X-Received-From: 2001:8b0:1d0::2 Subject: [Qemu-devel] [PATCH 2/2] hw/arm/armv7m: Remove unused armv7m_init() function X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Jim Mussared , =?utf-8?q?Steffen_G=C3=B6rtz?= , patches@linaro.org, Joel Stanley , Stefan Hajnoczi , Julia Suvorova Errors-To: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Sender: "Qemu-devel" Remove the now-unused armv7m_init() function. This was a legacy from before we properly QOMified ARMv7M, and it has some flaws: * it combines work that needs to be done by an SoC object (creating and initializing the TYPE_ARMV7M object) with work that needs to be done by the board model (setting the system up to load the ELF file specified with -kernel) * TYPE_ARMV7M creation failure is fatal, but an SoC object wants to arrange to propagate the failure outward * it uses allocate-and-create via qdev_create() whereas the current preferred style for SoC objects is to do creation in-place Board and SoC models can instead do the two jobs this function was doing themselves, in the right places and with whatever their preferred style/error handling is.
