Thanks Aneesh.

btw, in case anyone else is interested in making top of tree
u-boot-arm work with beagleboard/-xm, I should mention that it doesn't
work properly with bbtoys-wifi. Also, the default config provided in
the tree still uses ttyS2 whereas the newer omap kernels all use ttyO2
so the serial console goes quiet with top of tree u-boot.

Details:
echo makeubootarm_for_beaglexm ; git clone
git://git.denx.de/u-boot-arm.git u-boot-arm/ ;  make
CROSS_COMPILE=arm-eabi- distclean && make CROSS_COMPILE=arm-eabi-
omap3_beagle_config && make CROSS_COMPILE=arm-eabi-

with Linux 2.6.39 built via OE gives:

If I manually modify bootargs and set console=ttyO2, then boots
normally. But there seems to be a difference between u-boot-arm.git
and OE's u-boot since wifi doesn't work when using u-boot-arm.git.

Taking a quick look at OE's u-boot recipe shows:

Most of these patches seem to already be in u-boot-arm but clearly
something isn't merged yet. I'll try to figure it out if I have some
time. Let me know if this is also a solved issue and I missed
something.

Thanks,
