Convert the BF537 Stamp board to boot from Serial Nor Flash

The existing parallel flash 4Mbyte size is too small for our application. We need to convert to the larger serial NOR flash. The WIKI "Serial Nor Flash and U-Boot " has some information on the required modifications for the board configuration file and adds a long list of  11 "defines".  Are these simply to be inserted with "#define " in the top of the "STAMP.c" f ile?

#define  CONFIG_BFIN_SPI

#define..............etc.

"

"....

 

Are the following steps correct for the hardware?

1.Switch 16 to position 3

2.Connect the flash chip to the SPI connector

PIN 6 to data on chip

PIN 8 to clock on chip

PIN 10 to select on chip

3.Then use an emulator to store U-Boot in the serial flash.....
