This patch adds the support for high speed in usb device framework and usbtty driver. This feature has been kept within a macro CONFIG_USBD_HS, so the board configuration files have to define this macro to enable high speed support. Along with that specific peripheral drivers also need to define a function to let the framework know that the enumeration has happened at high speed. This function prototype is "int is_usbd_high_speed(void)" Signed-off-by:

This defines the basics of a new boot time measurement feature. This allows logging of very accurate time measurements as the boot proceeds, by using an available microsecond counter. To enable the feature, define CONFIG_BOOTSTAGE in your board config file. Also available is CONFIG_BOOTSTAGE_REPORT which will cause a report to be printed just before handing off to the OS. Most IDs are not named at this stage. For that I would first like to renumber them all. Timer summary in microseconds: Mark Elapsed Stage 0 0 reset 205,000 205,000 board_init_f 6,053,000 5,848,000 bootm_start 6,053,000 0 id=1 6,058,000 5,000 id=101 6,058,000 0 id=100 6,061,000 3,000 id=103 6,064,000 3,000 id=104 6,093,000 29,000 id=107 6,093,000 0 id=106 6,093,000 0 id=105 6,093,000 0 id=108 7,089,000 996,000 id=7 7,089,000 0 id=15 7,089,000 0 id=8 7,097,000 8,000 start_kernel Signed-off-by:

The commit message of a28afca5 (Add uboot "fdt_high" enviroment variable) states that fdt_high behaves similarly to the existing initrd_high. But fdt_high actually has an outstanding difference from initrd_high. The former specifies the start address, while the later specifies the end address. As fdt_high and initrd_high will likely be used together, it'd be nice to have them behave same. The patch changes the behavior of fdt_high to have it aligned with initrd_high. The document of fdt_high in README is updated with an example to demonstrate the usage of this environment variable. Signed-off-by:

This patch adds support for console output before the console is inited. The main purpose of this is to deal with a very early panic() which would otherwise cause a silent hang. A new board_pre_console_putc() function is added to the board API. If provided by the board it will be called in the event of console output before the console is ready. This function should turn on all UARTs and spray the character out if it possibly can. The feature is controlled by a new CONFIG_PRE_CONSOLE_PUTC option. Signed-off-by:

TPM (Trusted Platform Module) is an integrated circuit and software platform that provides computer manufacturers with the core components of a subsystem used to assure authenticity, integrity and confidentiality. This driver supports version 1.2 of the TCG (Trusted Computing Group) specifications. The TCG specification defines several so called localities in a TPM chip, to be controlled by different software layers. When used on a typical x86 platform during the firmware phase, only locality 0 can be accessed by the CPU, so this driver even while supporting the locality concept presumes that only locality zero is used. This implementation is loosely based on the article "Writing a TPM Device Driver" published on http://ptgmedia.pearsoncmg.com Compiling this driver with DEBUG defined will generate trace of all accesses to TMP registers. This driver has been tested and is being used in three different functional ChromeOS machines (Pinetrail and Sandy Bridge Intel chipsets) all using the same Infineon SLB 9635 TT 1.2 device. A u-boot cli command allowing access to the TPM was also implemented and is being submitted as a second patch. Change-Id: I22a33c3e5b2e20eec9557a7621bd463b30389d73 Signed-off-by:

Several macros are used to identify and locate the microcode binary image that U-boot needs to upload to the QE or Fman. Both the QE and the Fman use the QE Firmware binary format to package their respective microcode data, which is why the same macros are used for both. A given SOC will only have a QE or an Fman, so this is safe. Unfortunately, the current macro definition and usage has inconsistencies. For example, CONFIG_SYS_FMAN_FW_ADDR was used to define the address of Fman firmware in NOR flash, but CONFIG_SYS_QE_FW_IN_NAND contains the address of NAND. There's no way to know by looking at a variable how it's supposed to be used. In the future, the code which uploads QE firmware and Fman firmware will be merged. Signed-off-by:

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). Signed-off-by:

This new option allows U-Boot to embed a binary device tree into its image to allow run-time control of peripherals. This device tree is for U-Boot's own use and is not necessarily the same one as is passed to the kernel. The device tree compiler output should be placed in the $(obj) rooted tree. Since $(OBJCOPY) insists on adding the path to the generated symbol names, to ensure consistency it should be invoked from the directory where the .dtb file is located and given the input file name without the path.

Interactive DDR debugging provides a user interface to view and modify SPD, DIMM parameters, board options and DDR controller registers before DDR is initialized. With this feature, developers can fine-tune DDR for board bringup and other debugging without frequently having to reprogram the flash. To enable this feature, define CONFIG_FSL_DDR_INTERACTIVE in board header file and set an environment variable to activate it. Syntax: setenv ddr_interactive on After reset, U-boot prompts before initializing DDR controllers FSL DDR> The available commands are print print SPD and intermediate computed data reset reboot machine recompute reload SPD and options to default and recompute regs edit modify spd, parameter, or option compute recompute registers from current next_step to end next_step shows current next_step help this message go program the memory controller and continue with u-boot The first command should be "compute", which reads data from DIMM SPDs and board options, performs the calculation then stops before setting DDR controller. A user can use "print" and "edit" commands to view and modify anything. "Go" picks up from current step with any modification and compltes the calculation then enables the DDR controller to continue u-boot. "Recompute" does it over from fresh reading. Signed-off-by:
