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.

With the new dev_read functions available, we can convert the rockchip
architecture-specific drivers and common drivers used by these devices
over to the dev_read family of calls.
This covers the DRAM controller initialisation for the RK3188, RK3288

The RK3399 is capable of driving DDR3 at 933MHz (i.e. DDR3-1866),
if the PCB layout permits and appropriate memory timings are used.
This changes the sanity checks to allow a DTS to request DDR3-1866
operation.

It's caused by the absence of "{ }" in syscon_rk3399.c
,which will lead to memory overflow like below.According
to Sysmap file ,we can find the function buck_get_value
of rk808 is just follow the compatible struct,the pointer
"of_match" point to "buck_get_value",but it is not a
struct and don't have member of compatible, In this case,
system crash. So,on the face, it looks like that rk808 is
guilty.but he is really innocent.

The RK3399-Q7 SoM is a Qseven-compatible (70mm x 70mm, MXM-230
connector) system-on-module from Theobroma Systems, featuring the
Rockchip RK3399.
It provides the following feature set:
* up to 4GB DDR3
* on-module SPI-NOR flash
* on-module eMMC (with 8-bit interace)
* SD card (on a baseboad) via edge connector
* Gigabit Ethernet w/ on-module Micrel KSZ9031 GbE PHY
* HDMI/eDP/MIPI displays
* 2x MIPI-CSI
* USB
- 1x USB 3.0 dual-role (direct connection)
- 2x USB 3.0 host + 1x USB 2.0 (on-module USB 3.0 hub)
* on-module STM32 Cortex-M0 companion controller, implementing:
- low-power RTC functionality (ISL1208 emulation)
- fan controller (AMC6821 emulation)
- USB<->CAN bridge controller
Note that we use a multi-payload FIT image for booting and have
Cortex-M0 payload in a separate subimage: we thus rely on the FIT
image loader to put it into the SRAM region that ATF expects it in.
