 NetBSD/evbarm is the port of NetBSD to various evaluation and prototyping
@@ -22,6 +20,36 @@ designs.
 
 Matt Thomas is the maintainer of NetBSD/evbarm.
 
+### CPU types
+
+The evbarm port can be built with a variety of CPU options.  There are
+three main variables: the instruction set, the endianness, and whether
+there is hardware floating point.  By default the CPU type is "earm",
+and this implies little endian (el when explicitly stated), and soft
+(emulated) floating point.  Another example, suitable for Raspberry PI
+2, is earmv7hf, which is the v7 instruction set, little endian,
+and hardware floating point.
+
+Typically, various boards are best compiled with a CPU type that
+matches the board's CPU and floating point support, but generally a
+lower CPU instruction set version is workable on a newer board.  See
+build.sh and look for aliases for the evbarm port.
+
+Some processors can operate as arm or the 64-bit ARM variant, aarch64, which is supported by
+[[NetBSD/aarch64|aarch64]].
+
+### Kernels and userland
+
+The evbarm userland can be used on any system that can run code of the
+CPU type used for the build.  Typically, a particular board requires a
+kernel for that board.
+
+### anita and qemu
+
+anita can be used to test builds.  evbarm-earmv7hf uses "qemu -M
+vexpress-a15" and evbarm-aarch64 uses "qemu -M virt".  (Information on
+how to test emulated versions of other specific hardware is welcome.)
