acea123825 rockchip: rk322x: use ARM arch timer instead of rk_timer
We prefer to use ARM arch timer instead of rockchip timer, so that
we are using the same timer for SPL, U-Boot and Kernel, which will
make things simple and easy to track to boot time.

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.

This is workaround for issue we can't get correct size for 4GB ram
in 32bit system and available before we really need ram space
out of 4GB, eg.enable ARM LAPE(rk3288 supports 8GB ram).
The size of 4GB is '0x1 00000000', and this value will be truncated
to 0 in 32bit system, and system can not get correct ram size.
Rockchip SoCs reserve a blob of space for peripheral near 4GB,
and we are now setting SDRAM_MAX_SIZE as max available space for
ram in 4GB, so we can use this directly to workaround the issue.

It consists of Rock960 (Consumer Edition) and Ficus (Enterprise Edition)

Below are some of the key differences between both Rock960 and Ficus
boards:

1. Different host enable GPIO for USB
2. Different power and reset GPIO for PCI-E
3. No Ethernet port on Rock960

The common board support will be utilized by both boards. The device
tree has been organized in such a way that only the properties which
differ between both boards are placed in the board specific dts and
the reset of the nodes are placed in common dtsi file.

The RK3399 SPL has two cases that may end in a hard-stop: if either
the pinctrl can not be initialised or if the DRAM fails to initialise.
Both have previously not triggered an error message unless DEBUG was

This converts both error messages to be printed using pr_err() to
ensure that some output points to the cause of the hard-stop.

This also breaks the early uart setup, as the iomux for uart2 are needed.
To fix that just put the tiny amount of needed iomux definitions next to

e5f2ecc750 rockchip: rk3399: inject 'u-boot, spl-boot-device' for next-stage
This implements the new 'spl_perform_fixups' hook for RK3399-based
boards and injects the /chosen/u-boot,spl-boot-device with an ofpath
corresponding to the boot device used.

The intended usage is for the full U-Boot stage to evaluate this in
scripts and then adapt its boot-order when using distro-boot.

8a65bd6372 fastboot: Rename fb_set_reboot_flag to fastboot_set_reboot_flag
Rename fb_set_reboot_flag to fastboot_set_reboot_flag so it matches
all other fastboot code in the global name space. Fix the guards around
them so that they're dependent on FASTBOOT, not just USB_FUNCTION_FASTBOOT.

Move the weak implementation of fastboot_set_reboot_flag to fb_common.c
so we can call it from non-USB fastboot code.

acf1500138 arm: v7: Kconfig: Rename CPU_V7 as CPU_V7A
Currently CPU_V7 kconfig symbol supports only ARMv7A architectures under
armv7 folder. This led to a misconception of creating separate folders
for armv7m and armv7r. There is no reason to create separate folder for
other armv7 based architectures when it can co-exist with few Kconfig
symbols.

As a first step towards a common folder, rename CPU_V7 as CPUV7A. Later
separate Kconfig symbols can be added for CPU_V7R and CPU_V7M and
can co exist in the same folder.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.
