2023-01-11powerpc/boot: Fix incorrect version calculation issue in ld_versionOjaswin Mujoo1-0/+4
The ld_version() function computes the wrong version value for certain ld versions such as the following: $ ld --version GNU ld (GNU Binutils; SUSE Linux Enterprise 15) 2.37.20211103-150100.7.37 For input 2.37.20211103, the value computed is 202348030000 which is higher than the value for a later version like 2.39.0, which is 23900000. This issue was highlighted because with the above ld version, the powerpc kernel build started failing with ld error: "unrecognized option --no-warn-rwx-segments". This was caused due to the recent commit 579aee9fc594 ("powerpc: suppress some linker warnings in recent linker versions") which added the --no-warn-rwx-segments linker flag if the ld version is greater than 2.39. Due to the bug in ld_version(), ld version 2.37.20111103 is wrongly calculated to be greater than 2.39 and the unsupported flag is added. To fix it, if version is of the form x.y.z and length(z) == 8, then most probably it is a date [yyyymmdd] commonly used for release snapshots and not an actual new version. Hence, ignore the date part replacing it with 0.

2022-09-28kbuild: build init/built-in.a just onceMasahiro Yamada1-1/+1
Kbuild builds init/built-in.a twice; first during the ordinary directory descending, second from scripts/link-vmlinux.sh. We do this because UTS_VERSION contains the build version and the timestamp. We cannot update it during the normal directory traversal since we do not yet know if we need to update vmlinux. UTS_VERSION is temporarily calculated, but omitted from the update check. Otherwise, vmlinux would be rebuilt every time. When Kbuild results in running link-vmlinux.sh, it increments the version number in the .version file and takes the timestamp at that time to really fix UTS_VERSION. However, updating the same file twice is a footgun. To avoid nasty timestamp issues, all build artifacts that depend on init/built-in.a are atomically generated in link-vmlinux.sh, where some of them do not need rebuilding. To fix this issue, this commit changes as follows: [1] Split UTS_VERSION out to include/generated/utsversion.h from include/generated/compile.h include/generated/utsversion.h is generated just before the vmlinux link. It is generated under include/generated/ because some decompressors (s390, x86) use UTS_VERSION. [2] Split init_uts_ns and linux_banner out to init/version-timestamp.c from init/version.c init_uts_ns and linux_banner contain UTS_VERSION. During the ordinary directory descending, they are compiled with __weak and used to determine if vmlinux needs relinking. Just before the vmlinux link, they are compiled without __weak to embed the real version and timestamp. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2021-08-26powerpc: retire sbc8548 board supportPaul Gortmaker1-1/+1
The support was for this was mainlined 13 years ago, in v2.6.25 [0e0fffe88767] just around the ppc --> powerpc migration. I believe the board was introduced a year or two before that, so it is roughly a 15 year old platform - with the CPU speed and memory size that was typical for that era. I haven't had one of these boards for several years, and availability was discontinued several years before that. Given that, there is no point in adding a burden to testing coverage that builds all possible defconfigs, so it makes sense to remove it. Of course it will remain in the git history forever, for anyone who happens to find a functional board and wants to tinker with it.

2018-03-25kbuild: Use ls(1) instead of stat(1) to obtain file sizeMichael Forney1-1/+1
stat(1) is not standardized and different implementations have their own (conflicting) flags for querying the size of a file. ls(1) provides the same information (value of st.st_size) in the 5th column, except when the file is a character or block device. This output is standardized[0]. The -n option turns on -l, which writes lines formatted like "%s %u %s %s %u %s %s\n", <file mode>, <number of links>, <owner name>, <group name>, <size>, <date and time>, <pathname> but instead of writing the <owner name> and <group name>, it writes the numeric owner and group IDs (this avoids /etc/passwd and /etc/group lookups as well as potential field splitting issues). The <size> field is specified as "the value that would be returned for the file in the st_size field of struct stat". To avoid duplicating logic in several locations in the tree, create scripts/file-size.sh and update callers to use that instead of stat(1).

