Title:
MIPS Malta mini-bootloader print function has bad jump instruction
Status in QEMU:
Fix Released
Bug description:
One of the hardcoded bootloader library instructions in the MIPS Malta
mini-bootloader's print function is:
stl_raw(p++, 0x08000205); /* j 814
*/
Since this function is loaded at 0xbfc00808, this jump jumps to the
middle of nowhere. The properly-encoded instruction is:
stl_raw(p++, 0x0bf00205); /* j 814
*/
With this patch, the print function behaves as expected.
