commit 5683bc17ab2ccf3906d805cebc1837957c79ce3a Author: Patrick Georgi pgeorgi@chromium.org Date: Sat Jan 28 15:26:43 2017 +0100
ddr3 spd: Rename read_spd_from_cbfs() to read_ddr3_spd_from_cbfs()
Since it checks for DDR3 style checksums, it's a more appropriate name. Also make its configuration local for a future code move.
