* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-071-2/+1
| | | | | | | | | | | | | | | | | | | | When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
* Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTRTom Rini2018-04-271-2/+0
| | | | | | | | We have a large number of places where while we historically referenced gd in the code we no longer do, as well as cases where the code added that line "just in case" during development and never dropped it. Signed-off-by: Tom Rini <trini@konsulko.com>
* env: Rename getenv/_f() to env_get()Simon Glass2017-08-161-1/+1
| | | | | | | | | | | We are now using an env_ prefix for environment functions. Rename these two functions for consistency. Also add function comments in common.h. Quite a few places use getenv() in a condition context, provoking a warning from checkpatch. These are fixed up in this patch also.

* Move console definitions into a new console.h fileSimon Glass2015-11-191-0/+1

* update: tftp: dfu: Extend update_tftp() function to support DFULukasz Majewski2015-09-071-1/+1
| | | | | | | | | | | | | | | This code allows using DFU defined mediums for storing data received via TFTP protocol. It reuses and preserves functionality of legacy code at common/update.c. The update_tftp() function now accepts parameters - namely medium device name and its number (e.g. mmc 1). Without this information passed old behavior is preserved.

* fdt: allow bootdelay to be specified via device treeStephen Warren2013-06-041-0/+5
| | | | | | | | | | | | | | | | This can be useful to force bootcmd to execute as soon as U-Boot has started. My use-case is: An SoC-specific tool pushes U-Boot into RAM, along with an image to be written to device boot flash, with the DT config property "bootcmd" set to contain a command to write that image to flash. In this scenario, we don't want to allow any stale bootdelay value taken from the current flash content to affect how long it takes before the flashing process starts.

* main: Separate out the two abortboot() functionsSimon Glass2013-06-041-8/+11
| | | | | | | | | | | | | There are two implementations of abortboot(). Turn these into two separate functions, and create a single abortboot() which calls either one or the other. Also it seems that nothing uses abortboot() outside main, so make it static. At this point there is no further use of CONFIG_MENU in main.c.

* CONFIG_BOOTDELAY default should not affect runtimeJoe Hershberger2013-03-121-8/+6

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If kernel-offset is specified in the fdt, set an environment variable so that scripts can access the attached kernel. This can be used by a packaging program to tell U-Boot about a kernel that has been downloaded alongside U-Boot. The value in the fdt is the offset of the kernel from the start of the U-Boot image, so we can find it just by adding CONFIG_SYS_TEXT_BASE. It is then fairly easy to put something like this in the environment variables in the board header file: "if test ${kernaddr} != \"\"; then "\ "echo \"Using bundled kernel\"; "\ "bootm ${kernaddr};" \ "fi; "\ /* rest of boot sequence follows here */ Signed-off-by: Simon Glass <sjg@chromium.org>
