//####DESCRIPTIONEND####
//
//==========================================================================

//
// Note: 'bootblocks' are a set of blocks which are treated by
// the driver as a single larger block.  This simplifies the driver
// so as to only have to deal with single size blocks (even though
// the physical device may differ).  The data structure is laid out as:
//    <address of start of boot block area 1>
//    <size of sub-block 1>
//    <size of sub-block 2>
//    ...
//    <size of sub-block n>
//    <address of start of boot block area 2>
//    <size of sub-block 1>
//    <size of sub-block 2>
//    ...
//    <size of sub-block n>
//    _LAST_BOOTBLOCK
//
// Finally, when specifying a device with bootblocks, the total number
// of blocks should reflect this collapse, i.e. if the device has 15
// full size blocks and 8 blocks which are 1/8 each, then the total
// should be 16 blocks.

#define _LAST_BOOTBLOCK (-1)

// Platform code must define the below
// #define CYGNUM_FLASH_INTERLEAVE      : Number of interleaved devices (in parallel)
// #define CYGNUM_FLASH_SERIES          : Number of devices in series
// #define CYGNUM_FLASH_WIDTH           : Width of devices on platform
// #define CYGNUM_FLASH_BASE            : Address of first device
// And select one of the below device variants

#if defined(CYGPKG_DEVS_FLASH_ATMEL_AT49LV040)
//
// Note: this device is not terribly useful for anything other than a bootstrap device
// as it is only 512KB and has only one erase block.
