2005-10-26powerpc: Fixes to get the Longtrail CHRP a bit furtherPaul Mackerras
Talk about buggy firmware... the OF on the Longtrail returns 0 from the claim client service rather than -1 when the claim fails. It also has no device_type on the /memory node and blows up if the output buffer for package-to-path is too big. This also fixes a bug with calling alloc_up with align == 0, where we did _ALIGN_UP(alloc_bottom, 0) which will end up as 0. Lastly, we now check the return value (in r3) from calling the prom, and return -1 from call_prom if we get a negative value back. That is supposed to indicate that the requested client service doesn't exist. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-23powerpc: Make coff boot wrapper load the kernel at 8MPaul Mackerras
Previously it claimed 7MB starting at the 9M point and loaded the kernel there. That meant that prom_init put the flattened device tree above 16M. On the 601 that caused the early device tree scan to fail, since only 16MB are mapped with BATs on the 601. Moving this down to 8MB allows prom_init to put the flattened device tree between 15M and 16M, so it works on the 601. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-09-29[PATCH] ppc32 ld.script fix for building on ppc64Al Viro
In arch/ppc/boot/ld.script we need OUTPUT_ARCH(powerpc:common) for the same reasons why we need it in vmlinux.lds.S; when we build on ppc64 box, we need to be explicit about the target. See http://linus.bkbits.net:8080/linux-2.5/cset@1.1784.8.10 for the corresponding fix in vmlinux.lds.S.

2005-09-09[PATCH] ppc32: In the boot code, don't rely on BASE_BAUD directlyTom Rini
Modifies serial_init to get base baud rate from the rs_table entry instead of BAUD_BASE. This patch eliminates duplication between the SERIAL_PORT_DFNS macro and BAUD_BASE. Without the patch, if a port set the baud rate in SERIAL_PORT_DFNS, but did not update BASE_BAUD, the BASE_BAUD value would still be used.

2005-08-29[PATCH] Remove NACA fixed address constraintDavid Gibson
Comments in head.S suggest that the iSeries naca has a fixed address, because tools expect to find it there. The only tool which appears to access the naca is addRamDisk, but both the in-kernel version and the version used in RHEL and SuSE in fact locate the NACA the same way as the hypervisor does, by following the pointer in the hvReleaseData structure. Since the requirement for a fixed address seems to be obsolete, this patch removes the naca from head.S and replaces it with a normal C initializer. For good measure, it removes an old version of addRamDisk.c which was sitting, unused, in the ppc32 tree.

2005-06-21[PATCH] ppc32: Kill embedded system.map, use kallsymsBenjamin Herrenschmidt
This patch kills the whole embedded System.map mecanism and the bootloader-passed System.map that was used to provide symbol resolution in xmon. Instead, xmon now uses kallsyms like ppc64 does.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
