Need to retest. That change is necessary, but may not be sufficient to
solve the problem.
3) GMAC has only been tested on a 10/100Base-T network. I don't have a
1000Base-T network to support additional testing.

Open Issues
===========
The BASIC nsh configuration is fully function (as desribed below under
"Configurations"). There are still open issues that need to be resolved:
1. SDRAM support has been implemented and tested using the nsh
configuration (as desribed below). Currently the memory test does not
pass. I am suspecting that this is because D-Cache is enabled when
SDRAM is configured?
2. HSCMI. CONFIG_MMCSD_MULTIBLOCK_DISABLE=y is set to disable multi-block
transfers only because I have not yet had a chance to verify this. The
is very low priority to me but might be important to you if you are need
very high performance SD card accesses.
3. HSMCI TX DMA is currently does not work.
4. There not yet any support for the following: QSPI, USB, EMAC, AT24, or
WM8904. So there is still plenty to be done.
Serial Console
