2013-11-22net: tsec: Use portable types and accessors for BDsClaudiu Manoil
Currently, the buffer descriptor (BD) fields cannot be correctly accessed by a little endian processor. This patch fixes the issue by making the access of BDs to be portable among different cpu architectures. Use portable data types for the Rx/Tx buffer descriptor fields. Use portable I/O accessors to insure that the big endian BDs are correctly accessed by little endian cpus too, and to insure proper sync with the H/W. Removed the redundant RTXBD "volatile" type, as proper synchronization around BD data accesses is provided by the I/O accessors now. The "sparse" tool was also used to verify the correctness of these changes. Cc: Scott Wood <scottwood@freescale.com> Signed-off-by: Claudiu Manoil <claudiu.manoil@freescale.com>

Use the __iomem address space marker to address sparse warnings in tsec.c where IO accessors are used, like: tsec.c:394:19: warning: incorrect type in argument 1 (different address spaces) tsec.c:394:19: expected unsigned int volatile [noderef] <asn:2>*addr tsec.c:394:19: got unsigned int *<noident> [...] Add the __iomem address space marker for the tsec pointers to struct tsec_mii_mng memory mapped register regions.

2013-11-22net: tsec: Fix priv pointer in tsec_mcast_addr()Claudiu Manoil
Access to privlist[1] (hardcoded referece to the 2nd tsec's priv area) is neither correct nor does it make sense in the current context. Each tsec dev has access to its own priv instance only, and hence to its own set of group address registers (GADDR) to filter multicast addresses. This fix leads to removal of the unused (faulty) privlist[] and related global static vars. Note that mcast() can be called only after eth_device allocation and init, and hence after priv area allocation, so dev->priv is correctly initialized upon mcast() call.

Instead we explicitly set CONFIG_TSEC_TBICR_SETTINGS for the XPedite5370 & XPedite5500 boards that use a Broadcomm PHY which require Auto-Neg to be disabled to function properly. This addresses a breakage on the P2020 DS & MPC8572 DS boards when used with an SGMII riser card. We also remove setting CONFIG_TSEC_TBICR_SETTINGS on the P1_P2_RDB family of boards as now the default setting is sufficient for them. Additionally, we clean up the code a bit to remove an unnecessary second define.

2010-07-12tsec: fix the return value for tsec_eth_init()Timur Tabi
The Ethernet initialization functions are supposed to return the number of devices initialized, so fix tsec_eth_init() so that they returns the number of TSECs initialized, instead of just zero. This is safe because the return value is currently ignored by all callers, but now they don't have to ignore it. In general, if an function initializes only one device, then it should return a negative number if there's an error. If it initializes more than one device, then it should never return a negative number. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>

2010-01-31tsec: Force TBI PHY to 1000Mbps full duplex in SGMII modePeter Tyser
In SGMII mode the link between a processor's internal TBI PHY and an external PHY should always be 1000Mbps, full duplex. Also, the SGMII interface between an internal TBI PHY and external PHY does not support in-band auto-negotation. Previously, when configured for SGMII mode a TBI PHY would attempt to restart auto-negotation during initializtion. This auto-negotation between a TBI PHY and external PHY would fail and result in unusable ethernet operation. Forcing the TBI PHY and and external PHY to link at 1000Mbps full duplex in SGMII mode resolves this issue of auto-negotation failing. Note that 10Mbps and 100Mbps operation is still possible on the external side of the external PHY even when SGMII is operating at 1000Mbps. The SGMII interface still operates at 1000Mbps, but each byte of data is repeated 100 or 10 times for 10/100Mbps and the external PHY handles converting this data stream into proper 10/100Mbps signalling.
