Cisco ASA itself doesn’t support BGP routing protocol, but it can pass through BGP packets. The dynamic routing protocols supported by Cisco ASA v8.4 are EIGRP, OSPF and RIP.

The ASA does not support BGP. Border Gateway Protocol. BGP performs interdomain routing in TCP/IP networks. BGP is an Exterior Gateway Protocol, which means that it performs routing between multiple autonomous systems or domains and exchanges routing and access information with other BGP systems.
ASA allows passing of BGP sessions through it but just only that. It’s being discussed that it will be supported in the future but there’s no definite date yet.

BGP is supported now on ASA 9.2.1, please see the release notes:
From the link we see:
We now support the Border Gateway Protocol (BGP).
Also, please see the 9.2.1 configuration guide (BGP-section):
Just keep in mind, that just because the ASA supports BGP now, doesn't mean it is a good idea to use BGP on the ASA. From my point of view, keep the firewall and its functions seperate from the routing functions.
