Simple update file format developed for Somfy, tools and library are
available under LGPLv2 (https://www.gitorious.org/libbpk).
This format in the v1.0 allow you to store 6 types a binary stream for
a unique hardware id:
- bootloader
- bootloader_version
- description.gz
- kernel
- rootfs
- firmware_version
and you can easly add more binary stream type.
The fs will display you in a directory per hw id
and if a binary stream type is unknown will be display
as unknown_%08x
# mount image.bpk /tmp
# ls -l /tmp/hw_id_0/
-rwxrwxrwx 10 firmware_version
-rwxrwxrwx 8 firmware_version.crc
-rwxrwxrwx 1845968 kernel
-rwxrwxrwx 8 kernel.crc
-rwxrwxrwx 5062656 rootfs
-rwxrwxrwx 8 rootfs.crc
-rwxrwxrwx 248 bootloader
-rwxrwxrwx 8 bootloader.crc
-rwxrwxrwx 248925 description.gz
-rwxrwxrwx 8 description.gz.crc
-rwxrwxrwx 4 bootloader_version
-rwxrwxrwx 8 bootloader_version.crc
-rwxrwxrwx 4 unknown_1234567g
-rwxrwxrwx 8 unknown_1234567g.crc
Why BPK and not CPIO or uImage
1) CPIO
cpio does not handle > 4GiB image and does not have any crc checksum
2) uImage
uImage only provide one crc32 for the all data part and only a list of binary
stream with no information about what is what (in multi-image format)
3) BPK
BPK provide a crc32 for the header part and one crc32 per binary stream
so if you does not care of some data you are not force to check them
And you known exactly the binary stream type and for which hw to
use it.

For DDR2 RAMs, regs->zq_config is not used, which causes the
AM33XX_EMIF4_0_REG(SDRAM_CONFIG) register to be left unconfigured, resulting
in boot failure.
It seems that the DDR2 case was missed during the consolidation in commit
9f122f8bf0. The actual call for the Bone was
removed in 88659d9c4a.

The function am33xx_get_cpu_rev may be called before barebox_arm_entry(),
so we need to avoid switch statements. One example is the BeagleBone,
where we use this function to differenciate between the white and black
variants.

This introduces some new environment variable helpers and updates
the existing ones. Newly introduced are:
getenv_bool: read a bool variable
getenv_ul: read an unsigned long variable
getenev_uint: read an unsigned int variable
getenv_nonempty: like normal getenv, but does return NULL instead of an
empty string
All new helpers take a pointer to the value. This value is only modified
when the variable exists. This allows the following programming scheme:
unsigned int myvalue = sanedefault;
getenv_uint("myvalue", &myvalue);
So without checking the return value myvalue contains the best possible
value.
getenv_ull is updated to this scheme.

In theory we can overwrite a builtin command with a script. However,
I don't know a single case where this has been done. Scripts are
often more unflexible than commands so it's unlikely that a script
can extend the functionality of a builtin command. Moreover, the
internal command is no longer accessible once it's overwritten by
a script.
Invert this logic so that a builtin command can overwrite an existing
script. This will help when the 'boot' script is converted to a
builting command. Then with old environments the builtin command will
be used instead of the script.

We used to use struct image_data as the central data structure for bootm and
also as the input data structure. This makes it unclear which of the fields
are actually input data. This patch creates a struct bootm_data which is
exclusively used for input data to make usage clearer.
Also it moves the dispatching of multifile uImage pathnames to the core bootm
code so that the core code gets more flexible and the command code simpler.
