Enable build testing and configuration control of the common clk framework so that more code coverage and testing can be done on the common clk framework across various architectures. This also nicely removes the requirement that architectures must select the framework when they don't use it in architecture code. There's one snag with doing this, and that's making sure that randconfig builds don't select this option when some architecture or platform implements 'struct clk' outside of the common clk framework. Introduce a new config option 'HAVE_LEGACY_CLK' to indicate those platforms that haven't migrated to the common clk framework and therefore shouldn't be allowed to select this new config option. Also add a note that we hope one day to remove this config entirely. Based on a patch by Mark Brown <broonie@kernel.org>.

Unicore processors can not fetch/store information which is not
|
|
naturally aligned on the bus, i.e., a 4 byte fetch must start at an
|
|
address divisible by 4. On 32-bit Unicore processors, these non-aligned
|
|
fetch/store instructions will be emulated in software if you say
|
|
here, which has a severe performance impact. This is necessary for
|
|
correct operation of some network protocols. With an IP-only
|
|
configuration it is safe to say N, otherwise say Y.

Always use the default kernel command string, even if the boot
|
|
loader passes other arguments to the kernel.
|
|
This is useful if you cannot or don't want to change the
|
|
command-line options your boot loader passes to the kernel.
|
|
|
|
If unsure, say N.
