Each different OpenWrt platform represents a family of SoCs from the software point of view. This means, we can use the same compiler options and the same drivers to get them working with OpenWrt. The different functionalities can be contained on single chip or on multiple chips soldered to a circuit board.
The most crucial component of any SoC is the CPU. The company that designs the SoC, purchases the specifications for a certain CPU model from a company that designs CPUs, e.g. MIPS Technologies or ARM Holdings either as Soft-IP or as SIP.
One or multiple CPUs are combined with other components, such as
- other PUs (for VoIP, etc) →Digital signal processor
- you name it
The actual production of the chip is then executed by a semiconductor foundry.
Most SoC manufacturers license a (soft or hard) IP core for a certain CPU design from a licensor like MIPS or ARM, then combine this with other (self-developed or licensed) (soft or hard) IP cores for DSP-, wireless-, VoIP-, Sound-, Switch-, etc-functionality and commission the manufacturing of Chips at some semiconductor foundry. These Chips, SoCs, are acquired by different manufacturers of Routers. The latter design PCBs for whatever purpose and solder the purchased chips (SoC, RAM, Flash) onto them.

For a List of Devices and Manufacturers, simply have look at the Table of Hardware.
Boards based on the old Atheros AR231x/AR5312 CPUs. The AR531x/231x is a platform by Atheros, which is used for dual-band and single-band 108Mb/s routers and APs. It is also referred as a WiSoC - Wireless System-on-a-Chip, and the radio inside often refereed as RoC - Radio-on-a-Chip as it is contained on a distinct chip.

Boards based on current Atheros AR71xx/AR7240/AR913x CPUs.
1. Atheros AR9100 routers As of January 2009, active work is under way to get OpenWrt running well on these routers. AR9132 400Mhz MIPS CPU seems to be on all models, Das U-Boot is the most frequent bootloader, all seem to have 32MB of RAM and at least 4MB of FLASH. The CPU is typically paired with the AR9102 (2x2 MIMO), or AR9103 (3x3 MIMO) radio chip. Check the Kamikaze forums for latest information.
