arch, linux, package: remove whitespaces

2017-03-29T21:30:37+00:00

Whitespaces were searched using the following regex: [ ]{1,}\t and then manually removed in most of the cases. For xserver_xorg-server.mk, tabs before backslashes were removed. Signed-off-by: Bernd Kuhls Signed-off-by: Thomas Petazzoni

arch/xtensa: add definitions for the Xtensa overlay

2017-03-26T13:49:12+00:00

Currently, we have four packages that need to use the Xtensa overlay: binutils, gcc-initial, gcc-final and gdb. However, they all use three different ways to check for, and use the overlay. Furthermore, two of them define the same variable: XTENSA_CORE_NAME is defined both by binutils and gdb In order to sanitise that, have the Xtensa architecture export the appropriate variables: the name of the core and the path to the overlay tarball. Packages can then check and use those variables. Signed-off-by: "Yann E. MORIN" Cc: Thomas Petazzoni Signed-off-by: Max Filippov Signed-off-by: Thomas Petazzoni

arch/Config.in.arc: fix BR2_READELF_ARCH_NAME

2017-03-22T21:05:54+00:00

On ARC, depending on the CPU selected, the ELF machine number might be different. Take this into account when defining BR2_READELF_ARCH_NAME. Fixes: http://autobuild.buildroot.net/results/0a1957056e07cedc4839439c0ea8ebd1f646b904/ Signed-off-by: Thomas Petazzoni

arch: add BR2_READELF_ARCH_NAME hidden config option

2017-03-20T21:22:17+00:00

This config option corresponds to the string returned by readelf for the "Machine" field of the ELF header. It will be used to check if the architecture of binaries built by Buildroot match the target architecture. Signed-off-by: Thomas Petazzoni

arch: add support for the csky architecture

2017-03-04T13:35:55+00:00

This commit provides basic support for the C-SKY architecture. Signed-off-by: Guo Ren [Thomas: minor tweaks.] Signed-off-by: Thomas Petazzoni

arch: add OpenRISC architecture support

2017-01-25T21:53:53+00:00

Add support for OpenRISC. See here for more details about OpenRISC http://openrisc.io. All buildroot included upstream binutils versions are supported. Gcc support is not upstream, to be able to enable musl C library support later, we use the branch with musl support. At the moment it is possible to build a musl based toolchain, but bootup in Qemu fails. Gdb is only working to debug bare-metal code, there is no support for gdbserver/gdb on Linux, yet.

arch/Config.in.arm: support thumb2 instructions for ARMv8 in 32bit mode

2016-12-08T21:32:17+00:00

The ARMv8 cores all support thumb2 instructions when running in aarch32 mode. Signed-off-by: Peter Korsgaard Signed-off-by: Thomas Petazzoni

arch/Config.in.arm: only enable BR2_ARM_CPU_HAS_NEON for ARMv8 in 32bit mode

2016-12-08T21:32:16+00:00

A number of packages use BR2_ARM_CPU_HAS_NEON to know if the target handles aarch32 neon instructions, which is only true for ARMv8 cores when they are running in 32bit mode. Notice: These cores do support neon-like instructions using a different encoding in 64bit mode (it is a required part of ARMv8, similar to the FPU).

arch/Config.in.arm: only enable BR2_ARM_CPU_HAS_ARM for ARMv8 in 32bit mode

2016-12-08T21:32:14+00:00

Fixes: http://autobuild.buildroot.net/results/5e6/5e67cc067a06f7364cde1a8393ea72608fe7fef1/ A number of packages use BR2_ARM_CPU_HAS_ARM to know if the target handles classic A32 instructions, which is only true for ARMv8 cores when they are running in 32bit mode.
