* Replace CONFIG_RELOC_FIXUP_WORKS by CONFIG_NEEDS_MANUAL_RELOCWolfgang Denk2010-10-29-1/+1
| | | | | | | | | | | By now, the majority of architectures have working relocation support, so the few remaining architectures have become exceptions. To make this more obvious, we make working relocation now the default case, and flag the remaining cases with CONFIG_NEEDS_MANUAL_RELOC.

| | | | | | | | | | | Commit 6e37b1a3a25004d3df5867de49fff6b3fc9c4f04 modifies several net calls to take a (const char *) parameter instead of (char *), but in some cases the modified functions call other functions taking (char *). The end result is warnings about discarding the const qualifier. This patch fixes these other function signatures. Signed-off-by: Ben Warren <biggerbadderben@gmail.com>

* Rewrite the miiphybb (Bit-banged MII bus driver) in order to support an ↵Luigi 'Comio' Mantellini2009-10-10-104/+242
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | arbitrary number of mii buses. This feature is useful when your board uses different mii buses for different phys and all (or a part) of these buses are implemented via bit-banging mode. The driver requires that the following macros should be defined into the board configuration file: CONFIG_BITBANGMII - Enable the miiphybb driver CONFIG_BITBANGMII_MULTI - Enable the multi bus support If the CONFIG_BITBANGMII_MULTI is not defined, the board's config file needs to define at least the following macros: MII_INIT - Generic code to enable the MII bus (optional) MDIO_DECLARE - Declaration needed to access to the MDIO pin (optional) MDIO_ACTIVE - Activate the MDIO pin as out pin MDIO_TRISTATE - Activate the MDIO pin as input/tristate pin MDIO_READ - Read the MDIO pin MDIO(v) - Write v on the MDIO pin MDC_DECLARE - Declaration needed to access to the MDC pin (optional) MDC(v) - Write v on the MDC pin The previous macros make the driver compatible with the previous version (that didn't support the multi-bus). When the CONFIG_BITBANGMII_MULTI is also defined, the board code needs to fill the bb_miiphy_buses[] array with a record for each required bus and declare the bb_miiphy_buses_num variable with the number of mii buses. The record (struct bb_miiphy_bus) has the following fields/callbacks (see miiphy.h for details): char name[] - The symbolic name that must be equal to the MII bus registered name int (*init)() - Initialization function called at startup time (just before the Ethernet initialization) int (*mdio_active)() - Activate the MDIO pin as output int (*mdio_tristate)() - Activate the MDIO pin as input/tristate pin int (*set_mdio)() - Write the MDIO pin int (*get_mdio)() - Read the MDIO pin int (*set_mdc)() - Write the MDC pin int (*delay)() - Delay function void *priv - Private data used by board specific code The board code will look like: struct bb_miiphy_bus bb_miiphy_buses[] = { { .name = miibus#1, .init = b1_init, .mdio_active = b1_mdio_active, ... }, { .name = miibus#2, .init = b2_init, .mdio_active = b2_mdio_active, ... }, ... int bb_miiphy_buses_num = sizeof(bb_miiphy_buses) / sizeof(bb_miiphy_buses[0]); Signed-off-by: Luigi 'Comio' Mantellini <luigi.mantellini@idf-hit.com> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
* MIIPHYBB: Return 0xFFFF if the PHY is not asserting TA.Richard Retanubun2009-07-22-0/+7
| | | | | | | | | | | | This patch sets the returned value to 0xFFFF if the PHY does not exist and does not assert Transfer Acknowledge. A NULL check for the value pointer is also added for buffer overflow protection. Without this patch 'mii info' will show 'phantom' devices because the value will be not be initialized and return with some random value.
