From 200aa7c5b1b1f4c74412893cf7231a12e2702463 Mon Sep 17 00:00:00 2001 From: David Hendricks Date: Fri, 21 Mar 2014 17:09:29 -0700 Subject: [PATCH] x86: Set BOOT_MEDIA_SPI_BUS BOOT_MEDIA_SPI_BUS is a Kconfig variable used on some ARM-based platforms to set up CBFS media. It turns out it can also be helpful for setting up the eventlog which is intended to reside on the same SPI flash as CBFS. Setting it for x86 will allow us to remove an assumption about which SPI bus is used for this flash device. Long term this can go away as we come up with a better abstraction for the eventlog's backing store. This is only intended to help us get from here to there.
