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'.

I'm trying to build L4 Linux with added option of MMC device driver.
When I've tried to compile L4 Linux , I've failed it with error log such
as..
==============
drivers/built-in.o: In function `sdhci_pltfm_clk_get_max_clock':
/home/taeung/test/source/l4linux/drivers/mmc/host/sdhci-pltfm.c:43:
undefined reference to `clk_get_rate'
make[1]: *** [vmlinux] Error 1
make: *** [sub-make] Error 2
==============
After I saw the log , I've guessed the cause is that 'drivers/clk/clk.c'
was not built.
So, I must enable 'CONFIG_COMMON_CLK' , to build 'drivers/clk/clk.c'
How to enable 'CONFIG_COMMON_CLK' ?
You need to add 'select COMMON_CLK' to some platform config block (such
as L4_PLATFORM_GENERIC).
