It relates to the SMC which parameter RAM location is in conflict with the SPI/I2C parameter RAM, i. e. SMC1.huh? what does SMC1 relocation have to do with either of I2C or SPI?
Ooops. You are right. Please s/SPI\/I2C/SCC2 ethernet/ ! Before I tell more such nonsense let's quote the description that comes included with the patch: "model allows concurrent operation of Ethernet and SMC(UART) and I2C/SPI by solving the parameter RAM conflict caused by the fact that some of the Ethernet parameters overlay the SMC(UART) and I2C/SPI parameters."
i don't see how SMC1 can be "in conflict with the SPI/I2C parameter RAM" as you claim. can you explain that?
If you use SCC2 for ethernet, it's parameter RAM will use the DPRAM from offset 3E00 to offset 3EA4; without relocation the SMC1 parameter RAM uses offsets 3E80 to 3EB4, thus you have a conflict for the 3E80...3EA4 area.
