I'm currently testing Linux booting from mainline U-Boot (full version with DDR training integrated as SPL - no bin_hdr) on the Marvell Armada XP Development Board DB-MV784MP-GP. And this results in (at least) those 2 problems: a) Secondary CPU(s) fail to come online: ... [ 0.130692] CPU: Testing write buffer coherency: ok [ 0.135785] CPU0: thread -1, cpu 0, socket 0, mpidr 80000000 [ 0.141892] Setting up static identity map for 0x82c0 - 0x8318 [ 0.148013] mvebu-soc-id: MVEBU SoC ID=0x7846, Rev=0x2 [ 0.153357] mvebu-pmsu: Initializing Power Management Service Unit [ 0.160323] Booting CPU 1 [ 1.158867] CPU1: failed to come online [ 1.162960] Booting CPU 2 [ 2.158866] CPU2: failed to come online [ 2.162954] Booting CPU 3 [ 3.158865] CPU3: failed to come online [ 3.162810] Brought up 1 CPUs [ 3.165870] SMP: Total of 1 processors activated (1594.16 BogoMIPS).

Please find the complete boot log attached. Any ideas why those problems might occur with mainline U-Boot? Most likely some register setup is missing that is usually done in bin_hdr. Where could I check / test for this CPU online problem? Thanks, Stefan -------------- next part -------------- A non-text attachment was scrubbed...
