From ce1feaa7322affd3b979c9fe93dd8f7462ea9eca Mon Sep 17 00:00:00 2001 From: David Brownell Date: Sun, 21 Feb 2010 14:28:53 -0800 Subject: ARMv7-M: start using "struct arm" This sets up a few of the core "struct arm" data structures so they can be used with ARMv7-M cores. Specifically, it: - defines new ARM core_modes to match the microcontroller modes (e.g. HANDLER not IRQ, and two types of thread mode); - Establishes a new microcontroller "core_type", which can be used to make sure v7-M (and v6-M) cores are handled right; - adds "struct arm" to "struct armv7m" and arranges for the target_to_armv7m() converter to use it; - sets up the arm.core_cache and arm.cpsr values - makes the Cortex-M3 code maintain arm.map and arm.core_mode. This is currently set up as a parallel data structure, primarily to minimize special cases for the semihosting support with microcontroller profile cores. Later patches can rip out the duplicative ARMv7-M support and start reusing core ARM code.
