This commit fixes build error:
https://travis-ci.org/hsdenx/u-boot/jobs/123254183
fixed log see:
https://travis-ci.org/hsdenx/u-boot/jobs/123281032
Any ideas why the changes did not work for:
arch/m68k/cpu/mcf523x/start.S
arch/m68k/cpu/mcf52x2/start.S
arch/m68k/cpu/mcf532x/start.S
but work for
arch/m68k/cpu/mcf5445x/start.S
I have no real m68k experiences, so help is appreciated!
sorry, i realized later you was asking the reason why jbsr
is not working with
> arch/m68k/cpu/mcf523x/start.S
> arch/m68k/cpu/mcf52x2/start.S
> arch/m68k/cpu/mcf532x/start.S
jbsr is an alias for bsr.l that is supported only from ISA_B.
In ISA_A it is likely translated to 16bit relative jump.
I prepared some notes, you can check ISA Revisions here:
