Subject: [PATCH v7 09/13] ARM: introduce ARM_SINGLE_ARMV7M for ARMv7-M platforms
Date: Sat, 16 May 2015 11:44:21 +0200 [thread overview]
Message-ID: <1431769465-26867-10-git-send-email-stefan@agner.ch> (raw)
In-Reply-To: <1431769465-26867-1-git-send-email-stefan@agner.ch>
This introduces a new top level config symbol ARM_SINGLE_ARMV7M
for non-MMU, ARMv7-M platforms. It also support multiple ARMv7-M
platforms in one kernel image since the cores share the same
basic memory layout and interrupt controller. However, this works
only if the combined platforms also have a similar (main) memory
layout.
