Subject: [PATCH 0/3] OMAP3: add ES3.1 support; disable USBTLL SAR < ES3.1

Hello Russell,

this series adds OMAP3 ES3.1 support, including boot-time TAP detection and
omap_chip updates.  It also blocks USBTLL hardware save-and-restore (SAR)
support on revisions < ES3.1, due to chip errata.

To do this, the semantics of the omap_chip system had to be altered slightly.
Previously, CHIP_IS_OMAP3430ES2 would also evaluate true on ES3 devices.
Now it will only evaluate to true on ES2.x devices.  Features that are
present on revisions >= ES2 are now marked with CHIP_GE_OMAP3430ES2 ("GE"
meaning "greater than or equal to").

This series obsoletes patch B 06, and is intended to be applied after
all of the previously-sent patches.

Tested on BeagleBoard ES2.1.

- Paul
