Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

	  The QUICC Engine (QE) is a new generation of communications
	  coprocessors on Freescale embedded CPUs (akin to CPM in older chips).
	  Selecting this option means that you wish to build a kernel
	  for a machine with a QE coprocessor.

config UCC_SLOW
	bool
	default y if SERIAL_QE || (CPM_QMC && QUICC_ENGINE)
	help
	  This option provides qe_lib support to UCC slow
	  protocols: UART, BISYNC, QMC

config UCC_FAST
	bool
	default y if UCC_GETH || QE_TDM
	help
	  This option provides qe_lib support to UCC fast
	  protocols: HDLC, Ethernet, ATM, transparent
