Here are some basic OMAP test results for Linux v3.7-rc3.
Logs and other details at:
http://www.pwsan.com/omap/testlogs/test_v3.7-rc3/20121028162003/
Passing tests
-------------
Boot to userspace: 2420n800, 3517evm, 3530es3beagle, 3730beaglexm, 37xxevm,
4430es2panda, 5912osk, am335xbone
PM ret/off, suspend + dynamic idle: (none)
Failing tests: fixed by posted patches
--------------------------------------
Boot tests:
* 2430sdp: vfp_reload_hw oops during MMC initialization
- Kernel attempts to save FP registers that don't exist; fix posted:
- http://www.spinics.net/lists/arm-kernel/msg200646.html
- added to rmk's patch system as 7566/1
* AM335x Beaglebone: omap2plus_defconfig kernels don't boot
- Due to GPMC missing support for DT
- Temporary workaround at http://www.spinics.net/lists/arm-kernel/msg200787.html
- May be fixed now, pending retest:
- http://marc.info/?l=linux-omap&m=135082257727502&w=2
PM tests:
* 3530es3beagle, 37xxevm, 3730beaglexm: I2C fails during resume from suspend
- Causes MMC to become unusable since regulators are not reenabled
- Caused by RT throttling
- Fixed by http://www.spinics.net/lists/arm-kernel/msg202224.html
- Patch in rmk's patch system as 7565/1
* 37xx EVM: CORE not entering dynamic off-idle
- Dynamic retention-idle seems to work; system suspend to off works
- Happens on both MMC root and NFS root
- Can be detected by comparing the CORE off/ret counts from
/debug/pm_debug/count before & after serial autosuspend occurs
- Fixed by http://marc.info/?l=linux-arm-kernel&m=135127961519817&w=2
* 3530es3beagle: hangs during off-mode dynamic idle test
- Appears to be caused by commit 6c31b2150ff96755d24e0ab6d6fea08a7bf5c44c:
- http://marc.info/?l=linux-omap&m=135075364705188&w=2
- Fixed by http://www.spinics.net/lists/arm-kernel/msg202116.html
Other:
* 2420N800: powers down 30 seconds after boot
- Presumably due to missing CBUS patches for watchdog control
- http://lkml.org/lkml/2012/9/3/265
* 4430es2panda: omap_hwmod: mcpdm: cannot be enabled for reset (3)
- clock source is from an external I2C-controlled source
- must skip reset until the switchover to hwmod late init
- http://www.spinics.net/lists/arm-kernel/msg178138.html
Failing tests: needing investigation
------------------------------------
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 with NFS root
- Likely some Kconfig, board file, and PM issues with EMAC
* CM-T3517: boot hangs with MMC boot
- Due to missing MMC setup in board file
* 4460pandaes: boot fails early
- Appears to be due to X-loader problems here
- Need to note the X-loader version so we know it's broken
* 3530ES3 Beagle: I2C timeouts during userspace init
- Intermittent, appears on 5 out of 6 boots here
- Aaro Koskinen observes this also on N900
- Appears to be caused by commit 3db11feffc1ad2ab9dea27789e6b5b3032827adc
- http://marc.info/?l=linux-arm-kernel&m=135071372426971&w=2
PM tests:
* 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
- Pending re-test
Other:
* 4430es2panda: omap_hwmod: l3_instr: _wait_target_disable failed
- Unknown cause; could be due to the lack of hierarchical enable/disable
in hwmod code
- Jon Hunter reports this does not appear with the same X-loader/bootloader
on his 4430ES2.3 Panda, so could be ES-level dependent

The 17k increase in the rmk_omap3430_ldp_oldconfig text appears to be due
to the automatic selection of CONFIG_PINCTRL by 'make oldnoconfig', new in
v3.7-rc3.
