Heh... yes... this was a commit during development and not planned to be committed as is.
See here (or below) for the "replacement" commit:
https://github.com/hdeller/qemu-hppa/commit/e5271cd0f3b114f4ef518409f1934efd0a77d0cf

Either Richard will include it, or I'll send it for review seperately:

target/hppa: Update to SeaBIOS-hppa from version 10 to 12

SEABIOS_HPPA_VERSION 12 contains those fixes and enhancements:
     - Reduce debug level
     - Update README file for PA-RISC
     - Fix debug name of CPU_HPA_xx if xx >= 10
     - Disable device indexing

SEABIOS_HPPA_VERSION 11 contains those fixes and enhancements
(mostly to enable support for 64-bit Linux kernel):
     - Fixed 64-bit CPU detection via "mfctl,w" instruction
     - Implement PDC_PSW for 64-bit CPUs
     - Added PAT PDC functions:
         - PDC_PAT_CELL
         - PDC_PAT_CHASSIS_LOG
         - PDC_PAT_PD_GET_ADDR_MAP
         - PDC_PAT_CPU
     - Fix return value of PDC_CACHE_RET_SPID space-id bits
     - Introduce new default software IDs for the machines
     - Fix CPU and FPU model numbers
     - Fix 64-bit SMP rendezvous
     - Fix Linux 64-bit kernel crash in STI due to usage of unsigned
       32-bit "next_font" pointer in sti header files
     - Fix graphics output to LASI artist card on PA2.0 machines
     - More USB OHCI endianess fixes
     - Fixes which make ODE run on B160L
     - Fixes which make ODE detect Astro Runway port and CPUs
     - Implement "firmware unlocking" via PDC_MODEL/PDC_MODEL_CAPABILITIES call
     - Add subfunction 2 for PDC_MODEL_VERSIONS
