/* In order to allow there to be support for both of the processor

classes at the same time, we make a hack here that isn't very

|
pretty. At startup, the link pointed to with the
|
|
branch_irq_lh7a400 symbol is replaced with a NOP when the CPU is
|
|
detected as a lh7a404.

*** FIXME: we should clean this up so that there is only one

implementation for each CPU's design.
