[PATCH 00/12] aspeed: fixes and extensions

["Cédric Le Goater" <clg@kaod.org>]

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 "uart" machine option to
let the user define the default UART device of the machine from the
QEMU command line :

    -M ast2500-evb,uart=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.
