The deleted function in en29f002a.c is reintroduced as
write_by_byte_jedec in jedec.c as it contains no chip-specific
instructions. It is not yet used in other chip drivers, as key addresses
(0x2AAA/0x5555) are often specified with less bits. After crosschecking
datasheets, most of the fixmes can probably be resolved as indicated in
them, causing significant code reduction.
The common JEDEC code for bytewise programming does not program 0xFF
at all. The chips that had a dedicated bytewise flash function which
has been changed to write_jedec_1 thus changed flashing behaviour
and the "write" test flag has been removed. This applies to: AMD
Am29F002BB/Am29F002NBB AMD Am29F002BT/Am29F002NBT (TEST_OK_PREW before)
AMIC A29002B AMIC A29002T (TEST_OK_PREW before) EON EN29F002(A)(N)B EON
EN29F002(A)(N)T (TEST_OK_PREW before) Macronix MX29F001B (TEST_OK_PREW
before) Macronix MX29F001T (TEST_OK_PREW before) Macronix MX29F002B
Macronix MX29F002T (TEST_OK_PREW before) Macronix MX29LV040
Similar analysis should be performed for the read id stuff.

And even when it checks if the erase worked, the result of that check is
often ignored.
Convert all erase functions and actually check return codes
almost everywhere.
Check inside all erase_* routines if erase worked, not outside.
erase_sector_jedec and erase_block_jedec have changed prototypes to
enable erase checking.
Uwe successfully tested LPC on an CK804 box and SPI on some SB600 box.

I sucessfully tested all operations on a Pm29F002T chip. The Pm29F002B is
untested but I assume it should also work.
