[ECOS] Re: RE : RE : [ECOS] SPI

["Tom Deconinck" <t dot deconinck at gmail dot com>]

You can just use C-code, but if you are using a target that is already
supported there is a big chance there's a cdl package define all
devices for that specific hardware target. For my hardware, I usually
create such a cdl package.

See the the ecoscentric documentation about SPI.
I was just referring to the at91sam7sek target as an example on how to
add the required SPI cdl packages to your target.
