Subject: [RFC PATCH for Juno 0/2] Drivers for Juno to boot from ACPI

This patch set is example of the sort of driver changes needed to boot
Juno using ACPI tables, which using the ACPI tables devloped for MS
Windows and published by ARM [1].

For the smsc911x driver, it is based on the following ASL fragment
which is part of DSDT for Juno:

    // LAN9118 Ethernet
    Device(ETH0) {
      Name(_HID, "ARMH9118")
      Name(_UID, Zero)
      Name(_CRS, ResourceTemplate() {
              Memory32Fixed(ReadWrite, 0x1A000000, 0x1000)
              Interrupt(ResourceConsumer, Level, ActiveHigh, Exclusive) { 192 }

UART driver is just for review purpose, ARM is working on a more
functional UART driver that does not poll to transmit. But it shows
how to initialise SBSA compatible UART without clock definitions in

You also can refer to the boot log from [2].
