Title: hi3518ev200: himci MMC probe timeouts add ~55s to boot and
recur every 60s on boards without SD slot
Device
Firmware
Problem
Two MMC hosts are probed although the board wires none. Each probe
times out, and the MMC core keeps polling for card detect afterwards.
Boot timeline from dmesg (printk.time=1):
That is roughly 55 seconds of pure MMC timeouts before the rootfs
mounts. Without them the kernel would reach userspace in under 10s.
It does not stop after boot. Bursts recur at 67.8s, 128.4s, 178.5s —
a full cycle every 60 seconds, indefinitely. On a 269 BogoMIPS ARM926
this is a permanent tax.
U-Boot already detects the absence correctly:
"No EMMC/MMC/SD device found !"
Suggested fix
Set the mmc nodes to status = "disabled" in the device tree for this
SoC, or drop CONFIG_HIMCI from the kernel config. U-Boot configs for
other families already ship with "# CONFIG_HIMCI is not set".
Happy to test a patch on this board if needed...
