Missing register Zynq UltraScale+ Devices Register Reference

0xFF5E0250, mentioned and used in FSBL PMUFW and ATF as PSU_CRL_APB_BOOT_PIN_CTRL (or the like) and used to control the USB ULPI reset pin on Xilinx demo boards is nowhere to be found at https://www.xilinx.com/html_docs/registers/ug1087/ug1087-zynq-ultrascale-registers.html

One can sort of make out the register layout from the defines in FSBL/PMUFW/ATF, but it should really be part of the official reference site.

As you have deducted, this register controls how the boot mode pins behave after boot. Like any GPIO

Hi @ibaie ,

I haven't been able to find register 0XFF5E0250 in the register map even now, 8 months after your reply. I have met some more accesses to registers that are not included in the register map. Can you tell me whther it is a bug or Xilinx is intentionally hiding registers? Even description of registers included in the map is not always clear or sufficient. Can we hope in any update of the map?

Thanks

Marek
