Ralf Baechle dd0bc75ee3 MIPS: SB1: Remove support for Pass 1 parts.
Pass 1 parts had a number of significant erratas and were only available
in small numbers and under NDA.  Full support also required the use of a
special toolchain that kept branches properly aligned.  These workarounds
were never upstreamed and the only toolchain known to have them is
Montavista's GCC 3.0-based toolchain which completly obsoleted if not
useless these days.

So now that automated testing has tripped over the user of the
-msb1-pass1-workarounds option, rather than fixing it remove support for
pass 1 parts.

Probably nobody will notice.  I seem to own the last know pass 1 board
and I haven't noticed another one in the wild in the past decade, at
least.

Ralf Baechle 67e38cf293 MIPS/IRQCHIP: Move irq_chip from arch/mips to drivers/irqchip.
While at it, rename it because in drivers/irqchip no longer every CPU is

Markos Chandras 6793f55cbc MIPS: sibyte: Amend dependencies for SIBYTE_BUS_WATCHER
SIBYTE_BUS_WATCHER is only visible if CONFIG_SIBYTE_BCM112X
or CONFIG_SIBYTE_SB1250 is selected according to the
arch/mips/sibyte/Makefile.
This fixes the following build problem:

arch/mips/mm/cerr-sb1.c:254: undefined reference to `check_bus_watcher'

Ralf Baechle 0e2794b0b7 MIPS: Kconfig: Rename several firmware related config symbols.
With the upcoming merge of the ARC architecture there is a small likelyhood
of conflicting use for the CONFIG_ARC config symbol.  Rename it to
CONFIG_FW_ARC.  Also rename CONFIG_ARC32 to CONFIG_FW_ARC32, CONFIG_ARC64
to CONFIG_FW_ARC64.

For consistence also rename CONFIG_SNIPROM to CONFIG_FW_SNIPROM and
CONFIG_CFE to CONFIG_FW_CFE.

Paul Bolle 63f722e629 MIPS: Sibyte: drop select of SIBYTE_CFE
SIBYTE_CFE got killed in commit 05f94eebd5 ("MIPS: Sibyte: Remove
standalone kernel support"). This means that since v2.6.31 there is no
Kconfig symbol SIBYTE_CFE. The select statement for that symbol is a
nop. Drop it.

Imre Kaloz 05f94eebd5 MIPS: Sibyte: Remove standalone kernel support
CFE is the only supported and used bootloader on the SiByte boards,
the standalone kernel support has been never used outside Broadcom.
Remove it and make the kernel use CFE by default.
