From d3f34e752dd432eb75e50b2f2ab44d0849b3deef Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Fri, 10 Jul 2015 00:04:23 +0200 Subject: [PATCH] arm: socfpga: spl: Add support for booting from SD/MMC Add code and configuration options to support booting from RAW SD/MMC card as well as for ext4/vfat filesystems. Enable support for booting from SD/MMC card, but don't enable the filesystem support just yet to retain compatibility with old SoCFPGA card format.
