5b67d7010b rockchip: rk3188: move sdram driver to driver/ram
Since we have CONFIG_RAM framwork and its driver folder, move the driver
into it.

96b9082c64 rockchip: rk3188: rock: adjust for SPL/TPL split
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.

8f1034e627 rockchip: dm: convert fdt_get to dev_read
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.

da409ccc4a dm: core: Replace of_offset with accessor (part 2)
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.

47197682ef rockchip: rk3188: Add Radxa Rock board
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.

3408509f6f rockchip: rk3188: sdram: Set correct sdram base
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.

3c732de9bf rockchip: rk3188: enable TPL_LIBGENERIC for generic memset
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.

3e747197b1 rockchip: rk3188: Add sdram driver
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.
