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
