ARM: don't use --gc-sections with LTO when using private libgcc

2021-05-24T18:21:30+00:00

When using LTO, we can throw away the --gc-sections flag, but only if using private libgcc. When using system's libgcc, --gc-sections is still needed, otherwise linking will fail due to undefined references to libc's symbols. Signed-off-by: Marek Behún Reviewed-by: Simon Glass

ARM: don't use -ffunction-sections/-fdata-sections with LTO build

Makefile: Rename ALL-y to INPUTS-y

2020-07-29T01:30:39+00:00

When binman is in use, most of the targets built by the Makefile are inputs to binman. We then need a final rule to run binman to produce the final outputs. Rename the variable to indicate this, and add a new 'inputs' target. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

efi_loader: Rename sections to allow for implicit data

2018-07-25T12:57:44+00:00

Some times gcc may generate data that is then used within code that may be part of an efi runtime section. That data could be jump tables, constants or strings. In order to make sure we catch these, we need to ensure that gcc emits them into a section that we can relocate together with all the other efi runtime bits. This only works if the -ffunction-sections and -fdata-sections flags are passed and the efi runtime functions are in a section that starts with ".text". Up to now we had all efi runtime bits in sections that did not interfere with the normal section naming scheme, but this forces us to do so. Hence we need to move the efi_loader text/data/rodata sections before the global *(.text*) catch-all section. With this patch in place, we should hopefully have an easier time to extend the efi runtime functionality in the future. Signed-off-by: Alexander Graf [agraf: Fix x86_64 breakage]

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

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

clang: Update documentation

2018-04-27T18:54:49+00:00

As of clang-5.0, things have changed a bit. First, we cannot automatically guess -target values as if we do not pass one with CC then cc-option will fail. Second, to disable movt/movw relocations the argument has become -mno-movt. Related to the target part, we cannot use arm-none-eabi as that ends up being too generic of an ARM target for things like say rpi_3_32b to work. Signed-off-by: Tom Rini

binman: arm: Include the binman symbol table
