Blackfin: fix booting with older bootroms (no EVT1)

2009-05-06T12:47:21+00:00

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).

Blackfin: kill off LDR jump block

2009-03-23T19:14:54+00:00

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.

Blackfin: pass RETX to Linux

2009-01-28T18:26:15+00:00

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.

Blackfin: unify cpu and boot modes

2008-03-30T19:50:19+00:00

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).
