2019-09-03riscv: tools: Handle addend to absolute reloc in prelink-riscvMarcus Comstedt1-2/+6
Previously the handling of R_RISCV_32 and R_RISCV_64 would simply insert the value of the symbol and ignore any addend. However, there exist relocs where the addend is non-zero: 0000000080250900 R_RISCV_64 efi_runtime_services+0x0000000000000068 0000000080250910 R_RISCV_64 efi_runtime_services+0x0000000000000038 0000000080250920 R_RISCV_64 efi_runtime_services+0x0000000000000018 0000000080250930 R_RISCV_64 efi_runtime_services+0x0000000000000020 0000000080250980 R_RISCV_64 efi_runtime_services+0x0000000000000048 0000000080250990 R_RISCV_64 efi_runtime_services+0x0000000000000050 00000000802509a0 R_RISCV_64 efi_runtime_services+0x0000000000000058 0000000080250940 R_RISCV_64 systab+0x0000000000000030 0000000080250950 R_RISCV_64 systab+0x0000000000000040 0000000080250960 R_RISCV_64 systab+0x0000000000000050 0000000080250970 R_RISCV_64 systab+0x0000000000000060 In these cases the addend needs to be added to the symbol value to get the correct value for the reloc.

2019-08-15riscv: tools: Fix prelink-riscv to work on big endian hostsMarcus Comstedt1-20/+22
All ELF fields whose values are inspected by the code are converted to CPU byteorder first. Values which are copied verbatim (relocation fixups) are not swapped to CPU byteorder and back as it is not needed.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
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>
2018-01-12riscv: tools: Prelink u-bootRick Chen1-0/+112
Add prelink-riscv to arrange .rela.dyn and .rela.got in compile time. So that u-boot can be directly executed without fixup.
