From 18238c442866a6ae93533e2421a6f44bc9e57ac6 Mon Sep 17 00:00:00 2001 From: Zoltan HERPAI Date: Sat, 23 Apr 2022 19:06:28 +0200 Subject: [PATCH] firmware-utils: ptgen: add SiFive-related GUID types Add patch until it gets accepted in firmware-utils upstream. The SiFive RISC-V SoCs use two special partition types in the boot process. As a first step, the ZSBL (zero-stage bootloader) in the CPU looks for a partition with a GUID of 5B193300-FC78-40CD-8002-E86C45580B47 to load the first-stage bootloader - which in OpenWrt's case is an SPL image. The FSBL (SPL) then looks for a partition with a GUID of 2E54B353-1271-4842-806F-E436D6AF6985 to load the SSBL which is usually an u-boot. With ptgen already supporting GPT partition creation, add the required GUID types and name them accordingly to be invoked with the '-T ' parameter.
