02778f2f1b Blackfin: fix booting with older bootroms (no EVT1)
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).

7e1d212b6d Blackfin: kill off LDR jump block
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.

b1e9435b64 Blackfin: pass RETX to Linux
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.

9171fc8172 Blackfin: unify cpu and boot modes
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).
