[U-Boot] [PATCH 0/3 v4] New MIIPHYBB implementation with multi-bus support

[U-Boot] [PATCH 0/3 v4] New MIIPHYBB implementation with multi-bus support

[Luigi 'Comio' Mantellini]

This patch rewrites the miiphybb ( Bit-banged MII bus driver ) in order to
support an 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]);

Patch Changelog:

v1 -- First (broken) release
v2 -- Fix some typos and disable callbacks pointers relacation (if
      CONFIG_RELOC_FIXUP_WORKS is not defined)
v3 -- Do not relocate NULL pointers
v4 -- Code Cleanup.

Luigi 'Comio' Mantellini (3):
  New Bit-banged MII driver (MIIPHYBB) implementation with multi-bus
    support.
  Add bb_miiphy_init call before any ethernet bring-up code.
  Update all board to support new bbmiiphy driver (with multibus
    support)

This, and all the others, are longer than 80 characters.  Please remove 
3 tabs from each and they'll fit

Please remove a tab so this aligns with MDIO_DECLARE.  Apply globally.

[U-Boot] [PATCH 0/3 v4] New MIIPHYBB implementation with multi-bus support

Hi Luigi,

Sorry, I'm going to have to ask you to re-submit again :(  There are a 
few things that need to be addressed

Can you please copy this stuff into a README file (doc/README.bitbangMII 
maybe)?  I'm afraid all this wonderful changelog information will be in 
a place that people won't look.
If it wasn't for other problems with this patch set, I'd do it myself.

Here are the real problems:

bwarren at bwarren-bldsrv$ CROSS_COMPILE=ppc_6xx- ./MAKEALL ppc
...
Configuring for ep8248 board...
board.c:87:20: error: miihpy.h: No such file or directory
board.c:87:20: error: miihpy.h: No such file or directory
board.c: In function 'board_init_r':
board.c:950: warning: implicit declaration of function 'bb_miiphy_init'
make[1]: *** [board.o] Error 1
make: *** [lib_ppc/libppc.a] Error 2

And all sorts of other PPC boards fail too.  Looks like a typo.

Ben
