This is only true for some definitions of ARM. See for example:
https://en.wikipedia.org/wiki/Amber_(processor)
"The Amber core is fully compatible with the ARMv2a instruction set and is thus supported by the GNU toolchain. This older version of the ARM instruction set is supported because it is not covered by patents, and so can be implemented with no license from ARM Holdings"
