[ARM] MV78xx0: Support for Buffalo WXL (Terastation Duo)
* Modification of Kconfig to add the Option * 1 new file : buffalo-wxl-setup.c This file is inspired from the db-78xx0-setup.c already present. The following is done: - Configure MPP Lines for the plateform (see my patch for MPP) This is taken from the stock kernel provided by buffalotech (the vendor) - GigaBit Ethernet - Sata - Uart are initiallized in a different way than on the dev board as we have one core only. - USB The kernel has been running for some days now on my plateform.
