Hi Mark,
When debugging on register caching, found that register is getting
cached only when write happen to the register otherwise it will not get
cached even any number of read happen.
Is it by intended or there is opportunity to enhance it so that during
read also we can cache it.\?
Thanks,
Laxman

If you check -next you should find that the current code already caches
any single register read.
