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

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