From 6ffd42548bf10cda13a01555ff4fa56d4213cdf2 Mon Sep 17 00:00:00 2001 From: Aidan MacDonald Date: Thu, 22 Dec 2022 19:23:29 +0000 Subject: multiboot: Refactor boot data validation, add version numbers Instead of verifying the CRC before every access of the boot data, verify the CRC once at startup and set a flag to indicate the boot data is valid. Also add a framework to support multiple boot protocol versions. Firmware declares the maximum supported protocol version using a version byte in the boot data header. The bootloader chooses the highest version supported by it and the firmware when deciding what boot protocol to use.
