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 palmetto-bmc 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.

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.
