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

145 Always use the default kernel command string, even if the boot
146 loader passes other arguments to the kernel.
147 This is useful if you cannot or don't want to change the
148 command-line options your boot loader passes to the kernel.
