From: Hai Pham Date: Tue, 2 Dec 2025 18:34:14 +0000 (+0100) Subject: arm64: renesas: Add Renesas R-Car Gen5 infrastructure X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e84a0bbefe19496b31b21c74133eedeefd1cc11c;p=pandora-u-boot.git arm64: renesas: Add Renesas R-Car Gen5 infrastructure Add initial changes to support Renesas R-Car Gen5 SoC. Introduce Kconfig entries, architecture headers and PRR IDs for Renesas R-Car Gen5 and R-Car X5H R8A78000 SoC. Add Makefile change to produce u-boot-elf.srec with correct offset for installation tooling. Update MAINTAINERS entry to cover both r8a77nnn and r8a78nnn .
