We should stop when we find the first AG with a maximum possible allocation size. This causes excessive CPU ...

Problem Details: Commit 5d190c40100793a6dfc37bf325677c10f3c80edf (omap2+: Initialize omap_irq_base for entry-macro.S from platform code) simplified the handling of omap_irq_base for multi-omap builds.
