* omap3_beagle: Flush UART3 xmit on enable if TEMT is brokenManfred Huber2013-04-08-8/+0
| | | | | | | | | | | | Flush UART3 xmit on enable if TEMT is broken On some OMAP3 devices when UART3 is configured for boot mode before SPL starts only THRE bit is set. We have to empty the transmitter before initialization starts. This patch avoids the use of CONFIG_SYS_NS16550_BROKEN_TEMT.

| * ARM: implement some Cortex-A9 errata workaroundsStephen Warren2013-03-13-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various errata exist in the Cortex-A9 CPU, and may be worked around by setting some bits in a CP15 diagnostic register. Add code to implement the workarounds, enabled by new CONFIG_ options. This code was taken from the Linux kernel, v3.8, arch/arm/mm/proc-v7.S, and modified to remove the logic to conditionally apply the WAR (since we know exactly which CPU we're running on given the U-Boot configuration), and use r0 instead of r10 for consistency with the rest of U-Boot's cpu_init_cp15().

| * | lcd: add option for board specific splash screen preparationNikita Kiryanov2013-03-08-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently there is no logical place to put the code that prepares the splash image data. The splash image data should be ready in memory before bmp_display() is called, and after the environment is ready (since lcd.c looks for the splash image in an address specified by the environment variable "splashimage"). Our window of opportunity in board_init_r() is therefore: between env_relocate() and bmp_display(), and from the available options only the lcd related functions in drv_lcd_init() seem appropriate for such lcd oriented code. Add the option to prepare the splash image data in lcd_logo() right before it is sent to be displayed.

* | | Feature Removal: disable "mtest" command by defaultWolfgang Denk2013-03-11-1/+2
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | sandbox: Add un/map_sysmen() to deal with sandbox's ram_bufSimon Glass2013-02-28-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sandbox doesn't actually provide U-Boot access to the machine's physical memory. Instead it provides a RAM buffer of configurable size, and all memory accesses are within that buffer. Sandbox memory starts at 0 and is CONFIG_DRAM_SIZE bytes in size. Allowing access outside this buffer might produce unpredictable results in the event of an error, and would expose the host machine's memory architecture to the sandbox U-Boot. Most U-Boot functions assume that they can just access memory at given address. For sandbox this is not true. Add a map_sysmem() call which converts a U-Boot address to a system address. In most cases this is a NOP, but for sandbox it returns a pointer to that memory inside the RAM buffer. To get a U-Boot feature to work correctly within sandbox, you should call map_sysmem() to get a pointer to the address, and then use that address for any U-Boot memory accesses.

This makes U-Boot to hang while waiting for TEMT to be set. Add a new option to avoid this: CONFIG_SYS_NS16550_BROKEN_TEMT 16550 UART set the Transmitter Empty (TEMT) Bit when all output has finished and the transmitter is totally empty. U-Boot waits for this bit to be set to initialize the serial console. On some broken platforms this bit is not set in SPL making U-Boot to hang while waiting for TEMT. Define this option to avoid it.

This can address the security risk of untrusted data being used during boot. Any time you load untrusted data you expose yourself to a bug in the code. The attacker gets to choose the data so can sometimes carefully craft it to exploit a bug. We try to avoid touching user-controlled data during a verified boot unless strictly necessary. Since the default environment is good enough in this case (or you would just change it), this gets around the problem by just not loading the environment. When CONFIG_DELAY_ENVIRONMENT is defined, it is convenient to have a run-time way of enabling loading of the environment. Add this to the fdt as /config/delay-environment.

* | x86: Allow excluding reset vector code from u-bootGabe Black2012-11-28-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | When running from coreboot we don't want this code. This version works by ifdef-ing out all of the code that would go into those sections and all the code that refers to it. The sections are then empty, and the linker will either leave them empty for the loader to ignore or remove them entirely.
