Hi Jerome

Yes, ACPI table is often filled with different optional components so
that it can be compatible with several platform variants without impact
on the ACPI data. Then, components are enabled/disabled depending board ID.

This BCM2E3C is disabled on your platform, but seems compatible with 
hci_bcm UART driver (2GPIOs + 1IRQ). Should be only a revision of BCM2Ex.
Broadcom input is welcome here.

Loic
