Re: introduce SH 2a simulator

[Andrew Cagney <cagney at gnu dot org>]

Can you revise the ChangeLogs as follows:

> 	* sim-sh.h: Add new sh2a banked registers.

Write this as

YYYY-MM-DD  Michael Snyder ....

	Committed by ....
	* change.

Rewrite the below as:

YYYY-MM-DD  Michael Snyder ....

	Committed by ...
	* final set of changes

instead of a long winded change history.

and repost.
