How to enable 'CONFIG_COMMON_CLK' ?

[Taeung]

Thank you very much Adam :-)

I've modified 'l4linux/arch/l4/Kconfig' as follows..
===============

|...(omitted)..

   prompt "Platform support"
   default L4_PLATFORM_GENERIC
   depends on L4_ARCH_ARM

   config L4_PLATFORM_GENERIC
           bool "Generic"
           select CLKDEV_LOOKUP
           select L4_CLK_NOOP
           /("I've//a//dded the content below")/
*           select HAVE_CLK_PREPARE
           select HAVE_MACH_CLKDEV
           select COMMON_CLK*|

|...(omitted)..|

===============

So,I've succeeded in enabling 'CONFIG_COMMON_CLK'.
