Description
i reported earlier that i'd found hda_sdo on t440p; i did. but i didn't find a test point to connect dvdd from the hda chip to it, not yet anyway
i assumed any +3.3v would be ok, but i've tested it and it doesn't work
so, disassembly on t440p is still needed, for flashing spi1

Research direction
Start with the T440p hardware disassembly described in the issue, focusing on the HDA_SDO signal, the HDA chip's DVDD connection, and SPI1 flashing. Verify whether a suitable test point exists and whether the proposed connection enables flashing; done means a working, reproducible 5-minute flashing method is identified.
