	* include/devtab.h: 
	* src/iosys.c:

	cause to add placeholders for future developments.

	entries in the cyg_devio_table_t structure and adding a char/block
	discriminator flags to the devtab entry status field. API calls
	cyg_io_bwrite() and cyg_io_bread() have also been added.

	needs to be changed to accomodate this addition.
