[U-Boot] [PATCH v4 00/13] Support for the Faraday ftgmac100 controller

[Cédric Le Goater]

Hello,

This series re-enables the Faraday ftgmac100 controller driver and its
Aspeed variant as as one can find on the OpenPOWER platforms. The
driver is largely reworked to support the driver model and also adds
the MDIO bus and phylib support. It was tested on the AST2500 evb.

Thanks,

C.

Changes since v3 :

 It didn't seem necessary to remove the 'dev' argument from the
 ftgmac100_phy_init() and ftgmac100_phy_reset() function prototypes as
 the code is completely reworked in patch 5.

 - improved ftgmac100_mdio_init() and ftgmac100_phy_init() prototypes
 - introduced a ftgmac100_wait_for_txdone() function similar to the
   wait_for_bit_*() macros.

Changes since v2 :

 - split changes in multiple patches to preserve git history, but the
   code has not changed since the reviewed v2 patchset.
 - included a couple more changes to sync the DTS file with Linux.

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
