The biggest (and the only?) disadventage of this is obviously an
increased image size.
For mips74k the size of vmlinux goes up from 4186684 B to 4701436 B.
Most devices use LZMA compressed kernel so probably more important is
vmlinux.lzma size which goes up from 1342945 B to the 1508498 B.
Still this isn't something that should stop target kernel bump. There
are various adventages of kernel 4.14. If kernel / image size is a
serious concern for anyone, it's perfectly possible to use previous
release which is pretty solid for the brcm47xx.

Kernel 4.9 is now working on the brcm47xx boards, we just recently fixed
the problem that some boards did not boot at all, by changing the memory
regions used to relocate the kernel to in the loader.

Kernel 4.4 was ready for brcm47xx for almost a year now but I kept
postponing the bump due to problems with Linksys WRT300N v1.0. OpenWrt
and LEDE with 4.4 were hanging at the booting with the:
> Starting program at 0x80001000
(the last CFE message).
This was a permanent state, "make distclean" wasn't helping, I spent
hours debugging this and I was reliably reproducing the issue every
time. I also reported it on linux-mips ML in the thread:
> BCM4704 stopped booting with 4.4 (due to vmlinux size?)
After ~month I started working on WRT300N again. I got hangs as expected
every time I switched from 4.1 to 4.4. I started experimenting with:
1) TRX content (I tried dropping rootfs partition)
2) BZ_TEXT_START of lzma-loader
3) Flashing other variants of image: lzma compressed kernel (without a
loader), gzip compressed one, uncompressed one.
At some point I got rootfs-less image booting and after that I couldn't
reproduce problem anymore, even with a complete firmware. It seems like
hardware was in some locked/unstable state that got magically fixed.
I have LEDE working now, tested it even with "make distclean", it seems
we can bump kernel now. I'll keep testing it on WRT300N for some time.

replace all occurences of LINUX_VERSION with the cleaner
approach. future kernel upgrades must mostly touch only
one file. the only platform left is netlogic, because it
uses a intermediate kernel 3.14.16

With this patch the mips74k subtarget will be compiled with optimized
compiler options to generated smaller and faster code. This currently
breaks broadcom-wl, because the binary blob is only compiled with
mipsr1 support.

All new devices (with MIPS 74K CPU) are based on BCMA SoC and have
Ethernet core supported by bgmac. Create a new subtarget to generate
optimized builds.
This is just a beginning, further tweaks (like kernel configuration)
are still possible. This decreases default root.squashfs by ~128 kB.

This makes it possible to use swconfig to controll the switch.
This was tested with devices using b43 and bgmac.
This was not tested on devices using tg3.
This does not support the adm switch used in some very old devices.
