[PATCH] sa1100: collie: fall back to jedec_probe flash detection

[Andrea Adami]

Zaurus 5500 contains 2 LH28F640BFHE-PTTL90 (64M 4Mx16) and
the LH28F640BFHE-PTTL90.pdf datasheet available on the net shows
the exact erasesize and the OTP support.
At the moment only jedec_probe can discover the chip and
the NOR is mounted read only probably because of wrong vpp.

BUMP

At the moment cfi will not detect the collie NOR.
In the meanwhile we can revert to the jedec-probe map which has been
fixed with following commit:

mtd: jedec_probe: fix LH28F640BF definition
fe2f4c8e0bf2756b670ee78fa9772613a2ea8495

Somehow this is unsatisfactory because the flash is mounted READ ONLY
(as from factory, with a RO cramfs).
Further debugging of cfi detection and vpp is needed.
