- * orion5x_config_adr_windows - Configure address Windows
- *
- * There are 8 address windows supported by Orion5x Soc to addess different
- * devices. Each window can be configured for size, BAR and remap addr
- * Below configuration is standard for most of the cases
- *
- * If remap function not used, remap_lo must be set as base
- *
- * NOTES:
- *
- * 1) in order to avoid windows with inconsistent control and base values
- *    (which could prevent access to BOOTCS and hence execution from FLASH)
- *    always disable window before writing the base value then reenable it
- *    by writing the control value.
- *
- * 2) in order to avoid losing access to BOOTCS when disabling window 7,
- *    first configure window 6 for BOOTCS, then configure window 7 for BOOTCS,
- *    then configure windows 6 for its own target.
- *
- * Reference Documentation:
- * Mbus-L to Mbus Bridge Registers Configuration.
- * (Sec 25.1 and 25.3 of Datasheet)
