* dm: timer: Correct timer init ordering after relocationSimon Glass2016-03-17-1/+3
| | | | | | | | | | | Commit 1057e6c broke use of the timer with driver model. If the timer is used before relocation, then it becomes broken after relocation. This prevents some x86 boards from booting. Fix it.

* efi_loader: Implement memory allocation and mapAlexander Graf2016-03-15-0/+3
| | | | | | | | | | | | | | | | | | | The EFI loader needs to maintain views of memory - general system memory windows as well as used locations inside those and potential runtime service MMIO windows. To manage all of these, add a few helpers that maintain an internal representation of the map the similar to how the EFI API later on reports it to the application. For allocations, the scheme is very simple. We basically allow allocations to replace chunks of previously done maps, so that a new LOADER_DATA allocation for example can remove a piece of the RAM map. When no specific address is given, we just take the highest possible address in the lowest RAM map that fits the allocation size.

* efi_loader: Add runtime servicesAlexander Graf2016-03-15-0/+4
| | | | | | | | | | | | | | | | | After booting has finished, EFI allows firmware to still interact with the OS using the "runtime services". These callbacks live in a separate address space, since they are available long after U-Boot has been overwritten by the OS. This patch adds enough framework for arbitrary code inside of U-Boot to become a runtime service with the right section attributes set. For now, we don't make use of it yet though. We could maybe in the future map U-boot environment variables to EFI variables here.

* console: Add a console bufferSimon Glass2015-11-19-0/+10
| | | | | | | | | | | | | | | | | | | It is useful to be able to record console output and provide console input via a buffer. This provides sandbox with the ability to run a command and check its output. If the console is set to silent then no visible output is generated. This also provides a means to fix the problem where tests produce unwanted output, such as errors or warnings. This can be confusing. We can instead set the console to silent and record this output. It can be checked later in the test if required. It is possible that this may prove useful for non-test situations. For example the console output may be suppressed for normal operations, but recorded and stored for access by the OS. That feature is not implemented at present.

* | allow LED initialization without STATUS_LED_BOOTBernhard Nortmann2015-10-24-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For current U-Boot to initialize status LEDs via status_led_init(), it is required to have both CONFIG_STATUS_LED and STATUS_LED_BOOT defined. This may be a particular concern with GPIO LEDs, where __led_init() is required to correctly set up the GPIO (gpio_request and gpio_direction_output). Without STATUS_LED_BOOT the initialization isn't called, which could leave the user with a non-functional "led" command - due to the fact that the LED routines in gpio_led.c use gpio_set_value() just fine, but the GPIO never got set up properly in the first place. I think having CONFIG_STATUS_LED is sufficient to justify a corresponding call to status_led_init(), even with no STATUS_LED_BOOT defined. To do so, common/board_r.c needs call that routine, so it now is exposed via status_led.h.

* ARM: Implement non-cached memory supportThierry Reding2014-12-18-0/+11
| | | | | | | | | | | | | | | | | | | | | | Implement an API that can be used by drivers to allocate memory from a pool that is mapped uncached. This is useful if drivers would otherwise need to do extensive cache maintenance (or explicitly maintaining the cache isn't safe). The API is protected using the new CONFIG_SYS_NONCACHED_MEMORY setting. Boards can set this to the size to be used for the non-cached area. The area will typically be right below the malloc() area, but architectures should take care of aligning the beginning and end of the area to honor any mapping restrictions. Architectures must also ensure that mappings established for this area do not overlap with the malloc() area (which should remain cached for improved performance). While the API is currently only implemented for ARM v7, it should be generic enough to allow other architectures to implement it as well.

* dm: Split the simple malloc() implementation into its own fileSimon Glass2014-11-21-1/+2
| | | | | | | | | | | | | | | | | | | | The simple malloc() implementation is used when memory is tight. It provides a simple buffer with an incrementing pointer. At present the implementation is inside dlmalloc. Move it into its own file so that it is easier to find. Rather than using relocation as a signal that the full malloc() is available, add a special GD_FLG_FULL_MALLOC_INIT flag. This signals that the simple malloc() should no longer be used. In some cases, such as SPL, even the code space used by the full malloc() is wasteful. Add a CONFIG_SYS_MALLOC_SIMPLE option to provide only the simple malloc. In this case the full malloc is not available at all. It saves about 1KB of code space and about 0.5KB of data on Thumb 2.
