swr/swl instructions used for word aligning were wrong. This
made memset() terribly broken. I can't imagine how it went
uncaught for soooo long. Spotted by Solomon Peachy.
I run unit tests for alignments 0,1,2,3
size 1, 2, 3, 4, 5, 63, 64, 65, 127, 128, 129;
and fill pattern 0x00 and other (since 0 is special case in this
implementation).

Previously only atomic read/write 8/16/32 were exposed. But it is useful to
be able to read a whole buffer at once, this is more efficient than N times
read8.

The encryption definitely uses some standard elliptic curve encryption over
binary fields (163 and 233 bits, standard polynomials). It is still unclear
how this is used in the actual encryption, the key authentification and
derivation do not look standard.

Now print list of devices immediately even if the rest of the command line
is empty (ie 'scsitool -s ?' works, whereas before one would need an actual
device to even get a list). Add more information in the help_us command:
print kas, lyr and fpi.

The tool now provides more useful information for developers when the device
is not supported. Is also has a new verb "help_us" that also prints all this
information (notably the device info and model ID).
Change-Id: I04baec8fff23eb83a0408add6296b5d42e9aa8e7
We still miss the model IDS for those device so scsitool won't be able to
recognize them automatically.

DES ignores the parity bit of each byte (making the 64-bit key really 56-bit),
but the current code skipped the parity bit of each half-byte, thus missing
some keys.

Strangely it has the SAME encryption key as the E450. Either they didn't bother
changing it or more likely they have exactly the same internals and a slightly
different case.

SUPPORTED SERIES:
- NWZ-E450
- NWZ-E460
- NWZ-E470
- NWZ-E580
- NWZ-A10
NOTES:
- bootloader makefile convert an extra font to be installed alongside the bootloader
since sysfont is way too small
- the toolsicon bitmap comes from the Oxygen iconset
- touchscreen driver is untested
TODO:
- implement audio routing driver (pcm is handled by pcm-alsa)
- fix playback: it crashes on illegal instruction in DEBUG builds
- find out why the browser starts at / instead of /contents
- implement radio support
- implement return to OF for usb handling
- calibrate battery curve (NB: of can report a battery level on a 0-5 scale but
probabl don't want to use that ?)
- implement simulator build (we need a nice image of the player)
- figure out if we can detect jack removal
POTENTIAL TODOS:
- try to build a usb serial gadget and gdbserver

Several people asked me recently how to decrypt atj2127 firmware. Someone
posted on github (https://github.com/nfd/atj2127decrypt) a decrypt utility
clearly reverse engineered from some unknown source. The code is an absolute
horror but I concluded that ATJ changed very little between ATJ213x and ATJ2127
so I added support for the ATJ2127, credit to this github code that I stole
and rewrite (code was under MIT licence). At the same time do some small code
cleanups.
Note that there is not 100% sure way that I know to distinguish between the
two firmware types, so the code tries to do an educated guess to detect
ATJ2127. If this does not work, use --atj21217 option. Also note that contrary
to the github tool that decrypts and unpack in one go, this tool only does one
step at once. So first decrypt: HEX -> AFI, then unpack AFI -> files.
I also added for a different version of AFI. Based on AFI files I have, there
are, I think, two versions: the "old" ones (pre-ATJ213x) and "new" ones. The
tool only supported the new one but for some reason the ATJ2127 uses the old
ones without a mostly empty header. Strangely, even this mostly empty header
does not seem to follow the old layout as reverse engineered by the s1mp3
project (https://sourceforge.net/p/s1mp3/code/HEAD/tree/trunk/s1fwx/heads.h),
so in fact there might be three versions. In any case, only the header is
different, the rest of the file is identical so at the moment I just don't
print any header info for "old" files.

The devinfo request returned the raw data, now the tool prints the various
fields. Also add support for the dhp (destination/headphones/color ...): this
one is untested because it's only supported starting from A10 or A20. There is
still a problem with the dpcc prop: although it should work for DEVINFO, it does
not, despite the fact that the get_dev_info command works and is internally (on
the Sony) translated into a dpcc request. I keep the code just in case.

The detailled error message is only printed if -d switch is on command line,
otherwise there is no error message which is wrong so fix that.

I am unsure about the names of the player, the manual says A36HN and A37HN but
at the same time there is a A35 and A35HN with the same ID, and Sony does not
usually put the "HN" in its device list.

* make gen_db.py work on Windows/Python 2
- use hashlib module instead of md5sum, also don't rely on / for file path
matching
- don't use 'file' for a variable name
* fix parse_nvp_header.sh for older kernels
pre-emmc kernel sources use a slightly different #define format; adjust
regexp to catch it.
* add nwz-x1000 series NVP layout (from icx1087_nvp.h)
some new tags have no description, alas the driver doesn't have
them :/
* minor fixes to nvp/README
fixed typos/wording
Change-Id: I77d8c2704be2f2316e32aadcfd362df7102360d4
* added KAS for nwz-x1000 (extracted from an NWZ-X1060 via "get_dnk_nvp kas")
* hint that -o is needed when extracting

The code dependend on the sg_lib header being present, remove this dependency
so that we only need public headers.

...by QStyleOptionViewItem. Yes Qt got it right, in 5.7 they deprecated
QStyleOptionViewItemV4 and recommend using QStyleOptionViewItem which contains
less fields except on newer Qt where it contains all fields. Hopefully it still
works on Qt>4.x for a large enough value of x.

The clock structure is identical, and the EMI are the same.
Also fix SSP clock, it was broken on imx233 as well.
