Since this includes support for OCOTP on this SoC, the following hunks should
also be added:


doc/README.mxc_ocotp:
---
 on MXC
 
 This IP can be found on the following SoCs:
+ - Vybrid MVF600,
  - i.MX6.
 
 Note that this IP is different from albeit similar to the IPs of the same name
---


doc/README.mvf600:
---
+U-Boot for Freescale Vybrid MVF600
+
+This file contains information for the port of U-Boot to the Freescale Vybrid
+MVF600 SoC.
+
+1. CONVENTIONS FOR FUSE ASSIGNMENTS
+-----------------------------------
+
+1.1 MAC Address: It is stored in fuse bank 4, with the 16 msbs in word 2 and the
+    32 lsbs in word 3.
---


You can also add the definition of the fuses for UID if any, like uid_low/high
in struct fuse_bank0_regs in arch/arm/include/asm/arch-mx6/imx-regs.h.
