I've got a working system for a Broadcom SB1, thanks
to the considerable help (and patches) from here, and
the helpful step-through on Linux From Scratch.
However, I've subsequently run into a problem when
upgrading the kernel, using the version in CVS on the
Linux-MIPS site. (I'm applying the same set of
patches, am using the same .config file, and have not
changed the toolchain. That's next on my list.)
The version in CVS on September 22nd
(linux-2.6.14-rc1-mipscvs-20050922) compiles fine.
The version currently in CVS
(linux-2.6.14-rc1-mipscvs-20051011) crashes out with
the following errors:
make
CHK include/linux/version.h

If I delete lines 339-441 - which do a
BUILDIO_IOPORT(q, u64), conditional on it being a
64-bit compile - then the kernel will compile. I do,
however, get the following warnings:
include/asm/io.h: In function 'outsq':
include/asm/io.h:517: warning: implicit declaration of
function 'mem_outq'
include/asm/io.h: In function 'insq':
include/asm/io.h:517: warning: implicit declaration of
function 'mem_inq'
I'm guessing that the BUILDIO_IOPORT() is setting up
these calls, but it's not quite clear to me as to
where.
The only obvious difference in the macro call from any
of the other macros in that group is the use of u64.
Declaring a dummy variable at the start of the header
file of this type does not produce any warnings or
errors, so I'm satisfied that the type definition
exists.
An inspection of the .config file verifies that the
CPU is declared as an SB1, and that it is a 64-bit
kernel build.
Any ideas?
