Rename CONFIG_SYS_TEXT_BASE to CONFIG_TEXT_BASE 2022-10-31T15:01:31+00:00 Simon Glass sjg@chromium.org 2022-10-21T00:22:39+00:00 984639039f4cfe32ec2cc531d6ace05326ac49eb The current name is inconsistent with SPL which uses CONFIG_SPL_TEXT_BASE and this makes it imposible to use CONFIG_VAL(). Rename it to resolve this problem. Signed-off-by: Simon Glass <sjg@chromium.org>

microblaze: Add support for run time relocation 2022-06-24T12:15:01+00:00 Michal Simek michal.simek@amd.com 2022-06-24T12:15:01+00:00 d58c007498258b73d9eb5e3b24973578498fc341 Microblaze is using NEEDS_MANUAL_RELOC from the beginnging. This is causing issues with function pointer arrays which need to be updated manually after relocation. Building code with -fPIC and linking with -pic will remove this limitation and there is no longer need to run manual update. By default still old option is enabled but by disabling NEEDS_MANUAL_RELOC code will be compiled for full relocation. The patch does couple of things which are connected to each other. - Define STATIC_RELA dependency to call relocate-rela to fill sections. - REMAKE_ELF was already enabled but u-boot file can't be used because sections are empty. relocate-rela will fill them and output file is u-boot.elf which should be used. - Add support for full relocation (u-boot.elf) - Add support for early relocation when u-boot.bin is loaded to different address then CONFIG_SYS_TEXT_BASE - Add rela.dyn and dynsym sections Disabling NEEDS_MANUAL_RELOC U-Boot size increased by 10% of it's original size (550kB to 608kB).

Microblaze is using NEEDS_MANUAL_RELOC from the beginnging. This is causing
issues with function pointer arrays which need to be updated manually after
relocation. Building code with -fPIC and linking with -pic will remove this
limitation and there is no longer need to run manual update.

By default still old option is enabled but by disabling NEEDS_MANUAL_RELOC
code will be compiled for full relocation.

The patch does couple of things which are connected to each other.
- Define STATIC_RELA dependency to call relocate-rela to fill sections.
- REMAKE_ELF was already enabled but u-boot file can't be used because
  sections are empty. relocate-rela will fill them and output file is
  u-boot.elf which should be used.
- Add support for full relocation (u-boot.elf)
- Add support for early relocation when u-boot.bin is loaded to different
  address then CONFIG_SYS_TEXT_BASE
- Add rela.dyn and dynsym sections

Disabling NEEDS_MANUAL_RELOC U-Boot size increased by 10% of it's original
size (550kB to 608kB).
