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.

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.

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.

The back-to-bootrom option is rather unfortunately named
CONFIG_ROCKCHIP_SPL_BACK_TO_BOOTROM
instead of
CONFIG_SPL_ROCKCHIP_BACK_TO_BOOTROM
To make is selectable through CONFIG_IS_ENABLED(ROCKCHIP_BACK_TO_BOOTROM),
we need to rename it. At the same time, we introduce a TPL_ variant of
the option to give us finer-grained control over when it should be used.
This change is motivated by our RK3368 boot process, which returns to
the boot ROM only from the TPL stage, but not from the SPL stage.
