Hi Ross,

I was not targeting any specific BSP. I was just using a generic toolchain created with poky. My steps:

1. Clone Poky (or oe-core)
2. Created a generic project and configure for 'qemuarm' (MACHINE=qemuarm changed in local.conf)
3. bitbake meta-toolchain

With this toolchain you can build zImage kernel images but not uImage. Sure the uImage is to be used with u-boot, but I see the value of having a generic ARM toolchain and that still allows me to create uImage files. The mkimage binary adds about 80 KB in a 273 MB toolchain (doesn't seem too much).
