* arch: Clean up asm/barrier.h implementations using asm-generic/barrier.hPeter Zijlstra2014-01-122-27/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We're going to be adding a few new barrier primitives, and in order to avoid endless duplication make more agressive use of asm-generic/barrier.h. Change the asm-generic/barrier.h such that it allows partial barrier definitions and fills out the rest with defaults. There are a few architectures (m32r, m68k) that could probably do away with their barrier.h file entirely but are kept for now due to their unconventional nop() implementation.

| | * | | of/irq: Rename of_irq_map_* functions to of_irq_parse_*Grant Likely2013-10-241-1/+1
| | |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The OF irq handling code has been overloading the term 'map' to refer to both parsing the data in the device tree and mapping it to the internal linux irq system. This is probably because the device tree does have the concept of an 'interrupt-map' function for translating interrupt references from one node to another, but 'map' is still confusing when the primary purpose of some of the functions are to parse the DT data. This patch renames all the of_irq_map_* functions to of_irq_parse_* which makes it clear that there is a difference between the parsing phase and the mapping phase. Kernel code can make use of just the parsing or just the mapping support as needed by the subsystem. The patch was generated mechanically with a handful of sed commands.

A bunch of bug fixes, particularly for initialization and some refactoring. Most notable change if feeding the entire flattened tree into the random pool at boot. May not be significant, but shouldn't hurt either" Tim Bird questions whether the boot time cost of the random feeding may be noticeable. And "add_device_randomness()" is definitely not some speed deamon of a function. * tag 'devicetree-for-linus' of git://git.secretlab.ca/git/linux: of/platform: add error reporting to of_amba_device_create() irq/of: Fix comment typo for irq_of_parse_and_map of: Feed entire flattened device tree into the random pool of/fdt: Clean up casting in unflattening path of/fdt: Remove duplicate memory clearing on FDT unflattening gpio: implement gpio-ranges binding document fix of: call __of_parse_phandle_with_args from of_parse_phandle of: introduce of_parse_phandle_with_fixed_args of: move of_parse_phandle() of: move documentation of of_parse_phandle_with_args of: Fix missing memory initialization on FDT unflattening of: consolidate definition of early_init_dt_alloc_memory_arch() of: Make of_get_phy_mode() return int i.s.o. const int include: dt-binding: input: create a DT header defining key codes. of/platform: Staticize of_platform_device_create_pdata() of: Specify initrd location using 64-bit dt: Typo fix OF: make of_property_for_each_{u32|string}() use parameters if OF is not enabled

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some PAE architectures, the entire range of physical memory could reside outside the 32-bit limit. These systems need the ability to specify the initrd location using 64-bit numbers. This patch globally modifies the early_init_dt_setup_initrd_arch() function to use 64-bit numbers instead of the current unsigned long. There has been quite a bit of debate about whether to use u64 or phys_addr_t. It was concluded to stick to u64 to be consistent with rest of the device tree code. As summarized by Geert, "The address to load the initrd is decided by the bootloader/user and set at that point later in time. The dtb should not be tied to the kernel you are booting" More details on the discussion can be found here: https://lkml.org/lkml/2013/6/20/690 https://lkml.org/lkml/2012/9/13/544 Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Acked-by: Rob Herring <rob.herring@calxeda.com> Acked-by: Vineet Gupta <vgupta@synopsys.com> Acked-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Grant Likely <grant.likely@linaro.org>
