The FriendlyElec NanoPi R28S is a dual gigabit Ethernet router board
based on the Rockchip RK3528 SoC. It shares most of its design with the
NanoPi Zero2.
The Linux devicetree for the board has been applied to the Rockchip
tree for v7.4, together with a patch that splits the parts shared with
the NanoPi Zero2 into a common rk3528-nanopi.dtsi:
fdb087806e80 ("arm64: dts: rockchip: Split out the common NanoPi RK3528
parts")
c1e23f3425c4 ("arm64: dts: rockchip: Add devicetree for the FriendlyElec
NanoPi R28S")
These are not yet available in devicetree-rebasing, so this series only
contains the U-Boot side for review for now. Patch 3 does not build
until the R28S devicetree is in dts/upstream. Once both commits are in
devicetree-rebasing, I will pick them into dts/upstream with
tools/update-subtree.sh and add them at the start of the next version.
Patch 1 moves the U-Boot specific parts of the NanoPi Zero2 into a
common rk3528-nanopi-u-boot.dtsi, following the split in Linux. The
NanoPi Zero2 u-boot.dtb is identical before and after this patch.
Patch 2 adds a NanoPi RK3528 board target that reads the HW_ID on
SARADC channel 2 to select the FDT in SPL and set fdtfile, in the same
way as the Radxa ROCK 2 board target, and moves the NanoPi Zero2 to it.
Patch 3 adds the NanoPi R28S to that board target, so that
nanopi-zero2-rk3528_defconfig supports both boards.
nanopi-zero2-rk3528 was build-tested with the devicetree files from
v7.4-armsoc/dts64 copied into dts/upstream; the resulting FIT contains
both the Zero2 and the R28S FDT.

Changes in v2:
- Add a common NanoPi RK3528 board target that selects the FDT using
the HW_ID on SARADC channel 2, instead of adding a new defconfig for
the R28S (Jonas)
- Add Jonas Karlman as reviewer for the R28S.
