Merge branch 'master' of git://git.denx.de/u-boot-arm
* 'master' of git://git.denx.de/u-boot-arm: (145 commits) beagleboard: enable HUB power on all variants of the BeagleBoard dm3730: enable dpll5 ehci-hcd: Allow cleanups to happen gracefully on a timeout. OMAP3: Add DSS driver for OMAP3 led: Remove state-saving of led for toggle functionality and add toggle option to led command led: Fixed setting of STATUS_LED_BIT1 when led_name is 'all' led: correct off/on locations in structure led: added cmd_led to Makefile BeagleBoard: fix LED 0/1 in driver Corrected LED name match finding avoiding extraneous Usage printouts BeagleBoard: config: updated default configuration BeagleBoard: config: Enabled multibus support for I2C in configuration BeagleBoard: config: add optargs/buddy/camera BeagleBoard: config: increase command-line functionality BeagleBoard: config: make mtest run BeagleBoard: config: enable DSS BeagleBoard: config: enable asix driver and dhcp BeagleBoard: config: enable networking BeagleBoard: config: decrease bootdelay to 2 seconds BeagleBoard: config: use uImage.beagle for tftp BeagleBoard: config: hardcode MAC for onboard SMSC BeagleBoard: config: load kernel from MMC ext, not FAT BeagleBoard: Configure DVI/S-video BeagleBoard: Added userbutton command BeagleBoard: turn off clocks in ehci_stop USB: Remove __attribute__ ((packed)) for struct ehci_hccr and ehci_hcor beagleboard: add support for xM revision C beagle: pass expansionboard name in bootargs OMAP: Remove omapfb.debug=y from Beagle and Overo env settings OMAP3 Beagle Pin Mux initialization glitch fix da850: modifications for Logic PD Rev.3 AM18xx EVM da850: fix the channel number for EMAC teardown init da850: add support for Spectrum Digital AM18xx EVM da850: add support to wake up DSP during board init da850: modify the U-Boot prompt string da850: add NOR boot mode support da8xx: add support for multiple PLL controllers da850: indicate cache usage disable in config file dm365: modify boot prompt from dm365 to dm36x dm365: disable cache usage due to coherency issues dm6446: disable cache usage due to coherency issues OMAP3: Remove legacy mmc driver devkit8000: Use generic MMC driver TI OMAP3 SDP3430: Use generic MMC driver AM3517 CraneBoard: Use generic MMC driver OMAP3: pandora: Use generic MMC driver OMAP3: Zoom2: Use generic MMC driver OMAP3: Zoom1: Use generic MMC driver OMAP3: DIG297: Use generic MMC driver OMAP3: CM-T35: Use generic MMC driver am3517evm: Use generic MMC driver omap3evm: Use generic MMC driver omap3:clock: check cpu_family before enabling clks for IVA & CAM omap3:clock: configure GFX clock to 200MHz for AM/DM37x OMAP3/4: Increase console I/O buffer size PXA: vpac270: Remove re-defined CONFIG_SYS_TEXT_BASE PXA: Fix CSB226, fix monitor length PXA: Fix Lubbock, remove redundant parenthesis armv7: cache: remove flush on un-aligned invalidate armv7: stronger barrier for cache-maintenance operations omap: enable caches at system start-up arm: do not force d-cache enable on all boards ORIGEN: Add MMC SPL support ARMV7: Add support for Samsung ORIGEN board i2c:gpio:s5p: Enable I2C GPIO on the GONI target i2c:gpio:s5p: I2C GPIO Software implementation (via soft_i2c) Tegra2: Use clock and pinmux functions to simplify code Tegra2: Add additional pin multiplexing features Tegra2: Add more clock support Tegra2: Add microsecond timer function ARM: remove broken "at91rm9200dk" board ARM: remove broken "m501sk" board ARM: remove broken "kb9202" board ARM: remove broken "csb637" board ARM: remove broken "cmc_pu2" board ARM: remove broken "at91cap9adk" board ARM: remove broken "voiceblue" board ARM: remove broken "smdk2400" board ARM: remove broken "sbc2410x" board ARM: remove broken "netstar" board ARM: remove broken "mx1fs2" board ARM: remove broken "lpd7a40x" boards ARM: remove broken "edb93xx" boards ARM: remove broken "B2" board ARM: remove broken "armadillo" board ARM: remove broken "assabet" board ARM: versatile: drop warnings IMX: scb9328: drop warnings MX31: imx31_litekit: make use of GPIO framework MX31: mx31ads: make use of GPIO framework MX5: mx51evk: make use of GPIO framework MX35: mx35pdk: make use of GPIO framework MX5: mx53loco: make use of GPIO framework MX5: mx53evk: make use of GPIO framework MX5: vision2: make use of GPIO framework MX5: mx53smd: make use of GPIO framework MX5: mx53ard: make use of GPIO framework MX25: zmx25: make use of GPIO framework MX5: efikamx: make use of GPIO framework MX31: QONG: make use of GPIO framework MX35: make use of GPIO framework for MX35 processor MX5: make use of GPIO framework for MX5 processor MX31: make use of GPIO framework for MX31 processor MX25: make use of GPIO framework for MX25 processor IMX: uniform GPIO interface using GPIO framework MX: MX35 / MX5: uniform clock command with powerpc MX35: MX35PDK: support additional RAM on CSD1 mx53: ddr3: Update DD3 initialization ARM: MX51: PLL errata workaround ARM: versatilepb : drop warnings due to double definitions omap4: increase SRAM budget to fix build error omap4: fix build warning due to signed unsigned comparison mkimage: Fix 'Unknown OMAP image type -
