Add endianness support to cap_mkdb(1), useful for cross builds. 2005-02-22 23:29:54 +00:00			`# $FreeBSD$`

Start to import support for the AArch64 architecture from ARM. This change only adds support for kernel-toolchain, however it is expected further changes to add kernel and userland support will be committed as they are reviewed. As our copy of binutils is too old the devel/aarch64-binutils port needs to be installed to pull in a linker. To build either TARGET needs to be set to arm64, or TARGET_ARCH set to aarch64. The latter is set so uname -p will return aarch64 as existing third party software expects this.

Clean up detection of big-endian ARM. In all cases we follow the pattern armeb. Check we are building for arm and if MACHINE_ARCH follows this pattern. 2014-10-01 16:00:21 +00:00			`(${MACHINE} == "arm" && ${MACHINE_ARCH:Marmeb} == "") \|\| \`
Start support for the RISC-V 64-bit architecture developed by UC Berkeley. RISC-V is a new ISA designed to support computer research and education, and is now become a standard open architecture for industry implementations. This is a minimal set of changes required to run 'make kernel-toolchain' using external (GNU) toolchain. The FreeBSD/RISC-V project home: https://wiki.freebsd.org/riscv.

Retire TARGET_ABI. Implement MACHINE_ARCH=mips64e[lb] to build N64 images. This replaces MACHINE_ARCH=mipse[lb] TARGET_ABI=n64. MACHINE_ARCH=mipsn32e[lb] has been added, but currently requires WITHOUT_CDDL due to atomic issues in libzfs. I've not investigated this much, but implemented this to preserve as much of the TARGET_ABI functionality that I could. Since its presence doesn't affect the working cases, I've kept it in for now. Added mips64e[lb] to make universe, so more kernels build. And I think this (finally) closes the curtain on the tbemd tree. 2011-01-07 20:26:33 +00:00			`${MACHINE_ARCH:Mmips*el} != ""`

Assume a big-endian default on MIPS and drop the "eb" suffix from MACHINE_ARCH. This makes our naming scheme more closely match other systems and the expectations of much third-party software. MIPS builds which are little-endian should require and exhibit no changes. Big-endian TARGET_ARCHes must be changed: From: To: mipseb mips mipsn32eb mipsn32 mips64eb mips64 An entry has been added to UPDATING and some foot-shooting protection (complete with warnings which should become errors in the near future) to the top-level base system Makefile. 2012-03-29 02:54:35 +00:00			`${MACHINE_ARCH:Mmips*} != ""`
