I've pulled the latest linux-2.6.37-rc3 kernel from kernel.org, and
using the arch/arm/configs/omap3plus_defconfig as .config, and turning on:
CONFIG_MACH_OMAP35CONFIG_MACH_OMAP3530_LV_SOM=y
CONFIG_MACH_OMAP3_TORPEDO=y
to run on the Logic OMAP35x boards, it failed to boot (no output from
the serial console).
I added:
CONFIG_DEBUG_LL=y
CONFIG_EARLY_PRINTK=y
to turn on early debigging (and adding earlyprintk to the command line),
and see all looks fine up to the end of:

where the output turns to trash on the serial console.
1) Is omap2plus_defconfig the default kernel configuration I should use
for the Logic OMAP35x boards?
2) If so, any suggestions on where/why the console serial port is going
south?
