This config exists entirely to hide the cpufreq menu from the kernel configuration unless a platform has selected it. Nothing is actually built if this config is 'Y' and it just leads to more patches that add a select under a platform Kconfig so that some other CPUfreq option can be chosen. Let's remove the option so that we can always enable CPUfreq drivers on unicore32 platforms.

Find out whether you have a PCI motherboard. PCI is the name of a
|
|
bus system, i.e. the way the CPU talks to the other stuff inside
|
|
your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
|
|
VESA. If you have PCI, say Y, otherwise N.

help

|
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.
