[U-Boot] [PATCH] mxs: fixed battery boot on imx233-olinuxino-micro
by Peter Schumann 20 Aug '14

20 Aug '14

This patch makes it possible to boot from battery on olinuxino Boards from Olimex. We should not set DOUBLE_FETS in HW_POWER_MINPWR, it makes my system reset with in seconds while running on battery power. Also mxs_power_enable_4p2() should not be called if running from battery. It switches VDDD and VDDA to LinReg mode and than turns off the VDDIO DCDC supply. At this point the system resets. If we run on battery this is no good idea because the LinRegs are chained behind VDDIO and battery voltage seems not enough to power the system from LinRegs. Also is the power system already running on DCDC after BootROM hands over to u-boot, so no sense in switching back to LinRegs. --- arch/arm/cpu/arm926ejs/mxs/spl_power_init.c | 6 ------ 1 file changed, 6 deletions(-) diff --git a/arch/arm/cpu/arm926ejs/mxs/spl_power_init.c b/arch/arm/cpu/arm926ejs/mxs/spl_power_init.c index d25019a..0cbb6c4 100644 --- a/arch/arm/cpu/arm926ejs/mxs/spl_power_init.c +++ b/arch/arm/cpu/arm926ejs/mxs/spl_power_init.c @@ -237,9 +237,6 @@ static void mxs_src_power_init(void) POWER_LOOPCTRL_RCSCALE_THRESH | POWER_LOOPCTRL_EN_RCSCALE_8X); - clrsetbits_le32(&power_regs->hw_power_minpwr, - POWER_MINPWR_HALFFETS, POWER_MINPWR_DOUBLE_FETS); - /* 5V to battery handoff ...

[U-Boot] [PATCH 1/6] usb: ehci: mx6: Add support for i.MX6SL
by Otavio Salvador 18 Aug '14

18 Aug '14

The i.MX6SL has a different base address for the controller. This patch adapts the driver to support the different base address for this case.

[U-Boot] [PATCH] vf610twr: Tune DDR initialization settings
by Anthony Felice 15 Aug '14

15 Aug '14

Removed settings in unsupported register fields. They didn’t do anything, and in most cases, were not documented in the reference manual. Changed register settings to comply with JEDEC required values. Changed timing parameters because they included full clock periods that were doing nothing.

[U-Boot] Build broken for bf538f-ezkit board - not enough ram
by Vasili Galka 15 Aug '14

15 Aug '14

Hi, Some of the recent commits on u-boot/master have broken the build of bf538f-ezkit board. The build was fine for v2014.07-rc3. However, now there is the following error: bfin-elf-ld.bfd: u-boot section `.bss' will not fit in region `ram' bfin-elf-ld.bfd: region `ram' overflowed by 40 bytes I did not pin-point exactly what has increased the image size, and if the growth is in the .text or .bss section. Maybe some of the features shall be dropped from the board config to decrease the size. Also, may be related: http://lists.denx.de/pipermail/u-boot/2014-April/177928.html Best, Vasili

[U-Boot] [PATCH] OpenRD: relocate environment to 640kB
by Sascha Silbe 14 Aug '14

14 Aug '14

U-Boot has become slightly larger than where the environment sector was previously located. Saving the environment would brick the device. Relocate the environment to where it is with the stock (i.e. Marvell USP) U-Boot version. That should give plenty of room for U-Boot to grow, including local customisations. This obviously breaks compatibility with previous mainline versions of U-Boot. Users will need to back up the environment before an update and restore it afterwards, or manually copy it to the new address before the update.

[U-Boot] CPU Wachtog for P2041
by Rainer Boschung 14 Aug '14

14 Aug '14

I am using the core watchdog of the P2041 on the kmp204x board. For the watchdog initialization I use the mpc85xx framework and the powerpc register definitions. However, I had to modify both for the following reasons (Patches 1 to 4): -the e500mc register implementation differs from other ppc -the watchdog init function was missing Additional function was added to the kmp204x board to use the core WD reset in conjunction with the board specific reset controller (Patches 5 to 9): -trigger a core reset flow upon core WD reset request -check for core WD reset occurance and set the reset reason register accordingly. Regards Rainer

[U-Boot] [PATCH] video: ipu_disp: squash clang warning
by Jeroen Hofstee 11 Aug '14

11 Aug '14

Since &rgb2ycbcr_coeff and friends are declared const, but assigned to a void pointer, clang will warn that the const is implicity casted away. Add const to indicate the pointer points to const data to get rid of these warnings.

[U-Boot] [PATCH] video: ipu_disp: wait for DP SF end irq when disabling sync BG flows
by Liu Ying 11 Aug '14

11 Aug '14

Instead of waiting for DC triple buffer to be cleared, this patch changes to wait for a relevant DP sync flow end interrupt to come when disabling sync BG flows. In this way, we align the implement to the freescale internal IPUv3 driver. After applying this patch, an uboot hang up issue at the arch_preboot_os() stage, where we disable a relevant ipu display channel, is not observed any more on some MX6DL platforms.
