Subject: [PATCH v2 3/3] Documentation: riscv: Update boot image header since EFI stub is supported
Date: Wed, 21 Jun 2023 09:22:34 +0200 [thread overview]
Message-ID: <20230621072234.9900-3-alexghiti@rivosinc.com> (raw)
In-Reply-To: <20230621072234.9900-1-alexghiti@rivosinc.com>
The EFI stub is supported on RISC-V so update the documentation that
explains how the boot image header was reused to support it.

Notes
=====
-- This header can also be reused to support EFI stub for RISC-V in future. EFI
- specification needs PE/COFF image header in the beginning of the kernel image
- in order to load it as an EFI application. In order to support EFI stub,
- code0 should be replaced with "MZ" magic string and res3(at offset 0x3c) should
- point to the rest of the PE/COFF header.
