[U-Boot] [PATCH 4/4] efikamx: update to Efika MX Smarttop and Smartbook boards
Matt Sealey

Wed Aug 22 21:25:41 CEST 2012
This is a rework of a previously submitted patchset and bundles the
main board support and USB support into a single commit.
It requires the patch "mx5: add iomux-mx51.h include"
* Use iomux-mx51.h include to simplify board configuration.
* Simplify LED support (remove efikamx_toggle_led, change lit LEDs).
* Simplify MMC support for CD and WP pin differences.
* Fix broken CPU voltage setting - comment said 1.1V but the code set to
1.2V. It should never have been set to 1.2V even on i.MX51 TO2 and
all available Linux kernels would drop the voltage to 1.1V anyway and
work reliably. This should lower power consumption during the boot
process.
* Function renames for readability.
* Some board identification string changes to match actual product names.
