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.
