Newly added cm_t335 was missed in commit 47ed5dd0 which
made ARM targets produce full ELF files. Fix its linker
script.
This change is binary-invariant when only .dynsym, .dynstr,
.dynamic, .plt, .interp and .gun sections are declared.
Sections .hash, .got.plt, .dynbss and .ARM.exidx are also
declared so that their (unused) content is moved out of the
u-boot binary.

This prevents references to _end from generating absolute
relocation records.
This change is binary invariant for ARM targets.

From: Albert ARIBAUD @ 2014-01-08 8:57 UTC (permalink / raw)
To: u-boot
Remove the last uses of symbol offsets in ARM U-Boot.
Remove some needless uses of _TEXT_BASE.
Remove all _TEXT_BASE definitions.
Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>

To: u-boot
Newly added cm_t335 was missed in commit 47ed5dd0 which
made ARM targets produce full ELF files. Fix its linker
script.
This change is binary-invariant when only .dynsym, .dynstr,
.dynamic, .plt, .interp and .gun sections are declared.
Sections .hash, .got.plt, .dynbss and .ARM.exidx are also
declared so that their (unused) content is moved out of the
u-boot binary.

This prevents references to _end from generating absolute
relocation records.
This change is binary invariant for ARM targets.

Changes in v5: None
Changes in v4:
- removed mkexynosspl patch, already fixed in 0fcac1ab
Changes in v3: None
Changes in v2:
- fixed use of _rel_dyn_end instead of _end

That's a mistake of mine; they should not have been added back. Thanks
for spotting this, v6 under test right now.

Hi All,
For exynos5250 board we use CONFIG_SKIP_LOWLEVEL_INIT, hence change in
"board/samsung/smdk5250/lowlevel_init.S" should not effect. Infact I
feel that file can be removed.
Regards,
Rajeshwari

If so then please post a separate patch for this removal, which is
logically unrelated to removing symbol offsets.
