When this happens, the idle error count will read 0xFF after autonegotiation completes. Reset the PHY when in that state. is it possible that we get the link to late and barebox reports "Network is down". The problem is that ksz9031_config_init is called again in an error case. In this case autoneg will restart but waiting for finish is missing. Signed-off-by: Christian Hemp <c.hemp@phytec.de> Tested-by: Stefan Müller-Klieser <s.mueller-klieser@phytec.de>
* | | usbnet: increase bulk message timeoutNikita Yushchenko2018-05-021-1/+1
| |/ |/| | | | | | | | | | | | | | | | | | | | | Timeout of 1ms is too low for case when device operates in Full Speed mode. This causes most incoming frames to be lost. Since timeout is only used to get out of polling loop in case of no response from hardware, increasing it should be safe for all platforms.

| | | | | | | | | While cpsw is probe dt, it accepts only slaves nodes with "phy_id" property. In case of fixed-link there are no "phy_id" property and probe would be failed.

When the EEPROM is populated from iNVM, the signature is not valid, which causes other parts of the driver to fall over. To fix this just ignore the EEPROM in that case.

| | | | | | | | | | | | | | | | | | | | | | | | | | Some supported flash devices (e.g. SST25VF040) are write protected after power up. If the device holds a valid firmware image the i210 can handle that just fine. If however there is no firmware programmed, a procedure is needed to remove this protection before an image can be flashed. So implement the needed callbacks to make the commands protect and unprotect do the right thing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Erasing the whole flash takes approximately 7s on one of my test machines. Expand the timeout accordingly. Note however that it is in general not allowed to hold the flash semaphore for so long and "firmware might implement a timeout mechanism and take ownership of the relevant [lock]" after one second. So a chip erase should better only be done when firmware doesn't make use of the flash.

* | net/e1000: provide access to iNVM even if a flash is presentUwe Kleine-König2017-11-242-67/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An i210 (aka e1000_igb) supports two different non-volatile storages for configuration. There is a built-in one-time programmable storage called iNVM and an optional external SPI-Flash. If a flash is populated and contains a valid configuration image the iNVM is not used (if I understood the documentation correctly). Still the iNVM can be useful if the flash is not configured. Also the iNVM contains manufacturing identification information. So it makes sense to provide the invm device even if a flash is present. This patch also cleans up some confusion that suggests that invm is a way to access the (simulated) eeprom structures and drops some unused enum values.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Nothing in the documentation suggests that the time to get a semaphore depends on the size of the (optional) eeprom and I doubt there is a relation. Given that 2048 is the maximal value for word_size unless a flash is used to emulate the eeprom, pick 2049 as alternative arbitrary value that probably doesn't result in regressions. This drops the only user of ->word_size outside of eeprom.c which allows easier restructurings there in the future.
