u-boot-flasher fails with current u-boot

u-boot-flasher fails with current u-boot

[Peter.Chubb-RgbkMxAV74wUb6iz2VnApA]

Recent changes to U-Boot have broken u-boot-flasher.    I now see,
after
	./tegra-uboot-flasher flash jetson-tk1
on the serial port:
  >>> Selecting MMC device...
  tegra_mmc_send_cmd_bounced: MMC Timeout
    Interrupt status        0x00000001
    Interrupt status enable 0xffff003b
    Interrupt signal enable 0xffff0002
    Present status          0x01fb02f6
  mmc_init: -1, time 8042

and nothing is flashed to the MMC.

I can do
     ./tegra-uboot-flasher exec jetson-tk1
and everything works as expected.  The running-from-RAM u-boot can
access the MMC.

The patch in U-Boot that causes the problems (found by git-bisect) is
0e513e788f tegra: convert MMC to use driver model for operations

I tried to reproduce this this morning.  Today, even trying to exec
the U-Boot without flashing fails.

So,
	./tegra-uboot-flasher exec  jetson-tk1
with a current u-boot gives an inoperative eMMC.

In the boot header I see:

The good news is I found my Jetson-TK1 and I can repeat your problem.

Why are you running 'mmc rescan'? Is this because the MMC has changed?

This command does not seem to work since it does not re-probe the
driver. It looks like the driver assumes that the controller is reset
each time. I'll send a patch which seems to fix it for me.

Any mmc command fails except 'mmc part' and 'mmc list'.  'mmc rescan'
was just one example that should work.
