Add a System Level Control Register driver for the Xilinx Zynq
Ultrascale+ MPSoC with basic clock control functionality for use with
the Cadence GEM. This also removes the Zynq-7000 clock control weakref
from compilation depending on the BSP in use.
Similar to the UARTs, ZynqMP hardware platforms use the highest
memory-mapped CGEM peripheral as the primary instance of that
peripheral. This change allows operation on hardware as well as QEMU.
Alignment on 64bit hardware is strict in comparison to running in an
emulator. This resolves an alignment exception when allocating memory on
real hardware.
At least the powerpc C++ compiler defines currently _GNU_SOURCE due to a GCC
configuration error. This leads to conflicting qsort_r() definitions.
As a workaround undefine _GNU_SOURCE for this C++ compatibility test file.
Update #4078.
In serporidok use the same structures used to hand over to the XDR
encode/decode routines. We must not mix packed and unpacked structures.
Update #4025.
Some targets support only flushing or invalidating complete cache lines.
In this cases misaligned buffers might lead to unexpected results. This
patch adds a flag that allows drivers to signal to the bus dma driver
that it is OK to round a buffer to the next full cache line. That's for
example necessary if a driver wants to send out 14 byte via a USB DMA.
Only the driver knows whether these 14 bytes are located in an otherwise
unused cache line aligned buffer.
There is a bug in the #ifdef regarding FDT so this file hasn't been
compiled. If that bug is solved, the driver doesn't work for some other
reason.
With the FDT-bug the driver hasn't been used by anyone. So just remove
it again.
- Update imported files to compile rtems-libbsd for i386 based BSPs
- Mostly commenting out parts which create compile or link errors in
RTEMS, but aren't needed
- The files in the i386 directory have been moved to common x86 directories by FreeBSD:
- freebsd/sys/x86/x86/legacy.c
- freebsd/sys/x86/include/machine/legacyvar.h
- freebsd/sys/x86/include/machine/specialreg.h
- Add header files in rtemsbsd directory to direct compiler to new files
