2009-05-06Blackfin: fix booting with older bootroms (no EVT1)Mike Frysinger
When dropping jump block support, the assumption was that all bootroms supported entry point redirection via the EVT1 register. Unfortunately, this turned out to be incorrect for the oldest Blackfin parts (BF533-0.2 and older and BF561). No one really noticed earlier because these parts usually are booted by bypassing the bootrom entirely, and older BF533 parts are not supported at all (too many anomalies).

2009-03-23Blackfin: kill off LDR jump blockMike Frysinger
The Boot ROM uses EVT1 as the entry point so set that rather than having to use a tiny jump block in the default EVT1 location. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-01-28Blackfin: pass RETX to LinuxMike Frysinger
Make sure we save the value of RETX at power on and then pass it on to the kernel so that it can nicely debug a "double-fault-caused-a-reset" crash. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

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>
