See build/soong/README.md for more information.
As a byproduct, this moves mmc_utils from /system/xbin to /system/bin,
as Soong is not supporting installation into xbin. It also removes the
debug tag, so it's no longer installed by default on all eng and
userdebug builds.

3rd party HMAC SHA256 implementation has been added to the driver,
and since driver common code (mmc_cmds.c) includes calling to
routines and data structures that reside in these 3rd party files
(under 3rdparty\hmac_sha) these files should be compiled as well
in Android.mk makefile.

mmc rpmb write-key <rpmb device> <key file>
Program authentication key which is 32 bytes length and stored in the specified file.
Also you can specify '-' instead of key file path and utility will read the key from stdin.
BEWARE: key can be programmed only once!
Example:
$ echo -n AAAABBBBCCCCDDDDEEEEFFFFGGGGHHHH | mmc rpmb write-key /dev/mmcblk0rpmb -
mmc rpmb read-counter <rpmb device>
Counter value for the <rpmb device> will be read to stdout.
mmc rpmb read-block <rpmb device> <address> <blocks count> <output file> [key file]
Blocks of 256 bytes will be read from <rpmb device> to output file or stdout if '-'
is specified instead of regular path. If key is specified - read data will be verified.
Instead of regular path you can specify '-' and key will be read from stdin.
Example:
$ echo -n AAAABBBBCCCCDDDDEEEEFFFFGGGGHHHH | \
mmc rpmb read-block /dev/mmcblk0rpmb 0x02 2 /tmp/block -
or read the block without verification
$ mmc rpmb read-block /dev/mmcblk0rpmb 0x02 2 /tmp/block
mmc rpmb write-block <rpmb device> <address> <256 byte data file> <key file>
Block of 256 bytes will be written from data file to <rpmb device>.
Also you can specify '-' instead of key file path or data file and utility will read the
data from stdin.
Example:
$ (awk 'BEGIN {while (c++<256) printf "a"}' | echo -n AAAABBBBCCCCDDDDEEEEFFFFGGGGHHHH) | \
mmc rpmb write-block /dev/mmcblk0rpmb 0x02 - -

RPMB requires digital signature of the message. Take the implementation
of HMAC SHA256 from this place https://github.com/ogay/hmac.git
Actually this is BSD license, IANAL but according to my understanding
nothing terrible will happen if we provide all the original copyrights.

Fix the recurisve make targets by using $(MAKE). Otherwise we get lots of
warnings and issues with parallel builds.
Fix the install target -- the man subdir was missing a dummy target.
Add proper .PHONY markings.

Extract a function which sets the OTP PARTITION_SETTING_COMPLETE
bit; once this bit is set there are many other parameters in
EXT_CSD which can no longer be set.
Multiple OTP partition settings can be achieved by calling 'set'
commands with '-n' on all except for the last.

This adds a new option to enable the boot from eMMC
by writing to the 179 ext_csd register.
The example below shows as to enable the mmcblk0boot0
partition and also set/reset the ACK bit).

$ ./mmc extcsd read /dev/mmcblk0boot0 | grep PARTITION_CON

This leaves "extcsd read" pointing to Giuseppe's code. Also, abstract
out the writeprotect code so that there's only one shared implementation
in print_writeprotect_status(), used by both "extcsd read" and
"writeprotect get".

This patch enhances the debug information reported
for the mmc card by parsing the extended CSD registers
obviously according to all the current specifications.
I have no HW to test eMMC 4.5 at this moment. In any case,
the patch supports JEDEC Standard No. 84-B45.
No issues on JESD84-A441 and older specs raised on my side.
This patch indeed want to start providing a full parsing
of the all EXT_CSD registers in the following layout:
Name [FIELD: <value>]
Voluntarily, I added the FIELD because it can actually help on
searching though the SPEC in case of doubts.
In fact, in this stage, not all the register bits are yet parsed.
Currently this has been done for a small subset of registers
(e.g. 173, 160 ...) where IMO it's quite useful for an end-user
to get some details. I do hope this will be improved in the near
feature (also for write operations).
P.S. The original patch posted time ago for the Kernel has been
reviewed-by Sebastian Rasmussen, acked-by: Linus Walleij and reported
by Youssef Tiki.
