Hi,

collie seems to contain LH28F640BF flash chips. According to 
http://sharp-world.com/products/device/flash/pdf/*FUM00701*@E.pdf
(page 83) if they have 0x51 of Extended Query Table (number of hardware 
partitions) set to zero, they have a single fixed partition.
This patch makes those chips work.

Regards,
Thomas
