[PATCH 0/2] mci: fix read timeouts following SD card writes

[Sascha Hauer]

On a KSZ9477-EVB (SAMA5D3), saveenv fails on the first attempt after
the SD card has been freshly flashed, and larger raw writes to the
card fail as well:

  ERROR: atmel_mci f0000000.mmc at f0000000.of: command/data timeout
  ERROR: atmel_mci f0000000.mmc at f0000000.of: command/data timeout

The card is still programming a previous write when the next read
command arrives, and does not answer it. barebox already waits for
the card to become ready before writes, but reads can still hit it
while it is busy.

The first patch makes the atmel_mci timeout message say which command
failed and how, which is what pointed to the cause. The second patch
waits for the card to become ready after each block write.
