[U-Boot] beagle-xm boot logo / DSS in u-boot
by Peter Meerwald 27 Jan '12

Hello, u-boot has some code for beagleboard to initialize DVI (?), i.e. beagle_display_init(); omap3_dss_enable(); as well as CONFIG_VIDEO_OMAP3 what is the expected output? this doesn't seem to do anything I understand that there is no code to actually output an image, but I would expect that there is atleast a black screen any idea what might be missing? thanks, regards, p. -- Peter Meerwald +43-664-2444418 (mobile)

[U-Boot] [PATCH V3 0/6] mxc_spi refactoring (for mx6q and mx6qsabrelite)
by Eric Nelson 27 Jan '12

27 Jan '12

This patch set refactors mxc_spi as described in http://lists.denx.de/pipermail/u-boot/2010-March/068791.html and requested in http://lists.denx.de/pipermail/u-boot/2012-January/116023.html in order to add support for the MX6Q in general and the mx6qsabrelite specifically. Patch 1 simply moves the conditional parts of mxc_spi.c into the respective CPU-specific imx-regs.h files. Patch 2 adds general support for SPI to the i.MX6. Patch 3 adds support to the mx6qsabrelite board Patch 4 modifies the 'sf' command to allow a default chip-select to be specified by board headers as is done on efika et al. This allows a bare 'sf' probe command: U-Boot> sf probe instead of the more cumbersome usage when a GPIO is tacked onto the chip-select. Otherwise, this command-line would be needed to specify GP3:19 on SabreLite: U-Boot> sf probe 0x5300 Patch 5 adds default chip-select values for mx6qsabrelite platform. Patch 6 adds reference macros for use in storing the environment in serial flash to match the use on Freescale's U-Boot release This patch set has been compiled against the following configurations, but only tested on mx6qsabrelite: mx6qsabrelite mx51evk mx31pdk mx35pdk

[U-Boot] changes in uEnv.txt does not work
by manish kanchan 26 Jan '12

26 Jan '12

Hi, I am Manish and i have recently started working on beagleboard xm. I am facing certain issues. Need guidance to solve it. Background: I am using beagleboard xm, uboot version 9 of 2011 Intention: Current version of uboot has the environment variable loaduimage set for ext3 partition.Now i want the uboot to pick the uimage from fat partition. I can do it by modifying the uboot code and use the rebuilt uboot but i want to remove dependency on building uboot for future version. So i was trying to play around with uEnv.txt Exercise: Initially i tried to update loaduimage to fatload mmc ${mmcdev} ${loadaddr} uImage and tried booting but was unsuccessful. I tried to uncover the problem by echo statements to track the code flow. I observed that the 1.Same command works when i change the omap3_beagle.h and rebuild the uboot but it does not work if i change it using uEnv.txt. 2.Also that the error is returned from mmcboot->bootm command saying the image is in wrong format. But i am using the same image as in case 1. Can some on guide me how do i achive this. I want to use uEnv.txt for better maintanibilty Manish Kanchan

[U-Boot] [RFC Patch] e1000: Fix PCI memory addressing and fix for receive data polling
by Ralf Rösch 26 Jan '12

26 Jan '12

Sorry, you will find now my fixes in attachment Hi all, I had some problem when using your e1000-code on a MIPS target. Attached you will find two fixes which I would like to propose for discussion. - Fix 1: this has the same reason as in commit f81ecb5d3300bf92d17302d3712f30585c182da9 - Fix 2: has to do with "C Language Operator Precedence". I would say the expression taken by the ! operator has precedence before the & operator. So any bit in rd->status other than E1000_RXD_STAT_DD stops correct detection of data reception. (What i do not know is, if it is possible that any other bit than E1000_RXD_STAT_DD can get active) Please leave me in CC, because i'm not subscribed to this list. Thanks a lot for providing u-boot.

[U-Boot] [PATCH 1/2] ARM: tegra: Define Tegra20 CAR binding
by Stephen Warren 25 Jan '12

25 Jan '12

Document a binding for the Tegra20 CAR (Clock And Reset) Controller, add it to tegra20.dtsi, and configure it for the board in tegra- seaboard.dts. Signed-off-by: Stephen Warren <swarren(a)nvidia.com> --- v2: * Remove clock-names, clock-output-names properties; Tegra will solely use integer IDs for clocks in DT. * Fixed typo in compatible flag * Resolve FIXME re: multiple clocks with the same "reset ID"; give each unique clock an ID, and ignore the reset bits, since this is purely a clock binding. Code (e.g. U-Boot) that wants to use this to determine CAR reset bit numbers would need a table to convert from the clock IDs in this binding to the related reset bit number, if any. In general, I think that's true, and the U-Boot code that handles "peripheral IDs" should be reworked to handle "clocks", the peripheral clocks being a subset of all clocks. * Define clock IDs for all the non-peripheral clocks too; inputs, PLLs, etc. * Separate tegra-seaboard.dts usage example into a separate patch. This patch semantically relies on Grant Likely's common clock binding patch series. Once that's finalized, this patch could be checked into the kernel provided there are no relevant changes to Grant's patches. I believe that Simon Glass wants to start using this within U-Boot ASAP though. --- .../bindings/clock/nvidia,tegra20-car.txt | 164 ++++++++++++++++++++ arch/arm/boot/dts/tegra20.dtsi | 6 + 2 files changed, 170 insertions(+), 0 deletions(-) create mode 100644 Documentation/devicetree/bindings/clock/nvidia,tegra20-car.txt diff --git a/Documentation/devicetree/bindings/clock/nvidia,tegra20-car.txt b/Documentation/devicetree/bindings/clock/nvidia,tegra20-car.txt new file mode 100644 index 0000000..acce2d9 --- /dev/null +++ b/Documentation/devicetree/bindings/clock/nvidia,tegra20-car.txt @@ -0,0 +1,164 @@ +NVIDIA Tegra20 Clock And Reset Controller + +This binding uses the common clock binding: +Documentation/devicetree/bindings/clock/clock-bindings.txt + +The CAR (Clock And Reset) Controller on Tegra is the HW module responsible +for muxing and gating Tegra's clocks, and setting their rates. + +Required properties : +- compatible : Should be "nvidia,<chip>-car" +- reg : Should contain CAR registers location and length +- clocks : Should contain phandle and clock specifiers for two clocks: + the 32 KHz "32k_in", and the board-specific oscillator "osc". +- #clock-cells : Should be 1. + In clock consumers, this cell represents the clock ID exposed by the CAR. + + The first 96 clocks are numbered to match the bits in the CAR's CLK_OUT_ENB + registers.
