From 766b16fe180087d8c59a79a4f6a92d1a500fa524 Mon Sep 17 00:00:00 2001 From: Marc Jones Date: Mon, 29 Oct 2012 05:24:02 +0000 Subject: ahci: Perform SATA flush after disk write. Writes in u-boot are so rare, and the logic to know when is the last write and do a flush only there is sufficiently difficult. Just do a flush after every write. This incurs, usually, one extra flush when the rare writes do happen.
