[PATCH 02/26] MIPS: PCI: Make pcibios_set_cache_line_size an initcall

From: Paul Burton
Date: Fri Aug 26 2016 - 11:38:49 EST


In preparation for allowing configurations in which pcibios_init is not
included, make pcibios_set_cache_line_size an initcall. arch_initcall is
used such that it runs before the pcibios_init subsys_initcall for
platforms that continue to use it.
