| * Kbuild: Use dtc's -d (dependency) optionStephen Warren2012-01-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. The previous lack of this feature recently caused me to have very confusing "git bisect" results. For ARM, it's obvious what to add to $(targets). 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.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So I've had one of these for a while and it looks like the vendor never bothered submitting the support upstream. This adds it using ppc40x_simple and provides a device-tree. There are some changes to the boot wrapper because the way u-boot works on this thing, it seems to expect a multipart image with the kernel, initrd and dtb in it. The USB support is missing as it needs the yet unmerged driver for the DWC OTG part and the GPIOs may need further definition in the dts.

* | powerpc: Add skeleton PowerNV platformBenjamin Herrenschmidt2011-09-201-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a skeletton for the new Power "Non Virtualized" platform which will be used by machines supporting running without an hypervisor, for example in order to run KVM. These machines will be using a new firmware called OPAL for which the support will be provided by later patches. The PowerNV platform is intended to be also usable under the BML environment used internally for early CPU bringup which is why the code also supports using RTAS instead of OPAL in various places.

* powerpc/boot: Add an ePAPR compliant boot wrapperDavid Gibson2011-04-201-1/+3
| | | | | | | | | | | | | | | | | | | | This is a first cut at making bootwrapper code which will produce a zImage compliant with the requirements set down by ePAPR. This is a very simple bootwrapper, taking the device tree blob supplied by the ePAPR boot program and passing it on to the kernel. It builds on the earlier patch to build a relocatable ET_DYN zImage to meet the other ePAPR image requirements. For good measure we have some paranoid checks which will generate warnings if some of the ePAPR entry condition guarantees are not met.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* zlib: optimize inffast when copying direct from outputJoakim Tjernlund2010-01-111-1/+3
| | | | | | | | | | | | | | | | | | | | | | JFFS2 uses lesser compression ratio and inflate always ends up in "copy direct from output" case. This patch tries to optimize the direct copy procedure. Uses get_unaligned() but only in one place. The copy loop just above this one can also use this optimization, but I havn't done so as I have not tested if it is a win there too. On my MPC8321 this is about 17% faster on my JFFS2 root FS than the original.

* | Move dtc and libfdt sources from arch/powerpc/boot to scripts/dtcDavid Gibson2009-05-021-44/+23
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* powerpc: Copy bootable images in the default install scriptGrant Likely2009-01-081-1/+1
| | | | | | | | | | | | | | | | | | | 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.

* | powerpc: Make the 64-bit kernel as a position-independent executablePaul Mackerras2008-09-151-0/+3
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | This implements CONFIG_RELOCATABLE for 64-bit by making the kernel as a position-independent executable (PIE) when it is set. This involves processing the dynamic relocations in the image in the early stages of booting, even if the kernel is being run at the address it is linked at, since the linker does not necessarily fill in words in the image for which there are dynamic relocations. (In fact the linker does fill in such words for 64-bit executables, though not for 32-bit executables, so in principle we could avoid calling relocate() entirely when we're running a 64-bit kernel at the linked address.) The dynamic relocations are processed by a new function relocate(addr), where the addr parameter is the virtual address where the image will be run. In fact we call it twice; once before calling prom_init, and again when starting the main kernel. This means that reloc_offset() returns 0 in prom_init (since it has been relocated to the address it is running at), which necessitated a few adjustments. This also changes __va and __pa to use an equivalent definition that is simpler. With the relocatable kernel, PAGE_OFFSET and MEMORY_START are constants (for 64-bit) whereas PHYSICAL_START is a variable (and KERNELBASE ideally should be too, but isn't yet). With this, relocatable kernels still copy themselves down to physical address 0 and run there. Signed-off-by: Paul Mackerras <paulus@samba.org>
