2014-09-25powerpc/boot: Don't install zImage.* from make installTony Breeds
in commit 29f1aff2c (powerpc: Copy bootable images in the default install script) we changed to copying all the built boot targets based on the assumption that it's backwards compatible. It turns out that debian devived installkernel scripts will barf if not given exactly 4 args. This change reverts make install to just install the vmlinux (we can change the dfault in a seperate patch) and introduces a new make zInstall which works with a more flexible installkernel script.

2014-06-12powerpc: Avoid circular dependency with zImage.%Michal Marek
The rule to create the final images uses a zImage.% pattern. Unfortunately, this also matches the names of the zImage.*.lds linker scripts, which appear as a dependency of the final images. This somehow worked when $(srctree) used to be an absolute path, but now the pattern matches too much. List only the images from $(image-y) as the target of the rule, to avoid the circular dependency.

2014-04-28powerpc/boot: Add support for 64bit little endian wrapperCédric Le Goater
The code is only slightly modified : entry points now use the FIXUP_ENDIAN trampoline to switch endian order. The 32bit wrapper is kept for big endian kernels and 64bit is enforced for little endian kernels with a PPC64_BOOT_WRAPPER config option. The linker script is generated using the kernel preprocessor flags to make use of the CONFIG_* definitions and the wrapper script is modified to take into account the new elf64ppc format. Finally, the zImage file is compiled as a position independent executable (-pie) which makes it loadable at any address by the firmware.

2014-03-07powerpc: Delete old PrPMC 280/2800 supportPaul Gortmaker
This processor/memory module was mostly used on ATCA blades and before that, on cPCI blades. It wasn't really user friendly, with custom non u-boot bootloaders (powerboot/motload) and no real way to recover corrupted boot flash (which was a common problem). As such, it had its day back before the big ppc --> powerpc move to device trees, and that was largely through commercial BSPs that started to dry up around 2007. Systems using one were largely in a "deploy and sustain" mode, so interest in upgrading to new kernels in the field was nil. Also, requiring 50A, 48V power supplies and a 2'x2'x2' ATCA chassis largely rules out any hobbyist/enthusiast interest. The point of all this, is that we might as well delete the in kernel files relating to this platform. No point in continuing to build it via walking the defconfigs or via linux-next testing.

The MVME5100 is a 6U form factor VME64 computer with: - A single MPC7410 or MPC750 CPU - A HAWK Processor Host Bridge (CPU to PCI) and MultiProcessor Interrupt Controller (MPIC) - Up to 500Mb of onboard memory - A M48T37 Real Time Clock (RTC) and Non-Volatile Memory chip - Two 16550 compatible UARTS - Two Intel E100 Fast Ethernets - Two PCI Mezzanine Card (PMC) Slots - PPCBug Firmware The HAWK PHB/MPIC is compatible with the MPC10x devices. There is no onboard disk support. This is usually provided by installing a PMC in first PMC slot. This patch revives the board support, it was present in early 2.6 series kernels. The board support in those days was by Matt Porter of MontaVista Software. CSC Australia has around 31 of these boards in service. The kernel in use for the boards is based on 2.6.31. The boards are operated without disks from a file server. This patch is based on linux-3.13-rc2 and has been boot tested. Only boards with 512 Mb of memory are known to work.

This hooks dtc into Kbuild's dependency system. Thus, for example, "make dtbs" will rebuild tegra-harmony.dtb if only tegra20.dtsi has changed yet tegra-harmony.dts has not.

I'm not familiar enough with other architectures to know what to add there. Powerpc appears to already add various .dtb files into $(targets), but the other archs may need something added to $(targets) to work.

