I'm going to be writing a driver for the SSI2 interface on my EDB7111-2
board. Would it be safe to assume that the layout for the RS232 serial
driver would be a good start? If so, does anyone know off hand if all
the EBD7XXX boards have the same SSI2 interface? I think most of those
boards have the same CPUs right - EP7211? If so, then they must all
have the same SSI interface because I think it's internal to the CPU.
I would also like to know where I should put this driver!
devs\serial\arm\edb7xxx\ already has a current directory. Is it ok to
put another directory called "ssi2" under there? If so, maybe current
should be put into a directory called rs232 or serial or something?
Before I start, is anyone out there that's already done this and is
planning on contributing it to the eCos repository?
