-/*
- * pex_config_read - Read from configuration space
- *
- * DESCRIPTION:
- *       This function performs a 32 bit read from PEX configuration space.
- *       It supports both type 0 and type 1 of Configuration Transactions
- *       (local and over bridge). In order to read from local bus segment, use
- *       bus number retrieved from pex_local_bus_num_get(). Other bus numbers
- *       will result configuration transaction of type 1 (over bridge).
- *
- * INPUT:
- *       pex_if   - PEX interface number.
- *       bus      - PEX segment bus number.
- *       dev      - PEX device number.
- *       func     - Function number.
- *       reg_offs - Register offset.
- *
- * OUTPUT:
- *       None.
- *
- * RETURN:
- *       32bit register data, 0xffffffff on error
