MIPS: Makefile: Fix MIPS ASE detection code

2015-05-13T12:14:23+00:00

Commit 5306a5450824691e27d68f711758515debedeeac upstream. Commit 32098ec7bcba ("MIPS: Makefile: Move the ASEs checks after setting the core's CFLAGS") re-arranged the MIPS ASE detection code and also added the current cflags to the detection logic. However, this introduced a few bugs. First of all, the mips-cflags should not be quoted since that ends up being passed as a string to subsequent commands leading to broken detection from the cc-option-* tools. Moreover, in order to avoid duplicating the cflags-y because of how cc-option works, we rework the logic so we pass only those cflags which are needed by the selected ASE. Finally, fix some typos resulting in MSA not being detected correctly.

MIPS: boot: Provide more uImage options

2015-02-20T13:17:43+00:00

Allow more compression algorithms as well as uncompressed uImage.bin to be generated. An uncompressed image might be useful to rule out problems in the decompression code in the bootloader or even speed up the boot process at the expense of a bigger uImage file.

MIPS: Makefile: Move the ASEs checks after setting the core's CFLAGS

2015-02-19T12:47:32+00:00

We need to check the ASEs support against the core's CFLAGS instead of depending to the default -march option from the toolchain. Signed-off-by: Markos Chandras Cc: Maciej W. Rozycki Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/9180/ Signed-off-by: Ralf Baechle

MIPS: Makefile: Pass -march option on Loongson3A cores

2015-02-19T12:47:20+00:00

The loongson 3A cores do not select a suitable -march option so the build system uses the default one from the toolchain. This may or may not be suitable for a loongson 3A build. In order to avoid that, we explicitly set a suitable -march option for that core. Furthermore, some very old compilers don't support -march= at all and there is the possibility of toolchain combinations such as GCC 4.9 and binutils 2.24 for which -march=loongson3a will result in MIPS64 R2 code being generated but then rejected by GAS. So treat the Longsoon 3A as an R2 CPU. Signed-off-by: Ralf Baechle

MIPS: Add build support for the MIPS R6 ISA

MIPS: IP22/IP32: Add line to arch/mips/Makefile archhelp about vmlinux.32

2014-11-24T06:45:33+00:00

Building a 64bit kernel for the SGI O2 (IP32) and the SGI Indy (IP22) uses the 'vmlinux.32' target, which converts the output 64-bit 'vmlinux' image into a 32-bit wrapped image. This is needed for certain revisions of the IP22 and IP32 ARCS PROMs to boot correctly, but this target is missing from the 'archhelp' info that is emitted by 'make help'.

MIPS: Fix build with binutils 2.24.51+

2014-11-07T14:07:36+00:00

Starting with version 2.24.51.20140728 MIPS binutils complain loudly about mixing soft-float and hard-float object files, leading to this build failure since GCC is invoked with "-msoft-float" on MIPS: {standard input}: Warning: .gnu_attribute 4,3 requires `softfloat' LD arch/mips/alchemy/common/built-in.o mipsel-softfloat-linux-gnu-ld: Warning: arch/mips/alchemy/common/built-in.o uses -msoft-float (set by arch/mips/alchemy/common/prom.o), arch/mips/alchemy/common/sleeper.o uses -mhard-float To fix this, we detect if GAS is new enough to support "-msoft-float" command option, and if it does, we can let GCC pass it to GAS; but then we also need to sprinkle the files which make use of floating point registers with the necessary ".set hardfloat" directives.
