Looks like a few messages were missed, so here's an updated version, along 
with the size data.

Here are some basic OMAP test results for Linux v3.10-rc1.

Failing tests: fixed by posted patches
--------------------------------------

Boot:

* ARMv6 OMAPs don't boot with omap2plus_defconfig
  - missing Kconfig 
  - http://marc.info/?l=linux-omap&m=136872761502689&w=2

* 3517EVM & CM-T3517: boot hangs with MMC root
  - Possibly fixed by https://lkml.org/lkml/2013/5/5/6


Failing tests: needing investigation
------------------------------------

Boot tests:

* 3517EVM & CM-T3517: boot hangs with NFS root
  - Likely some Kconfig, board file, and PM issues with EMAC
  - Longstanding bug
  - Not currently part of the automated test suite

* 37xx EVM: boot fails
  - Cause unknown

Boot warnings:

* 2420N800: failed to get counter_32k resource
  - "omap2_sync32k_clocksource_init: failed to get counter_32k resource"
  - Cause unknown

* 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

* 3730 Beagle XM, 3530 Beagle, 3517EVM, CM-T3517: {dmic,mcpdm} lookup failure
  - Cause unknown
  - These IP blocks don't exist on OMAP3xxx/AM35xx chips

* 3730 Beagle XM, am335xbone, CM-T3517: uart4_rx.uart4_rx mux failure
  - Cause unknown

PM tests:

* 2430sdp: power domains not entering retention
  - Cause unknown

* 3730 Beagle XM: does not serial wake from off-idle suspend when console
  UART doesn't clock-gate ("debug ignore_loglevel")
  - Cause unknown
  - Not yet part of the automated test suite
  - Re-tested at v3.7; still failing:
    http://www.pwsan.com/omap/transcripts/20121211-3730beaglexm-3.7-pm-offmode-fail-debug.txt

* 4430es2panda: pwrdm state mismatch on CAM, DSS

* 4430es2panda: CORE, TESLA, IVAHD, L3INIT didn't enter target state
  - Probably due to lack of reset code for M3, DSP, SL2IF, FSUSB
    per discussion with Tero Kristo
  - Likely dependent on the bootloader version
    - fails with 2012.07-00136-g755de79
  - http://marc.info/?l=linux-arm-kernel&m=136432340618226&w=2

* 4430es2panda: MPU, ABE didn't enter target state
  - New for v3.10-rc

* 4460pandaes: pwrdm state mismatch on DSS, ABE, IVAHD, TESLA

* 4460pandaes: chip not entering retention in dynamic idle
  - Presumably 4430es2panda also fails this
  - Suspend-to-RAM enters full chip retention

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 and Santosh Shilimkar report this does not appear with
    the same X-loader/bootloader on his 4430ES2.3 Panda, so could be
    ES-level dependent

am33xx_only and omap2plus_defconfig_2430sdp_only kernel didn't build 
during the v3.9 series.

Good to see that the kernel size has decreased for omap2plus_defconfig.  
Hopefully most of this will remain after ARMv6 support is re-enabled.  
Unfortunately kernel size has increased considerably for 
omap1plus_defconfig.
