[PATCH v2 0/3] add Toradex Verdin iMX95 support

[Emanuele Ghidoli]

From: Emanuele Ghidoli <emanuele.ghidoli at toradex.com>

This series adds initial U-Boot support for the Toradex Verdin iMX95.

It also introduces a new RAM-size probing helper based on alias checks.
On Verdin iMX95, the first DDR region is reserved for Cortex-M7 firmware and
the get_ram_size() could not be used to detect the actual RAM size.
Using explicit probe/alias pairs provides reliable size detection for the
supported memory variants.

The board DT is currently aligned with linux-next. Once the board DTS is
in mainline Linux, we'll move to OF_UPSTREAM.

v2:
 - add check for CONFIG_IS_ENABLED(SYS_DCACHE_OFF) in probe_ram_size_by_alias
 - renamed ram_alias_check variable to ram_alias_checks. Added static qualifier.
 - fixed typo in verdin-imx95.h: determited -> determined

v1: https://lore.kernel.org/u-boot/20260416084535.1490476-1-ghidoliemanuele@gmail.com/
