SAMA5D3/4: All configurations. I suspect a MMC/SD multi-block DMA transfer issue. So for name, this feature is disabled in all configurations

Also, CONFIG_MMCSD_MULTIBLOCK_DISABLE=y is set to disable multi-block

Both of these issues need to be revisited to determine there is or
is not a real 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.

5) I believe that there is an issue when the internal AT25 FLASH is
formatted by NuttX. That format works fine with Linux, but does not
appear to work with Windows. Reformatting on Windows can resolve this.

2) HSCMI TX DMA support is currently commented out. There were problems at
one time (on the SAMA5D3) and the temporary workaround was simpley to
one time (on the SAMA5D3) and the temporary workaround was simply to
disable TX DMA. There have been several fixes to both HSMCI and DMA
support since then and TX DMA is very likely okay now. But this needs
to be verified by re-enabled HSMCI TX DMA.
Also, CONFIG_MMCSD_MULTIBLOCK_DISABLE=y is set to disable multi-block
transfers.
3) There is a kludge in place in the Ethernet code to work around a problem
that I see. The problem that I see is as follows:
