[OpenWrt-Devel] [PATCH] image: default block size for squashfs

[Alexey N. Vinogradov]

Sometimes squashfs is necessary for other targets (say, initramfs). In
this case it may not be explicitly checked in the config, and squash fs
block size will not be explicitly defined. This patch will set this
value to 256k in such case.
