2008-09-09MX2: Add DMA support for mx2 and (eventually) mx1Sascha Hauer
This patch adds DMA support for Freescale i.MX27 SoCs. It is derived from the i.MX1 port and should (though currently untested) still be working for the i.MX1. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2008-09-09i.MX: Add FIQ supportPaulius Zaleckas
Drivers which are going to use it will have to select it and use imx_set_irq_fiq() to set FIQ mode for this interrupt. Changes since V1: - removed '#ifdef CONFIG_FIQ' from irqs.h - renamed imx_set_irq_type() to imx_set_irq_fiq() - made irqt unsigned - fixed irq number check Signed-off-by: Paulius Zaleckas <paulius.zaleckas@teltonika.lt> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

2008-09-06[ARM] 5241/1: provide ioremap_wc()Lennert Buytenhek
This patch provides an ARM implementation of ioremap_wc(). We use different page table attributes depending on which CPU we are running on: - Non-XScale ARMv5 and earlier systems: The ARMv5 ARM documents four possible mapping types (CB=00/01/10/11). We can't use any of the cached memory types (CB=10/11), since that breaks coherency with peripheral devices. Both CB=00 and CB=01 are suitable for _wc, and CB=01 (Uncached/Buffered) allows the hardware more freedom than CB=00, so we'll use that. (The ARMv5 ARM seems to suggest that CB=01 is allowed to delay stores but isn't allowed to merge them, but there is no other mapping type we can use that allows the hardware to delay and merge stores, so we'll go with CB=01.) - XScale v1/v2 (ARMv5): same as the ARMv5 case above, with the slight difference that on these platforms, CB=01 actually _does_ allow merging stores. (If you want noncoalescing bufferable behavior on Xscale v1/v2, you need to use XCB=101.) - Xscale v3 (ARMv5) and ARMv6+: on these systems, we use TEXCB=00100 mappings (Inner/Outer Uncacheable in xsc3 parlance, Uncached Normal in ARMv6 parlance). The ARMv6 ARM explicitly says that any accesses to Normal memory can be merged, which makes Normal memory more suitable for _wc mappings than Device or Strongly Ordered memory, as the latter two mapping types are guaranteed to maintain transaction number, size and order. We use the Uncached variety of Normal mappings for the same reason that we can't use C=1 mappings on ARMv5. The xsc3 Architecture Specification documents TEXCB=00100 as being Uncacheable and allowing coalescing of writes, which is also just what we need.

2008-09-05Revert "[ARM] use the new byteorder headers"David Woodhouse
This reverts commit ae82cbfc8beaa69007aa09966d3983ac938c3577. It needs the new byteorder headers to be exported to userspace, and they aren't yet -- and probably shouldn't be, at this point in the 2.6.27 release cycle (or ever, for that matter).

2008-08-27[ARM] Skip memory holes in FLATMEM when reading /proc/pagetypeinfoMel Gorman
Ordinarily, memory holes in flatmem still have a valid memmap and is safe to use. However, an architecture (ARM) frees up the memmap backing memory holes on the assumption it is never used. /proc/pagetypeinfo reads the whole range of pages in a zone believing that the memmap is valid and that pfn_valid will return false if it is not. On ARM, freeing the memmap breaks the page->zone linkages even though pfn_valid() returns true and the kernel can oops shortly afterwards due to accessing a bogus struct zone *. This patch lets architectures say when FLATMEM can have holes in the memmap. Rather than an expensive check for valid memory, /proc/pagetypeinfo will confirm that the page linkages are still valid by checking page->zone is still the expected zone. The lookup of page_zone is safe as there is a limited range of memory that is accessed when calling page_zone. Even if page_zone happens to return the correct zone, the impact is that the counters in /proc/pagetypeinfo are slightly off but fragmentation monitoring is unlikely to be relevant on an embedded system.
