Location of EFI Firmware chip on MacBook Air 13" Logicboard?

I have a mid-2011 MBA 13" completely disassembled waiting for a replacement keyboard to arrive (hopefully will be putting together a guide for that). I am wondering if anyone can isolate where the EFI firmware chip resides on the logicboard. I have been looking all around and cannot seem to locate it. My understanding is that it is an Atmel chip (I know that on the newer iMacs and MBPs it is an Atmel AT45DB021D chip).
