Please describe what it actually means. Enhanced in what way?
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

Simon
Thanks
