Subject: [Buildroot] [PATCH 1/2] boot/sun20i-d1-spl: new package
Date: Fri,  5 Nov 2021 13:38:46 +0100	[thread overview]
Message-ID: <20211105123848.6356-1-peter@korsgaard.com> (raw)

U-Boot does not yet have SPL code to initialize the DDR controller on the
Allwinner D1 - So instead package the sun20i-d1-spl bootloader, which is
based on boot0 from the Allwinner BSP with some modifications to build it
separately from the BSP and boot mainline U-Boot as explained on the
linux-sunxi wiki:

https://linux-sunxi.org/Allwinner_Nezha
