* Blackfin: add support for the on-chip MAC status interruptsMichael Hennerich2010-03-091-1/+10
| | | | | | | | | | | | | | | | | | | | | This patch provides infrastructure for MAC Wake-On-Lan and PHYINT use in phylib. New Interrupts added: IRQ_MAC_PHYINT /* PHY_INT Interrupt */ IRQ_MAC_MMCINT /* MMC Counter Interrupt */ IRQ_MAC_RXFSINT /* RX Frame-Status Interrupt */ IRQ_MAC_TXFSINT /* TX Frame-Status Interrupt */ IRQ_MAC_WAKEDET /* Wake-Up Interrupt */ IRQ_MAC_RXDMAERR /* RX DMA Direction Error Interrupt */ IRQ_MAC_TXDMAERR /* TX DMA Direction Error Interrupt */ IRQ_MAC_STMDONE /* Station Mgt. Transfer Done Interrupt */ On BF537/6 the implementation is not straight forward since there are now two chained chained_handlers. A cleaner approach would have been to add latter IRQs to the demux of IRQ_GENERIC_ERROR.

* Blackfin: unify DMA masksMike Frysinger2009-12-151-34/+0

* Blackfin: mass clean up of copyright/licensing infoRobin Getz2009-10-0714-320/+30
| | | | | | | | | | | | | | | | | | Bill Gatliff & David Brownell pointed out we were missing some copyrights, and licensing terms in some of the files in ./arch/blackfin, so this fixes things, and cleans them up. It also removes: - verbose GPL text(refer to the top level ./COPYING file) - file names (you are looking at the file) - bug url (it's in the ./MAINTAINERS file) - "or later" on GPL-2, when we did not have that right It also allows some Blackfin-specific assembly files to be under a BSD like license (for people to use them outside of Linux).

| | | | | | | | | | Many aspects of the Blackfin memory map is exactly the same across all variants. Rather than copy and paste all of these duplicated values in each header, unify all of these into the common Blackfin memory map header file. In the process, push down BF561 SMP specific stuff to the BF561 specific header to keep the noise down. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
