[U-Boot] PCIe related i.MX6QP patches
by David Müller (ELSOFT AG) 07 Jul '15

07 Jul '15

Hello Do you have some PCIe related i.MX6QP patches which you could make public? I have a i.MX6QP based custom board which seems to work quite well expect for PCIe. The first access done by U-Boot to the PCIe host controller registers causes a hang. I assume a not correctly enabled clock to be the culprit. TIA Dave

[U-Boot] rpi USB address question
by Simon Glass 07 Jul '15

07 Jul '15

Hi Stephen, I see in the kernel device tree that the rpi uses address 0x7e980000 for the DWC2 USB controller. But in U-Boot CONFIG_USB_DWC2_REG_ADDR is set to 0x20980000. Is there some sort of translation going on here? Regards, Simon

[U-Boot] [PATCH] usb: CONFIG_USB_FASTBOOT prefix replacement for consistency
by PaulK 07 Jul '15

07 Jul '15

From: Paul Kocialkowski <contact(a)paulk.fr> FASTBOOT is defined both by CONFIG_USB_FUNCTION_FASTBOOT AND CONFIG_CMD_FASTBOOT, so it doesn't make much sense to have a CONFIG_USB_FASTBOOT prefix for fastboot-specific options, especially given that other config options for fastboot use the CONFIG_FASTBOOT prefix. This replaces the CONFIG_USB_FASTBOOT prefix with CONFIG_FASTBOOT, for consistency.

[U-Boot] [PATCH 0/6] Add support for hi6220 SoC and HiKey 96boards CE board.
by Peter Griffin 06 Jul '15

06 Jul '15

This series adds support for the first 96boards consumer edition HiKey board. More information can be found about this board at the following link https://www.96boards.org/products/hikey/. This initial port adds support for: - 1) Serial 2) eMMC and sd card 3) USB 4) GPIO It has been tested with Arm Trusted Firmware running u-boot as the BL33 executable. Some (slightly old) instructions on exactly how to compile everything (l-loader, with Arm Trusted Firmware, which then loads u-boot are available here: - http://people.linaro.org/~peter.griffin/hikey/hikey-u-boot-release_r1/u-boo…. One thing I'm fairly sure is wrong but can't see how to fix is the header definitions are currently in arch/arm/include/asm/arch-armv8/*.h and I suspect they should be in a directory something like arch/arm/include/asm/arch-hi6220. However so far what makes this magic happen and how to fix it has aluded me. Notes: eMMC has been tested with basic reading of eMMC partition into DDR. I have not tested writing / erasing. I suspect due to lack of clock control it won't be running in the most performant high speed mode. SD card slot has been tested for reading and booting kernels into DDR. It is also currently used for saving the u-boot enviroment. USB has been tested with ASIX networking adapter to tftpboot kernels into DDR. USB mass storage device enumeration does not currently work for an unknown reason (leads to a hang). GPIO has been tested using gpio toggle command GPIO4_1-3 to flash LEDs. A basic SoC datasheet can be found here: - https://github.com/96boards/documentation/blob/master/hikey/ Hi6220V100_Multi-Mode_Application_Processor_Function_Description.pdf Board schematic can be found here: - https://github.com/96boards/documentation/blob/master/hikey/ 96Boards-Hikey-Rev-A1.pdf kind regards, Peter.

Hi Tom, Here is a rebased / fixed version of my previous pull-req for two bug-fixes, and one new board. Since the first one was no good I've done a forced push with the new one to u-boot-sunxi/master .
