- * 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 environment 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
