[v2,00/12] aspeed: fixes and extensions

Hello,

This series fixes issues spotted by Coverity and adds a couple of
improvements for the machine definition.

The first is to offer the capability to define all CS of all SPI
controllers without introducing new machine types, using a blockdev on
the command line :

    -blockdev node-name=fmc0,driver=file,filename=./flash.img
    -device mx66u51235f,addr=0x0,bus=ssi.0,drive=fmc0

instead of using drives which relies on the command line order.
Ultimately, we will get rid of drive_get(IF_MTD, ...) but we are not
there yet. For this, SSIPeripheral is extended with an "addr"
property.

A second extension is the introduction of a "bmc-console" machine
option to let the user define the default UART device of the machine
from the QEMU command line :

    -M ast2500-evb,bmc-console=uart3

Last, a new "vfp-d32" CPU property is added to ARM CPUs to model FPUs
implementing VFPv4 without NEON support and with 16 64-bit FPU
registers (and not 32 registers). This is the case for the Cortex A7
of the Aspeed AST2600 SoC. I hope I got it right this time.

Thanks,

C.

Changes in v2:

  - changed "addr" property to a uint8_t
  - renamed "uart" machine option to "bmc-console" 

Cédric Le Goater (12):
  aspeed/hace: Initialize g_autofree pointer
  aspeed: Introduce a boot_rom region at the machine level
  aspeed: Use the boot_rom region of the fby35 machine
  hw/ssi: Add an "addr" property to SSIPeripheral
  hw/ssi: Introduce a ssi_get_cs() helper
  aspeed/smc: Wire CS lines at reset
  hw/ssi: Check for duplicate addresses
  aspeed: Create flash devices only when defaults are enabled
  m25p80: Introduce an helper to retrieve the BlockBackend of a device
  aspeed: Get the BlockBackend of FMC0 from the flash device
  aspeed: Introduce a "bmc-console" machine option
  target/arm: Allow users to set the number of VFP registers
