I had to tweak the if (writecnt> 5) {} clause to allow for the
larger size but other than that this Works For Me. It drops the
program time on my 128k part to 30 seconds. Thats quite a bit better
than the 20 minutes it used to take.
I also verified that chunk sizes larger than 12 fail but I didn't try
any values between 1 and 12.
Thanks for testing! New patch follows. If I get an ack, I'll commit.
Add chunked write ability to the Dediprog SF100 driver.
Please note that the write speedup only applies to chips which have SPI
page write (i.e. chips using spi_chip_write_256).
This is a quick fix for write speed until I get around to implementing
full bulk SPI write support.
Tests appreciated.
