* bsps/arm: Export bsp_start_hook_0_done symbol from ARM start.S.Pavel Pisa2016-10-021-0/+1
| | | | | | | | The symbol can be used by bsp_start_hook_0 when complete RAM memory is initialization and overwritten during BSP self-test. The test overwrites even memory used to store return address / link register and regular resturn from bsp_start_hook_0 is not possible then.
* bsps/arm: Support recent bootloaders starting kernel in HYP modePavel Pisa2016-10-021-4/+75
| | | | | | | | | | | | | | | | | | | | | When HYP mode is detected at startup then setup HYP mode vectors table (for future extensions) clean exceptions switching to HYP mode and switch CPU to ARM SVC mode. BSPs which want to use this support need to include next option in their configure.ac RTEMS_BSPOPTS_SET([BSP_START_IN_HYP_SUPPORT],[*],[1]) RTEMS_BSPOPTS_HELP([BSP_START_IN_HYP_SUPPORT], [Support start of BSP in ARM HYP mode]) AM_CONDITIONAL(BSP_START_IN_HYP_SUPPORT,test "$BSP_START_IN_HYP_SUPPORT" = "1") and need to include next lines in corresponding Makefile.am if BSP_START_IN_HYP_SUPPORT libbsp_a_SOURCES += ../shared/startup/bsp-start-in-hyp-support.S endif Updates #2783
* 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.
