Fabio Estevam - May 3, 2013, 2 p.m.
From: Fabio Estevam <fabio.estevam@freescale.com>

Change MUX_CONFIG_EMI to use the same drive strength as the bootlets code from
Freescale, which results in much better stability.

Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
---
Changes since v3:
- None
Changes since v2:
- Only change the drive strength
Changes since v1:
