The original implementation assumed that the start/reply doorbells lived within the device _CRS space, but that isn't always the case. On my AMD Ryzen 7640U-based frame.work laptop, device memory runs from 0xc0500000-0xc0500fff while the doorbells are up around 0xc0508000. Stop sanity checking the addresses and just map them in to work reliably whether they're within the device range or not. pluton_wait_reply is cribbed from tpm_wait_for_u32, but rewritten slightly to read in just one place and to read one last time before giving up at the end of the timeout, just in case.

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
