This commit is the first bad commit in breaking 32-bit boot.

It looks like the jal doesn't jump to the correct address:

0x80000022:  00050433          add             s0,a0,zero
0x80000026:  000584b3          add             s1,a1,zero
0x8000002a:  2c79              jal             ra,670          # 0x800002c8

----------------
IN:
0x800002c8:  00000533          add             a0,zero,zero
0x800002cc:  8082              ret


Oops! Can you point me to the binary to reproduce this?

Cheers,

Bastian
