ARM i.MX31: add SPI support ...

The i.MX31 SPI interface was refered by freescale as spi_ver_0_4 in one
of their older vendor extended linux releases. spi_ver_0_4 differs only
in minor aspects to spi_ver_0_7 (i.MX35) which is already supported by
barebox.
Regarding barebox, the differences boil down to the location and length
of the CHIP SELECT and BIT COUNT/BURST LENGTH elements of CONREG. The
spi_ver_0_4 variant is limited to single word bursts with a maximum of
32 bits_per_word.

Add support for the i.MX31 SPI interface to the barebox spi_ver_0_7
implementation.

ARM: nitrogen: rename to nitrogen6 ...

Now that the MAX variant of the board is also supported by the
same code, rename the board directory to the more generic nitrogen6.

mc13xxx: make driver-provided SPI frequency overridable ...

The preset SPI frequency for mc13xxx PMIC introduced with patch 6e18b3a48ee4
("mc13xxx: Define maximum SPI clock frequency global to driver") is not
desirable or working on all boards. Provide a possibility to override
the default SPI max_speed_hz from board code.

boot: Print a message when a boot target string does not lead to a boot target ...

When doing a 'boot friesel net' one expects a message when 'friesel'
does not give any bootable results and thus 'net' is booted. This patch
adds this message.

blspec: Turn message back to debug level ...

Normally one should not be interested that the blspec code scans
a directory. In case blspec is not actively used it might even be
confusing, so lower priority of the message in blspec_scan_directory()
to pr_debug.

boot command: Explicitly complain when boot target list is empty ...

When no targets to boot are found it can happen that the boot command
just returns silently. Explicitly print a message in this case to give
a clue what might went wrong.

boot: add single quotes when printing boot target names ...

It's nicer to read when target names have quotes around them, it
makes it clear that this is a string passed in somewhere.

boot: Move code to common/ ...

Normally code in commands/ shall only do the option parsing whereas the
functionality shall be in common/ to make the code usable from C aswell.
Do this in the boot code aswell, move it to common/boot.c and add the
function prototypes to include/boot.h

boot: Use struct bootentries to pass around data ...

We have a struct bootentries type to collect different boot entries,
so use this to pass around data between functions rather than using
an array of strings. With this we also no longer have to convert a
string to a boot entry multiple times.

bootentries: Move struct bootentries to include/boot.h ...

The boot function prototypes are declared in include/blspec.h. Move them

blspec: separate bootentries from blspec entries ...

This completes the separation of the blspec code from the boot
code. With this the boot code only handles generic boot entries
of type struct bootentry which are embedded into the type
(blspec/bootscript) specific structs.

bootentries: Add title/description ...

We currently have to special case blspec entries vs. boot scripts
in the common boot code since we want to print different informations
about them. This adds a 'title' and 'description' which can be filled
in with different information by bootscripts and blspec entries and
so we get rid of the special handling.
