Panic() invokes printk() to add a \n internally, so panic arguments should
not themselves end in \n. Panic invocations in arch/mips and elsewhere
are inconsistently sometimes terminating in \n, sometimes not.Signed-off-by: Ralf Baechle

Prepare bcm47xx to support different System buses. Before adding
support for bcma it should be possible to build bcm47xx without the
need of ssb. With this patch bcm47xx does not directly contain a
ssb_bus, but a union contain all the supported system buses. As a SoC
just uses one system bus a union is a good choice.Signed-off-by: Hauke Mehrtens

Some members of the struct ssb_sprom where not filled with data available
in the NVRAM. Some attribute names in the NVRAM changed from SPROM version
3 to version 4. This patch was done by analyzing the the pci sprom parser
in the ssb code and some open source parts of the braodcom wireless driver
used on embedded devices.Signed-off-by: Hauke Mehrtens

We are generating the prefix based on the PCI bus address the device is
on. This is done like Broadcom does it in their code expect that the the
bus number is increased by one. In the SB bus implementation used by
Broadcom the SB bus emulates a PCI bus so the kernel sees one PCI bus
more then in our implementation. We do not handle prefixes like sb/1/
yet as they are only used on the new bus which is not implemented yet.Signed-off-by: Hauke Mehrtens

When an other SSB based device without an own SPROM is attached, using the
PCI bus to the main SSB based device, the data normally found in the SPROM
will be stored in the NVRAM on modern devices. The keys, to load the data
from the NVRAM, are all using some sort of prefix like pci/1/1/, pci/1/3/
or sb/1/ before the actual key. This patch extends bcm47xx_fill_sprom() to
make it possible to read out these values when some prefix was used.The keys for the SPROM data used on the main chip does not have a prefix.

The previous patch 4a86f2d27733f610e642649aca3e82e86fca9e22 (lmo) rsp.
84a6fcb368a080620d12fc4d79e07902dbee7335 (kernel.org) was wrong.The BCM47xx architecture maps the ram into a 128MB address space. It
will be spaced there as often as goes into the 128MB. Detection tries to
find the position where the same memory is found. When reading beyond
128MB the processor will throw an exception. If 128MB RAM is installed,
it will not find a memory alias because it tries to read beyond the 128MB
border. Now it just assumes 128MB installed ram if it can not find an
alias.Signed-off-by: Hauke Mehrtens

When trying to netboot a Linksys WRT54GS WLAN router, the bootup fails,
because of following error message:...
[ 0.424000] b44: b44.c:v2.0
[ 0.424000] b44: Invalid MAC address found in EEPROM
[ 0.432000] b44 ssb0:1: Problem fetching invariants of chip,aborting
[ 0.436000] b44: probe of ssb0:1 failed with error -22
...The router uses a CFE bootloader, but most of the needed environment
variables for network card initialization, are not available from CFE
via printenv and even though not via cfe_getenv().
The required environment variables are saved in a special partition
in flash memory. The attached patch implement nvram_getenv and enables
bootup via NFS root on my router.Most of the patch is extracted from the OpenWrt subversion repository and
stripped down and cleaned up to just fix this issue.[Ralf: sorted out header file inclusions. Lots of unneded headers and such
that should have been included.]Signed-off-by: Waldemar Brodkorb

The MIPS-specific macro CL_SIZE is merely aliasing the macro
COMMAND_LINE_SIZE. Other architectures use the latter; also,
COMMAND_LINE_SIZE is documented in kernel-parameters.txt, so
let's use it, and remove the alias.Signed-off-by: Dmitri Vorobiev

Since commit 22242681cff52bfb7cba5d2a37b91802be7a4e4c ("MIPS: Extend
COMMAND_LINE_SIZE"), CL_SIZE is 4096 and local array variables with this
size will cause an build failure with default CONFIG_FRAME_WARN settings.Although current users of such array variables are all early bootstrap
code and not likely to cause real stack overflow (thread_info corruption),
it is preferable to to declare these arrays static with __initdata.Signed-off-by: Atsushi Nemoto
