Did you read the previous mail? I explain that.
The LSI focus the latest SoCs. but we got the early chip and used it.
You see the chip itself but I see the product which used the chips
whether for mass production or not.

Actually it's management and maintenance problem. you only show the
latest codes and chips to outside.
but I want to maintain our board at mainline.

Thank you,
