FreeBSD developers are still working on bringing up ARM hardware support for various platforms so that it's in a similar state to Linux.
Following the recent Phoronix news articles about an easy way to try out FreeBSD 10 in its current development state along with Clang becoming the default compiler, there's been questions raised by Phoronix readers about the FreeBSD ARM support. Simply put, at the moment it's not in as good of shape as it is for Linux. ARM is considered a "Tier 2" architecture of FreeBSAD with no official releases or pre-built packages being made by the project.
While the Linux kernel now has mainline ARMv8 AArch64 64-bit support and Xen Cortex-A15 support among other modern ARM hardware features, FreeBSD is still working out support for older ARM platforms.
