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>
2018-04-06common: env_embedded: allow fine placement of environment objectChristophe Leroy
Commit 7653942b10e9e ("common/env_embedded.c: drop support for CONFIG_SYS_USE_PPCENV") dropped the .ppcenv section which was used in linking scripts to allow fine placement of embedded environment sections. This implies that GCC randomly places objects from env/embedded.o and environment is not guaranteed to be located at the correct address: 04003df8 g F .text 00000038 mii_init 04004000 g O .text 00000004 env_size 04004004 g O .text 00002000 environment 04006004 g F .text 00000040 .hidden __lshrdi3 This patch restores this capability by allocating each object marked with __UBOOT_ENV_SECTION__ into a different section. Hence 'environment' will be alone in .text.environment, allowing a fine placement in u-boot.lds with: . = DEFINED(env_offset) ? env_offset : .; env/embedded.o (.text.environment) Fixes: 7653942b10e9e ("common/env_embedded.c: drop support for CONFIG_SYS_USE_PPCENV") Cc: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>
2017-08-15Move environment files from common/ to env/Simon Glass
About a quarter of the files in common/ relate to the environment. It seems better to put these into their own subdirectory and remove the prefix. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>
