* miiphy: miiphyutil.c: fix compile warningAnatolij Gustschin2011-04-30-4/+8
| | | | | | | | | | Fix warning introduced while recent PHY Lib changes: miiphyutil.c: In function 'miiphy_read': miiphyutil.c:304: warning: comparison is always false due to limited range of data type Signed-off-by: Anatolij Gustschin <agust@denx.de> Cc: Andy Fleming <afleming@freescale.com>
* Create PHY Lib for U-BootAndy Fleming2011-04-20-36/+145
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extends the mii_dev structure to participate in a full-blown MDIO and PHY driver scheme. The mii_dev structure and miiphy calls are modified in such a way to allow the original mii command and miiphy infrastructure to work as before, but also to support a new set of APIs which allow (among other things) sharing of PHY driver code and 10G support The mii command will continue to support normal PHY management functions (Clause 22 of 802.3), but will not be changed to support 10G (Clause 45). The basic design is similar to PHY Lib from Linux, but simplified for U-Boot's network and driver infrastructure. We now have MDIO drivers and PHY drivers An MDIO driver provides: read write reset A PHY driver provides: (optionally): probe config - initial setup, starting of auto-negotiation startup - waiting for AN, and reading link state shutdown - any cleanup needed The ethernet drivers interact with the PHY Lib using these functions: phy_connect() phy_config() phy_startup() phy_shutdown() Each PHY driver can be configured separately, or all at once using config_phylib_all_drivers.h (added in the patch which adds the drivers) We also provide generic drivers for Clause 22 (10/100/1000), and Clause 45 (10G) PHYs. We also implement phy_reset(), and call it in phy_connect(). Because phy_reset() is essentially the same as miiphy_reset, but: a) must support 10G PHYs, and b) should use the phylib primitives, we implement miiphy_reset, using phy_reset(), but only when CONFIG_PHYLIB is set. Otherwise, we just use the old version. In this way, we save on compile size, even if we don't manage to save code size.

* miiphy: convert to linux/mii.hMike Frysinger2011-01-09-25/+25
| | | | | | | | The include/miiphy.h header duplicates a lot of things from linux/mii.h. So punt all the things that overlap to keep the API simple and to make merging between U-Boot and Linux simpler. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* miiphy: leverage current_mii cache moreMike Frysinger2010-08-09-2/+16
| | | | | | | | | | For code that uses miiphy_{read,write}, every call invokes a full look up of the mii list. There is already a "current_mii" cache that is used by some code, but have the miiphy_{read,write} function use it as well. This does increase the code size slightly, but I think it's worth it.

* miiphy: unify device list lookupMike Frysinger2010-08-09-60/+40
| | | | | | | | | Rather than have every func re-implement the list walking code, do it one local function. This shrinks the resulting object code a little while making the source much more manageable. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>

* net: Use 0.5 sec timeout in miiphy_reset() instead of counting loopStefan Roese2010-02-06-6/+6
| | | | | | | | | | | | | This patch fixes a problem I've notived on a buggy PPC4xx system. This system has problems with the PHY MDIO communication and seemed to be stuck/crashed in miiphy_reset(). But degugging revealed, that the CPU didn't crash, but "only" hung in this counting loop for about 2 minutes. This patch now uses a real timeout of 0.5 seconds (as mentioned in the comment in miiphy_reset). Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>

* common/miiphyutil.c: Cleanup MII_DEBUG and debug()Shinya Kuribayashi2008-02-14-22/+9
| | | | | | | | | | | | Current MII_DEBUG is confusing in two ways. One is useless define-then- undef at the top of the file. The other is there is only one debug() in this file, and that doesn't seem worthwhile to bother having MII_DEBUG. While there are many useful printf()/puts() debug codes, but they are for DEBUG, not for MII_DEBUG. This patch tries to put them all together into MII_DEBUG and debug().

* NET: Add Ethernet 1000BASE-X support for PPC4xxLarry Johnson2007-11-06-58/+93
| | | | | | | | | | This patch adds support for 1000BASE-X to functions "miiphy_speed ()" and "miiphy_duplex()". It also adds function "miiphy_is_1000base_x ()", which returns non-zero iff the PHY registers are configured for 1000BASE-X. The "mii info" command is modified to distinguish between 1000BASE-T and -X. Signed-off-by: Larry Johnson <lrj@acm.org> Signed-off-by: Ben Warren <bwarren@qstreams.com>
