Subject: [PATCH v2 1/4] riscv: t-head: licheepi4a: initial support added
Date: Sat,  8 Jul 2023 19:24:32 +0800	[thread overview]
Message-ID: <20230708112435.23583-2-dlan@gentoo.org> (raw)
In-Reply-To: <20230708112435.23583-1-dlan@gentoo.org>

Add support for Sipeed's Lichee Pi 4A board which based on T-HEAD's
TH1520 SoC, only minimal device tree and serial console are enabled,
so it's capable of chain booting from T-HEAD's vendor u-boot.
