* MIPS: Octeon: Move device-trees to arch/mips/boot/dts/Andrew Bresticker2014-09-223-0/+1217
| | | | | | | | | | | | | | | | | | | | | | | | Move the Octeon device-trees to arch/mips/boot/dts/ and update the Makefiles accordingly. Since Octeon requires the device-tree to be built into the kernel, select BUILTIN_DTB as well.

* MIPS: Add uImage build targetJames Hogan2013-09-032-0/+16
| | | | | | | | | | | | | | | | | | | Add a uImage build target for MIPS, which builds uImage.gz (a U-Boot image of vmlinux.bin.gz), and then symlinks it to uImage. This allows for the use of other compression algorithms in future, and is how a few other architectures do it. It's enabled conditionally on load-y >= 0xffffffff80000000 which hopefully allows 64bit kernels to also work as long as the load and entry address can be represented by the 32bit addresses in the U-Boot image format.

* MIPS: Refactor load/entry address calculationsJames Hogan2013-09-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The vmlinux load address and entry address is calculated in multiple places: - arch/mips/Makefile defines load-y from CONFIG_PHYSICAL_START (or defined by the platform) and passes it to arch/mips/boot/compressed/Makefile. - arch/mips/boot/compressed/Makefile calculates kernel entry using nm. - arch/mips/lasat/image/Makefile calculates both load and entry address using nm. Lets combine these in the main Makefile and then pass them as Make parameters to each of the three boot image Makefiles (in boot/, boot/compressed, lasat/image/). The boot/ Makefile doesn't currently use them, but will soon need to for U-Boot image targets. The existing load-y definition is used in preference to calculating the load address using nm.

* MIPS: add <dt-bindings/> symlinkJames Hogan2013-09-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add symlink to include/dt-bindings from arch/mips/boot/dts/include/ to match the ones in ARM and Meta architectures so that preprocessed device tree files can include various useful constant definitions. See commit c58299a (kbuild: create an "include chroot" for DT bindings) merged in v3.10-rc1 for details. MIPS structures it's dts files a little differently to other architectures, having a separate dts directory for each SoC/platform, but most of the definitions in the dt-bindings/ directory are common so for now lets just have a single "include chroot" for all MIPS platforms.

* MIPS: Boot: Compressed: Remove -fstack-protector from CFLAGSMarkos Chandras2013-07-011-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | When building with -fstack-protector, gcc emits the __stack_chk_guard and __stack_chk_fail symbols to check for stack stability. These symbols are defined in vmlinux but the generated vmlinux.bin that is used to create the compressed vmlinuz image has no symbol table so the linker can't find these symbols during the final linking phase. As a result of which, we need either to redefine these symbols just for the compressed image or drop the -fstack-protector option when building the compressed image. This patch implements the latter of two options. Fixes the following linking problem: dbg.c:(.text+0x7c): undefined reference to `__stack_chk_guard' dbg.c:(.text+0x80): undefined reference to `__stack_chk_guard' dbg.c:(.text+0xd4): undefined reference to `__stack_chk_guard' dbg.c:(.text+0xec): undefined reference to `__stack_chk_fail' [ralf@linux-mips.org: I'm applying this before the patch that actually adds stack protector support for MIPS. This means, it will not be possible to trigger above error message with any commit from the tree but rather they are what one would hit without this commit.] Signed-off-by: Markos Chandras <markos.chandras@imgtec.com> Cc: linux-mips@linux-mips.org Cc: Markos Chandras <markos.chandras@imgtec.com> Patchwork: https://patchwork.linux-mips.org/patch/5575/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

| | | | | | | | | | | | | | | | | | | | - use hostprogs-y for the elf2ecoff - list all *.o file in targets - renamed obj-y to vmlinuzobjs-y (it was confusing to re-use a kbuild variable) - fix all uses of if_changed/cmd - use kbuild rules to beautify output - update clean-file to clean vmlinuz.* in top-level directory - simplied logic in arch/mips/Makefile for compressed targets The net result is a more kbuild conformant Makefile but readability did not increase.

