Subject: mmc: at91_mci: introduce per-mci-revision conditional code
From: Nicolas Ferre <[email protected]>
We used to manage features and differences on a per-cpu basis. As several
cpus share the same mci revision, this patch aggregates cpus that have the
same IP revision in one defined constant. We use the
at91mci_is_mci1rev2xx() funtion name not to mess with newer Atmel sd/mmc
IP called "MCI2". _rev2 naming could have been confusing...
