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.

Linksys WRT300N V1 has pretty bugged CFE bootloader (it crashes in a lot
of situations) that doesn't accept .bin image.

Fix the assembly code to pass the arguments in the correct

Apart from using our new building system there are 2 more changes:
1) Limit amount of images
So far we were generating all standard images (optimized one and two
with no loader) for every SUBTARGET. This is not needed, as e.g. the
only device requiring gzipped kernel is legacy Huawei E970.
2) Change output names
The new image building system requires specifying device name. This
forced picking some and resulted in:
openwrt-brcm47xx-$(SUBTARGET)-squashfs.trx
openwrt-brcm47xx-$(SUBTARGET)-squashfs-gz.trx
openwrt-brcm47xx-$(SUBTARGET)-squashfs-noloader-nodictionary.trx
becoming:
openwrt-brcm47xx-$(SUBTARGET)-standard-squashfs.trx
openwrt-brcm47xx-$(SUBTARGET)-standard-noloader-gz-squashfs.trx
openwrt-brcm47xx-$(SUBTARGET)-standard-noloader-nodictionarylzma-squashfs.trx

compat-wireless/backports now contains a bcm47xx_nvram.h file to
backport some of the functions in it which are used by the bcmfmac
driver. This file just checks for the kernel versions and provide an
empty implementations on older kernel versions. This is OK on most
systems, but on bcm47xx / bcm53xx systems we want to call the real
functions here. This commit removes the file from backports in our
build process like we do it with the bcma and ssb header files. Instead
we add a recent version into our kernel so all code uses only one
header file. On bcm47xx / bcm53xx the real implementations of this code
will be used.

the trx utile uses a maximum image size of 7.2MB. There are brcm47xx
devices even with serial flash with bigger flash chips, but OpenWrt was
not able to create images for these devices. This patch provides an
additional parameter which increases this limit to 32 MB. There is a
warning in the trx utile code which suggests that bigger images could
overwrite the nvram partition on some devices, but normally the program
writing the image should make sure that it is safe to write it to the
flash.

The mips74k subtarget of brcm47xx configures gcc to compile for mips32r2;
however, the generated kernel config for 3.14 and later kernels ends up
with CPU_MIPS32_R1 and CPU_MIPSR1 selected. The generated kernel config
for the 3.10 kernel (Barrier Breaker) properly selected CPU_MIPS32_R2 and
CPU_MIPSR2. Modify the default kernel config for mips74k to explicitly
select CPU_MIPS32_R2 and CPU_MIPSR2.

First of all this patch was affecting other devices, not just Netgear
WNR834B. E.g. Linksys WRT300N v1 also has boardtype 0x0472.
This was breaking PCI on WRT300N, ssb couldn't detect core working in
hostmode (due to mips_busprobe32 failing).
Secondly this patch should not be needed for years now. From the analyze
of #8861 it seems it was needed just to make devices at slots other than
0 discoverable. Setting cardbus to 0 was simply making ssb allow access
to PCI config for devices other than bridge.
With the upstream commit a6c8462 (ssb: fix cardbus slot in hostmode) we
allow accessing device at slot 1 which should be enough for CardBus.
