2016-04-03MIPS: zboot: Fix the build with XZ compression on older GCC versionsAlban Bedel1-3/+3
Some older GCC version (at least 4.6) emits calls to __bswapsi2() when building the XZ decompressor. The link of the compressed image then fails with the following error: arch/mips/boot/compressed/decompress.o: In function '__fswab32': include/uapi/linux/swab.h:60: undefined reference to '__bswapsi2' Add bswapsi.o to the link to fix the build with these versions.

Ingenic SoC declares ZBOOT support, but debug definitions are missing for MACH_JZ4780 resulting in a build failure when DEBUG_ZBOOT is set. The UART addresses are same as with JZ4740, so fix by covering JZ4780 with those as well.

2016-01-24MIPS: zboot: Avoid useless rebuildsAlban Bedel1-6/+8
Add dummy.o to the targets list, and fill targets automatically from $(vmlinuzobjs) to avoid having to maintain two lists. When building with XZ compression copy ashldi3.c to the build directory to use a different object file for the kernel and zboot. Without this the same object file need to be build with different flags which cause a rebuild at every run.

2015-06-21MIPS: Add support for vmlinuz.bin appended dtbJonas Gorski2-1/+21
Add support for detecting a vmlinuz.bin appended dtb and overriding the boot arguments to match the UHI interface. To ensure _edata / __apendend_dtb points to the actual end of the binary, align the data section to 16 bytes instead of the address cursor. Due to ld.script not going through the preprocessor, we can't check for MIPS_ZBOOT_APPENDED_DTB being enabled, so always reserve space for it. It should have no consequences for booting without it enabled except 1 MiB more ram usage during the uncompressing stage.

2013-09-03MIPS: Refactor load/entry address calculationsJames Hogan1-1/+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.

2013-07-01MIPS: Boot: Compressed: Remove -fstack-protector from CFLAGSMarkos Chandras1-0/+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' [[email protected]: I'm applying this before the patch that actually adds stack protector support for MIPS.

2010-01-28MIPS: Fix vmlinuz build for 32bit-only math shellsAlexander Clouter1-2/+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 <[email protected]> Acked-by: Wu Zhangjin <[email protected]> Patchwork: http://patchwork.linux-mips.org/patch/861/ Signed-off-by: Ralf Baechle <[email protected]>

2010-01-12MIPS: Cleanup and Fixup of compressed kernel supportWu Zhangjin3-155/+59
o Remove the .initrd section. 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. Tested with GCC 3.4.6 and 4.4.1 with and without initrd.

2009-12-17MIPS: Add support for GZIP / BZIP2 / LZMA compressed kernel imagesWu Zhangjin7-0/+516
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.
