Failure writing to flash in drivers/mtd/chips/cfi_cmdset_0002.c

[Michael Leibow]

I have an AMD Spansion S29GL064M flash chip.  The cfi_amdstd_setup() code in
cfi_cmdset_0002.c chooses a write method:

If( cfi->cfiq->BufWriteTimeoutTyp )
{
   printk( "Using buffer write method\n" );
   mtd->write = cfi_amdstd_write_buffers;
} else {
   printk( "Using word write method\n" );
   mtd->write = cfi_amdstd_write_words;
}

This flash part doesn't seem to work properly with the write_buffers code.
cfi_amdstd_write_buffers() always returns with retlen == 0.

If I comment out the top part of the if and force the "word write" method,
then it works fine.  Anybody else seen this?
