* arm, cris, mips, sparc, powerpc, um, xtensa: fix build with bash 4.0Sam Ravnborg2009-09-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Albin Tonnerre <albin.tonnerre@free-electrons.com> reported: Bash 4 filters out variables which contain a dot in them. This happends to be the case of CPPFLAGS_vmlinux.lds. This is rather unfortunate, as it now causes build failures when using SHELL=/bin/bash to compile, or when bash happens to be used by make (eg when it's /bin/sh) Remove the common definition of CPPFLAGS_vmlinux.lds by pushing relevant stuff to either Makefile.build or the arch specific kernel/Makefile where we build the linker script. This is also nice cleanup as we move the information out where it is used. Notes for the different architectures touched: arm - we use an already exported symbol cris - we use a config symbol aleady available [Not build tested] mips - the jiffies complexity has moved to vmlinux.lds.S where we need it. Added a few variables to CPPFLAGS - they are only used by the linker script. [Not build tested] powerpc - removed assignment that is not needed [not build tested] sparc - simplified it using $(BITS) um - introduced a few new exported variables to deal with this xtensa - added options to CPP invocation [not build tested] Cc: Albin Tonnerre <albin.tonnerre@free-electrons.com> Cc: Russell King <linux@arm.linux.org.uk> Cc: Mikael Starvik <starvik@axis.com> Cc: Jesper Nilsson <jesper.nilsson@axis.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Paul Mackerras <paulus@samba.org> Cc: "David S.

* MIPS: Loongson: Add GCC 4.4 support for Loongson2EWu Zhangjin2009-09-17
| | | | | | | | | | | | | | | | Because only gcc >=4.4 have loongson-specific support, we need to choose the suitable -march argument for gcc <= 4.3 and gcc >= 4.4, and here, we use -march=loongson2e for loongson2e. Thanks goes to Arnaud Patard <apatard@mandriva.com> for suggestion of using cc-options(Documentation/kbuild/makefiles.txt). and thanks Zhang Le for introducing the new CPU_LOONGSON2E kernel option. NOTE: -mtune option is not need if -march and -mtune use the same value.

* MIPS: Alchemy: Rewrite GPIO support.Manuel Lauss2009-06-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current in-kernel Alchemy GPIO support is far too inflexible for all my use cases. To address this, the following changes are made: * create generic functions which deal with manipulating the on-chip GPIO1/2 blocks. Such functions are universally useful. * Macros for GPIO2 shared interrupt management and block control. * support for both built-in CONFIG_GPIOLIB and fast, inlined GPIO macros. If CONFIG_GPIOLIB is not enabled, provide linux gpio framework compatibility by directly inlining the GPIO1/2 functions. GPIO access is limited to on-chip ones and they can be accessed as documented in the datasheets (GPIO0-31 and 200-215). If CONFIG_GPIOLIB is selected, two (2) gpio_chip-s, one for GPIO1 and one for GPIO2, are registered. GPIOs can still be accessed by using the numberspace established in the databooks. However this is not yet flexible enough for my uses: My Alchemy systems have a documented "external" gpio interface (fixed, different numberspace) and can support a variety of baseboards, some of which are equipped with I2C gpio expanders. I want to be able to provide the default 16 GPIOs of the CPU board numbered as 0..15 and also support gpio expanders, if present, starting as gpio16. To achieve this, a new Kconfig symbol for Alchemy is introduced, CONFIG_ALCHEMY_GPIO_INDIRECT, which boards can enable to signal that they don't want the Alchemy numberspace exposed to the outside world, but instead want to provide their own. Boards are now respon- sible for providing the linux gpio interface glue code (either in a custom gpio.h header (in board include directory) or with gpio_chips). To make the board-specific inlined gpio functions work, the MIPS Makefile must be changed so that the mach-au1x00/gpio.h header is included _after_ the board headers, by moving the inclusion of the mach-au1x00/ to the end of the header list. See arch/mips/include/asm/mach-au1x00/gpio.h for more info.

* [MIPS] R4000/R4400 errata workaroundsMaciej W. Rozycki2008-01-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the gereric part of R4000/R4400 errata workarounds. They include compiler and assembler support as well as some source code modifications to address the problems with some combinations of multiply/divide+shift instructions as well as the daddi and daddiu instructions. Changes included are as follows: 1. New Kconfig options to select workarounds by platforms as necessary. 2. Arch top-level Makefile to pass necessary options to the compiler; also incompatible configurations are detected (-mno-sym32 unsupported as horribly intrusive for little gain). 3. Bug detection updated and shuffled -- the multiply/divide+shift problem is lethal enough that if not worked around it makes the kernel crash in time_init() because of a division by zero; the daddiu erratum might also trigger early potentially, though I have not observed it. On the other hand the daddi detection code requires the exception subsystem to have been initialised (and is there mainly for information). 4. r4k_daddiu_bug() added so that the existence of the erratum can be queried by code at the run time as necessary; useful for generated code like TLB fault and copy/clear page handlers. 5. __udelay() updated as it uses multiplication in inline assembly. Note that -mdaddi requires modified toolchain (which has been maintained by myself and available from my site for ~4years now -- versions covered are GCC 2.95.4 - 4.1.2 and binutils from 2.13 onwards). The -mfix-r4000 and -mfix-r4400 have been standard for a while though. Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

* [MIPS] Don't abort the build process if '-msym32' isn't supportedFranck Bui-Huu2007-10-11
| | | | | | | | | | | | | | -msym32 and previously the strategy to tell the compiler to generate 64-bit code but the assembler to put it into 32-bit ELF was initially a hack to get around the lack of proper 64-bit binutils support and later turned into a neat optimization with significant code size savings. But it's really just an optimization so there is nothing wrong with just dropping the option (and whatever else goes along with it, I forgot all the nasty details) on the floor if due to a vintage compiler it can't be suported.
