Jon,

One question below for others to comment on.

When CONFIG_CYGNUS is set but CONFIG_COMMON_CLK_IPROC is disabled, the
following link failures are caused:

drivers/built-in.o: In function `cygnus_armpll_init':
:(.init.text+0x1d290): undefined reference to `iproc_armpll_setup'
drivers/built-in.o: In function `cygnus_genpll_clk_init':

drivers/built-in.o: In function `cygnus_asiu_init':
:(.init.text+0x1d370): undefined reference to `iproc_asiu_setup'

It is fixed it by always selecting COMMON_CLK_IPROC from
ARCH_BCM_IPROC, and making COMMON_CLK_IPROC a silent option (thus
preventing it from being erroneously disabled by a user).

Should these depends on remain?  I think COMMON_CLK_IPROC won't work
without them.

The ones that were removed were not necessary (as ARCH_BCM_IPROC now
selects it).  I left the "depends on COMMON_CLK" in the off chance
that the dependency chain gets broken some how (as ARCH_BCM_IPROC is
not selecting COMMON_CLK directly, but it is being selected by
ARCH_MULTIPLATFORM).

Thanks,
Jon
