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-04-21[ARM] mm 4: make create_mapping() more conventionalRussell King
Rather than our three separate loops to setup mappings (by page mappings up to a section boundary, then section mappings, and the remainder by page mappings) convert this to a more conventional Linux style of a loop over each page table level. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-04-21[ARM] mm 3: separate out supersection mappings, avoid for <4GBRussell King
Catalin Marinas at ARM Ltd says: > The CPU architects in ARM intended supersections only as a way to map > addresses >= 4GB. Supersections are not mandated by the architecture > and there is no easy way to detect their hardware support at run-time > (other than checking for a specific core). From the analysis done in > ARM, there wasn't a clear performance gain by using supersections > rather than sections (no significant improvement in the TLB misses). Therefore, we should avoid using supersections unless there's a real need (iow, we're mapping addresses >= 4GB). This means that we can simplify create_mapping() a bit since we will only use supersection mappings for addresses >= 4GB, which means that the physical, virtual and length must be multiples of the supersection mapping size. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-04-21[ARM] mm 2: clean up create_mapping()Russell King
There's now no need to carry around each protection separately. Instead, pass around the pointer to the entry in the mem_types array which we're interested in. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-04-21[ARM] mm 1: Combine mem_type domain into prot_* at init timeRussell King
Rather than combining the domain for a particular memory type with the protection information each time we want to use it, do so when we fix up the mem_type array at initialisation time. Rename struct mem_types to be mem_type - each structure is one memory type description, not several. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-04-21[ARM] Remove needless linux/ptrace.h includesRussell King
Lots of places in arch/arm were needlessly including linux/ptrace.h, resumably because we used to pass a struct pt_regs to interrupt handlers. Now that we don't, all these ptrace.h includes are redundant. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-03-17[ARM] 4271/1: iop32x: fix ep80219 detection (support iq80219 platforms)Dan Williams
An iq80219 is a board with an iq31244 layout and an 80219 processor. It breaks the current assumption that all 80219 processors run on ep80219 platforms. This patch adds the "force_ep80219" option to the kernel to override boot loaders that have passed in the iq31244 id, and adds the MACHINE_START definition for ep80219.

This patch corrects an error when demuxing the DMA irq's DMA1 was used as a base and this should have been DMA0. Without this fix we do not process DMA0 irq's and the system effectively locks up in a loop trying the process the irq it never can.

2007-03-16[PATCH] gpio_direction_output() needs an initial valueDavid Brownell
It's been pointed out that output GPIOs should have an initial value, to avoid signal glitching ... among other things, it can be some time before a driver is ready. This patch corrects that oversight, fixing - documentation - platforms supporting the GPIO interface - users of that call (just one for now, others are pending) There's only one user of this call for now since most platforms are still using non-generic GPIO setup code, which in most cases already couples the initial value with its "set output mode" request. Note that most platforms are clear about the hardware letting the output value be set before the pin direction is changed, but the s3c241x docs are vague on that topic ... so those chips might not avoid the glitches.

2007-03-05[PATCH] add CONFIG_GENERIC_GPIODavid Brownell
Most drivers using GPIOs already know they are running on a system that supports the generic GPIO calls, because of other platform dependencies. But the generic GPIO-based LED and input button drivers can't know that. So this patch adds a Kconfig hook, GENERIC_GPIO, to mark the platforms where <asm/gpio.h> will do the right thing. Currently that's a bunch of ARMs, and AVR32; more are on the way. It also fixes a dependency bug for the gpio button input driver; it was wrong to start with, now it covers all platforms with GENERIC_GPIO.
