01ca7a34f0 brcm63xx/lzma-loader: fix O32 ABI conformance
According to the calling convention of the o32 ABI the caller
function must reserve stack space for $a0-$a3 registers in case
the callee needs to save its arguments.

The assembly code of the loader does not reserve stack space for
these registers thus when the 'loader_main' function needs to save
its arguments, those will be stored in the 'workspace' area instead
of the stack.

Because the workspace area is also used by other part of the code, the
saved register values gets overwritten and this often leads to failed
kernel boots.

Fix the code to reserve stack space for the registers to avoid this
error.

701e2a38fe brcm63xx: add working lzma-loader and use it for initramfs
Add a working lzma loader and use it for generating initramfs kernels
to allow easily netbooting elf kernels on devices with a 4 MiB CFE
size limit.

Based on ar71xx's lzma-loader.

46b4413fbb bcm963xx: fix load address / kernel entry
Current kernels have the same kernel entry as load address, so just set them
like this. Also, the BCM963xx uses 0x80010000 as its load address, so use this
too.

56231056ea strip the kernel version suffix from target directories, except for brcm-2.4 (the -2.4 will be included in the board name here). CONFIG_LINUX_<ver>_<board> becomes CONFIG_TARGET_<board>, same for profiles.
