linker: Modify linker scripts to be more generic

2019-01-27T03:55:53Z

Make use of "IMAGE_MAX_SIZE" and "IMAGE_TEXT_BASE" rather than CONFIG_SPL_MAX_SIZE and CONFIG_SPL_TEXT_BASE. This lets us re-use the same script for both SPL and TPL. Add logic to scripts/Makefile.spl to pass in the right value when preprocessing the script.

MIPS: optimize and fix ELF sections

2019-01-16T12:56:43Z

Discard ABI related sections which are not required for debugging. Rearrange debug sections similar to Linux. Remove the remaining explicitely specified sections in the unused part because those sections are not created anymore or because the linker puts them by default at the end of the ELF binary.

MIPS: move create_tlb() in an proper header: mipsregs.h

2018-12-19T14:23:01Z

Export create_tlb() as an inline function in mipsregs.h. It allows to remove the declaration of the function from the board files. Then it will allow also to use this function very early in the boot when the stack is not usable. Signed-off-by: Gregory CLEMENT

MIPS: fix linking of standalone programs

2018-11-18T15:02:23Z

Use the global MIPS specific u-boot.lds for linking standalone programs instead of the outdated ones in examples/standalone/. Also pass --gc-sections in LDFLAGS_STANDALONE to optimize the size of standalone programs. Finally remove the deprecated config.mk files in arch/mips/cpu/mips[32,64]/.

Kbuild: add LDFLAGS_STANDALONE

2018-11-18T15:02:23Z

Introduce a new Makefile variable for passing LDFLAGS to standalone programs. Currently the variable CONFIG_STANDALONE_LOAD_ADDR is misued on some archs to pass a specific linker script. Signed-off-by: Daniel Schwierzeck Reviewed-by: Tom Rini Reviewed-by: Rick Chen

MIPS: make size of relocation table fixed but configurable

2018-11-02T21:39:07Z

Currently the size of the relocation table will be shrunk to the actual size needed. Although this gives a maximal space saving, it messes up the _end symbol. This breaks features like appended DTBs because the _end symbol doesn't point to the real end of the U-Boot binary. Remove the size shrinking and make the size of the relocation table fixed but configurable. This follows the Linux approach and the user can adjust the size to his needs. Also rename the relocation table section from .rel to .data.reloc to follow the Linux approach and to avoid ambiguities with the .rel.* sections added by the linker.

MIPS: start.S: make boot config at offset 0x10 configurable

2018-09-22T18:59:22Z

Some MIPS systems store some board-specific boot configuration in the U-Boot binary at offset 0x10. This is used by Malta boards and by Lantiq/Intel SoC's when booting from parallel NOR flash. Convert the hard-coded values to Kconfig options to remove such board-specific stuff out of the generic start.S code. This also deprecates the config option CONFIG_SYS_XWAY_EBU_BOOTCFG.

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

MIPS: Drop unused PTR_COUNT_SHIFT from u-boot.lds

2017-11-28T20:59:30Z

The u-boot.lds linker script for MIPS defines a PTR_COUNT_SHIFT macro to 2 or 3 for 32 bit or 64 bit builds respectively. This macro is never actually used though, so remove the dead code. Signed-off-by: Paul Burton Cc: Daniel Schwierzeck

mips: spl: configure SYS_MALLOC_F_LEN independently for SPL and full U-Boot

2017-07-27T12:59:03Z

Some platforms have very limited SRAM to run SPL code, so there may not be the same amount space for a malloc pool before relocation in the SPL stage as the normal U-Boot stage. Make SPL and (the full) U-Boot stage use independent SYS_MALLOC_F_LEN, so the size of pre-relocation malloc pool can be configured memory space independently.
