Hi,

The omap1's debug-macro.S is similar to the generic 8250 code. Compared to the 8520 code the omap1 macro automatically determines what UART to use based on breadcrumbs left by the bootloader and automatically copes with the eccentric register layout on OMAP7XX.

• config DEBUG_OMAP1UART1

• bool "Kernel low-level debugging via OMAP1 UART1"
  

• depends on ARCH_OMAP1 && !ARCH_OMAP730
  

Did you try this with omap1_defconfig and then running menuconfig to see how it looks like? The patch allows to select only OMAP730 ports, but the kernel should be bootable on all core types...