* MIPS: Make the debugging of compressed kernel configurableWu Zhangjin2010-02-271-0/+2
| | | | | | | | | | | | | | This patch adds a new DEBUG_ZBOOT option to allow the users to enable it to debug the compressed kernel support for a new board and this optoin should be disabled to reduce the kernel image size and speed up the kernel booting procedure when the compressed kernel support is stable.

* MIPS: Fix vmlinuz build for 32bit-only math shellsAlexander Clouter2010-01-281-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | POSIX requires $((<expression>)) arithmetic in sh only to have long arithmetic so on 32-bit sh binaries might do only 32-bit arithmetic but the arithmetic done in arch/mips/boot/compressed/Makefile needs 64-bit. I play with the AR7 platform, so VMLINUX_LOAD_ADDRESS is 0xffffffff94100000, and for an example 4MiB kernel VMLINUZ_LOAD_ADDRESS is made out to be: ---- alex@berk:~$ bash -c 'printf "%x\n" $((0xffffffff94100000 + 0x400000))' ffffffff94500000 alex@berk:~$ dash -c 'printf "%x\n" $((0xffffffff94100000 + 0x400000))' 80000000003fffff ---- The former is obviously correct whilst the later breaks things royally. Fortunately working with only the lower 32bit's works for both bash and dash: ---- $ bash -c 'printf "%x\n" $((0x94100000 + 0x400000))' 94500000 $ dash -c 'printf "%x\n" $((0x94100000 + 0x400000))' 94500000 ---- So, we can split the original 64bit string to two parts, and only calculate the low 32bit part, which is big enough (1GiB kernel sizes anyone?) for a normal Linux kernel image file, now, we calculate the VMLINUZ_LOAD_ADDRESS like this: 1. if present, append top 32bit of VMLINUX_LOAD_ADDRESS" as a prefix 2. get the sum of the low 32bit of VMLINUX_LOAD_ADDRESS + VMLINUX_SIZE This patch fixes vmlinuz kernel builds on systems where only a 32bit-only math shell is available. Patch Changelog: Version 2 - simplified method by using 'expr' for 'substr' and making it work with dash once again Version 1 - Revert the removals of '-n "$(VMLINUX_SIZE)"' to avoid the error of "make clean" - Consider more cases of the VMLINUX_LOAD_ADDRESS Version 0 - initial release Signed-off-by: Alexander Clouter <alex@digriz.org.uk> Acked-by: Wu Zhangjin <wuzhangjin@gmail.com> Patchwork: http://patchwork.linux-mips.org/patch/861/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

The initrd section was already handled when vmlinux was linked. o Discard .MIPS.options, .options, .pdr, .reginfo, .comment and .note sections. If .MIPS.options is not removed, kernels compiled with gcc 3.4.6 will not boot. o Clean up the file format. o Remove several other unneeded sections.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch helps to generate smaller kernel images for linux-MIPS, Here is the effect when using lzma: $ ls -sh vmlinux 7.1M vmlinux $ ls -sh vmlinuz 1.5M vmlinuz Have tested the 32bit kernel on Qemu/Malta and 64bit kernel on FuLoong Mini PC. both of them work well. and also, tested by Alexander Clouter on an AR7 based Linksys WAG54Gv2, and by Manuel Lauss on an Alchemy board. This -v2 version incorporate the feedback from Ralf, and add the following changes: 1. add .ecoff, .bin, .erec format support 2. only enable it and the debug source code for the machines we tested 3. a dozen of fixups and cleanups and if you want to enable it for your board, please try to select SYS_SUPPORTS_ZBOOT for it, and if the board have an 16550 compatible uart, you can select SYS_SUPPORTS_ZBOOT_UART16550 directly. and then sending the relative patches to Ralf.
