foundation model no longer boots with boot-wrapper

[Al Stone]

Using the instructions in the wiki that worked a coupld of weeks ago:

    https://wiki.linaro.org/LEG/Engineering/Kernel/ACPI/AcpiOnFoundation

I build a kernel, DTB and ACPI blob and the kernel now hangs during boot:

So what broke? CPU enumeration? This should be recreatable with the acpi working branch (not the leg-kernel), using the boot wrapper, the Linaro 4.8 toolchain, and the attached config file.

Yes, It seems some thing wrong with the CPU enumeration:

psci: probing function IDs from device-tree
ACPI: Local APIC address 0x2c002000
ACPI: GIC (acpi_id[0x0000] gic_id[0x0000] enabled)

ACPI: GIC (acpi_id[0x0007] gic_id[0x0007] disabled)
8 CPUs available, 16 CPUs total

I saw PSCI is enabled, maybe the config is different from I uased, I will check the config attached.

And I saw that "8 CPUs available, 16 CPUs total", in foundation model, only 4 cpus available, are you sure it is foundation model?

Yup, absolutely sure it is the Foundation model. My config
could be wrong, too, so if you see something to change, let
me know.
