Author: manu Date: Wed Aug 7 13:13:16 2019 New Revision: 350674 URL: https://svnweb.freebsd.org/changeset/base/350674 Log: ofw: ofw_reg_to_paddr: Use a 256 static array for the cell Some hardware needs more than 32, bump this value. We cannot use the _alloc for of getencprop as this function is called too early in the boot before pmap is initialized and we only have 2k of stack when cninit is called.
