This patch significantly improves the reliability of high speed
usb writes on the bcm5354. It implements a work around for version 2
of the usb20 core that was cribbed from the GPL sources for the
Asus wl500gpv2 and verified against the wl520gu sources.
Reference:
GPL/WL-520gu-NewUI/src/linux/linux/arch/mips/brcm-boards/bcm947xx/pcibios.c

The GPIO API is supposed to return 0 or a negative error code,
but the SSB GPIO functions return the bitmask of the GPIO register.
Fix this by ignoring the bitmask and always returning 0. The SSB GPIO functions can't fail.

This add watchdog driver for broadcom 47xx device.
It uses the ssb subsytem to access embeded watchdog device.
Because the watchdog timeout is very short (about 2s), a soft timer is used
to increase the watchdog period.
Note : A patch for exporting the ssb_watchdog_timer_set will
be submitted on next linux-mips merge. Without this patch it can't
be build as a module.

the current ssb irq setup (in ssb_mipscore_init) have some problem :
it configure some device on some irq without checking that the irq is not taken by an other device.
For example in my case PCI host is on irq 0 and IPSEC on irq 3.
The current code :
- store in dev->irq that IPSEC irq is 3+2
- do a set_irq 0->3 on PCI host
But now IPSEC irq is not routed anymore to the mips code and dev->irq is wrong. This cause problem described in [1].
This patch try to solve the problem by making set_irq configure the device we want to take the irq on the shared irq0.
The previous example become :
- store in dev->irq that IPSEC irq is 3+2
- do a set_irq 0->3 on PCI host :
- irq 3 is already taken by IPSEC. do a set_irq 3->0 on IPSEC
I also added some code to print the irq configuration before and after irq setup to allow easier debugging. And I add extra checking in ssb_mips_irq to report device without irq or device with not routed irq.

MIPS: Rewrite <asm/div64.h> to work with gcc 4.4.0.
The inline assembler used on 32-bit kernels was using the "h" constraint
which was considered dangerous and removed for gcc 4.4.0.

From: Wu Zhangjin <wuzj@lemote.com>
the gcc 4.4 support for MIPS mostly refer to this PATCH:
http://www.nabble.com/-PATCH--MIPS:-Handle-removal-of-%27h%27-constraint-in-GCC-4.4-td22192768.html
but have been tuned a little.
because only gcc 4.4 have loongson-specific support, so, we need to
choose the suitable -march argument for gcc <= 4.3 and gcc >= 4.4, and
we also need to consider use -march=loongson2e and -march=loongson2f for
loongson2e and loongson2f respectively. this is handled by adding two
new kernel options: CPU_LOONGSON2E and CPU_LOONGSON2F(thanks for the
solutin provided by ZhangLe).
I have tested it on FuLoong(2f) in 32bit and 64bit with gcc-4.4 and
gcc-4.3. so, basically, it works.

MIPS: allow disabling the kernel FPU emulator

From 819b4bda18d62b52d04789c4a8d4fc3fbf9ce242 Mon Sep 17 00:00:00 2001
From: Gabor Juhos <juhosg@openwrt.org>
Date: Mon, 13 Jul 2009 10:46:49 +0200
Subject: [PATCH] MIPS: fix loading of modules with unresolved weak symbols
Loading of modules with unresolved weak symbols fails on MIPS
since '88173507e4fc1e7ecd111b0565e8cba0cb7dae6d'.
Modules: handle symbols that have a zero value
The module subsystem cannot handle symbols that are zero. If symbols
are present that have a zero value then the module resolver prints out a
message that these symbols are unresolved.
We have to use IS_ERR_VALUE() to check that a symbol has been resolved
or not.
