2013-03-19sf: Enable FDT-based configuration and memory mappingSimon Glass
Enable device tree control of SPI flash, and use this to implement memory-mapped SPI flash, which is supported on Intel chips. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-19fdt: Add fdtdec_get_addr_size() to read reg propertiesSimon Glass
It is common to have a "reg = <address size>" property in the FDT. Add a function to handle this, similar to the existing fdtdec_get_addr(); Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-18Merge branch 'master' of git://git.denx.de/u-boot-armTom Rini
Albert's rework of the linker scripts conflicted with Simon's making everyone use __bss_end. We also had a minor conflict over README.scrapyard being added to in mainline and enhanced in u-boot-arm/master with proper formatting.

2013-03-15Introduce a basic initcall implementationSimon Glass
This library supports calling a list of functions one after the other. It is intended that we move to a more powerful initcall implementation as proposed by Graeme Russ <graeme.russ@gmail.com>. For now, this allows us to do the basics. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-14Tegra30: mmc: Add Tegra30 SDMMC compatible entry to fdtdec & driverTom Warren
Tegra30 SD/MMC controller differs enough from Tegra20 that it needs its own entry in the compat_names/compat_id tables and in the Tegra MMC driver. Signed-off-by: Tom Warren <twarren@nvidia.com> Reviewed-by: Stephen Warren <swarren@nvidia.com>
2013-03-14Tegra: MMC: Add DT support to MMC driver for all T20 boardsTom Warren
tegra_mmc_init() now parses the DT info for bus width, WP/CD GPIOs, etc. Tested on Seaboard, fully functional. Tamonten boards (medcom-wide, plutux, and tec) use a different/new dtsi file w/common settings.

2013-03-14Tegra: I2C: Add T114 clock support to tegra_i2c driverTom Warren
T114 has a slightly different I2C clock, with a new (extra) divisor in standard/fast mode and HS mode. Tested on my Dalmore, and the I2C clock is 100KHz +/- 3Hz on my Saleae Logic analyzer. Added a new entry in compat_names for T114 I2C since it differs from the previous Tegra SoCs. A flag is set when T114 I2C HW is found so new features like the extra clock divisor can be used.

2013-03-11display_options:print_buffer: align ASCII printAndreas Bießmann
This patch adds whitespace to the printed hex numbers to have an aligned ASCII printout at the end of the line. This changes for example the md output from: ---8<--- OMAP3 Tricorder # md.l $loadaddr 5 82000000: 30200109 20a4028c 90010000 08a00000 .. 0... ........ 82000010: 01010000 .... --->8--- to ---8<--- OMAP3 Tricorder # md.l $loadaddr 5 82000000: 30200109 20a4028c 90010000 08a00000 .. 0... ........ 82000010: 01010000 .... --->8--- The cost of this is about 72 byte .text increase (tested with at91 build).

2013-02-28Roll crc32 into hash infrastructureSimon Glass
Add the CRC32 algorithm to the list of available hashes, and make the crc32 command use hash_command(). Add a new crc32_wd_buf() to make this possible, which puts its result in a buffer rather than returning it as a 32-bit value. Note: For some boards the hash command is not enabled, neither are sha1, sha256 or the verify option. In this case the full hash implementation adds about 500 bytes of overhead. So as a special case, we use #ifdef to select very simple bahaviour in that case. The justification for this is that it is currently a very common case (virtually all boards enable crc32 but only some enable more advanced features). Signed-off-by: Simon Glass <sjg@chromium.org>
2013-02-28Update print_buffer() to use constSimon Glass
The buffer cannot be changed by this function, so change the buffer pointer to a const. This allows callers with const pointer to use the function without a cast. Signed-off-by: Simon Glass <sjg@chromium.org>

2013-02-11tegra: add SPI SLINK driverAllen Martin
Add driver for tegra SPI "SLINK" style driver. This controller is similar to the tegra20 SPI "SFLASH" controller. The difference is that the SLINK controller is a genernal purpose SPI controller and the SFLASH controller is special purpose and can only talk to FLASH devices. In addition there are potentially many instances of an SLINK controller on tegra and only a single instance of SFLASH. Tegra20 is currently ths only version of tegra that instantiates an SFLASH controller. This driver supports basic PIO mode of operation and is configurable (CONFIG_OF_CONTROL) to be driven off devicetree bindings. Up to 4 devices per controller may be attached, although typically only a single chip select line is exposed from tegra per controller so in reality this is usually limited to 1. To enable this driver, use CONFIG_TEGRA_SLINK Signed-off-by: Allen Martin <amartin@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
2013-02-11tegra: spi: add fdt support to tegra SPI SFLASH driverAllen Martin

2013-01-08arm: move C runtime setup code in crt0.SAlbert ARIBAUD
Move all the C runtime setup code from every start.S in arch/arm into arch/arm/lib/crt0.S. This covers the code sequence from setting up the initial stack to calling into board_init_r(). Also, rewrite the C runtime setup and make functions board_init_*() and relocate_code() behave according to normal C semantics (no jumping across the C stack any more, etc). Some SPL targets had to be touched because they use start.S explicitly or for some reason; the relevant maintainers and custodians are cc:ed. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>

2012-12-13env: Add environment variable flagsJoe Hershberger
Currently just validates variable types as decimal, hexidecimal, boolean, ip address, and mac address. If the entry is not found in the env ".flags", then look in the static one. This allows the env to override the static definitions, but prevents the need to have every definition in the environment distracting you. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>

2012-12-13env: Hide '.' variables in env print by defaultJoe Hershberger
When printing all variables with env print, don't print variables that begin with '.'. If env print is called with a '-a' switch, then include variables that begin with '.' (just like the ls command). Variables printed explicitly will be printed even without the -a. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
2012-12-13env: Refactor apply into change_okJoe Hershberger
Move the read of the old value to inside the check function. In some cases it can be avoided all together and at the least the code is only called from one place. Also name the function and the callback to more clearly describe what it does. Pass the ENTRY instead of just the name for direct access to the whole data structure. Pass an enum to the callback that specifies the operation being approved. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>

2012-12-13Make linux kernel string funcs available to toolsJoe Hershberger
isspace() and strim() are not in the typical user-mode string.h, so put them in a separate compilation unit so that they can be built into tools that need them independent of the other common string functions. This allows code shared by u-boot and the linux user-mode tools to link. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
2012-12-13vsprintf:fix: Change type returned by ustrtoulLukasz Majewski

2012-12-11Add strcasecmp() and strncasecmp()Simon Glass
strncasecmp() is present as strnicmp() but disabled. Make it available and define strcasecmp() also. There is a only a small performance penalty to having strcasecmp() call strncasecmp(), so do this instead of a standalone function, to save code space. Update the prototype in arch-specific headers as needed to avoid warnings. Signed-off-by: Simon Glass <sjg@chromium.org>
