[U-Boot] [PATCH] spl: fix debug print in spl_common_init()
by Simon Goldschmidt 20 Aug '18

20 Aug '18

spl_common_init() debug-prints "spl_early_init()\n" but it is called both from spl_early_init() and spl_init(). Fix this by moving the debug() statement to the calling functions which now print their name.

[U-Boot] [PATCH V2] drivers: regulator: fixed: add u-boot, off-on-delay-us
by Peng Fan 20 Aug '18

20 Aug '18

Add u-boot,off-on-delay-us for fixed regulator. Depends on board design, the gpio regulator sometimes connects with a big capacitance. When need to off, then on the regulator, if there is no enough delay, the voltage does not drop to 0, so introduce this property to handle such case.

[U-Boot] U-Boot RPI bmp display isn't visible

Hello community, thank you for providing such a good software. I hope this is the right way to get help. I successfully run my RPI3b with u-boot and buildroot. I have attached the official 7“ touch display for the rpi. Which also works fine in linux. When I want to display a bmp on the display in u-boot nothing is displayed and no error is shown. The following is the output on the serial console and also on the display: ``` U-Boot 2018.07 (Aug 20 2018 - 17:00:45 +0200) DRAM: 768 MiB RPI 3 Model B (0xa02082) MMC: mmc@7e202000: 0, sdhci@7e300000: 1 Loading Environment from FAT...

[U-Boot] [PATCH v3 00/34] Add support for 1wire protocol and 1wire eeproms
by Eugen Hristev 20 Aug '18

20 Aug '18

This is a patch series originally written by Maxime Ripard, https://lists.denx.de/pipermail/u-boot/2016-November/272138.html titled: [U-Boot] [PATCH RESEND 0/9] sunxi: chip: Enable the DIP auto-detection and reworked to include support for the EEPROMs on the PDAs connected to the sama xplained boards. This is the version 3 of the rework, version 1 was titled: [PATCH 00/20] Add support for 1wire protocol and 1wire eeproms and version 2 was titled: [PATCH v2 00/30] Add support for 1wire protocol and 1wire eeproms It addresses feedback received in the first version and fixes a few bugs found in the second version. The patch series adds first a driver for onewire uclass, and onewire over gpio bitbanging driver. Then it adds a uclass for onewire EEPROMS, and specific driver for Maxim EEPROMs. I have added some sandbox support, configuration and device tree for it and for boards sama5d2_xplained, sama5d3_xplained, sama5d4_xplained, sama5d2_ptc_ek and sama5d27_som1_ek. Also added common code for PDA detection, as the memory on the PDAs is connected to the SoC on the onewire bus. Thanks to everyone for the review and feedback.

This is done in patch: [PATCH v3 34/34] ARM: dts: at91: sama5d4_xplained: add onewire connector for LCD eeprom Changes in v3: - add suport for sama5d4 xplained. - modified the reset ops for the w1-gpio driver to also check for bus release by the memory after the presence pulse. This is done to avoid the case when the bus is being kept indefinitely at low, thus confusing the detection algorithm. - fixed issue in w1-uclass when the id for the child node was improperly saved - fixed issue when the gpio driver was returning only FFs but the read buf function error code was not checked. Changes in v2: - added support for two more boards: the PTC ek and the SOM1 ek. - modified the enumerate mechanism, to search through devicetree nodes, the memories are now in device tree, as suggested by Simon Glass. When a serial number is read from the bus, the driver will match it with a corresponding node in device tree. - modified the probe mechanism for the bus, when trying to get the bus use a different get function that will also probe the driver, regardless of present aliases in DT. - added bindings for ds24xxx driver and eep_sandbox, because they are referenced from devicetree now.

[U-Boot] [PATCH] board: sunxi: Remove unused local variables
by Jagan Teki 20 Aug '18

variables buf from board_mmc_init, and ret from misc_init_r were unused on the functions, so remove it.
