From 019b39b7366e5591949f6d41aeac474b632be704 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Wed, 3 May 2023 08:38:16 +0200 Subject: [PATCH] board: cssi: Load CMPC885's motherboard FPGA earlier In order to know the motherboard type earlier, perform I/O ports initialisation and FPGA loading in board_early_init_f() instead of board_early_init_r(). This is needed to be able to load mpc8xx CPM microcode base on motherboard type and before starting to use the CPM. Console is not available yet so remove the printfs.
