ARC: Use elf32-bigarc in case of -EB

2018-05-31T17:13:29Z

As it is stated in LD manual [1] the second entry in OUTPUT_FORMAT corresponds to "-EB" command-line option which for us is "elf32-bigarc". [1] https://sourceware.org/binutils/docs/ld/Format-Commands.html#Format-Commands Signed-off-by: Alexey Brodkin

ARC: Move .ivt section to the very beginning of the image

2018-05-31T17:13:29Z

This is useful for cases when U-Boot image is put in ROM and reset vector points to 0 where the very beginnign of the image reside. Signed-off-by: Alexey Brodkin

ARC: Make sure .ivt section is not purged by garbage collector

2018-05-31T17:13:29Z

Fixes commit fac4790491f6 ("arc: Eliminate unused code and data with GCC's garbage collector"), see [1]. Since in case of ARCv2 .ivt only contains addrresses of interrupt/exception handlers linker doesn't understand that this section actually make a lot of sense and decides to get rid of it if we use "--gc-sections". And KEEP does exactly this, see [2].

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

2018-05-07T13:34:12Z

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

arc: No need in sections defined in sources with newer tools

2016-08-05T09:50:25Z

Starting from arc-2016.03 GNU tools linker properly works with symbols defined in linker script and so external declarations are no longer required, dump them. Signed-off-by: Alexey Brodkin

arc: make sure _start is in the beginning of .text section

2015-04-10T15:45:34Z

This is important to have entry point in the beginning of .text section because it allows simple loading and execution of U-Boot. For example pre-bootloader loads U-Boot in memory starting from offset 0x81000000 and then just jumps to the same address. Otherwise pre-bootloader would need to find-out where entry-point is. In its turn if it deals with binary image of U-Boot there's no way for pre-bootloader to get required value. Signed-off-by: Alexey Brodkin

arc: move linker script in arch/arc/cpu folder

2015-01-15T19:40:44Z

This way we'll be able to use the same one script for either ARC CPU. Signed-off-by: Alexey Brodkin
