then i add these to Kconfig.debug as it is a common way

        config DEBUG_PRIMA2_UART1
                bool "Kernel low-level debugging on DaVinci DA8XX using UART1"
                depends on ARCH_PRIMA2
                help
                  Say Y here if you want the debug print routines to direct
                  their output to UART1 serial port on SiRFprimaII devices.

        config DEBUG_MARCO_UART1
                bool "Kernel low-level debugging on DaVinci DA8XX using UART2"
                depends on ARCH_MARCO
                help
                  Say Y here if you want the debug print routines to direct
                  their output to UART1 serial port on SiRFmarco devices.

and these in mach-prima2/include/mach/uart.h

  #ifdef CONFIG_DEBUG_PRIMA2_UART1
  #define SIRFSOC_UART1_PA_BASE          0xb0060000
  #elif defined(CONFIG_DEBUG_MARCO_UART1)
  #define SIRFSOC_UART1_PA_BASE          0xcc060000
  #endif

the above codes seem still ugly ?

No, that's fine, about as a good as it gets with today's kernel
capabilities. Just fix the description to have the correct
SoC name instead of "DaVinci DA8XX" ;-)

except the DEBUG_LL uart base address, i missed the zreladdr-y. for
primaii, it is 0x00008000, for marco, it is 0x40008000 as marco's
memory space begins from 0x4000000.
i would to have AUTO_ZRELADDR for the whole SiRF series.
but for uImage load address difference in uImage header, which blocks
multiple SoCs from using same uImage, is "KERNEL_NOLOAD" uImage type
the current generic solution?
