From db7dd8109cad3ccdea23d2eebafe588f2ab585d6 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Tue, 31 Jul 2012 10:50:01 -0700 Subject: am33xx: Rework pinmux functions - Move definition of the EEPROM contents to - Make some defines a little less generic now. - Pinmux must be done by done by SPL now. - Create 3 pinmux functions, uart0, i2c0 and board. - Add pinmux specific to Starter Kit EVM for MMC now.
