*	zynqmp: Add support for the CFC-400X	Kinsey Moore	2022-11-09	1	-0/+4
\| \| \| \| \| \| \| \|	This adds a BSP variant for the ZynqMP BSP family to support the Innoflight CFC-400X platform. To properly support the CFC-400X, device trees were added to the ZynqMP platform due to both the optional management interface as well as alternate physical configuration of the ethernet interfaces.
*	aarch64: Break out MMU definitions	Kinsey Moore	2021-11-01	1	-0/+1
\| \| \| \| \| \|	This moves the AArch64 MMU memory type definitions into cpukit for use by libdebugger since remapping of memory is required to insert software breakpoints.
*	cpukit: Add AArch64 SMP Support	Kinsey Moore	2021-09-21	1	-8/+20
\| \| \| \|	This adds SMP support for AArch64 in cpukit and for the ZynqMP BSPs.
*	bsps/aarch64: Add MMU driver to relax alignment	Kinsey Moore	2021-05-27	1	-0/+77
	Currently, the AArch64 BSPs have a hard time running on real hardware without building the toolchain and the bsps with -mstrict-align in multiple places. Configuring the MMU on these chips allows for unaligned memory accesses for non-device memory which avoids requiring strict alignment in the toolchain and in the BSPs themselves. In writing this driver, it was found that the synchronous exception handling code needed to be rewritten since it relied on clearing SCTLR_EL1 to avoid thread stack misalignments in RTEMS_DEBUG mode. This is now avoided by exactly preserving thread mode stack and flags and the new implementation is compatible with the draft information provided on the mailing list covering the Exception Management API.
