Starting from here...

The text is about MIPS processors.

Atmel is a Sparc processor. Its register set doesn't resemble
the MIPS at all. MIPS was just chosen as an example in the text
above.
If you configure gdb for a generic sparc target, you can get
an idea of the register set gdb will be looking for from a
sparc variant.