The legazy --no-gzip and -z options are still supported and will set the compression to none and gzip respectively, but they are not documented. Only XZ -6 is used for compression rather than XZ -9. Using compression levels higher than 6 requires the decompressor to build a large (64MB) dictionary when decompressing and some environments cannot satisfy such large allocations (e.g. POWER 6 LPAR partition firmware).

Finally, the zImage file is compiled as a position independent executable (-pie) which makes it loadable at any address by the firmware.

2014-04-28powerpc/boot: Add a global entry point for pseriesCédric Le Goater1-1/+1
When entering the boot wrapper in little endian, we will need to fix the endian order using a fixup trampoline like in the kernel. This patch overrides the _zimage_start entry point for this purpose.

2014-01-10powerpc/embedded6xx: Add support for Motorola/Emerson MVME5100Stephen Chivers1-0/+4
Add support for the Motorola/Emerson MVME5100 Single Board Computer. 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.

2013-11-05powerpc/boot: Properly handle the base "of" boot wrapperBenjamin Herrenschmidt1-0/+4
The wrapper script needs an explicit rule for the "of" boot wrapper (generic wrapper, similar to pseries). Before 0c9fa29149d3726e14262aeb0c8461a948cc9d56 it was hanlded implicitly by the statement: platformo=$object/"$platform".o But now that epapr.o needs to be added, that doesn't work and an explicit rule must be added.

2013-10-30powerpc/boot: Don't change link address for OF-based platformsPaul Mackerras1-0/+4
Commit c55aef0e5bc6 ("powerpc/boot: Change the load address for the wrapper to fit the kernel") adjusts the wrapper address unnecessarily for platforms that use arch/powerpc/boot/of.c, since the code there allocates space for the kernel wherever it can find it and doesn't necessarily load the kernel at address 0. Changing the link address is actually harmful since it can cause the zImage to overlap with Open Firmware and thus fail to boot. To fix this, we set make_space to n for all of the platforms that use of.o. Signed-off-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

commit c55aef0e5bc6 ("powerpc/boot: Change the load address for the wrapper to fit the kernel") introduced a WARNING to inform the user that the uncompressed kernel would overlap the boot uncompressing wrapper code.

2011-12-20powerpc/boot: Change the load address for the wrapper to fit the kernelSuzuki Poulose1-0/+20
The wrapper code which uncompresses the kernel in case of a 'ppc' boot is by default loaded at 0x00400000 and the kernel will be uncompressed to fit the location 0-0x00400000. But with dynamic relocations, the size of the kernel may exceed 0x00400000(4M). This would cause an overlap of the uncompressed kernel and the boot wrapper, causing a failure in boot. The message looks like : zImage starting: loaded at 0x00400000 (sp: 0x0065ffb0) Allocating 0x5ce650 bytes for kernel ... Insufficient memory for kernel at address 0! (_start=00400000, uncompressed size=00591a20) This patch shifts the load address of the boot wrapper code to the next higher MB, according to the size of the uncompressed vmlinux. With the patch, we get the following message while building the image : WARN: Uncompressed kernel (size 0x5b0344) overlaps the address of the wrapper(0x400000) WARN: Fixing the link_address of wrapper to (0x600000) Signed-off-by: Suzuki K.

2011-12-08powerpc: Add support for OpenBlockS 600Benjamin Herrenschmidt1-1/+21
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.

2011-04-20powerpc/boot: Add an ePAPR compliant boot wrapperDavid Gibson1-0/+4
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.

2011-04-20powerpc/boot: Allow building the zImage wrapper as a relocatable ET_DYNMichael Ellerman1-3/+6
This patch adds code, linker script and makefile support to allow building the zImage wrapper around the kernel as a position independent executable. This results in an ET_DYN instead of an ET_EXEC ELF output file, which can be loaded at any location by the firmware and will process its own relocations to work correctly at the loaded address. This is of interest particularly since the standard ePAPR image format must be an ET_DYN (although this patch alone is not sufficient to produce a fully ePAPR compliant boot image). Note for now we don't enable building with -pie for anything.
