"iicbus0: <unknown card> at addr 0x77" nice!
Would be great if you could run `i2c -s` also.

Posted the i2c patch: https://reviews.freebsd.org/D24917

Oh well, at least we know the GIC patch is innocent.

And at least it's just SATA, no complaints from USB or PCIe.

Speaking of, looking forward to your testing of PCIe cards ;)

> sdhci_acpi0-slot0 seems to have hung the boot process for almost 5min waiting for various timeouts.

oops, so they didn't really make generic sdhci work :D

Well turns out we do have a Freescale ESDHC driver already.
It doesn't have DMA so performance won't be great (but SD/MMC is bad stuff anyway lol).
(interesting dev note: NetBSD gets away with just some quirks in the sdhci acpi driver:
SDHC_FLAG_HAVE_DVS|SDHC_FLAG_NO_PWR0|SDHC_FLAG_32BIT_ACCESS|SDHC_FLAG_ENHANCED)

Trying to add ACPI support to it:
