2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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>
2018-02-14configs: Migrate CONFIG_SPL_FRAMEWORKTom Rini
Migrate the option CONFIG_SPL_FRAMEWORK and make this gate most of the current set of options we have in Kconfig. We will need to have some options available for SPL and !SPL_FRAMEWORK so this is important. In a few cases we re-order existing options so that we have less escapes from the SPL_FRAMEWORK guard.

2017-02-07x86: link: Add build options for SPLSimon Glass
If SPL is used we want to use the generic SPL framework and boot from SPI via a board-specific means. Add these options to the board config file. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2015-04-29x86: Move CONFIG_ENV_IS_IN_SPI_FLASH to x86-common.hBin Meng
Since all x86 boards use spi flash as its bootloader storage media, it makes sense to make CONFIG_ENV_IS_IN_SPI_FLASH a common option. So far only minnowmax board does not support it so undefine it in its board configuration file. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>

2015-01-13x86: Make chromebook_link the default board for corebootBin Meng
Change SYS_CONFIG_NAME and DEFAULT_DEVICE_TREE to chromebook_link which is currently the only real board officially supported to run U-Boot loaded by coreboot. Note the symbolic link file chromebook_link.dts is deleted and link.dts is renamed to chromebook_link.dts. To avoid multiple definition of video_hw_init, the CONFIG_VIDEO_X86 define needs to be moved to arch/x86/cpu/ivybridge/Kconfig.

2014-11-21x86: ivybridge: Implement SDRAM initSimon Glass
Implement SDRAM init using the Memory Reference Code (mrc.bin) provided in the board directory and the SDRAM SPD information in the device tree. This also needs the Intel Management Engine (me.bin) to work. Binary blobs everywhere: so far we have MRC, ME and microcode. SDRAM init works by setting up various parameters and calling the MRC. This in turn does some sort of magic to work out how much memory there is and the timing parameters to use. It also sets up the DRAM controllers. When the MRC returns, we use the information it provides to map out the available memory in U-Boot. U-Boot normally moves itself to the top of RAM. On x86 the RAM is not generally contiguous, and anyway some RAM may be above 4GB which doesn't work in 32-bit mode. So we relocate to the top of the largest block of RAM we can find below 4GB. Memory above 4GB is accessible with special functions (see physmem). It would be possible to build U-Boot in 64-bit mode but this wouldn't necessarily provide any more memory, since the largest block is often below 4GB. Anyway U-Boot doesn't need huge amounts of memory - even a very large ramdisk seldom exceeds 100-200MB. U-Boot has support for booting 64-bit kernels directly so this does not pose a limitation in that area. Also there are probably parts of U-Boot that will not work correctly in 64-bit mode. The MRC is one. There is some work remaining in this area. Since memory init is very slow (over 500ms) it is possible to save the parameters in SPI flash to speed it up next time. Suspend/resume support is not fully implemented, or at least it is not efficient. With this patch, link boots to a prompt. Signed-off-by: Simon Glass <sjg@chromium.org>

2014-11-21x86: Build a .rom file which can be flashed to an x86 machineSimon Glass
On x86 machines U-Boot needs to be added to a large ROM image which is then flashed onto the target board. The ROM has a particular format so it makes sense for U-Boot to build this image automatically. Unfortunately it relies on binary blobs so we cannot require this for the default build as yet. Create a u-boot.rom output file for this purpose. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-11-21x86: Add chromebook_link boardSimon Glass
This board is a 'bare' version of the existing 'link 'board. It does not require coreboot to run, but is intended to start directly from the reset vector. This initial commit has place holders for a wide range of features. These will be added in follow-on patches and series. So far it cannot be booted as there is no ROM image produced, but it does build without errors. Signed-off-by: Simon Glass <sjg@chromium.org>
