I have largely copied the BF592 EzKit setup with the flash, with one exception.
I have the flash on SPI1 (instead of SPI0) and select is SPI1_SSEL5 on PG11.
There is a lovely example of a flash loader for the EzKit in the examples secion, but I can not see how I am supposed
to change the SPI from 0 to 1.
My actual Flash is a Winbond W25Q16BVSSIG (16Mbit)
whereas the one in the EzKit claims to be a NUMONYX M25P16-VMW6G
They look identical to me in function, so I am guessing it's just the SPI.
