* e1000: Allow direct access to the E1000 SPI EEPROM deviceKyle Moffett2011-10-28-2/+671
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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/+24
| | | | | | | | | | | | 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 Moffett2011-10-28-71/+74
| | | | | | | | | | | | | | | | | | | | | | | 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.

| * da850evm: Move LPSC configuration to board_early_init_f()Christian Riesch2011-10-27-9/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit f1d2b313c9eb6808d30c16a9eb5251240452a56c the serial port of the da850evm is accessed before the UART2 peripheral of the SoC is powered on in the function board_init() in board/davinci/da8xxevm/da850evm.c. When u-boot is used in conjunction with the UBL (user boot loader, see doc/README.davinci) on this board, the UART2 peripheral is already turned on by UBL at the time u-boot is started. Hence, the wrong initialization sequence is not noticed by most users. However, if UBL is not used, u-boot must power on the peripheral before using it. This patch adds a board_early_init_f() function for the LPSC configuration to the da850evm board configuration.

Combined with the 100uA pull-up resistors in the OMAP3, this raises the ground level to 400mV. Adding crosstalk between the pixel clock and the HS/VS signals on the flat cable (a ground line in between would have been nice), logic 0 levels can raise up to 650mV. This exceeds the camera input pins VIL maximum voltage. This change suggested-by Laurent Pinchart Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
| * omap: overo: Configure mux for gpio10Steve Sakoman2011-10-27-1/+1
| | | | | | | | | | | | | | | | | | | | This pad was previously configured for sysclkout_1. This patch changes the configuration to gpio_10 to reduce radiated noise from the 26Mhz clock, as well as make the pin more generally useful.
