/*
* this driver supports the enhanced embedded flash in the Atmel
* AT91SAM9XE devices with the following geometry:
*
* AT91SAM9XE128: 1 plane of 8 regions of 32 pages (total 256 pages)
* AT91SAM9XE256: 1 plane of 16 regions of 32 pages (total 512 pages)
* AT91SAM9XE512: 1 plane of 32 regions of 32 pages (total 1024 pages)
* (the exact geometry is read from the flash at runtime, so any
* future devices should already be covered)
*
* Regions can be write/erase protected.
* Whole (!) pages can be individually written with erase on the fly.
* Writing partial pages will corrupt the rest of the page.
*
* The flash is presented to u-boot with each region being a sector,
* having the following effects:
* Each sector can be hardware protected (protect on/off).
* Each page in a sector can be rewritten anytime.
* Since pages are erased when written, the "erase" does nothing.
* The first "CONFIG_EFLASH_PROTSECTORS" cannot be unprotected
* by u-Boot commands.
*
* Note: Redundant environment will not work in this flash since
* it does use partial page writes. Make sure the environent spans
* whole pages!
*/
/*
* optional TODOs (nice to have features):
*
* make the driver coexist with other NOR flash drivers
* (use an index into flash_info[], requires work
* in those other drivers, too)
* Make the erase command fill the sectors with 0xff
* (if the flashes grow larger in the future and
* someone puts a jffs2 into them)
* do a read-modify-write for partially programmed pages
