Hi, -----Original Message----- From: Lothar Rubusch <[email protected]> Sent: Saturday, October 26, 2024 11:52 PM To: [email protected]; [email protected]; [email protected]; [email protected]; Chee, Tien Fong <[email protected]>; [email protected] Cc: [email protected]; [email protected]; [email protected]; Lim, Jit Loon <[email protected]>; [email protected]; [email protected] Subject: [PATCH v4 03/11] ARM: dts: socfpga: add Mercury+ AA1 for u-boot dts
Introduce u-boot specific device-tree files for Enclustra Mercury+ AA1 SoMs (Intel/arria10). Generic device-tree fragments for linux and U-boot shall be provided in dts/upstream. The selection of the generic device-tree fragments depends on a selected boot-mode and a selected carrier board. On Intel/Arria10 a handoff setup is needed for initialization of various clock / pinmux / DRAM settings only used by U-Boot provided by the current patch.
