rockchip: Add support for chromebook_bob

2019-02-01T15:59:13Z

Bob is a 10-inch chromebook produced by Asus. It has two USB 3.0 type-C ports, 4GB of SDRAM, WiFi and a 1280x800 display. It uses its USB ports for both power and external display. It includes a Chrome OS EC (Cortex-M3) to provide access to the keyboard and battery functions. Support so far includes only: - UART - SDRAM - MMC, SD card - Cros EC (but not keyboard) Not included: - Keyboard - Display - Sound - USB - TPM Bob is quite similar to Kevin, the Samsung Chromebook Plus, but support for this is not provided in this series.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini

rockchip: rk3188: use boot0 hook to load up SPL in 2 steps

2017-11-21T22:57:22Z

For the RK3188, the BROM will attempt to load up the first stage image (SPL for the RK3188) in two steps: first 1KB to offset 0x800 in the SRAM and then the remainder to offset 0xc00 in the SRAM. It always enters at 0x804, though. With this changeset, the RK3188 boot removes the TPL (stub) stage and builds a single SPL binary that utilizes the early back-to-bootrom via the boot0-hook. Consequently, the passing of the saved boot params via pmu->os_reg[2] is also removed. Signed-off-by: Philipp Tomsich
