a3db5001e5 bsp/altera-cyclone-v: Enable FIQ for group 0 irqs 2019-02-28 11:52:35 +01:00

76918e180a bsps/arm: Add BSP_ARM_GIC_ENABLE_FIQ_FOR_GROUP_0 
The following variants

 * GICv1 with Security Extensions,
 * GICv2 without Security Extensions, or
 * within Secure processor mode

have the ability to assign group 0 or 1 to individual interrupts.  Group
0 interrupts can be configured to raise an FIQ exception.  This enables
the use of NMIs with respect to RTEMS.

BSPs can enable this feature with the BSP_ARM_GIC_ENABLE_FIQ_FOR_GROUP_0
define.  Use arm_gic_irq_set_group() to change the group of an
interrupt (default group is 1, if BSP_ARM_GIC_ENABLE_FIQ_FOR_GROUP_0 is
defined).

eec706e2bf bsps/powerpc: Fix small data area section 
Fix small data area in case no fixed size is desired.  Rename
bsp_section_set_sdata_sbss_size into bsp_section_small_data_area_size
since this symbol reflects the overall small data area size (including
space for libdl).  Do not use bsp_section_sbss_size before definition in
linker command file.  Add new symbols to <bsp/linker-symbols.h>.

Update #3687.

6c9f0176a9 libdl: Add powerpc large memory and small data support. 
- Add support for architecure sections that can be handled by the
  architecture back end.

- Add trampoline/fixup support for PowerPC. This means the PowerPC
  now supports large memory loading of applications.

- Add a bit allocator to manage small block based regions of memory.

- Add small data (sdata/sbss) support for the PowerPC. The support
  makes the linker allocated small data region of memory a global
  resource available to libdl loaded object files.

0a1f5df98e Simplify _CPU_Counter_difference() 
In order to simplify the use of CPU counter values it is beneficial to
have monotonic increasing values within the range of the CPU counter
ticks data type, e.g. 32-bit unsigned integer.  This eases the use of
CPU counter timestamps in external tools which do not know the details
of the CPU counter hardware.  The CPU counter is the fastest way to get
a time on an RTEMS system.

Such a CPU counter may be also used as the timecounter.  Use it on SPARC
for this purpose to simplify the clock drivers.

2e8b5de2b2 bsp/leon2: Move printk() support 
Avoid assert() in console_inbyte_nonblocking().

Do not poll forever in bsp_in_char().  This allows the caller to decide
what to do if no character is available.

This entangles some dependencies and fixes a spconfig02 test failure.
