[PATCH v3 1/2] arm: rmobile: Add RZ/G2M SoC

Biju Das
Add CPU and PRR IDs for R8A774A1(a.k.a RZ/G2M) SoC.

RZ/Gx SoC's are identical to R-Car SoC's apart from some automotive
peripherals and they also share the same PRR CPU ID's.

For example the RZ/G2M SoC has the same PRR ID 0x52 as R-Car M3W SoC.

For RZ/G2 SoC identification compatible string from TFA are matched
against the list of compatible strings in struct tfa_cpuinfo.

Also sorted the header alphabetically.

[PATCH v3 2/2] arm: rmobile: Add HopeRun HiHope RZ/G2M board support

Biju Das
In reply to this post by Biju Das
The HiHope RZ/G2M board from HopeRun consists of main board
(HopeRun HiHope RZ/G2M main board) and sub board(HopeRun
HiHope RZ/G2M sub board). The HiHope RZ/G2M sub board sits
below the HiHope RZ/G2M main board.

DTS files apart from r8a774a1-hihope-rzg2m-u-boot.dts and
r8a774a1-u-boot.dtsi have been imported from Linux kernel 5.9-rc4 commit
f4d51dffc6c0 ("Linux 5.9-rc4")

This patch adds the required board support to boot HopeRun HiHope
RZ/G2M board.
