Currently, MIPS kernels silently overwrite kernel command-line parameters
hardcoded in CONFIG_CMDLINE by the ones received from firmware.  Therefore,
using firmware remains the only reliable method to transfer the
command-line parameters, which is not always desirable or convenient, and
the CONFIG_CMDLINE option is thereby effectively rendered useless.

This patch fixes the problem described above and introduces a more flexible
scheme of handling the kernel command line, in a manner identical to what is
currently used for x86.  The default behavior, i.e. when CONFIG_CMDLINE_BOOL
is not defined, retains the existing semantics, and firmware command-line
arguments override the hardcoded ones.

[Ralf: I fixed up all the defconfig files so the stay unaffected by this
change.]

 The SWARM defconfig file has not been regenerated for over a year now.
Here is a patch to bring the file up to date.  Additionally some important
and sometimes confusing changes happened meanwhile.  Here is the list of
notable corresponding updates to the configuration:

1. CPU_SB1_PASS_2_2 is now selected rather than CPU_SB1_PASS_1.  The
   latter requires a non-standard -msb1-pass1-workarounds option to be
   supported by GCC and I am told is quite rare anyway.

   [Ralf: Afaik -msb1-pass1-workarounds is available only in Monta Vista's
   special Sibyte gcc 3.0 variant and gcc 3.0 is too old to build a modern
   kernel anyway.]

2. PHYLIB and BROADCOM_PHY are both built in and NETDEV_1000 enabled as
   required by SB1250_MAC.

3. USB and USB_OHCI_HCD are enabled as there is an OHCI chip onboard.

4. TMPFS is enabled, because I use it. ;-)

The Qemu platform was originally implemented to have an easily supportable
platform until Qemu reaches a state where it emulates a real world system.
Since the latest release Qemu is capable of emulating the MIPSsim and
Malta platforms, so this goal has been reached.  The Qemu plaform is also
rather underfeatured so less useful than a Malta emulation.

This patch adds trivial support for SMARTMIPS extension. This extension
is currently implemented by 4KS[CD] CPUs.

Basically it saves/restores ACX register, which is part of the SMARTMIPS
ASE, when needed. This patch does *not* add any support for Smartmips MMU
features.

Futhermore this patch does not add explicit support for 4KS[CD] CPUs since
they are respectively mips32 and mips32r2 compliant.  So with the current
processor configuration, a platform that has such CPUs needs to select
both configs:

	CPU_HAS_SMARTMIPS
	SYS_HAS_CPU_MIPS32_R[12]

This is due to the processor configuration which is mixing up all the
architecture variants and the processor types.

The drawback of this, is that we currently pass '-march=mips32' option to
gcc when building a kernel instead of '-march=4ksc' for 4KSC case. This
can lead to a kernel image a little bit bigger than required.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
