From 3cc157e2e3c80027c69819f82d8bfe37bfb04049 Mon Sep 17 00:00:00 2001 From: Peter Korsgaard Date: Sat, 8 Oct 2022 20:40:16 +0200 Subject: [PATCH] configs/visionfive_defconfig: new defconfig Add a defconfig for the Starfive VisionFive board, a board built around the Starfive JH7100 RISC-V 64bit SoC (same as Beaglev). This board comes with functional lowlevel and U-Boot bootloaders in SPI flash. The defconfig reuses these and only builds a (6.0 based) kernel and rootfs. The factory shipped U-Boot is hard coded to look at MMC partition 3 and misses some variables, so we provide a uEnv.txt to fix that up, based on what is done in provided Fedora image.
