Trouble getting Logic OMAp35x modules to boot
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: Starting kernel ...

That worked a lot better, things came up to the point I was able to SSH into the board and do my testing; I need to fixup my /etc/inittab, etc. to use /dev/ttyOx instead of /dev/ttyOx... However, I'm seeing the same corruption on UART3 at 115200 I mentioned previously in: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg38861.html (and why I'm investigating 2.6.32-rc7). Any ideas why 2.6.37-rc3 exhibits the same behavior? Also, where in the kernel is the mux setup for the UARTs done? I'd like to use UART2 and am not sure how to wire it into the kernel(i.e. setup the mux for it as those pins are in mode 7) and want to follow the same style as that for UART1/3..
