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.
