[U-Boot] [PATCH] moveconfig: Add a new --git-ref option
by Joe Hershberger 13 Jun '16

13 Jun '16

This option allows the 'make *_defconfig' step to run against a former repo state, while the savedefconfig step runs against the current repo state. This is convenient for the case where something in the Kconfig has changed such that the defconfig is no longer complete with the new Kconfigs. This feature allows the .config to be built assuming those old Kconfigs, but then savedefconfig based on the new state of the Kconfigs.

[U-Boot] [PATCH v3 00/11] arm: rpi: Enable USB and Ethernet driver model Raspberry Pi

Raspberry Pi uses a DWC2 USB controller and a SMSC USB Ethernet adaptor. Driver model support for these was recently merged. 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) - 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 Changes in v3: - Drop applied patches from series - Drop patch to introduce usbethaddr for driver model - Rename binding file to pl01x.txt Changes in v2: - Add support for Raspberry Pi 2 Simon Glass (11): dm: serial: Update binding for PL01x serial UART arm: rpi: Define CONFIG_TFTP_TSIZE to show tftp size info arm: rpi: Bring in kernel device tree files arm: rpi: Device tree modifications for U-Boot arm: rpi: Add device tree files for Raspberry Pi 2 arm: rpi: Enable device tree control for Rasberry Pi arm: rpi: Enable device tree control for Rasberry Pi 2 arm: rpi: Drop the UART console platform data arm: rpi: Drop the GPIO platform data arm: rpi: Move to driver model for USB arm: rpi: Use driver model for Ethernet arch/arm/dts/Makefile | 3 + arch/arm/dts/bcm2835-rpi-b.dts | 24 ++++ arch/arm/dts/bcm2835.dtsi | 35 +++++ arch/arm/dts/bcm2836-rpi-2-b.dts | 30 +++++ arch/arm/dts/bcm2836.dtsi | 42 ++++++ arch/arm/dts/bcm283x-common.dtsi | 157 ++++++++++++++++++++++ arch/arm/dts/bcm283x-rpi.dtsi | 49 +++++++ arch/arm/dts/stv0991.dts | 2 +- arch/arm/mach-bcm283x/include/mach/gpio.h | 5 - board/raspberrypi/rpi/rpi.c | 24 ---- configs/rpi_2_defconfig | 6 + configs/rpi_defconfig | 6 + doc/device-tree-bindings/arm/bcm/brcm,bcm2835.txt | 8 ++ doc/device-tree-bindings/arm/bcm/brcm,bcm2836.txt | 10 ++ doc/device-tree-bindings/serial/pl01x.txt | 55 +++++++- drivers/gpio/bcm2835_gpio.c | 20 +++ drivers/serial/serial_pl01x.c | 6 +- include/configs/rpi-common.h | 6 +- include/dt-bindings/pinctrl/bcm2835.h | 27 ++++ 19 files changed, 474 insertions(+), 41 deletions(-) create mode 100644 arch/arm/dts/bcm2835-rpi-b.dts create mode 100644 arch/arm/dts/bcm2835.dtsi create mode 100644 arch/arm/dts/bcm2836-rpi-2-b.dts create mode 100644 arch/arm/dts/bcm2836.dtsi create mode 100644 arch/arm/dts/bcm283x-common.dtsi create mode 100644 arch/arm/dts/bcm283x-rpi.dtsi create mode 100644 doc/device-tree-bindings/arm/bcm/brcm,bcm2835.txt create mode 100644 doc/device-tree-bindings/arm/bcm/brcm,bcm2836.txt create mode 100644 include/dt-bindings/pinctrl/bcm2835.h -- 2.5.0.rc2.392.g76e840b

[U-Boot] [PATCH] net: Add mv88e60xx support to the mv88e61xx driver
by Joshua Scott 26 Apr '16

26 Apr '16

The Marvell Link Street mv88e60xx is a series of FastEthernet switch chips, some of which also support Gigabit ports. It is similar to the mv88e61xx series which support Gigabit on all ports. There is already a driver for the mv88e61xx in U-Boot, and this patch updates it to also work with the mv88e60xx. The main change that was required was the size of the port bitmaps. Previously, 8-bit port bitmaps were in use, as the driver had only been used with six-port mv88e61xx devices. This has been changed so that 16-bit port bitmaps are now used, which covers the largest port-counts available for the mv88e60xx / mv88e61xx.

[U-Boot] [PATCH V4 1/3] arm: discard relocation entries for secure text
by Peng Fan 31 Mar '16

31 Mar '16

The code such as PSCI in section named secure is bundled with u-boot image, and when bootm, the code will be copied to their runtime address same to compliation/linking address - CONFIG_ARMV7_SECURE_BASE. When compile the PSCI code and link it into the u-boot image, there will be relocation entries in .rel.dyn section for PSCI. Actually, we do not needs these relocation entries. If still keep the relocation entries in .rel.dyn section, r0 at line 103 and 106 in arch/arm/lib/relocate.S may be an invalid address which may not support read/write for one SoC. 102 /* relative fix: increase location by offset */ 103 add r0, r0, r4 104 ldr r1, [r0] 105 add r1, r1, r4 106 str r1, [r0] So discard them to avoid touching the relocation entry in arch/arm/lib/relocate.S.

[U-Boot] [PATCH] tools/kwboot.c: Support UART fallback mode
by Kevin Smith 29 Mar '16

29 Mar '16

On some processors such as Armada 38x, if the hardware- configured boot mode fails, the CPU falls back to booting over UART. When this happens the chip prints a failure message, waits for the magic sequence and, when it is received, prints a "(boot)" message, then sends a NAK to start the transfer. This breaks the current kwboot behavior because the xmodem transfer only tries to read one character after the magic sequence, looking for the NAK. Instead it gets the "(boot)" text, and retries the magic sequence. The CPU thinks the repeated sequence is part of the packet, stops NAKing, and one side or another eventually times out. This patch adds support for a fallback mode which continues to scan for a NAK in the characters received after the sequence, printing out any non-NAK characters. This allows kwboot to skip the "(boot)" message, find the NAK, and start the transfer successfully.
