From 4082fce92498a64e5e543ad53a1ed5a5c02a64d1 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 21 Jan 2016 19:43:53 -0700 Subject: dm: i2c: Allow muxes to be enabled for SPL separately Since I2C muxes are seldom needed in SPL, and the code for this increases the size somewhat, add a separate option to enable I2C muxes for SPL.
