If anyone has any objections, please let me know. ------------------ From: Lorenzo Pieralisi [ Upstream commit 1d77e79d62cfe46ad3619d42ee0d1ebd3f0f79f4 ] An IRS is architecturally allowed to be stand-alone (ie with no direct CPU connection). Relax "cpus" and "arm,iaffids" properties constraints allowing a standalone IRS configuration.
