* ARM: OMAP5: Fix warm reset with USB cable connectedLokesh Vutla2013-05-101-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Warm reset on OMAP5 freezes when USB cable is connected. Fix requires PRM_RSTTIME.RSTTIME1 to be programmed with the time for which reset should be held low for the voltages and the oscillator to reach stable state. There are 3 parameters to be considered for calculating the time, which are mostly board and PMIC dependent. -1- Time taken by the Oscillator to shut + restart -2- PMIC OTP times -3- Voltage rail ramp times, which inturn depends on the PMIC slew rate and value of the voltage ramp needed. In order to keep the code in u-boot simple, have a way for boards to specify a pre computed time directly using the 'CONFIG_OMAP_PLATFORM_RESET_TIME_MAX_USEC' option. If boards fail to specify the time, use a default as specified by 'CONFIG_DEFAULT_OMAP_RESET_TIME_MAX_USEC' instead. Using the default value translates into some ~22ms and should work in all cases. However in order to avoid this large delay hiding other bugs, its recommended that all boards look at their respective data sheets and specify a pre computed and optimal value using 'CONFIG_OMAP_PLATFORM_RESET_TIME_MAX_USEC' In order to help future board additions to compute this config option value, add a README at doc/README.omap-reset-time which explains how to compute the value. Also update the toplevel README with the additional option and pointers to doc/README.omap-reset-time.

| * New command bootmenu: ANSI terminal boot menu supportPali Rohár2013-03-291-0/+115
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "bootmenu" command uses U-Boot menu interfaces and provides a simple mechanism for creating menus with several boot items. When running this command the menu will be assembled as defined by a set of environment variables which contain a title and command key-value pairs. The "Up" and "Down" keys are used for navigation through the items. Current active menu item is highlighted and can be selected using the "Enter" key. The command interprets and generates various ANSI escape sequencies, so for proper menu rendering and item selection the used terminal should support them.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "mtest" command is of little practical use (if any), and experience has shown that a large number of board configurations define useless or even dangerous start and end addresses. If not even the board maintainers are able to figure out which memory range can be reliably tested, how can we expect such from the end users? As this problem comes up repeatedly, we rather do not enable this command by default, so only people who know what they are doing will be confronted with it. As this changes the user interface, we allow for a grace period before this change takes effect. For now, we make "mtest" configurable through the CONFIG_CMD_MEMTEST variable, which is defined in include/config_cmd_default.h; we also add an entry to doc/feature-removal-schedule.txt which announces the removal of this default setting in two releases from now, i. e. with v2013.07.

By enabling key press method, we can enter debug mode to have a chance to boot without using other tools to recover the board. CONFIG_FSL_DDR_INTERACTIVE needs to be defined in header file.
