Some CFEs are located at the address currently used for relocation and lzma
loader load address, so we need to provide a way to override it.

There is no need to include the CFE bootloader in the Sercomm factory
images.
There might be a case when this could be useful:
- We are running the stock firmware on the first Sercomm image
- The second partition storing the botloader was erased (unlikely)
Even in this case flashing an image without a bootlader is harmless.
Don't include the bootloader in the factory image creation and rid of the
risk of flashing factory images with an untested bootloader partition.

Some (older) CFEs are loaded at 0x80401000 and ramdisks are loaded at
0x80010000, which means that ramdisk size limit is 0x3F1000 (almost 4M).
Therefore, current ramdisks (~4MB) are overwritting CFE in these devices,
which results in a crash.
This commit changes the address where ramdisks are loaded to 0x80a00000,
which is the same address where kernel is loaded when booting from the flash.
Therefore, lzma-loader will now be loaded at 0x80a00000, but it will still
decompress the kernel at 0x80010000.
Tested with huawei,hg556a-b, which has its CFE loaded at 0x80401000.

Apparently, Sercomm allows loading a BCM WFI image via CFE, but this image
destroys "serial" and "protect" nand partitions, which is wrong.
It will also set both bootflags to the same value, which causes booting
issues with cferam (cferom will alternatively boot from cferam1 or cferam2
each time the device is rebooted).
Now that OEM Sercomm images are supported it's time to remove this hacky
cfe.bin image support.

Introduce support for generating JFFS2 CFE partition tags.
This is used in NAND devices in order to verify the integrity of the JFFS2
partition.

lzma-loader uart output wasn't working on BCM3380/BCM6362 because these
SoCs have the same processor ID.
Let's use CHIP_ID for establishing the UART base address.

Until now only HW modded SPI flash version was supported.
BCM6328 with 64M RAM and 128M NAND.

This change makes the names of Broadcom targets consistent by using
the common notation based on SoC/CPU ID (which is used internally
anyway), bcmXXXX instead of brcmXXXX.
This is even used for target TITLE in make menuconfig already,
only the short target name used brcm so far.
