erasesize

[Frederic Giasson]

	... Maybe it should be passed through the arg pointer in the
ioctl(), in a 2 u_long sized structure?

	I have a question too about the erase->len ( erasesize ).  I have a
flash chip with variable block sizes, and I am using cfi_cmdset_0002.  Where
should that ->len be set?  When I printk the value held by erase->len just
before calling do_erase_oneblock() in cfi_amdstd_erase_varsize(), I get a
dummy value.  I suspect that it should be set according to the
mtd_erase_region_info structure, but it is not done. 

	Does anyone has a clue about it?  

Thanks!

See the other Intel driver. Set the erase size to the 'major' erase size 
for the device, then fill in the appropriate structure to represent the 
other regions.
