[U-Boot] [PATCH v1 1/2] cmd_sf: Add command "sf info" to show current device info
by Haikun Wang 07 Aug '15

07 Aug '15

Add command "sf info" to show the information of the current SPI flash device. Signed-off-by: Haikun Wang <haikun.wang(a)freescale.com> --- In current sf driver, we show the debug information during the flash probe period. In case of without DM SPI, we need to run command "sf probe" to get the debug information of the current SPI flash device. "sf probe" will re-identify the device every time and it reduce the efficiency. We can get the debug information without any re-identify process using "sf info". In case of using DM SPI, if we disable CONFIG_DM_DEVICE_REMOVE "sf probe" will only call the flash driver's probe function the first time you run it and no information will show after the first. It is recommended that only call the flash driver's probe function once during u-boot period. You can get the debug information using "sf info" in this case.

[U-Boot] [PATCH] patman: Don't run patman when it is imported as a module
by Simon Glass 07 Aug '15

Commit 488d19c (patman: add distutils based installer) has the side effect of making patman run twice with each invocation. Fix this by checking for 'main program' invocation in patman.py.

[U-Boot] [PATCH 00/15] x86: minnowmax: Add interrupt support
by Simon Glass 07 Aug '15

07 Aug '15

This series brings in interrupt support for Minnowmax, so that PCI interrupts are correctly set up for Linux. It also includes a few small improvements to the PCI driver model implementation and tidies up some nits in the code. The existing pirq routing code does not seem to support the Atom used in the Minnowmax. I'd like to figure that out before applying the RFC patch.

[U-Boot] [PATCH v3 00/25] dm: Introduce Rockchip RK3288 support
by Simon Glass 07 Aug '15

07 Aug '15

The Rockchip RK3288 is based on a quad-core Cortex-A17 CPU and has a good set of peripherals. Various full-featured U-Boot ports are available and this is an attempt to bring those features into mainline. With this series the Firefly RK3288 can boot to a prompt from an SD card. Since much of the code is generic, this also supports the Radxa Rock Pro. Since there is no device tree available for that yet, it uses the same config and device tree as the Firefly. This works because not all peripherals are supported, so the differences don't matter. Support for booting from USB OTG is also provided, using the on-chip boot ROM and the rkflashtool utility. This can boot as far as SPL, but there is no support for reading U-Boot proper from USB as yet. This requires implementing a suitable protocol (perhaps DFU or Rockchip's proprietary one) in SPL. Support is also provided for the Haier Chromebook, which is based on the same SoC. In this case it boots from SPI rather than an SD card. The basic approach here is to use driver model for everything, so this series adds several new uclasses. Some of these have been discussed for a while. The list is: - Clocks - setting and getting PLL and peripheral clocks - Pinctrl - adjusting pin multiplexing settings - Reset - reseting the board or SoC - RAM - setting up RAM controllers and detecting the available RAM - MMC - MMC controllers (using the existing block device framework) - LEDs - turning LEDs on and off, with only a GPIO driver so far Trivial support is also added for regmap and syscon controllers, modelled on how the kernel does this. This series avoids hard-coding RK3288-specific code into the build. There is a CONFIG_ROCKCHIP_RK3288 but it only *adds* support for RK3288. In principle another CONFIG could add support for a different Rockchip SoC with only the device tree selecting which one U-Boot works on. Support is provided in mkimage to build these image types: - rkimage - suitable for packaging up SPL to be sent to the boot ROM over USB OTG - rksd - suitable for writing to an SD card Much of the source and ideas for this series came from downstream Rockchip U-Boot trees. SDRAM init came from Coreboot. In most cases it has been pretty heavily cleaned up / rewritten to meet U-Boot style and remove hard-coding of things. Drivers are provided for: - Clocks - Pinctrl - SoC reset - DDR3 SDRAM - I2C - SPI - GPIOs - LEDs using GPIOS - MMC - Firefly main PMIC (ACT8846) and included regulators These are lightly tested and doubtless some problems exist with some, particularly I2C. One problem with device tree is that U-Boot has no way of dropping features it does not need or use. For SPL this problem needs to be solved and this series uses a new 'fdtgrep' tool for this. The 45KB Firefly device tree reduces to a 6KB bytes when unused material is removed. SDRAM timings are also in the device tree. This series includes some changes aimed at reduce code size in SPL, including: - dropping alias sequence support (the aliases node) since many boards just use a single UART in SPL - adding a smaller panic() function that does not support printf()-format strings - removing device unbind code which will never be used in SPL There is a large amount of additional work to bring other Rockchip drivers and features into mainline U-Boot, so this is only a start. Changes in v3: - Update clock rate to always be 24MHz - Add device tree bindings for CRU and DMC - Make use of additional features since version 2 - Update README to mention available drivers - Add various new patches to get RK3288 booting to a prompt Changes in v2: - Tidy up license headers and remove SPL #ifdefs - Tidy up license headers and remove SPL #ifdefs - Drop use of CONFIG_USE_PRIVATE_LIBGCC=y - Tidy up license headers and remove SPL #ifdefs Simon Glass (25): rockchip: Add serial support rockchip: Bring in RK3288 device tree file includes and bindings rockchip:

[U-Boot] [PATCH] dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port
by Hans de Goede 06 Aug '15

06 Aug '15

Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

[U-Boot] [PATCH 0/2] ARM: tegra: enable GPU DT node
by Alexandre Courbot 06 Aug '15

06 Aug '15

Tegra124 requires the bootloader to perform VPR initialization, otherwise the GPU cannot be used by the system. Since using the GPU without that initialization results in a hang, the GPU DT node is left disabled, and it is the task of the bootloader to enable it after ensuring it is safe to use the GPU. VPR init is already performed since patch df3443dfa449, but the device tree was left untouched. This patch series performs this last step and prepares the GPU intialization code to receive more code for newer chips. Patch 1 of this series moves the GPU initialization code to a more generic place, since newer chips like T210 require extra steps to initialize the GPU (e.g. WPR setup). It also performs VPR initialization at a later time of the bootloader life, so that we can check the status variable right before booting the kernel and patch the DT accordingly. Patch 2 performs the DT patching using the ft_board_setup() hook.

[U-Boot] board_pci_pre_scan() and board_pci_post_scan()
by Bin Meng 06 Aug '15

06 Aug '15

Hi Simon, With driver model pci conversion on x86 boards, we now missed the call to board_pci_pre_scan() and board_pci_post_scan() which are called in the non-dm path. For example, board_pci_post_scan() in arch/x86/lib/fsp/fsp_common.c is not called to do any work as requested by FSP after pci enumeration. I am not sure where we could insert these call back in the dm. Do you have any possible solution on this? Regards, Bin
