[Qemu-devel] [PATCH v4 0/4] Add ASPEED AST2400 SoC and OpenPower BMC machine

[Andrew Jeffery <andrew@aj.id.au>]

This patch series models enough of the ASPEED AST2400 ARM9 SoC[0] to boot an
aspeed_defconfig Linux kernel[1][2]. Specifically, the series implements the
ASPEED timer and VIC devices, integrates them into an AST2400 SoC and exposes
it all through a new opbmc2400 machine. The device model patches only partially
implement the hardware features of the timer and VIC, again mostly just enough
to boot Linux.

Unfortunately the datasheet describing the devices is not generally available,
but I'll try to add comments to any unclear areas.

The addition of the AST2400 to QEMU is motivated by use of the SoC as a BMC in
OpenPOWER[2][3] machines and the ongoing development of OpenBMC[4]. The
presence of a machine model utilising the AST2400 will help with development
and testing of the OpenBMC stack.

Cheers,

Andrew

Changes since v3:

  Address comments from Peter Maydell, splitting the machine model from
  hw/arm/ast2400.c into hw/arm/opbmc2400.c amongst other minor cleanups to the
  timer and VIC.

Changes since v2:

  This re-roll is a reasonable rework of the patches in the series, which may
  make it difficult to compare v1 to v2.
