228 * Macros for various sorts of alignment and rounding. The "align" must
233 * return x rounded down to an align boundary
234 * eg, P2ALIGN(1200, 1024) == 1024 (1*align)
235 * eg, P2ALIGN(1024, 1024) == 1024 (1*align)

271 * return x rounded up to the next phase (offset) within align.
272 * phase should be < align.
