[PATCH v2] armv8: u-boot-spl.lds: Place binman symbols at end of binary

[Jonas Karlman]

It can be useful in xPL to access symbols from binman, such as the
offset/position and size of a binman entry.

Place these binman symbols together at the end of the xPL binary for
ARMv8, similar to ARM and RISC-V.

Would you please disclose more details? What it will be used for?

Thanks,

The binman symbols can be used to get offsets of images in the binman
generated output, see [1] for U-Boot documentation and [2] for a feature
beside current normal usage of u-boot-img symbols in SPL.

Today the binman symbols will be spread out for ARMv8 SPL, this patch
concentrate the binman symbols to the end of the binary image, similar
to how it is handled for ARMv7 and RISC-V.
