From f8bf54b4081c3c3d518830df0017a23ec672a841 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Thu, 25 Jun 2009 19:40:28 -0400 Subject: [PATCH] Blackfin: blackstamp: update spi flash settings The latest blackstamp boards can only run the SPI flash at 15MHz before they start to crap out, so lower the max speeds accordingly. The new SPI flash also has different sector requirements, so update the environment sizes as well.
