The current early-printk support for ARM is rather hard-coded, making it hard to add machines or tweak settings. This series slightly moves some code to gather UART settings in xen/arch/arm/Rules.mk instead of the actual .c files. Also it allows two different machines with different settings to share the same driver, which the last patch exploits to add support the Calxeda Midway hardware. This

These series patch enable Allwinner A31(code name sun6i) support in assemble. with these patches, the cpu 0 of sun6i SOC could successful boot into the c environment. Bamvor Jian Zhang (4): xen/arm: introduce Cortex-A7 support xen/arm: introduce Allwinner sun6i SOC basic support xen/arm: enable early printk for sun6i xen/arm: enable switch to hyper mode for sun6i xen/arch/arm/Rules.mk

Since OMAP UART has a few distinct features than common 8250 UART, I re-implemented its driver rather than porting it based on ns16550.c. There are mainly two big differences between the implementations. First, OMAP UART introduces the concept of register access mode, which divides the register map into seperated space. Switching the access mode is then necessary when configuring it. Second, THRE

I''m afraid this series is rather a grab bag and it is distressingly large at this stage. With this series I can boot an Xgene board until it fails to find its SATA controller. This is a dom0 issue for which patches are pending from APM (/me nudges Anup). As well as the APM specific platform stuff there are also some generic improvements which were either necessary or useful during this
