From f0d1246ed7cb5a88522244c596d7ae7e6f161283 Mon Sep 17 00:00:00 2001 From: Haavard Skinnemoen Date: Wed, 27 Jun 2007 13:34:26 +0200 Subject: atmel_mci: Use 512 byte blocksize if possible Instead of always using the largest blocksize the card supports, check if it can support smaller block sizes and use 512 bytes if possible. Most cards do support this, and other parts of u-boot seem to have trouble with block sizes different from 512 bytes. Also enable underrun/overrun protection.
