	* include/flash.h: 
	* src/flash.c: CYGHWR_IO_FLASH_BLOCK_LOCKING is an interface, so
	it's always defined; look for > 0 instead.

2000-08-28  Gary Thomas  <gthomas@redhat.com>

	* src/flash.c: 
	* include/flash.h: 
	* cdl/io_flash.cdl: Support block locking (optional by hardware).

2000-08-22  Hugo Tyson  <hmt@cygnus.co.uk>

	* src/flash.c (flash_program): Add HAL_ICACHE_DISABLE/ENABLE pairs
	around calls to RAM copy of programming/erasing function - this is
	necessary to get reliable operation on EBSA285 and similar.
	Otherwise, what is in the instruction cache might be run instead.

2000-08-14  Gary Thomas  <gthomas@redhat.com>

	* include/flash.h: Add block size mask for finding block boundaries.

	* src/flash.c: Use block size properly.

	* include/flash.h: 
	* src/flash.c (flash_get_block_info): New function.
	(flash_program): Program in block_size chunks as much as possible.
