2014-12-04omap_hsmmc: Board-specific TWL4030 MMC power initializationsPaul Kocialkowski
Boards using the TWL4030 regulator may not all use the LDOs the same way (e.g. MMC2 power can be controlled by another LDO than VMMC2). This delegates TWL4030 MMC power initializations to board-specific functions, that may still call twl4030_power_mmc_init for the default behavior.

2014-12-04twl4030: device-index-specific MMC power initializations, common ramp-up delayPaul Kocialkowski

2014-12-01mxs_ocotp: prevent error path from returning successHector Palacios
The code may goto 'fail' upon error with 'ret' variable set to an error code, but this variable was being overwritten by a final preparation function to restore the HCLK, so success was (in general) returned even after an error was hit previously. With this change, the function may now return success even if the final preparation function fails, but it's probably enough to print a message because (if successful) the real programming of the fuses has already completed.

2014-11-26mtd: denali: set some registers after nand_scan_ident()Masahiro Yamada
Some but not all of implementations of the Denali NAND controller have hardware circuits to detect the device parameters such as page_size, erase_size, etc. Even on those SoCs with such hardware supported, the hardware is known to detect wrong parameters for some nasty (almost buggy) NAND devices. The device parameters detected during nand_scan_ident() are more trustworthy. This commit sets some hardware registers to mtd->pagesize, mtd->oobsize, etc. in the code between nand_scan_ident() and nand_scan_tail().

Some variants of the Denali NAND controller need some registers set up based on the device information that has been detected during nand_scan_ident(). CONFIG_SYS_NAND_SELF_INIT has to be defined to insert code between nand_scan_ident() and nand_scan_tail(). It is also helpful to reduce the difference between this driver and its Linux counterpart because this driver was ported from Linux. Moreover, doc/README.nand recommends to use CONFIG_SYS_NAND_SELF_INIT.

2014-11-25bios_emulator: Always print errors when opcode decode failsSimon Glass

2014-11-25pci: Add general support for execution of video ROMsSimon Glass
Some platforms don't have native code for dealing with their video hardware. In some cases they use a binary blob to set it up and perform required actions like setting the video mode. This approach is a hangover from the old PC days where a ROM was provided and executed during startup. Even now, these ROMs are supplied as a way to set up video. It avoids the code for every video chip needing to be provided in the boot loader. But it makes the video much less flexible - e.g. it is not possible to do anything else while the video init is happening (including waiting hundreds of milliseconds for display panels to start up). In any case, to deal with this sad state of affairs, provide an API for execution of x86 video ROMs, either natively or through emulation. Signed-off-by: Simon Glass <sjg@chromium.org>

2014-11-25sunxi: video: Add cfb console driver for sunxiLuc Verhaegen
This adds a fixed mode hdmi driver for the sunxi platform. The fixed mode is a relatively safe 1024x768, more complete EDID handling is currently not provided. Only HDMI is supported today. This code is enabled when HPD detects an attached monitor. Current config is such that 8MB is shaved off at the top of the RAM. This avoids several memory handling issues, most significant is the fact that on linux on ARM you are not allowed to remap known RAM as IO. A clued in display driver will be able to recycle this reserved RAM in future though. cfbconsole was chosen as it provides the most important functionality: a working u-boot console, allowing for the debugging of certain issues without the need for a UART.
