* Blackfin: use new bfin read/write mmr helper funcsMike Frysinger2010-01-17-12/+14

* Blackfin: audit UART for all known anomaliesMike Frysinger2009-04-06-1/+20
| | | | | | | There is no code change here, just new comments, but this keeps me from having to do another audit from scratch in the future. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: allow serial console to be disabledMike Frysinger2009-01-28-0/+4
| | | | | | | Some devices have no UART device pulled out, so allow people to disable the driver completely in favor of other methods (like JTAG-console). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: fix up UART status bit handlingMike Frysinger2008-10-23-12/+60
| | | | | | | | Some Blackfin UARTs are read-to-clear while others are write-to-clear. This can cause problems when we poll the LSR and then later try and handle any errors detected. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Big white-space cleanup.Wolfgang Denk2008-05-21-1/+1
| | | | | | | | | | | This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>
* Blackfin: unify cpu and boot modesMike Frysinger2008-03-30-0/+124
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>
