From 48fff4bc2825f4a90924769f66d3b1314bdde2b8 Mon Sep 17 00:00:00 2001 From: Martin Kepplinger Date: Mon, 7 Jan 2019 08:22:35 +0100 Subject: [PATCH] x230: skip ram voltage check This simplifies setup by remove the unneeded RAM voltage checking. According to the spec, DDR3L RAM has to work using 1.5V, see https://en.wikipedia.org/wiki/DDR3_SDRAM#DDR3L_and_DDR3U_extensions. Coreboot simply doesn't always implement changing voltage, which can never prevent RAM from working though.
