This imports the full xil_exception.h instead of an empty stub. This is
required for some Xilinx drivers. The imported files adhere to the
current VERSION file.
This makes xil/sleep.h a stub to prevent multiple differing definitions
of sleep functions from toolchain and local headers. The non-standard
sleep definitions were not in use and can be added later if needed.
Xilinx's upstream ILP32 xil_cache.h header is out of date and broken.
This provides a copy of the LP64 header in place of the ILP32 header
since the LP64 header includes all the correct types to work with either
data model.
This support code is necessary for many Xilinx-provided bare metal device
drivers supported on ARM, AArch64, and MicroBlaze platforms. Support for
all of these architectures is kept under bsps/include due to multiple
architecture variants being supported which requires complex logic in
the build system. The imported files are and should be able to remain
unmodified. Import information is kept in bsps/shared/xil/VERSION.
