From 34d55be0747ba4452f9611ca88fe21e9d94be266 Mon Sep 17 00:00:00 2001 From: Ed Maste Date: Tue, 15 Aug 2023 18:42:22 -0400 Subject: [PATCH] boot0: add a note about BIOS-supported serial rates We plan to increase the default serial rate to 115200 (see review D36295) but early boot components that use BIOS interfaces do not support higher rates. Add a note to that effect.
