Can you make sure to include all of the sdio0 pins? I think you're
still missing gpio4d3 (write protect). You're also missing gpio4d5
(bkpwr), not that I know what that actually is.
Also: I know that sdmmc isn't sorted properly (should probably fix
that), but can you sort sdio0 and sdio1 by pin number? So list data
lines first, then cmd, then clock, then detect, then write protect,
...
Same comments apply to sdio1.
