From 741e30e8c2b837dc92ee2eedec5478afdd83a316 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Sun, 14 Apr 2024 16:47:06 +0200 Subject: [PATCH] board: cssi: Read and display MCR board address MCR boards are plugged in racks. The position in the rack can be read in a register. For MCR3000, that's provided by the FPGA so check it is loaded before reading the address. For the other boards, the FPGA is loaded by hardware so it can be read inconditionnaly.
