[U-Boot] [PATCH 00/12] tegra: nyan-big: Support chainloading and add documentation
by Simon Glass 09 Jul '17

09 Jul '17

Every now and then someone wants to chain-load U-Boot on a Chromebook. The procedure is not very complicated but there are some oddities. This series updates a few things with allow U-Boot to start on nyan-big in this way and adds documentation on how to do it. This provides a central place where the procedure on different devices can be documented. Simon Glass (12): arm: arm720t: Support CONFIG_SKIP_LOWLEVEL_INIT_ONLY tegra: Init clocks even when SPL did not run tegra: dts: Add cros-ec SPI settings arm: Rename HCTR to HTCR arm: Don't try to support CONFIG_ARMV7_LPAE on ARMv4T arm: Disable LPAE if not enabled tegra: spi: Wait a little after setting the clocks tegra: nyan-big: Enable the dhrystone benchmark tegra: video: Don't power up the SOR twice tegra: Enable CP15 init tegra: clock: Avoid a divide-by-zero error README: Add instructions for chain-loading U-Boot arch/arm/cpu/arm720t/start.S | 6 +- arch/arm/dts/tegra124-nyan-big-u-boot.dtsi | 9 ++ arch/arm/include/asm/arch-tegra/clock.h | 3 + arch/arm/lib/cache-cp15.c | 13 +- arch/arm/mach-tegra/board2.c | 3 + arch/arm/mach-tegra/clock.c | 10 +- arch/arm/mach-tegra/tegra124/clock.c | 18 +++ configs/nyan-big_defconfig | 2 + doc/README.chromium | 222 +++++++++++++++++++++++++++ doc/chromium/devkeys/kernel.keyblock | Bin 0 -> 1208 bytes doc/chromium/devkeys/kernel_data_key.vbprivk | Bin 0 -> 1199 bytes drivers/spi/tegra114_spi.c | 1 + drivers/video/tegra124/sor.c | 9 ++ include/configs/tegra-common-post.h | 2 +- 14 files changed, 292 insertions(+), 6 deletions(-) create mode 100644 doc/README.chromium create mode 100644 doc/chromium/devkeys/kernel.keyblock create mode 100644 doc/chromium/devkeys/kernel_data_key.vbprivk -- 2.13.0.303.g4ebf302169-goog

[U-Boot] [PATCH v2] mkimage: fix display of image types list
by Baruch Siach 07 Jul '17

07 Jul '17

Since commit 5b9d44df2307f (mkimage: Display a better list of available image types) mkimage usage text suggest to "use -T to see a list of available image types". Unfortunately, commit 02221f29deb8 (mkimage: Convert to use getopt()) broke that feature, because getopt() fails when -T has no option argument. Add a pseudo image type name 'list' that lists all image types. Update the usage text accordingly.
