to RAM.
 
2000-12-05 Jonathan Larmour <jlarmour@redhat.com>
 
* src/bootblock_flash.c (flash_code_overlaps): Define stext/etext
as array types so no assumptions can be made by the compiler about
location.
 
2000-11-22 Jesper Skov <jskov@redhat.com>
 
* src/bootblock_flash.c (flash_hwr_init): Invalidate icache
instead of disabling it.
 
2000-11-20 Jesper Skov <jskov@redhat.com>
 
* src/flash_query.c (flash_query): A new hardwired flash address.
* src/bootblock_flash.c (flash_hwr_init): Same
 
2000-11-17 Jesper Skov <jskov@redhat.com>
 
* src/flash_erase_block.c: cleanup.
* src/flash_program_buf.c: cleanup.
 
2000-11-16 Jesper Skov <jskov@redhat.com>

* src/flash.h: Same.
 
2000-11-15 Jesper Skov <jskov@redhat.com>
 
* Copy of edb7xxx driver. Need to rewrite to be more generic. Need
CDL options to control number of parts, interleaving, size, etc.
