[U-Boot] [PATCH 00/20] arm: rpi: Enable USB and Ethernet driver model Raspberry Pi
by Simon Glass 19 Oct '15

19 Oct '15

Raspberry Pi uses a DWC2 USB controller and a SMSC USB Ethernet adaptor. Neither of these currently support driver model. This series does the following: - Move Raspberry Pi to use device tree control (u-boot-dtb.bin instead of u-boot.bin) - Remove GPIO platform data (now uses device tree) - Remove serial platform data (now uses device tree) - Add 'ranges' support to simple-bus - Convert the DWC2 USB driver to support driver model - Convert the SMSC95XX USB Ethernet driver to support driver model - Enable CONFIG_DM_ETH and CONFIG_DM_USB on Raspberry Pi With Ethernet active the device list looks something like this: U-Boot> dm tree Class Probed Name ---------------------------------------- root [ + ] root_driver simple_bus [ + ] |-- soc gpio [ ] | |-- gpio@7e200000 serial [ + ] | |-- uart@7e201000 usb [ + ] | `-- usb@7e980000 usb_hub [ + ] | `-- usb_hub usb_hub [ + ] | `-- usb_hub eth [ + ] | `-- smsc95xx_eth simple_bus [ ] `-- clocks Raspberry Pi 2 is not converted as I do not have one to test at present.

[U-Boot] [PATCH] ARM: dockstar: move start of environment area
by Eric Cooper 19 Oct '15

19 Oct '15

The default dockstar configuration for U-Boot currently causes it to overrun the environment area, so that a "saveenv" command bricks the device. This patch moves the environment to a higher address to avoid that.

This series collects the previous RFT patches I sent out. https://patchwork.ozlabs.org/patch/508167/ https://patchwork.ozlabs.org/patch/508168/ It turns out that I originally sent a version of these in April: https://patchwork.ozlabs.org/patch/461687/ https://patchwork.ozlabs.org/patch/461690/ so this series mirrors that one and includes the Zynq patches from that series. I have tested this on a few ARM platforms: Zynq Zybo, Beaglebone Black, pcduino3 (sunxi), Jetson-TK1 (tegra).

by Sjoerd Simons 19 Oct '15

Further testing with u-boot on Rockchip revealed that loading the initrd above 512M seems to be problematic (just like with the dtb) and ofcourse that not being able to save the environment is annoying :) Resolve these things.

[U-Boot] [PATCH 1/3] x86: ivybridge: Fix saving mrc cache and enable it
by Bin Meng 19 Oct '15

19 Oct '15

Currently sdram_initialise() saves pei_data->mrc_output directly to gd->arch.mrc_output. This is incorrect as pei_data->mrc_output points to an address on the stack whose content is no longer valid when we call mrccache_reserve(). To fix this, save it on the heap instead.
