From 4ddb1bf1a83783cebdb174b0efaf62f63ad64e0b Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 23 Nov 2022 14:21:16 +0100 Subject: [PATCH] tegra: mark BPMP driver as little-endian only The BPMP firmware driver never worked on big-endian kernels, and cannot easily be made portable. Add a dependency to make this clear in case anyone ever wants to try a big-endian kernel on this hardware.
