7f3eec03d5 rockchip: rk3036: add board_debug_uart_init()
Use board_debug_uart_init() for UART iomux init instead of
do it in board_init_f, and move the function to soc file so
that we can find all the soc/board setting in soc file and
use a common board file.

b1b449bf1f rockchip: correct ARCH_SOC name
The ARCH_SOC name default as 'rockchip' and we put all the
header file in 'arch/arm/include/asm/arch-rockchip/', but
the 'rockchip' is not the SOC name, let's correct it after
we update all the source file.

All the source code of sdram_rk3036.c are from Rockchip, update the
copyright to owned by Rockchip.

Because rockchip may use this copy of code both for open source
project and internal project, update the license to use both
GPL2.0+ and BSD-3 Clause.

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.

b47ea79219 rockchip: add option to change method of loading u-boot
If we would like to boot from SD card, we have to implement mmc driver
in SPL stage, and get a slightly large SPL binary. Rockchip SoC's
bootrom code has the ability to load spl and u-boot, then boot.

If CONFIG_ROCKCHIP_SPL_BACK_TO_BROM is enabled, the spl will return to
bootrom in board_init_f(), then bootrom loads u-boot binary.

Loading sequence after rework:
bootrom ==> spl ==> bootrom ==> u-boot

1163625898 Rename reset to sysreset
The current reset API implements a method to reset the entire system.
In the near future, I'd like to introduce code that implements the device
tree reset bindings; i.e. the equivalent of the Linux kernel's reset API.
This controls resets to individual HW blocks or external chips with reset
signals. It doesn't make sense to merge the two APIs into one since they
have different semantic purposes. Resolve the naming conflict by renaming
the existing reset API to sysreset instead, so the new reset API can be
called just reset.
