Architecture: aarch64
Machine: evbarm
>Description:
I have a Firefly ROC-RK3568-PC running Jared's latest edk2 UEFI firmware v1.3.
The firmware currently is on an SD card (ld1 in the dmesg below).
The machine also has a eMMC which should show up as ld0, but this fails
to power up (sdmmc_enable() returns ETIMEOUT).
Full -current dmesg below.
The failure modes for various NetBSD versions differ:
netbsd-10 and netbsd-11 latest show:
[ 1.778543] sdmmc1: SD card status: 4-bit, C10

However, a "current" kernel from feburary 2024 works:

and I can actually access ld0.
I will enable SDMMC_DEBUG and see what that shows.

There are two separate issues here.
First is solved by a patch suggested by Jared and only affects -current:
Do not clear the SD Bus Power bit for Rockchip "RKCP0D40" sdhc controllers

With this patch my machine reliably detects the eMMC, but only if options
DIAGNOSTIC is defined.
Fix suggested by mlelstv. This also affects netbsd-10 and netbsd-11.
When we see an error from the host controller, delay the soft reset by 100us.

Without this second part I get random failures (differing between cold
boot and also changing after soft reboot). The most populare failures is
"unknown MMC version 6".
With both of thes changes my machine reliably detects the eMMC, with and
without options DIAGNOSTIC.

The patch looks fine, but RK356x doesn't set SDHC_FLAG_ENHANCED, so I'm
struggling to see how this changes anything for you?
When SDHC_FLAG_ENHANCED is NOT set, both with and without this patch, the
delay and sdhc_soft_reset lines will be executed. What am I missing?

Ignore me, I misread the patch. LGTM, ship it!
