Sean Anderson	db30c5f8ba	mdio_regs: Add register to enable test modes This adds a register allowing us to control the test modes of the descrambler and link monitor. Signed-off-by: Sean Anderson <seanga2@gmail.com>	2022-11-02 17:44:37 -04:00
Sean Anderson	7d35e07401	mdio_regs: Add support for counters This adds support for counters for interesting conditions (disconnects, PMD phase wraparounds, errors, etc). All the counters are 15 bits instead of 16, because 16-bit counters have an fmax of 110MHz or so. All the counters live behind a condition because they ~double the number of resources used.

Sean Anderson	3ec1f4d77d	Automatically dump signals While manually dumping signals with a macro works OK for standalone modules, it doesn't work when multiple modules are included. Instead, create a second top-level module to dump signals. Inspired (once again) by [1].

Sean Anderson	d9602b6f78	Add MII management functions This adds a module implementing the the MII management functions (the MDIO regs). For the moment, we just implement the standard registers. Signed-off-by: Sean Anderson <seanga2@gmail.com>	2022-08-31 12:36:11 -04:00
