7dde50d707 mmc: sdhci: Wait for SDHCI_INT_DATA_END when transferring.
sdhci_transfer_data() function transfers the blocks passed up to the
number of blocks defined in mmc_data, but returns immediately once all
the blocks are transferred, even if the loop exit condition is not met
(bit SDHCI_INT_DATA_END set in the STATUS word).

When doing multiple writes to mmc, returning right after the last block
is transferred can cause the write to fail when sending the
MMC_CMD_STOP_TRANSMISSION command right after the
MMC_CMD_WRITE_MULTIPLE_BLOCK command, leaving the mmc driver in an
unconsistent state until reboot. This error was observed in the rpi3
board.

This patch waits for the SDHCI_INT_DATA_END bit to be set even after
sending all the blocks.

Test: Reliably wrote 2GiB of data to mmc in a rpi3.

5a8a8045a9 dm: core: Ensure DMA regions start up with the cache clean
There is a strange interaction with drivers which use DMA if the cache
starts off in a dirty state. Buffer space which the driver reads (but has
not previously written) can contain zero bytes from alloc_priv(). This can
cause corruption of the memory used by DMA for incoming data.

Fix this and add a comment to explain the problem.

This allows the dwc2 driver to work correctly with driver model, for
example.

cdce1f7620 tiny-printf: Add support for %p format
Add support for %p, %pa[p], %pM, %pm and %pI4 formats to tiny-printf.
%pM and %pI4 are widely used by SPL networking stack and is required if
networking support is desired in SPL.
%p, %pa and %pap are mostly used by debug prints and hence supported
only when DEBUG is enabled.

Before this patch:
$ size spl/u-boot-spl
   text	   data	    bss	    dec	    hex	filename
  99325	   4899	 218584	 322808	  4ecf8	spl/u-boot-spl

After this patch (with CONFIG_SPL_NET_SUPPORT):
$ size spl/u-boot-spl
   text	   data	    bss	    dec	    hex	filename
  99666	   4899	 218584	 323149	  4ee4d	spl/u-boot-spl

So, this patch adds ~350 bytes to code size.

If CONFIG_SPL_NET_SUPPORT is not enabled, this adds ~25 bytes.

If CONFIG_USE_TINY_PRINTF is disabled then:
$ size spl/u-boot-spl
  text	   data	    bss	    dec	    hex	filename
 101116	   4899	 218584	 324599	  4f3f7	spl/u-boot-spl

So, there is still ~1.4K space saved even with support for %pM/%pI4.

Compiler used is to build is:
arm-linux-gnueabihf-gcc (Linaro GCC 6.2-2016.11) 6.2.1 20161016

33f0086cb7 env: fix memory leak in fw_env routines
fw_env_open allocates buffers to store the environment, but these
buffers are never freed. This becomes quite nasty using the fw_ tools as
library, because each access to the environment (even just reading a
variable) generates a memory leak equal to the size of the environment.

Fix this renaming fw_env_close() as fw_env_flush(), because the function
really flushes the environment from RAM to storage, and add a
fw_env_close function to free the allocated resources.

00c234f38f env: add a version number to check API
Changes in the environment library are difficult to tracked by programs
using the library. Add simply an API version number that must be
increased each time when the API is changed.

This can be detected and a program can work with different versions of
the library.

9d80b49a67 env: split fw_env.h in public and private parts
Move U-Boot private data into a separate file. This
lets export fw_env.h to be used by external programs
that want to change the environment using the library
built in tools/env.
