Since this is more a user-forum I would suggest you to create a technical case with your demands. To do so, at top of this page go to
Support -> Technical Support -> Create a Case
May take some time, but one of the Cypress engineers will care for that.
Are you looking for an USB 2.0 product or USB 3.0 product?
If you are looking for USB 2.0 then please refer to the following webpage to get more details.
If you are looking for USB 3.0 then please refer to the following webpage to get more details.
These 2 chips have the support for latest SD 3.0 (SDXC with UHS-I) and eMMC 4.41 standards.
thanks for your suggestion .

Please find the answers to your questions below:
1). Processor port can directly access that storage connected to Westbridge chip. Cypress will provide the block drivers that are need to be integrated on the processor connected to Pport.
2)We have two different variants in Westbridge product family.
Products start with A (Antioch, Astoria, Arroyo) - supports only SD2.0 cards.
Products start with B (Bay, Benicia) - supports SD3.0 cards (larger than 32GB). i think you may need to go for Bay or Benicia.
3). Yes. It is possible.
4) You can contact your local sales or you can create a tech support requesting for a DVK.
5) We have an example when two SD cards are connected to the 2 storage ports of Bay or Benicia.
