[PATCH 3/3] [ARM] msm: add minimal board file for HTC Dream device

Brian Swetland
2009-06-18T00:34:56Z

This is just enough to get the device booting and serial console
working. Sufficient for debugging further MSM7k/Dream Support.
This will support HTC Dream / T-Mobile G1 / Android ADP1 (which
are all the same hardware, known as "trout" to the ARM machine
database).
