Use the existing system reference instead of Core::System::GetInstance(),
and calculate the phase 2 scheduling delay from GetTicksPerSecond()
instead of hardcoding 50000 ticks.
The legacy Execute1 path (offset=0, length=0) was using Write_U32
(big-endian) to write the "TEST OK" status string. However, the PPC
display code in segaboot reads this buffer with lwz followed by manual
bswap32, so the data must be stored in little-endian. Use Write_U32_Swap
to match the other two TestHardware paths.
Implement the MediaBoard commands and response protocol needed for
the segaboot NETWORK TEST to pass:
- TestHardware (0x0301) two-phase response via CoreTiming: phase 1
echoes test_type with 0x80 acknowledgment flag, phase 2 sends
result with testStatus=2 and checkProgress=100
- GetNetworkConfig (0x0104) with trinetcfg.bin read intercept
- Separate Execute1/Execute2 last-response buffers to prevent
cross-clobber on the shared s_media_buffer
- Generic 0x80xx cleanup command acknowledgment
- Network config persistence for SET IP ADDRESS
