Subject: [PATCH v2 2/3] m68k: m680x0: Initialise the debug uart
Date: Mon, 9 Mar 2026 19:51:09 +0900 [thread overview]
Message-ID: <20260309105110.672832-2-daniel@0x0f.com> (raw)
In-Reply-To: <20260309105110.672832-1-daniel@0x0f.com>
Once the stack is ready we can init the debug uart to help
with debugging so do that.
