From a745a622434d9c3ff6505125b37fd6828ecadb87 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Fri, 5 Sep 2008 00:34:50 +0100 Subject: [ARM] 5240/1: AT91: eeproms on sam9260ek, sam9263ek The at91sam9260 and at91sam9263 EK boards have 64 KiB I2C EEPROMs. This patch declares them in the board init code so the new at24 driver will use them.
