[PATCH v3 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.

Git tree available here:

  https://github.com/legoater/u-boot/commits/aspeed

Thanks,

C.

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

[PATCH v3 03/13] net: ftgmac100: convert to driver model

Cédric Le Goater
In reply to this post by Cédric Le Goater
The driver is based on the previous one and the code is only adapted
to fit the driver model. The support for the Faraday ftgmac100
controller is the same with MAC and MDIO bus support for RGMII/RMII
modes.

Configuration is updated to enable compile again. At this stage, the
driver compiles but is not yet functional.

+  It is fully compliant with IEEE 802.3 specification for

+  Mbps mode only supports full duplex), flow control for full
+  duplex and backpressure for half duplex.
+
+  The FTGMAC100 also implements IP, TCP, UDP checksum offloads

[PATCH v3 05/13] net: ftgmac100: add MDIO bus and phylib support

Cédric Le Goater
In reply to this post by Cédric Le Goater
Implement the MDIO bus read/write functions using the readl_poll_timeout()
routine, initialize the bus and scan for the PHY. RGMII and RMII mode
are supported.

[PATCH v3 06/13] net: ftgmac100: convert the RX/TX descriptor arrays

Cédric Le Goater
In reply to this post by Cédric Le Goater
Use simple arrays under the device priv structure to hold the RX and
TX descriptors and handle memory coherency by invalidating or flushing
the d-cache when required.

Signed-off-by: Cédric Le Goater <[hidden email]>

 At this stage, the drive is functional.

[PATCH v3 13/13] aspeed: ast2500: fix D2-PLL clock setting in RGMII mode

Cédric Le Goater
In reply to this post by Cédric Le Goater
The algorithm in the ast2500_calc_clock_config() routine suffers from
integer rounding and the requested rate does not get the appropriate
set of Numerator, Denumerator, Post Divider parameters.

This is the case for the D2-PLL clock used by the MAC controllers in
RGMII mode. The requested rated is 250MHz but a 251MHz is assigned.

The easiest way to fix this problem is to introduce an array of clock
settings defining the N, M, P parameters for well known frequencies
used by the Aspeed SoC.
