adding board definitions?

2nd post (forum ate the first one)

First of all, excellent work! Installed the Linux version. It was painless and works perfectly!

Second: Question

How do I add a new hardware definition to the board list?
The next run of QuickVGA+ boards includes the SRAM socket as follows:

• Clk=6
• Si=7
• So=8
• Cs=9

I'd like to play with my prototype while I'm waiting for the restock.
How do I add this?

Thanks

I assume that these are SPI SRAM chips? If so, you can use the spi_sram_cache.dat cache driver. Here is are the cache parameters that should work:

    cache-driver: spi_sram_cache.dat
    cache-size: 8K
    cache-param1: 0x07080621 # 0xooiiccpp - oo=mosi ii=miso cc=sck pp=cs-protocol
    cache-param2: 0x09000000 # 0xssxxxxx - ss=cs xxxxxx=unused
