System: NetBSD gero 8.99.19 NetBSD 8.99.19 (GE) #20: Tue Jun 12 17:27:09 CEST 2018 root@co:/usr/NetBSD/HEAD/src/sys/arch/evbarm/compile/GE evbarm

>Description:
	cvs rdiff -u -r1.24 -r1.25 src/sys/arch/arm/sunxi/sunxi_mmc.c /
	http://mail-index.netbsd.org/source-changes/2018/06/07/msg095817.html
	leads to permanent read / access errors with my BananaPro's sd-card.
	The sd-card still seems to be correctly detected in dmesg though:

>How-To-Repeat:
	Compile an actual SUNXI kernel for evbarm and boot it from (micro) sd-card.
	Accessing the sd-card (ld0) under netbsd (eg. as root partition) fails.
>Fix:
	None provided.
	Reverting sunxi_mmc.c to v1.24 as a workaround makes accessing 'ld0 at sdmmc0' work again.
