[U-Boot] [PATCH v1 0/1] Get rid of R_ARM_ABS32 relocation records

R_ARM_ABS32 relocation records cause symbol references
to be zero before relocation, and become correct only
after relocation. On the other hand, R_ARM_RELATIVE
records make references correct before as well as
after relocation.

This patch series aims at removing all R_ARM_ABS32
relocations from ARM targets.

the main contributor of R_ARM_ABS32 relocations is the
support code for linker-lists, aka Linker-Generated
Arrays. This is due to the fact that LGA start and end
symbols, used for ranging these arrays, are linker-
generated symbols, which always relocate as R_ARM_ABS32
even though they are supposed *not* to be absolute.

V1 of this patch 'series' fixes LGAs so that start or
end symbols are actually compiler-generated, and thus
their references are relocated using R_ARM_RELATIVE.

This V1 is provided for all to test and make sure that
no ill-effect arises from LGA changes; V2 will integrate
any feedback on LGAs and also remove any remaining
R_ARM_ABS32 relocations.
