* e1000e : Correct Rx Threshold granularityRuchika Gupta2012-12-15-0/+10
| | | | | | | | | | | | | | In e1000e driver, Rx descriptor queue is used such that hardware can add only one descriptor at a time. So the WTHRESH granularity in RXDCTL should be set to single descriptor. This would ensure that every time controller fills a Rx descriptor, it is flushed to host memory. Earlier this granularity was in cache line units i.e 2 descriptors. This leads to controller always waiting for 2 descriptors before flushing them out. But since not more than one Rx BD is actually available , the accumulation condition never gets hit.

* e1000: Allow direct access to the E1000 SPI EEPROM deviceKyle Moffett2011-10-28-1/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As a part of the manufacturing process for some of our custom hardware, we are programming the EEPROMs attached to our Intel 82571EB controllers from software using U-Boot and Linux. This code provides several conditionally-compiled features to assist in our manufacturing process: CONFIG_CMD_E1000: This is a basic "e1000" command which allows querying the controller and (if other config options are set) performing EEPROM programming. In particular, with CONFIG_E1000_SPI this allows you to display a hex-dump of the EEPROM, copy to/from main memory, and verify/update the software checksum. CONFIG_E1000_SPI_GENERIC: Build a generic SPI driver providing the standard U-Boot SPI driver interface. This allows commands such as "sspi" to access the bus attached to the E1000 controller. Additionally, some E1000 chipsets can support user data in a reserved space in the E1000 EEPROM which could be used for U-Boot environment storage. CONFIG_E1000_SPI: The core SPI access code used by the above interfaces. For example, the following commands allow you to program the EEPROM from a USB device (assumes CONFIG_E1000_SPI and CONFIG_CMD_E1000 are enabled): usb start fatload usb 0 $loadaddr 82571EB_No_Mgmt_Discrete-LOM.bin e1000 0 spi program $loadaddr 0 1024 e1000 0 spi checksum update Please keep in mind that the Intel-provided .eep files are organized as 16-bit words. When converting them to binary form for programming you must byteswap each 16-bit word so that it is in little-endian form. This means that when reading and writing words to the SPI EEPROM, the bit ordering for each word looks like this on the wire: Time >>> ------------------------------------------------------------------ ... [7, 6, 5, 4, 3, 2, 1, 0, 15, 14, 13, 12, 11, 10, 9, 8], ... ------------------------------------------------------------------ (MSB is 15, LSB is 0).

* e1000: Export core EEPROM access functions for SPI supportKyle Moffett2011-10-28-17/+5
| | | | | | | | | | | | A followup patch will be adding a configurable feature to enable programming of E1000 EEPROMs from the command line or via the generic U-Boot SPI interface. In order for it to work it needs access to certain E1000-internal functions, so export those in the e1000.h header file.

* e1000: Rewrite EEPROM checksum error to give more informationKyle Moffett2011-10-28-18/+28
| | | | | | | | As an aide to debugging, we should print out the expected value of the EEPROM checksum in addition to just saying that it is wrong. Signed-off-by: Kyle Moffett <Kyle.D.Moffett@boeing.com> Cc: Ben Warren <biggerbadderben@gmail.com>
* e1000: Restructure and streamline PCI device probingKyle Moffett2011-10-28-64/+62
| | | | | | | | | | | | | | | | | | | | | | | By allocating the e1000 device structures much earlier, we can easily generate better error messages and siginficantly clean things up. The only user-visable change (aside from reworded error messages) is that a detected e1000 device which fails to initialize due to software or hardware error will still be allocated a device number. As one example, consider a system with 2 e1000 PCI devices where the first controller has a corrupted EEPROM. Using the old code the second controller would be "e1000#0", while with this change it would be "e1000#1". This change should hopefully make such EEPROM errors much more straightforward to handle correctly in boot scripts and the like. It is also necessary for a followup patch which allows SPI programming of an e1000 controller's EEPROM even if the checksum is invalid.
