2008-10-23Blackfin: fix up UART status bit handlingMike Frysinger
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>
2008-10-23Blackfin: small cpu init optimization while setting interrupt maskMike Frysinger
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>
2008-10-23Blackfin: set initial stack correctly according to Blackfin ABIMike Frysinger
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2008-10-23Blackfin: make baud calculation more accurateMike Frysinger
We should use the algorithm in the Linux kernel so that the UART divisor calculation is more accurate. It also fixes problems on some picky UARTs that have sampling anomalies. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2008-10-23Blackfin: decode hwerrcause/excause when crashingMike Frysinger
Having to decode hwerrcause/excause values is a pain, so automate it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2008-10-23Blackfin: fix register dump messagesMike Frysinger
Make sure we report RETI/IPEND correctly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2008-10-23Blackfin: don't bother displaying reboot msg when crashingMike Frysinger
The hang function already tells you to reboot, so no point in showing it twice. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2008-10-23Blackfin: enable support for nested interruptsMike Frysinger
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>
2008-10-23Blackfin: drop unused cache flush codeMike Frysinger
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2008-10-23Blackfin: unify cache handling codeMike Frysinger
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2008-10-23Blackfin: only enable hardware error irq by defaultMike Frysinger
Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2008-05-21Big white-space cleanup.Wolfgang Denk
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>
2008-03-30Blackfin: unify cpu and boot modesMike Frysinger
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>
