[Qemu-arm] [PATCH v3 0/3] Add ASPEED AST2400 machine model

[Andrew Jeffery]

This patch series models enough of the ASPEED AST2400 ARM9 SoC[0] to boot an
aspeed_defconfig Linux kernel[1]. Specifically, the series implements the timer
and VIC devices and integrates them into a new ast2400 machine through a
AST2400SOC model. 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 for the AST2400 will help with development and
testing of the OpenBMC stack.

Cheers,

Andrew

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.
