* ARM: Add BSP_START_NEEDS_REGISTER_INITIALIZATIONMartin Galvan2015-02-271-0/+28
| | | | | | | | | | | | | This patch adds the macro BSP_START_NEEDS_REGISTER_INITIALIZATION and three hooks for BSP-specific register init code to arm/shared/start.S. Said hooks are bsp_start_init_registers_core (intended for initializing the ARM core registers), bsp_start_init_registers_banked_fiq (for the FIQ mode banked registers) and bsp_start_init_registers_vfp (for the FPU registers). BSP_START_NEEDS_REGISTER_INITIALIZATION would be defined in a BSP's configure.ac (so that it appears in its bspopts.h). This patch also adds the register init code required by the TMS570. We've tested it with the tms570ls3137_hdk.cfg config and it works fine.
* ARM: Support VFP-D16Martin Galvan2015-02-201-3/+5
| | | | | | | | | This patch allows the existing FPU code to support both VFP-D16 and VFP-D32. According to ARM, writes to D32DIS are ignored for D16 so there's no need to enclose the bic instruction with an #ifdef. We tested it on a TMS570LS3137 using TI initialization code and it works fine.

* arm: Add support for FPv4-SP floating point unitSebastian Huber2014-08-121-0/+15
| | | | | This floating point unit is available in Cortex-M4 processors and defined by ARMv7-M. This adds basic support for other VFP-D16 variants.

* bsps/arm: Use _ARMV4_Exception_interruptSebastian Huber2014-01-141-3/+3
| | | | | This allows read-only vector tables in ROM. It avoids also an unsolved problem with MMU/cache synchronization on SMP.
