Hi Tom,

The following changes since commit 9805321dfdeb5225fe5c5e0721abf49c0875637e:

  Kconfig: Introduce CONFIG_WERROR (2025-03-13 14:23:11 -0600)

  arm64: Enable RW, RX and RO mappings for the relocated binary (2025-03-14 13:37:54 +0200)

This is identical to the v4 posted here [0] but with Andre's comments addressed.
I skipped sending a v5 since the number of recipients are large and most of the
patches were already reviewed.

The CI at https://source.denx.de/u-boot/custodians/u-boot-tpm/-/pipelines/25152
showed no issues.

Please pull!

----------------------------------------------------------------
Up to now we configure the entire memory space for U-Boot as RWX.
For modern architectures and security requirements, it's better to
map the memory properly.
This pull request adds basics support for mapping the U-Boot binary with
proper (RO, RW, RW^X) memory permissions on aarch64 right after we
relocate U-Boot in the top of DRAM.
It's worrth noting that the linker script annotations are only added for
the aarch64 architecture. We can, in the future, try to unify the linker --
at least for the architectures that have enough in common and expand this
