commit 786bdc3b8ef98a1bf99dff650e37ed69c7f0575f
Author: Sean Anderson <sean.ander...@seco.com>
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.
