![]() Add initial configuration parameters for Rasperry Pi 3's sdhost controller, and then configure and use those parameters. This change allows warm reboots of UEFI on Raspberry Pi 3B+ where existing code often fails with "unknown error". See discussion at: https://github.com/pftf/RPi3/issues/24 The basic idea is that some initial configuration parameters (clock rate, bus width) aren't configured into the hardware before commands start being sent. I suspect that the particular setting that matters is the "slow card" bit, but the initial clock setting also seemed wrong to me.
