                     17: boards based on CPUs implementing the ARM architecture. NetBSD/evbarm also
                     18: supports some specific embedded system products based on prototype board
                     19: designs.
                     20: 
1.7       mspo       21: Matt Thomas is the maintainer of NetBSD/evbarm.

1.42      gdt        23: ### CPU types
                     24: 
1.57      gdt        25: The evbarm port can be built with a variety of CPU options, corresponding to the
                     26: [large array of ARM CPU architectures](https://en.wikipedia.org/wiki/ARM_architecture#Cores).
                     27: There are
1.56      gdt        28: four main variables: the word size, the instruction set, the
                     29: endianness, and whether there is hardware floating point.  By default
                     30: the CPU type is "earm", and this implies aarch32 (32-bit), \todo cpu
                     31: architecture, little endian (el when explicitly stated), and soft
1.58      gdt        32: (Emulated) floating point.  Another example, suitable for Raspberry PI
1.56      gdt        33: 2, is earmv7hf, which is aarch32, the v7 instruction set, little
                     34: endian, and hardware floating point.
1.42      gdt        35: 
                     36: Typically, various boards are best compiled with a CPU type that
                     37: matches the board's CPU and floating point support, but generally a
                     38: lower CPU instruction set version is workable on a newer board.  See
                     39: build.sh and look for aliases for the evbarm port.
                     40: 
1.56      gdt        41: Through NetBSD 8, the evbarm port has supported exclusively the
                     42: aarch32 (32-bit CPU) sub-family of the ARM architecture.  Some
                     43: processors, such as many supporting the armv8 CPU architecture, also
                     44: support a 64-bit instruction set, referred to as aarch64.  This is
                     45: sometimes referred to as a distinct port, [[NetBSD/aarch64|aarch64]],
                     46: with code in src/sys/arch/aarch64, but it is built as the evbarm port
                     47: with aarch64 cpu type, and available as the alias evbarm64.
1.50      gdt        48: 
1.58      gdt        49: Note that MACHINE_ARCH=aarch64 currently refers to the A64 instruction
                     50: set and the aarch64 architecture, built for the armv8 architecture.
                     51: (Note also that armv8 is the first architecture to support aarch64, so
                     52: this will not be an issue until at least armv9.)
                     53: 
                     54: #### ABI types
                     55: 
                     56: There are two basic ABIs on ARM.  One, called oabi, assumed a
                     57: particular kind of hardware floating point (FPA).  This results in
                     58: faulting any floating-point instructions for kernel emulation on a
                     59: vast number of CPus, which is very slow.  A newer one, called eabi,
                     60: has two variants.  Both have stricter alignment rules, tending to 8
                     61: byte rather than 4 bytes for 8-byte types (but actually read the specs
                     62: if you care).  The one without "hf" emulates floating point without
                     63: causing traps/emulation, and "hf" uses VFP instructions, which are
                     64: present on modern CPUs. See the
                     65: [TS-7200](https://wiki.embeddedarm.com/wiki/EABI_vs_OABI) and
                     66: [Debian](https://wiki.debian.org/ArmEabiPort) documentation.
                     67: 
                     68: Now, EABI is normal, and OABI is crufty.  The only real reason NetBSD
                     69: retains OABI support is binary compatibility with older releases.  The
                     70: "arm" and "armeb" MACHINE_ARCH targets are OABI; the rest of the
                     71: targets, all having "earm" are EABI.
                     72: 
                     73: \todo CHECK THIS: The "aarch64" MACHINE_ARCH target is an EABI variant.
