* Blackfin: small cpu init optimization while setting interrupt maskMike Frysinger2008-10-23-5/+2
| | | | | | | Use the sti instruction to set the initial interrupt mask rather than banging on the core IMASK MMR to save both space and time. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: set initial stack correctly according to Blackfin ABIMike Frysinger2008-10-23-3/+3

* Blackfin: enable support for nested interruptsMike Frysinger2008-10-23-4/+10
| | | | | | | During cpu init, make sure we initialize the CEC properly so that interrupts can fire and be handled while U-Boot is running. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: unify cpu and boot modesMike Frysinger2008-03-30-0/+219
All of the duplicated code for Blackfin processors and boot modes have been unified. After all, the core is the same for all processors, just the peripheral set differs (which gets handled in the drivers). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
