    board: Add LS1046ARDB
    
    This adds support for the LS1046A Reference Design Board. There are
    several JTAG headers accessable once the case is opened, but this config
    is for the externally-accessable CMSIS DAP.

commit 5b70c1f679755677c925b4e6dd2c3d8be4715717

    target: Add LS1046A
    
    The LS1046A is a quad-core processor from NXP in the layerscape family.
    This SoC is a bit tricky to program: while the AArch64 CPUs are
    little-endian, most of the peripherals are big-endian. Care must be
    taken when interpreting memory reads/writes. This processor is in the
    same family as the ls1012a, so the setup is similar.
    
    If you use OpenOCD to attach early in the boot process, only the cpu0
    may be available. Trying to halt other CPUs will fail. To avoid this,
    defer examination of cpus 1-3, and provide a core_up helper (like e.g.
    zynqmp).
