+ * 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 erase command fill the sectors with 0xff
+ *	(if the flashes grow larger in the future and
+ *	someone puts a jffs2 into them)
