OMAP baseline test results for v3.6-rc7

[Paul Walmsley]

Here are some basic OMAP boot and power management test results for 
v3.6-rc6:

   http://www.pwsan.com/omap/testlogs/test_v3.6-rc6/20120918101040/

Some observations:

Boot tests:

* CM-T3517: L3 in-band error with IPSS during boot
  - Cause unknown but see 
http://marc.info/?l=linux-omap&m=134833869730129&w=2
  - Longstanding issue; does not occur on the 3517EVM

* 3517EVM & CM-T3517: boot hangs               
  - Probably due to the use of NFS root; there are likely some Kconfig,
    board file, and PM issues with EMAC

PM tests:

* 37xx EVM: CORE not entering dynamic off-idle
  - Cause unknown; dynamic retention-idle seems to work; system suspend to 
    off works

* 3730 Beagle XM: does not serial wake from off-idle suspend when console
  UART doesn't clock gate ("debug ignore_loglevel")
  - Not shown in the current test logs; cause unknown

* 4430ES2 Panda: UART corruption during long transmit buffers
  - Presumably due to either a missing hardware workaround or a bug in
    the OMAP serial driver

Other:

* RCU stall messages appear if boards are booted into a minimal userspace
  and left to sit for a few minutes
