I went down the rabbit hole of [datasheets](https://cdn.datasheetspdf.com/pdf-down/U/P/D/UPD720201-Renesas.pdf), [random flash chips](https://github.com/markusj/upd72020x-load/pull/14) and [flashrom](https://github.com/flashrom/flashrom/pull/200) recovery with an not yet supported T25S40.

Any chance you can add support for the predecessor uPD720200 device? Not mine, but there's a uPD720200A (improved power management) too. I get this in dmesg: ``` 558 [ +0.000004]...
