This file contains most recent instructions about 
building current version of FreeBSD for microblaze target

To begin a proper toolchain will be needed. Currently the easiest way to obtain 
a toolchain is using a bash script './microblaze-gcc/build-toolchain.sh'.

You can then put created install dir whatever you want it. 
Next edit './src.conf' file and change 'MB-TOOLCHAIN' value to the path where 
toolchain has been moved (remember about 'bin' subdirectory).

After that type 'make kernel-toolchain' and wait to complete. This step currently 
does not build microblaze toolchain, but will make some necessary tools for next 
steps (config, etc.).

Now it's time to set env value 'TARGET_ARCH' to 'microblaze'. 

You can change the MAKEOBJDIRPREFIX env if you do not want to use default directory
(/usr/obj/microblaze.microblaze).

And finally this can be executed:
`make SRCCONF=${PWD}/src.conf buildkernel`
