From: Kyle Evans <kev...@freebsd.org>
While the nearly-universal default for the Raspberry Pi family is to use
spin tables and the spin table implementation provided by the Raspberry Pi
Foundation, FreeBSD and others may use a PSCI implementation instead.
Accommodate these setups by allowing them to configure for more than one
page to be reserved in the initial reservation. The default reservation
remains as one page.
