M68k/ColdFire: FPU context initialization

[Thomas.Doerfler at embedded-brains.de (Thomas Doerfler)]

Hi,

we are currently adding FPU support for a ColdFire v4e CPU derivate.
After reading, re-reading (and reading again) the relevant files in
cpukit/score/cpu/m68k in the current M68K (with hardware FPU, e.g.
MC68040) CPU Context management, I have not found, where/how the FPU
context is initialized for a newly created thread.

Can somebody please guide me:

- Is the FPU context in an arbitrary state when a new thread is started?

- Or: Where is the code which defines the initial state of the FPU in a
new thred?

Any hint appreciated,

Thomas D?rfler.
