* 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.
