[U-Boot] [PATCH v2 0/7] Support for the Faraday ftgmac100 controller

[Cédric Le Goater]

Hello,

This series re-adds a driver for the Faraday ftgmac100 controller and
its Aspeed variant as as one can find on the OpenPOWER platforms.
I have choosen to remove and re-add the driver to ease review of the
changes, which are numerous, but we can proceed differently if you
prefer.

It was tested on the AST2500 evb.

Thanks,

C.

Changes since v1 :

 - improved comments in the code
 - changed the type of 'iobase' to 'struct ftgmac100 *' to remove the
   casts in other routines.
 - replaced the loop in the mdio methods by a call to readl_poll_timeout()
   and fixed the returned value.
 - added a flush cache on the arrays of TX and RX descriptors in
   ftgmac100_start()
 - fixed returned value of 
 - added a timer loop to catch transmit timeouts
 - introduced a clk_bulk
 - improved Kconfig description
 - introduced a udevice_id .data model
 - dropped is_aspeed bool
 - dropped MDIO interface setting for Aspeed SoC. The default is
   correct.
 - removed the clcoks which are now handled automatically in the
   ftgmac100 driver
 - introduced a fix for the D2-PLL clock setting
