arm64: Add missing GD_FLG_SKIP_RELOC handling

2021-11-18T23:20:19Z

In case U-Boot enters relocation with GD_FLG_SKIP_RELOC, skip the relocation. The code still has to set up new_gd pointer and new stack pointer. Signed-off-by: Marek Vasut Cc: Simon Glass Cc: Tom Rini

arm64: Fix relocation of env_addr if POSITION_INDEPENDENT=y

2021-06-28T18:47:10Z

If both POSITION_INDEPENDENT and SYS_RELOC_GD_ENV_ADDR are enabled, wherever original env is placed anywhere, it should be relocated to the right address. Relocation offset gd->reloc_off is calculated with SYS_TEXT_BASE in setup_reloc() and env address gd->env_addr is relocated by the offset in initr_reloc_global_data(). gd->env_addr = (orig env) + gd->reloc_off = (orig env) + (gd->relocaddr - SYS_TEXT_BASE) However, SYS_TEXT_BASE isn't always runtime base address when POSITION_INDEPENDENT is enabled. So the relocated env_addr might point to wrong address. For example, if SYS_TEXT_BASE is zero, gd->env_addr is out of memory location and memory exception will occur. There is a difference between linked address such as SYS_TEXT_BASE and runtime base address. In _main, the difference is calculated as "run-vs-link" offset. The env_addr should also be added to the offset to fix the address. gd->env_addr = (orig env) + ("run-vs-link" offset) + gd->reloc_off = (orig env) + (SYS_TEXT_BASE - _start) + (gd->relocaddr - SYS_TEXT_BASE) = (orig env) + (gd->relocaddr - _start) Cc: Marek Vasut Signed-off-by: Kunihiko Hayashi Acked-by: Marek Vasut Tested-by: Marek Vasut

common: Drop asm/global_data.h from common header

2021-02-02T20:33:42Z

Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include at all, so remove that include. Signed-off-by: Simon Glass Signed-off-by: Tom Rini

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

ARMv8: get new GD address from gd->new_gd directly

2017-10-08T20:19:56Z

the new GD address is calculated via board data BD currently it require the new GD area locates below BD tightly, so a strict constraint is imposed on memory layout which maybe make special platform unpleasant. fix it by getting new GD address from gd->new_gd directly.

spl: make SPL and normal u-boot stage use independent SYS_MALLOC_F_LEN

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.

lib/asm-offsets - make GD_RELOCADDR, GD_RELOC_OFF & GD_START_ADDR_SP available for all architectures

2015-03-06T01:50:28Z

x86: Save the BIST value on reset

2014-11-21T06:24:10Z

The built in self test value is available in register eax on start-up. Save it so that it can be accessed later. Unfortunately we must wait until the global_data is available before we can do this, so there is a little bit of shuffling to keep it around. Signed-off-by: Simon Glass Reviewed-by: Bin Meng
