From 3cedc97479ff44cdc00485de7517a833e3dfb630 Mon Sep 17 00:00:00 2001 From: Atish Patra Date: Mon, 6 May 2019 17:49:39 -0700 Subject: RISCV: image: Add booti support This patch adds booti support for RISC-V Linux kernel. The existing bootm method will also continue to work as it is. It depends on the following kernel patch which adds the header to the flat Image. Gzip compressed Image (Image.gz) support is not enabled with this patch. https://patchwork.kernel.org/patch/10925543/ Tested on HiFive Unleashed and QEMU.
