Subject: [Qemu-devel] [PATCH 0/2] Fix compilation dependency issues of CONFIG_ARM_V7M
Date: Thu, 27 Apr 2017 12:38:45 -0500	[thread overview]
Message-ID: <1493314727-6951-1-git-send-email-wei@redhat.com> (raw)

CONFIG_ARM_V7M is used to control the compilation of NVIC and SysTick
Timer in QEMU. These two devices are not available when CONFIG_ARM_V7M
is un-defined. This can cause problems with ARMv7M code as it is tightly
integrated with NVIC for processing IRQ and exception.

This patchset addresses the problem by introducing stub functions when
CONFIG_ARM_V7M is not defined. It also makes the compilation of several
existing v7M-profile SoCs depedent on CONFIG_ARM_V7M.

Thanks,
-Wei
