Subject: [PATCH v7 10/13] ARM: efm32: use ARM_SINGLE_ARMV7M
Date: Sat, 16 May 2015 11:44:22 +0200 [thread overview]
Message-ID: <1431769465-26867-11-git-send-email-stefan@agner.ch> (raw)
In-Reply-To: <1431769465-26867-1-git-send-email-stefan@agner.ch>
Use the new config symbol ARM_SINGLE_ARMV7M which groups config
symbols used by modern ARMv7-M platforms. It also support multiple
ARMv7-M platforms in one kernel image. However, this only works if
the combined platforms share the same (main) memory layout.
Also use generic debug/uncompress.h for all ARMv7-M platforms.
