[PATCH v8] arm: rmobile: Add HopeRun HiHope RZ/G2M board support
Biju Das
biju.das.jz at bp.renesas.com
Sun Jan 17 21:20:14 CET 2021
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.
This patch adds the required board support to boot HopeRun HiHope
RZ/G2M board.
