By default we are reusing the stack provided by CFE, like it is intended
by CFE. On my WRT54GS it is located at 0x8043BF30, so a big kernel image
could overwrite it. Relocate it to a different memory region which is
still under the 8MB RAM, but in the higher area. We only need this
memory region for the stack of the loader, Linux will set up this
for its own.

The boot process on a WRT54GL works the following way:
1. CFE gets loaded by the boot rom from flash
2. CFE loads the loader from the flash and gzip uncompresses it
3. CFE starts the loader
4. The loader stores the FW arguments and relocates itself to
BZ_TEXT_START (now 0x80600000)
5. The loader reads the Linux image from flash
6. The loader lzma decompresses the Linux image to LOADADDR (0x80001000)
7. The loader executes the uncompress Linux image at LOADADDR
The BZ_TEXT_START was set to 0x80400000 before. When the kernel gets
uncompressed and is bigger than BZ_TEXT_START - LOADADDR it overwrote
the loader which was currently uncompressing it and made the board
crash. Increase the BZ_TEXT_START my 2 MB to have more space for the
kernel. Even on 16MB RAM devices the memory goes till 0x80FFFFFF so this
should not be a problem.

It's a device based on BCM5365P (0x5365 package 0x00). This SoC has
USB 1.1 controller but device has two USB 2.0 parts. They are handled by
PCI-based controllers: 1106:3038 UHCI and 1106:3104 EHCI.

On Asus RT-N12 and RT-N16 models, the WAN and LAN4 ports are swapped in the

Add special casing for these models to detect_by_model() in order to ensure

BCM4704 SoC has only USB 1.1 core:
ssb: Core 3 found: USB 1.1 Hostdev (cc 0x808, rev 0x03, vendor 0x4243)
but this device actually comes with two USB 2.0 ports.
It appears embedded controller isn't used but instead there are two PCI
attached controllers (next to the BCM4321 wireless card):

1106:3104 USB 2.0

WL500GPv1 profile included ath5k which made it usable only for people
who decided to replace default BCM4318 card with Atheros one. We can't
have profile for every possible configuration. If someone adjusts hw in
such a way he can always install a proper package.
WRTSL54GS profile got extra packages for a specific USB usage. Our
standard profile provides basic USB and we should stick to this. We
can't make everyone happy by including packages for all common USB use
cases and all common filesystems.

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.
