* Add config option for disabling DM9000-SROM support.Remy Bohmer2009-06-08-8/+8
| | | | | | | | | | | | | | | Some boards do not have SROM support for the DM9000 network adapter. Instead of listing these board names in the driver code, make this option configurable from the board config file. It also removes a build warning for the at91sam9261ek board: 'dm9000x.c:545: warning: 'read_srom_word' defined but not used' And it repaires the trizepsiv board build which was broken around the same routines Signed-off-by: Remy Bohmer <linux@bohmer.net> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
* dm9000 EEPROM reading bugfixDavid Brownell2009-04-28-6/+6
| | | | | | | | | | | | Make the U-Boot dm9000 driver read addresses from EEPROM just like Linux does ... read six bytes, instead of reading twelve bytes and then discarding every other one. Using the right Ethernet address is a big win.

* dm9000 remove dead external phy support, gpio fixAndrew Dyer2008-08-26-144/+15
| | | | | | | | | | | | | | | | dm9000 has code to detect and initialize external phy parts, but later on in the code the part is forced to use the internal phy unconditionally. Remove the unused/untested code. change the GPIO initialization so that only the GPIO used as an internal phy reset (hardwired in the chip) is set as an output. The remaining GPIO need to be handled by board specific code to prevent possible drive conflicts. Set as inputs for safety. replace a few magic numbers with defines Signed-off-by: Andrew Dyer <adyer@righthandtech.com> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>

* | | DM9000 fix status check fail 0x6d error for trizeps boardRemy Bohmer2008-06-05-9/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the Application Notes of the DM9000, only the 2 bits 0:1 of the status byte need to be checked to identify a valid packet in the fifo But, The several different Application Notes do not all speak the same language on these bits. They do not disagree, but only 1 Application Note noted explicitly that only these 2 bits need to be checked. Even the datasheets do not mention anything about these 2 bits. Because the old code, and the kernel check the whole byte, I left this piece untouched. However, I tested all board/DM9000[A|E|EP] devices with this 2 bit check, so it should work. Notice, that the 2nd iteration through this receive loop (when a 2nd packet is in the fifo) is much shorter now, compared to the older U-boot driver code, so that we can maybe run into a hardware condition now that was never seen before, or maybe was seen very unfrequently. Additionaly added a cleanup of a stack variable. Signed-off-by: Remy Bohmer <linux@bohmer.net> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>

* | | DM9000: Make driver work properly for DM9000ARemy Bohmer2008-06-04-39/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DM9000A network controller does not work with the U-boot DM9000x driver. Analysis showed that many incoming packets are lost. The DM9000A Application Notes V1.20 (section 5.6.1) recommend that the poll to check for a valid rx packet be done on the interrupt status register, not directly by performing the dummy read and the rx status check as is currently the case in the u-boot driver. When the recommended poll is done as suggested the driver starts working correctly on 10Mbit/HD, but on 100MBit/FD packets come in faster so that there can be more than 1 package in the fifo at the same time. The driver must perform the rx-status check in a loop and read and handle all packages until there is no more left _after_ the interrupt RX flag is set.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the application notes of the DM9000 v1.22 chapter 5.2 bullet 2, the reset procedure must be done twice to properly reset the DM9000 by means of software. This errata is not needed anymore for the DM9000A, but it does not bother it. This change has been tested with DM9000A, DM9000E, DM9000EP.

* | | DM9000: Add data bus-width auto detection.Remy Bohmer2008-06-04-58/+129
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The U-boot DM9000x driver contains a compile time bus-width definition for the databus connected to the network controller. This compile check makes the code unclear, inflexible and is unneccessary. It can be asked to the network controller what its bus-width is by reading bits 6 and 7 of the interrupt status register. The linux kernel already uses a runtime mechanism to determine this bus-width, so the implementation below looks somewhat like that implementation.
