Fixes: 8a863c8120994981a099 Reviewed-by: Peter Maydell <peter.maydell@linaro.org> if you tweak the commit message to mention that it wasn't a user-visible bug (but I'll do that myself if there isn't anything else in the series that means it needs a respin). thanks -- PMM

It is worth fixing if we continue the MachineClass code cleanup Igor wants (moving the ram size / cpu type checks in the machine common code). > > Fixes: 8a863c8120994981a099 > > Reviewed-by: Peter Maydell <peter.maydell@linaro.org> > if you tweak the commit message to mention that it > wasn't a user-visible bug (but I'll do that myself if there > isn't anything else in the series that means it needs a respin). > > thanks > -- PMM >

The Cubieboard is a singleboard computer with an Allwinner A10 System-on-Chip [1]. As documented in the Allwinner A10 User Manual V1.5 [2], the SoC has an ARM Cortex-A8 processor. Currently the Cubieboard machine definition specifies the ARM Cortex-A9 in its description and as the default CPU. This patch corrects the Cubieboard machine definition to use the ARM Cortex-A8.
