This is a rework of the DM9000 driver to support registering
interfaces dynamically (i.e. determine how many ethernet chips we have
at boot and register 0, 1, 2, or more). It was tested on a
yet-to-be-submitted board which is based on the PXA270 + 0, 1, or 2
DM9000 chips.
To maintain backwards compatibility with older board files, we add a
new initialize function taking the io address, data address, and
availability of a SROM chip. The old initialize function is now a
shim around this new initialize function but provides the parameters
based on the old DM9000 preprocessor symbols.
I have compile-tested this on the following:
at91sam9261ek_dataflash_cs0_defconfig
davinci_dm355evm_defconfig
davinci_dm355leopard_defconfig
lp8x4x_defconfig
pm9261_defconfig
scb9328_defconfig
devkit8000_defconfig
colibri_pxa270_defconfig
trizepsiv_defconfig
vpac270_nor_128_defconfig
I have not compile-tested the following:
M5253DEMO
ip04
I have board tested this on a yet-to-be-upstreamed port of a pxa270 board that
reads an i2c eeprom to determine which (and how many) ethernet chips are
enabled.

These are public just so that a command (presumably only available on one board - trizepsiv) can access the eeprom of a dm9000. It also currently assumes that there is only one dm9000 on that board. I think it should not expose any internal dm9000 struct.

This patch changes the initialization function - dm9000_initialize - to support registering multiple (and possibly dynamic) numbers of dm9000 devices. This patch consists of: * Change the board_info struct to a private struct under eth_device. * Add io address/data address/srom availability information to this private struct. * Replace all uses of DM9000_IO/DM9000_DATA with new members, ensure that the eth_device struct propagates down to all helper functions. * Call dm9000_initialize_ex() with filled in information from the old preprocessor symbols (DM9000_IO, DM9000_DATA, etc.) Overall the following parameters have been moved over to being a per-chip setting: DM9000_IO, DM9000_DATA, CONFIG_DM9000_NO_SROM while the following is still a global setting affecting all chips: CONFIG_DM9000_BYTE_SWAPPED And the following has been removed entirely: CONFIG_DM9000_BASE (was only used in a single printf) Signed-off-by: Andrew Ruder <andrew.ruder@elecsyscorp.com> Cc: Joe Hershberger <joe.hershberger@gmail.com> --- drivers/net/dm9000x.c | 382 +++++++++++++++++++++++++++++--------------------- include/dm9000.h | 2 - 2 files changed, 220 insertions(+), 164 deletions(-) diff --git a/drivers/net/dm9000x.c b/drivers/net/dm9000x.c index 9778ef9..d0ea5d7 100644 --- a/drivers/net/dm9000x.c +++ b/drivers/net/dm9000x.c @@ -55,6 +55,7 @@ TODO: external MII is not functional, only internal at the moment. #include <asm/io.h> #include <dm9000.h> #include <linux/compiler.h> +#include <malloc.h> #include "dm9000x.h" @@ -80,7 +81,9 @@ TODO: external MII is not functional, only internal at the moment. #endif /* Structure/enum declaration ------------------------------- */ -typedef struct board_info { +struct dm9000_priv { + ulong data_base;

It appears that every place you added it you simply dereference dev->priv. For the cases where you actually need a member of eth_device you should pas that as a separate parameter pointer. The reason for this is the eth_device structure is going away. In the driver model implementation everything is a udevice pointer. You still have your priv inside there, so that's the thing to pass around. It will make far less churn when adding driver model support to DM9000. > +}; > > > /* function declaration ------------------------------------- */ > -static int dm9000_probe(void); > -static u16 dm9000_phy_read(int);

If you feel like adding a patch to the end of this series to move it that would be great! You may also want to move the reset to the _initialize() function instead of the init() op. I assume that resetting will clear the ethaddr that's configured. If you decide to leave the reset in the init() op, you'll need to call the new write_hwaddr() op yourself here as well as register it. Hopefully this will all get better when the network stack is smarter and doesn't call the init() op for each command. > > /* Activate DM9000 */ > /* RX enable */ > - DM9000_iow(DM9000_RCR, RCR_DIS_LONG | RCR_DIS_CRC | RCR_RXEN);
