2011-09-17ARM: 7091/1: errata: D-cache line maintenance operation by MVA may not succeedWill Deacon
This patch implements a workaround for erratum 764369 affecting Cortex-A9 MPCore with two or more processors (all current revisions). Under certain timing circumstances, a data cache line maintenance operation by MVA targeting an Inner Shareable memory region may fail to proceed up to either the Point of Coherency or to the Point of Unification of the system. This workaround adds a DSB instruction before the relevant cache maintenance functions and sets a specific bit in the diagnostic control register of the SCU.

2011-09-14ARM: zImage: allow supplementing appended DTB with traditional ATAG dataNicolas Pitre
Some old bootloaders can't be updated to a device tree capable one, yet they provide ATAGs with memory configuration, the ramdisk address, the kernel cmdline string, etc. To allow a device tree enabled kernel to be used with such bootloaders, it is necessary to convert those ATAGs into FDT properties and fold them into the DTB appended to zImage. Currently the following ATAGs are converted: ATAG_CMDLINE ATAG_MEM ATAG_INITRD2 If the corresponding information already exists in the appended DTB, it is replaced, otherwise the required node is created to hold it. The code looks for ATAGs at the location pointed by the value of r2 upon entry into the zImage code. If no ATAGs are found there, an attempt at finding ATAGs at the typical 0x100 offset from start of RAM is made. Otherwise the DTB is left unchanged.

2011-09-08ARM: 7083/1: rewrite U300 GPIO to use gpiolibLinus Walleij
This rewrites the U300 GPIO so as to use gpiolib and struct gpio_chip instead of just generic GPIO, hiding all the platform specifics and passing in GPIO chip variant as platform data at runtime instead of the compiletime kludges. As a result <mach/gpio.h> is now empty for U300 and using just defaults.

2011-07-28irq: add irq_domain translation infrastructureGrant Likely
This patch adds irq_domain infrastructure for translating from hardware irq numbers to linux irqs. This is particularly important for architectures adding device tree support because the current implementation (excluding PowerPC and SPARC) cannot handle translation for more than a single interrupt controller. irq_domain supports device tree translation for any number of interrupt controllers. This patch converts x86, Microblaze, ARM and MIPS to use irq_domain for device tree irq translation. x86 is untested beyond compiling it, irq_domain is enabled for MIPS and Microblaze, but the old behaviour is preserved until the core code is modified to actually register an irq_domain yet. On ARM it works and is required for much of the new ARM device tree board support. PowerPC has /not/ been converted to use this new infrastructure. It is still missing some features before it can replace the virq infrastructure already in powerpc (see documentation on irq_domain_map/unmap for details). Followup patches will add the missing pieces and migrate PowerPC to use irq_domain. SPARC has its own method of managing interrupts from the device tree and is unaffected by this change.

It means omap_readl() inside these helper functions does not appear in ftrace output. Another plus is that we avoid the overhead of calculating the address to read each time, but a minus is that we use readl() which has a barrier.

2011-06-29ARM: 6886/1: mmc, Add zboot from eSD support for SuperH Mobile ARMSimon Horman
This allows a ROM-able zImage to be written to eSD and for SuperH Mobile ARM to boot directly from the SDHI hardware block. This is achieved by the MaskROM loading the first portion of the image into MERAM and then jumping to it. This portion contains loader code which copies the entire image to SDRAM and jumps to it. From there the zImage boot code proceeds as normal, uncompressing the image into its final location and then jumping to it.
