We have been using a hack like this;
OpenOCD has a pretty nice table at http://repo.or.cz/openocd.git/blob/HEAD:/src/flash/nor/spi.c#l32
These seem to be the settings needed?
spiflash_read_dummy_bits = 8
spiflash_clock_div = 4
spiflash_total_size = int((16/8)*1024*1024) # 16Mbit
spiflash_page_size = 256
spiflash_sector_size = 0x10000
It would be nice to have a "spi settings" thing for different SPI flash chips following the same vian at https://github.com/m-labs/misoc/blob/master/misoc/cores/sdram_settings.py#L60 for the SDRAM ICs.
