Subject: Re: [PATCH] Remove support for score architecture

Before we start the development of the S+core, Sunplus had licensed
ARM and MIPS. We develop S+core for other reason such as the price.
Some products on the web of Sunplus adopt S+core , for example
the SPV7050.(http://w3.sunplus.com/products/spv7050.asp) These products
could still be bought from the market. Some high-end products adopt
ARM or MIPS. So, there is no conflict for a company adopts multiple
architectures.

As I said, we recognize that we rarely update because of the limited
applications and rare requests from customers. Maybe we don’t
understand the culture enough; we think that it is unnecessary if we
have no new bugs or new functions, the thought seems wrong. We can
commit some patches in the near future.

Best,
Lennox
