[PATCH v1 0/2] Cleanup i.MX95 based Toradex boards

[Stefan Eichenberger]

This series removes two leftovers from the Toradex i.MX95 board support.

The first patch drops CONFIG_SPI from the aquila-imx95, verdin-imx95 and
toradex-smarc-imx95 defconfigs. It has been set since the initial board
support, but none of the boards selects an SPI controller or slave
driver, so SPI is not usable in U-Boot on them anyway.

The second patch removes the WDOG_BASE_ADDR definition from
verdin-imx95.h. The ULP watchdog driver takes its base address from the
devicetree now, and the macro it expanded to no longer exists, so the
definition is dangling.

Neither patch changes behaviour, they only drop unused configuration.
All three boards were build tested.

[PATCH v1 1/2] configs: {aquila, verdin, toradex-smarc}-imx95: remove CONFIG_SPI

[Stefan Eichenberger]

From: Stefan Eichenberger <stefan.eichenberger@toradex.com>

CONFIG_SPI=y has been set on the Toradex i.MX95 boards since their
initial board support commits, but none of them selects an SPI
controller or slave driver. The option therefore only builds the SPI
uclass with no bus behind it, and SPI is not usable in U-Boot on these
boards.

Remove CONFIG_SPI from the aquila-imx95, toradex-smarc-imx95 and
verdin-imx95 defconfigs to reduce maintenance effort. No other symbol
selects SPI, so the resulting configuration ends up with
"# CONFIG_SPI is not set".

[PATCH v1 2/2] imx: verdin-imx95: remove unused WDOG_BASE_ADDR

[Stefan Eichenberger]

From: Stefan Eichenberger <stefan.eichenberger@toradex.com>

The ULP watchdog driver obtains its base address from the devicetree
since commit 3cacd1b1809d ("watchdog: ulp_wdog: Use driver model for
reset_cpu()"), so WDOG_BASE_ADDR has no user left. Commit 4f8d6c8f417c
("imx: Remove hardcoded watchdog base address macros") dropped the macro
from the other i.MX9 boards, including toradex-smarc-imx95, but missed
verdin-imx95.

The definition is in fact dangling: WDG3_BASE_ADDR was removed from
arch-imx9/imx-regs.h by that same commit, so anything expanding
WDOG_BASE_ADDR would now fail to build.

Remove the leftover definition.

Fixes: 4f8d6c8f417c ("imx: Remove hardcoded watchdog base address macros")
