5. COMPILER
-----------
To create U-Boot the CodeSourcery's version of the GNU Toolchain for the ColdFire architecture
compiler set (freescale-coldfire-4.1-elf) from www.codesourcery.com was used.
You can download it from:http://www.codesourcery.com/gnu_toolchains/coldfire/download.html
compiler that you used - for example, codesourcery_elf requires -MQ in rules.mk, old M68K 2.95.3 just -M
