Hello,
This patch adds a debugging function dumping the contents of all
registers implicated in the armv7/imx specific sd/mmc controller. It
only prints if the kernel is built with option SDHC_DEBUG and a call is
inserted somewhere.
I am trying to fix the outstanding bug causing the imxesdhc

Hello,
This patch fixes a bug affecting certain 'BeagleBone Black' devices
which prevents the onboard eMMC chip from initializing. It has been
discussed previously but was misattributed to manufacturers bumping its
size from 2GB - 4GB:

Nice work! I wonder why you chose to be so conservative (or arbitrary)
about the after 50 failed attempts condition. :)
My reasoning is that after 50 failed CMD1s, either two things are the
case: The card will only initialize with the sector bit set, or it is
a high capacity device taking a
armv7 kernel will fail to compile with -DSDHC_DEBUG as it lacks a
definition for ommc_dump_regs, so add it.
I previously mailed this patch a while ago[1], but my mail client fudged
tabs/whitespace, here is a working patch.

Hello tech!
A friend is borrowing one of my machines to build the entire pkgsrc
tree, a task that entails compiling more than 15k individual programs.
This has taken 3 days, even on my modern and prepared amd64 machine! (to
my surprise). This has me curious:
