brcm63xx: work around boot failures with squashfs on BCM6368

Due to the LWL/LWR SMP issue on BCM6368, booting with squash might fail
if the rootfs is not word aligned. As a quick fix, work around it by
ensuring this condition is always true.

brcm63xx: do not align squashfs rootfs start

We do not need to align the start of read only rootfs's to erase blocks.
This allows us to write the squashfs rootfs directly behind the kernel,
potentially freeing up one erase block.

We still need to align for jffs2, so add a flag for imagetag to
optionally align the rootfs start.

bcm63xx: Move the OpenWrt rootfs length field

Dual image capable CFEs store an image sequence at the same place as
currently OpenWrt stores the actual rootfs length, so it will get
overwritten when flashing through such a CFE.

To prevent this from happening, move the rootfs length field to the next
four bytes, thus completely using the reserved1 field.

Since the reserved1 field is now completely in use, it does not make sense
to allow it to be set from the imagetag utility, so remove the option.

Added OpenWRT-specific field to imagetag so that we can record the real root length, so that when the CRC fixup is applied and the root length is recorded as zero we can still calculate the rootfs mtd partition size.

[tools/firmware-utils] imagetag: Significantly updated brcm63xx imagetag writing tool.
* Rewrote commandline parsing code using gengetopt
- We now get long options
- We have more options including use of the info section for
board information (e.g. to add the same boardid but
different GPIOs on different routers)
* Added back the ability to write stock images (this is useful, for example,
when copying the firmware from the in-memory flash, and then being
able to create an image that will let you revert to/test stock firmware
* Fixed copying of CRCs to use memcpy instead of strncpy (strncpy stops at 0)
* Added ability to use all sections of the imagetag, including custom magic
signatures (e.g. for the Telsey router I'm adding soon), info sections,
and reserved sections
* Added putting the router type (as defined in the image generating Makefile)
into the info1 section and the filesystem type in the info2 section.
This will be used by mtd (when I add the code) to return the name of
image used to flash this router. (As requested by Jo, as well as being
useful for same boardid different board scenario described above).

[brcm63xx] flashmap and image generation: reduced union bcm_tag to a single struct
combining the elements so that it is no longer necessary to create an openwrt-only
tagid and tagcrc, and elimate the tagid detection and switch statements which
made dealing with imagetags overly complicated, especially since the logic would
need analogs in all code that touched the imagetag. Patch from cshore.

bcm963xx: add cfe image tagging utility

This replaces the proprietary bcmImageBuilder program from the Broadcom source
drops. It basically adds a 256 bytes header in front of the kernel + rootfs
which contains a few text signatures, the locations of the data as well as the
checksums of the data and the tag. It also adds a 12 bytes header in front of
the LZMA kernel which contains the load address, kernel entry and the size of
the compressed LZMA data.
