This family of chips was long ago supported by the pre-cfi driver.
CFI code tested on several Zaurus SL-5500 (Collie) 2x16 on 32 bit bus.

Function is_LH28F640BF() mimics is_m29ew() from cmdset_0002.c

[Brian: this patch is semi-urgent, because the following patch switches
  to using CFI detection for a chip which (until now) is unsupported by
  the CFI driver

  9218310  ARM: 8084/1: sa1100: collie: revert back to cfi_probe

The site-specific OOM messages are unnecessary, because they
duplicate the MM subsystem generic OOM message.

None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>.  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

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.

Print out the @adr when the write timeout occurs.
This is useful to check if the write timeouts occur at the
same address.
