[U-Boot] [PATCH v2 0/8] ARMV7: Enhance support for OMAP4

[Steve Sakoman]

This is version 2 of the patch set.  It incorporates all feedback to date.

This patch series adds support for:
 - pad mux initialization
 - OMAP4 TWL6030 companion chip initialization
 - usb driver and gadget support
 
It also fixes issues in the udelay implementation and the OMAP I2C
driver as well as tweaks the default environment.
 
These patches were tested on Panda and OMAP4430 SDP as well as on
the Gumstix Overo to verify that there were no regressions on OMAP3.

Steve Sakoman (8):
  ARMV7: Add pad mux support for OMAP4
  ARMV7: Fix udelay for OMAP4
  ARMV7: Modify i2c driver for more reliable operation on OMAP4
  ARMV7: Add support for the TWL6030 I2C power chip used in OMAP4
    systems
  ARMV7: Restructure omap3 musb driver to allow code sharing between
    OMAP3 and OMAP4
  ARMV7: Enable musb driver and usbtty on OMAP4430 SDP
  ARMV7: Enable musb driver and usbtty on OMAP4 Panda
  ARMV7: Update default environment for OMAP4 boards
