From 488d89afb88af5f148c7c7cf97ac382a0537b4f7 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 5 Nov 2020 10:33:46 -0700 Subject: [PATCH] x86: zimage: Add silent-console processing At present zimage does its own command-line processing and does not support the 'silent console' feature. There doesn't seem to be any good reason for this. Add support for silent console to zimage.
