2009-05-30Add core support for ARMv6/v7 big-endianCatalin Marinas
Starting with ARMv6, the CPUs support the BE-8 variant of big-endian (byte-invariant). This patch adds the core support: - setting of the BE-8 mode via the CPSR.E register for both kernel and user threads - big-endian page table walking - REV used to rotate instructions read from memory during fault processing as they are still little-endian format - Kconfig and Makefile support for BE-8. The --be8 option must be passed to the final linking stage to convert the instructions to little-endian Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>

2009-03-23[ARM] pxa: add base support for Marvell's PXA168 processor lineEric Miao
"""The Marvell® PXA168 processor is the first in a family of application processors targeted at mass market opportunities in computing and consumer devices. It balances high computing and multimedia performance with low power consumption to support extended battery life, and includes a wealth of integrated peripherals to reduce overall BOM cost .... """ See http://www.marvell.com/featured/pxa168.jsp for more information. 1. Marvell Mohawk core is a hybrid of xscale3 and its own ARM core, there are many enhancements like instructions for flushing the whole D-cache, and so on 2. Clock reuses Russell's common clkdev, and added the basic support for UART1/2. 3. Devices are a bit different from the 'mach-pxa' way, the platform devices are now dynamically allocated only when necessary (i.e. when pxa_register_device() is called). Description for each device are stored in an array of 'struct pxa_device_desc'. Now that: a. this array of device description is marked with __initdata and can be freed up system is fully up b. which means board code has to add all needed devices early in his initializing function c. platform specific data can now be marked as __initdata since they are allocated and copied by platform_device_add_data() 4. only the basic UART1/2/3 are added, more devices will come later.

2008-07-28[ARM] pxa: add support for L2 outer cache on XScale3 (attempt 2)Eric Miao
(20072fd0c93349e19527dd2fa9588b4335960e62 lost most of its changes somehow, came from a mbox archive applied with git-am. No idea what happened. This puts back the missing bits. --rmk) The initial patch from Lothar, and Lennert make it into a cleaner one, modified and tested on PXA320 by Eric Miao. This patch moves the L2 cache operations out of proc-xsc3.S into dedicated outer cache support code. CACHE_XSC3L2 can be deselected so no L2 cache specific code will be linked in, and that L2 enable bit will not be set, this applies to the following cases: a. _only_ PXA300/PXA310 support included and no L2 cache wanted b. PXA320 support included, but want L2 be disabled So the enabling of L2 depends on two things: - CACHE_XSC3L2 is selected - and L2 cache is present Where the latter is only a safeguard (previous testing shows it works OK even when this bit is turned on). IXP series of processors with XScale3 cannot disable L2 cache for the moment since they depend on the L2 cache for its coherent memory, so IXP may always select CACHE_XSC3L2. Other L2 relevant bits are always turned on (i.e. the original code enclosed by #if L2_CACHE_ENABLED .. #endif), as they showed no side effects. Specifically, these bits are: - OC bits in TTBASE register (table walk outer cache attributes) - LLR Outer Cache Attributes (OC) in Auxiliary Control Register Signed-off-by: Lothar WaÃ<9f>mann <LW@KARO-electronics.de> Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: Eric Miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2008-06-22[ARM] Feroceon: L2 cache supportLennert Buytenhek
This patch adds support for the unified Feroceon L2 cache controller as found in e.g. the Marvell Kirkwood and Marvell Discovery Duo families of ARM SoCs. Note that: - Page table walks are outer uncacheable on Kirkwood and Discovery Duo, since the ARMv5 spec provides no way to indicate outer cacheability of page table walks (specifying it in TTBR[4:3] is an ARMv6+ feature). This requires adding L2 cache clean instructions to proc-feroceon.S (dcache_clean_area(), set_pte()) as well as to tlbflush.h ({flush,clean}_pmd_entry()). The latter case is handled by defining a new TLB type (TLB_FEROCEON) which is almost identical to the v4wbi one but provides a TLB_L2CLEAN_FR flag. - The Feroceon L2 cache controller supports L2 range (i.e. 'clean L2 range by MVA' and 'invalidate L2 range by MVA') operations, and this patch uses those range operations for all Linux outer cache operations, as they are faster than the regular per-line operations. L2 range operations are not interruptible on this hardware, which avoids potential livelock issues, but can be bad for interrupt latency, so there is a compile-time tunable (MAX_RANGE_SIZE) which allows you to select the maximum range size to operate on at once. (Valid range is between one cache line and one 4KiB page, and must be a multiple of the line size.) Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>

This patch adds support for the Marvell LB88RC8480 Development Board, enabling the use of the PCIe interfaces, the ethernet interfaces, the TWSI interfaces and the UARTs.

2007-07-22[ARM] 4461/1: MXC platform and i.MX31ADS core supportQuinn Jensen
This patch adds the foundation pieces for the Freescale MXC platforms, including i.MX2 and i.MX3 based systems. The bare-bones MX31 support in this patch boots to the rootdev panic with 8250 serial console configured "console=ttyS0,115200". It assumes that Redboot is the boot loader.

2007-07-20[ARM] 4497/1: Only allow safe cache configurations on ARMv6 and laterCatalin Marinas
Currently, Linux doesn't generate correct page tables for ARMv6 and later cores if the cache policy is different from the default one (it may lead to strongly ordered or shared device mappings). This patch disallows cache policies other than writeback and the CPU_[ID]CACHE_DISABLE options only affect the CP15 system control register rather than the page tables.
