From 305c0cafaa2fe7d766918898692971b70259b4ac Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Sat, 3 Dec 2016 17:04:06 -0600 Subject: drivers/spi: provide a mechanism to obtain the SPI flash boot device The MRC cache wants to be able to access the SPI flash boot device. Allow an easy way to provide that so that there isn't duplicate spi_flash objects representing the same device.
