/ebsa285/v2_0/ChangeLog
0,0 → 1,80
2001-09-28 Jonathan Larmour <jlarmour@redhat.com>
 
* src/ebsa285_flash.c (flash_hwr_init): Only re-enable icache if it
was enabled before.
 
2001-07-11 Andrew Lunn <andrew.lunn@ascom.ch>
 
* src/flash.h:
* src/ebsa285_flash.c (flash_hwr_init): Support new device 28F008SC.
 
2001-06-11 Gary Thomas <gthomas@redhat.com>
 
* src/ebsa285_flash.c: Remove dependency on printf() via user functions.
 
2001-05-23 Jesper Skov <jskov@redhat.com>
 
* cdl/flash_ebsa285.cdl: Needs IO controller to copy functions to
RAM.
 
2000-12-05 Jonathan Larmour <jlarmour@redhat.com>
 
* src/ebsa285_flash.c (flash_code_overlaps): Define stext/etext
as array types so no assumptions can be made by the compiler about
location.
 
2000-08-29 Gary Thomas <gthomas@redhat.com>
 
* src/ebsa285_flash.c: Improve error decoding.
 
2000-08-22 Hugo Tyson <hmt@cygnus.co.uk>
 
* src/ebsa285_flash.c (flash_hwr_init): Add
HAL_ICACHE_DISABLE/ENABLE pairs around calls to RAM copy of query
function - this is necessary to get reliable operation on EBSA285
and similar. Otherwise, what is in the instruction cache might be
run instead.
 
2000-08-15 Gary Thomas <gthomas@redhat.com>
 
* src/ebsa285_flash.c (flash_code_overlaps):
stext,etext now are _stext,_etext
 
2000-08-14 Gary Thomas <gthomas@redhat.com>
 
* src/ebsa285_flash.c: New file(s).

2002-03-06 Nick Garnett <nickg@redhat.com>
 
* cdl/flash_integrator.cdl: Converted to use generic 28Fxxx flash
driver.
 
* src/arm_integrator_flash.c:
This file added to parameterize generic FLASH driver. Also define
here CYGHWR_FLASH_WRITE_ENABLE() and CYGHWR_FLASH_WRITE_DISABLE()
to turn FLASH writing on and off.
 
* src/flash.h:
* src/flash_erase_block.c:
* src/flash_program_buf.c:
* src/flash_query.c:
Files removed. These are the old flash driver.
2001-10-30 Philippe Robin <Philippe.Robin@arm.com>
2001-10-30 Jonathan Larmour <jlarmour@redhat.com>
 
* Initial version of ARM Integrator flash driver.