2010-01-13zlib: Fix build of powerpc boot wrapperBenjamin Herrenschmidt
Commit ac4c2a3bbe5db5fc570b1d0ee1e474db7cb22585 broke the build of all powerpc boot wrappers. It attempts to add an include of autoconf.h but used the wrong path for it. It also adds -D__KERNEL__ to our boot wrapper, both things that we pretty much didn't do on purpose so far. We want our boot wrapper to remain independent enough of the kernel for various reasons, one of them being that you can "wrap" an existing kernel at distro install time which allows to ship one kernel image and a set of boot wrappers for different platforms, the wrappers don't have to be built out of the same kernel build tree. It's also incorrect to do what the patch does in our boot environment since we may not have a proper alignment exception handler which means we may not be able to fixup the few cases where an unaligned access will need SW emulation (depends on the core variant, could be when crossing page or segment boundaries for example). This patch fixes it by putting the old code back in and using the new "fancy" variant only when CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS is set, which happens not to be set on powerpc since we don't include autoconf.h. It also reverts the changes to our boot wrapper Makefile. This means that x86 should, afaik, keep the optimisations since its boot wrapper does include autoconf.h and define __KERNEL__ (though I doubt they make that much different outside of slow embedded processors).

2009-05-02Move dtc and libfdt sources from arch/powerpc/boot to scripts/dtcDavid Gibson
The powerpc kernel always requires an Open Firmware like device tree to supply device information. On systems without OF, this comes from a flattened device tree blob. This blob is usually generated by dtc, a tool which compiles a text description of the device tree into the flattened format used by the kernel. Sometimes, the bootwrapper makes small changes to the pre-compiled device tree blob (e.g. filling in the size of RAM). To do this it uses the libfdt library. Because these are only used on powerpc, the code for both these tools is included under arch/powerpc/boot (these were imported and are periodically updated from the upstream dtc tree). However, the microblaze architecture, currently being prepared for merging to mainline also uses dtc to produce device tree blobs. A few other archs have also mentioned some interest in using dtc. Therefore, this patch moves dtc and libfdt from arch/powerpc into scripts, where it can be used by any architecture. The vast bulk of this patch is a literal move, the rest is adjusting the various Makefiles to use dtc and libfdt correctly from their new locations.

2009-01-08powerpc: Copy bootable images in the default install scriptGrant Likely
This patch makes the default install script (arch/powerpc/boot/install.sh) copy the bootable image files into the install directory. Before this patch only the vmlinux image file was copied. This patch makes the default 'make install' command useful for embedded development when $(INSTALL_PATH) is set in the environment. As a side effect, this patch changes the calling convention of the install.sh script. Instead of a single 5th parameter, the script is now passed a list of all the target images stored in the $(image-y) Makefile variable. This should be backwards compatible with existing install scripts since it just adds additional arguments and does not change existing ones.

2008-12-22powerpc/cell: add QPACE as a separate Cell platformBenjamin Krill
Since the QPACE (Chromodynamics Parallel Computing on the Cell Broadband Engine) platform doesn't use a iommu, doesn't have PCI devices and a MPIC much lesser setup and configurations are needed. So far all devices are detected as OF device. A notifier function is used to set the dma_ops for the of_platform bus. Further this patch splits the PPC_CELL_NATIVE into PPC_CELL_COMMON which are parts that are shared with the QPACE platform and the rest.

2008-12-11powerpc/40x: Add proper BOOTCFLAGS for cuboot-acadiaJosh Boyer
The cuboot-acadia.c wrapper can cause assembler errors on some toolchains due to the lack of the proper BOOTCFLAGS. This adds the proper flags for the file. Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>

2008-09-17powerpc: Holly board needs dtbImage targetJosh Boyer
One of the changes in the bootwrapper makefile introduced the dtbImage targets for boards that need a simple zImage with a DTB embedded in them (595be948cce574ff2d5dde5d0426a636a4363c70, "[POWERPC] bootwrapper: Build multiple cuImages"). When this was done, it broke booting on the Holly board as the zImage.holly wrapper did not get the DTB embedded properly. This changes the target for the Holly board to a dtbImage so that the wrapper includes the vmlinux, wrapper bits, and DTB.
