[PATCH v1] configs: socfpga: stratix10: Disable mkeficapsule tool build

[NG, BOON KHAI]

Hi Tom,

Thank you for the clarification and for looping in the EFI Loader custodians.

I'm okay with the implementation to improve the Kconfig logic to only enable
`CONFIG_TOOLS_MKEFICAPSULE` by default on platforms that actually support
EFI capsule updates would be the best long-term solution.
This would prevent misleading configurations and avoid unnecessary
build failures on platforms that do not use the tool.

I'm happy to help test or review any proposed changes in this area.

In the meantime, could we set the setting

+# CONFIG_TOOLS_MKEFICAPSULE is not set 

at the defonfig first? as I believe disabling the tool
explicitly in the SoCFPGA defconfig remains the most
accurate way to reflect the board's capabilities and
avoid confusion for users.

Thanks again for the constructive discussion.

Regards,
Boon Khai
