From ad6f87d61202984e7604a35b6ce5babee614e676 Mon Sep 17 00:00:00 2001 From: Felix Held Date: Tue, 12 Oct 2021 23:35:48 +0200 Subject: soc/amd/cezanne,picasso/uart: implement read_resource Implement the read_resources function for the UART devices so that the resource allocator knows about their fixed MMIO resources when enabled. TEST=UART still works on Mandolin.
