[U-Boot] [PATCH] tpm: Remove the LPC TPM driver
by Marek Vasut 04 Oct '12

04 Oct '12

The driver is not used anywhere. It is a dead code and it seems to be falling apart slowly due to bitrot. Remove this driver.

[U-Boot] [PATCH V4] i.MX6: mx6qsabrelite: Add splash screen support
by Eric Nelson 03 Oct '12

03 Oct '12

Adds support for two LVDS panels and one RGB panel to the SABRE-Lite board: Hannstar-XGA - 1024 x 768 LVDS (Freescale part number MCIMX-LVDS1) wsvga-lvds - 1024 x 600 LVDS (Boundary p/n Nit6X_1024x600) wvga-rgb - 800 x 480 RGB (Boundary p/n Nit6X_800x480) Auto-detects panel by probing the I2C touch controller of each. Setting 'panel' environment variable to one of the names above will override auto-detection.

[U-Boot] [PATCH 0/2] Add support for MINI2440 (s3c2440)
by Gabriel Huau 03 Oct '12

03 Oct '12

>From the last time, I removed the patch about the PLL initialization because it's board specific. I added a new patch for s3c440 gpio driver. Now in the board file we have no more magic bloat. >> +/* >> + * When booting from NAND, it is impossible to access the lowest addresses >> + * due to the SteppingStone being in the way. Luckily the NOR doesn't really >> + * care about the highest 16 bits of address, so we set the controlers >> + * registers to go and poke over there, instead. >> + */ >> +#define PHYS_FLASH_1 0x0 >> +#define CONFIG_SYS_FLASH_BASE 0x0 > >Urghh... this sounds very much like a serious design issue? About this point, I ported it from the old version uboot as well. It may need some investigation, but I remember it was a big problem with this board. In the case of a NAND boot, we don't have access to NOR because the SteppingStone (SRAM) is mapped at the same range.

[U-Boot] [PATCH for-rc] lsxl: also turn off fan in power down mode
by Michael Walle 03 Oct '12

03 Oct '12

If while booting the power switch is in OFF position, turn off the fan, too. Signed-off-by: Michael Walle <michael(a)walle.cc> Cc: Prafulla Wadaskar <prafulla(a)marvell.com> --- Hi Tom, Hi Prafulla, while testing, i noticed i've forgot to turn off the fan in power down mode which was introduced in commit a9f1a4893364dd. Tom, can you pick this bugfix patch so it can make it into the 2012.10 release?

[U-Boot] [PATCH 0/6] bootstage: Add a number of new features
by Simon Glass 03 Oct '12

03 Oct '12

It is useful to be able to communicate the bootstage information to another program, such as the kernel, either by putting it in memory or the device tree. This makes the information accessible after boot so that it can easily be logged somewhere or perhaps reported back for diagnostics purposes. This series includes a few patches to implement this. Sometimes a peripheral is touched multiple times during boot, or a single task is called repeatedly. Examples are reading from a device, which might happen in several parts, or setting up an LCD display, which may involve multiple steps to comply with backlight power sequences. This series adds a new bootstage time accumulation feature to add up all the time spent in a particular task. This series also adds a new command 'bootstage' to provide access to the above features.

[U-Boot] [PATCH] mpc52xx/motionpro: fix monitor size and update default environment
by Wolfgang Grandegger 03 Oct '12

03 Oct '12

Since a while, the size of the u-boot.bin image is larger than 256kB. This requires moving the environment sectors by one. As we are at it, we also update a few other custom settings.
