[OpenWrt Wiki] Image Generator
http://wiki.openwrt.org/doc/howto/obtain.firmware.generate

If you do not want to download a prebuild image but you do not want to go through the entire compilation process either, the alternative is to use the Image Generator (former called Image Builder). This is an already precompiled OpenWrt build environment suitable to create custom images without compiling anything.

[OpenWrt Wiki] Using the SDK
http://wiki.openwrt.org/doc/howto/obtain.firmware.sdk

The SDK is a relocatable, precompiled OpenWrt toolchain suitable to cross compile single userspace packages for a specific target without compiling the whole system from scratch.
