commit 3fcfe4f196f6c333ee0ba2078af9cfa3eb896761
Author: Sean Anderson <sea...@se...>
Date:   Fri Feb 11 17:45:32 2022 -0500

    target: Add support for ls1088a
    
    The LS1088A is an octo-core aarch64 processor from NXP in the layerscape
    family. The JTAG is undocumented, but I was able to figure things out
    from the output of `dap info`. This is the first in-tree example of
    using the hwthread rtos (as far as I know), so hopefully it can serve as
    an example to other developers. There are some ETMs, but I was unable to
    try them out because I got 'invalid command name "etm"' when trying to
    test things out.

    cpld: altera-epm240: Increase adapter speed
    
    According to the datasheet, the minimum clock period with Vccio1 = 1.5V
    (the lowest voltage supported) is 143ns, or around 6MHz. Set the default
    adapter speed to 5 MHz.
