2014-04-22fdt_support: Add helper function to read "ranges" propertyAlexander Graf
This patch adds a helper function that can be used to interpret most "ranges" properties in the device tree. It reads the n'th range out of a "ranges" array and returns the node's virtual address of the range, the physical address that range starts at and the size of the range.

2014-04-22fdt_support: split fdt_getprop_u32_defaultAlexander Graf
We already have a nice helper to give us a property cell value with default fall back from a path. Split that into two helpers - one for the old path based lookup and one to give us a value based on a node offset.

2014-04-18blackfin: make name_to_gpio be a weak symbolIan Campbell
This required moving it into a C file from the header. The only user of a non-default name_to_gpio is blackfin, therefore build tested with the blackfin bct-brettl2 build, which is one I picked at random. Also tested with a build for the ARM tec board which uses the default/fallback implementation. Inspection with objdump shows that both have done the right thing. This change was requested by Marek during review of the sunxi patch series.

2014-03-24mmc: Split mmc struct, rework mmc initialization (v2)Pantelis Antoniou
The way that struct mmc was implemented was a bit of a mess; configuration and internal state all jumbled up in a single structure. On top of that the way initialization is done with mmc_register leads to a lot of duplicated code in drivers. Typically the initialization got something like this in every driver. struct mmc *mmc = malloc(sizeof(struct mmc)); memset(mmc, 0, sizeof(struct mmc); /* fill in fields of mmc struct */ /* store private data pointer */ mmc_register(mmc); By using the new mmc_create call one just passes an mmc config struct and an optional private data pointer like this: struct mmc = mmc_create(&cfg, priv); All in tree drivers have been updated to the new form, and expect mmc_register to go away before long. Changes since v1: * Use calloc instead of manually calling memset. * Mark mmc_register as deprecated. Signed-off-by: Pantelis Antoniou <panto@antoniou-consulting.com>

2014-03-07hush: fix some quoted variable expansion issuesStephen Warren
The following shell command fails: if test -z "$x"; then echo "zero"; else echo "non-zero"; fi (assuming $x does not exist, it prints "non-zero" rather than "zero"). ... since "$x" expands to nothing, and the argument is completely dropped, causing too few to be passed to -z, causing cmd_test() to error out early. This is because when variable expansions are processed by make_string(), the expanded results are concatenated back into a new string. However, no quoting is applied when doing so, so any empty variables simply don't generate any parameter when the combined string is parsed again. Fix this by explicitly replacing quoting any argument that was originally quoted when re-generating a string from the already-parsed argument list. This also fixes loss of whitespace in commands such as: setenv space " " setenv var " 1${space}${space} 2 " echo ">>${var}<<" Reported-by: Russell King <linux@arm.linux.org.uk> Acked-by: Simon Glass <sjg@chromium.org> Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>

2014-02-26arm: Switch to -mno-unaligned-access when supported by the compilerTom Rini
When we tell the compiler to optimize for ARMv7 (and ARMv6 for that matter) it assumes a default of SCTRL.A being cleared and unaligned accesses being allowed and fast at the hardware level. We set this bit and must pass along -mno-unaligned-access so that the compiler will still breakdown accesses and not trigger a data abort. To better help understand the requirements of the project with respect to unaligned memory access, the Documentation/unaligned-memory-access.txt file has been added as doc/README.unaligned-memory-access.txt and is taken from the v3.14-rc1 tag of the kernel.
