PCI trace buffer
CONFIG_PCI_TRACE
  The PCI trace buffer implements a simple on-chip logic analyzer
  to trace the PCI signals. The PCI AD bus and most control signals
  are stored in a circular buffer, and can be read out by the DSU
  or any other AHB master. See the manual for detailed operation.
  Only available for target technologies with dual-port rams.

PCI trace buffer depth
CONFIG_PCI_TRACE256
  Select the number of entries in the PCI trace buffer. Each entry
  will use 6 bytes of on-chip (block) ram.
