Dennis,
[quote user="Dennis McLeod"]Where is there a reset for PCIESS ??? I have not found anywhere that says how to bring the entire PCIESS in or out of reset[/quote]
In DM814x datasheet, section 7.3 Reset, we have the following DM814x device reset sources: Power-On Reset, External warm reset, Emulation warm reset, Watchdog reset, Software global cold reset, Software global warm reset and Test Reset.
In subsection 7.3.12 PCIE Reset Isolation we have: All device level resets mentioned in the previous sections, except Test Reset, will also reset the PCIE Subsystem.
You can check also DM814x TRM, section 2.7.13.1 PCIe Reset Isolation
These are the DM814x device level reset signals, controlled through the device PRCM and its registers.
The PCIe module local reset is controlled through the PCIe registers (RSTCMD, PL_LINK_CTRL).

Pavel
