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.
