There was a problem hiding this comment.
presumably pointer provenance would eventually prefer us to use ptr::from_exposed_addr for ... all of these shenanigans, but that's not real yet...

This is an exercise fixture for the PSRAM mode of the Flexible Memory Controller on the STM32H7, for evaluating FPGA interface options. It lets you do many ill-advised things via IPC. They all appear to work, no matter what the datasheet implies. Good luck!
