I will dropped the "enhanced" word, copied for header
of arch/arm/mach-at91/arm926ejs/eflash.c


/*
  * 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)

....


but not present in commit header

d88bebe16d81 ("AT91SAM9XE: add embedded flash support")


It is more clear
