From d70bf7cc219f8478e8336f60542a50c078bf531b Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Mon, 20 Apr 2015 15:24:19 -0500 Subject: [PATCH] cbmem_console: fix it for x86 The Kconfig options pertaining cbmem console in the preram environment no longer make sense with the linker script changes. Remove them and their usage within cbmem_console.
