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 changes to split SPL/TPL for the RK3368, I apparently missed
some needed adjustments to the RK3188 Kconfig and rock_defconfig.
This fixes build-issues for the rock board after applying the RK3368
enablement (and SPL/TPL) set that resulted from TPL_SERIAL_SUPPORT,
TPL_ROCKCHIP_BACK_TO_BROM and TPL_TINY_MEMSET being separate symbols
now.

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
and RK3399... all of these read some of the tuning/setup/timing
parameters from the device-tree.

At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

The Rock is a RK3188 based single board computer by Radxa.
Currently it still relies on the proprietary DDR init and
cannot use the generic SPL, but at least is able to boot
a linux kernel and system up to a regular login prompt.

Right now we're setting the wrong value of 0 as base in the ram_info struct,
which is obviously wrong for the rk3188. So instead set the correct value
we already have in CONFIG_SYS_SDRAM_BASE.

Commit c67c8c604b ("board_init.c: Always use memset()") dropped the naive
memset alternative from board_init_f_init_reserve.
So activate CONFIG_TPL_LIBGENERIC for that common memset implementation.
We cannot use the ARCH-specific memset, as that would incur 200bytes of
additional TPL size, space we do not have.

The sdram controller blocks are very similar to the rk3288 in utilizing
memory scheduler, Designware uPCTL and Designware PUBL blocks, only
limited to one bank instead of two.
There are some minimal differences when setting up the ram, so it gets
a separate driver for the rk3188 but reuses the driver structs, as there
is no need to define the same again.
More optimization can happen when the modelling of the controller parts
in the dts actually follow the hardware layout hopefully at some point
in the future.
