2018-07-25ARM: uniphier: enable distro bootMasahiro Yamada
Switch to the distro boot for UniPhier platform. - Remove the environment vairalbes used to load images from raw block devices. - Keep the command to download images via tftp. This will be useful to boot the kernel when no valid kernel image is ready yet in the file system. - Use root.cpio.gz instead of root.cpio.uboot because we always know the file size of the init ramdisk; it is loaded via either a file system or network. - Rename fit_addr_r to kernel_addr_r, which the distro command checks to get the load address of FIT image.

2018-07-24avb2.0: add proper dependenciesIgor Opaniuk
1. Since libavb library alone is highly portable, introduce dedicated Kconfig symbol for AVB bootloader-dependent operations, so it's possible to build libavb separately. AVB bootloader-dependent operations include: * Helpers to process strings in order to build OS bootargs. * Helpers to access MMC, similar to drivers/fastboot/fb_mmc.c. * Helpers to alloc/init/free avb ops. 2. Add CONFIG_FASTBOOT dependency, as fastboot buffer is re-used in partition verification operations.

2018-07-23doc: Replace DocBook with sphinx-based docsMario Six
The Linux kernel moved to sphinx-based documentation and got rid of the DocBook based documentation quite a while ago. Hence, the DocBook documentation for U-Boot should be converted as well. To achieve this, import the necessary files from Linux v4.17, and convert the current DocBook documentation (three files altogether) to sphinx/reStructuredText. For now, all old DocBook documentation was merged into a single handbook, tentatively named "U-Boot Hacker Manual". For some source files, the documentation style was changed to comply with kernel-doc; no functional changes were applied. Signed-off-by: Mario Six <mario.six@gdsys.cc>

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>
