From 0a9b73a13e3440994d4b245ffdc86c51361a296d Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sat, 24 Sep 2016 18:20:08 -0600 Subject: spl: spi: Move the generic SPI loader into common/spl All the other SPL loaders are in this directory, so move the SPI one in there too. There are two board-specific SPI loaders (fsl and sunxi). These remain in the drivers/mtd/spi directory, since they do not contain generic code.
