[U-Boot] [PATCH 0/7] Tegra2: USB Host Support patch series

[Simon Glass]

This patch series adds USB host support to Tegra2. It has been tested on
Seaboard.

Since the Tegra2 includes a vast number of registers it is critical that we
make it as easy and error-free as possible to write code which accesses those
registers. So a simple bitfield access mechanism is provided which mirrors
the notation in many datasheets (16:12 means bits 16 downto 12).

Support is provided for clock and pinmux functions which are used in USB and
will be used commonly in future patches. A microsecond timer is required for
PLL setup timing.

Finally, as a motivation for all this effort, network booting is enabled for
Seaboard. A previous patch containing full documentation want sent to the
list on 13-Apr-11 (Add documentation for USB Host Networking).

These patches are prepared against u-boot-arm.git/master.
