According to https://wikidevi.wi-cat.ru/MediaTek#xPON, the older (mips based) MT752x chips are apparently just rebranded to EN752x after the business unit was spun off, but I guess they are still in the same family. > diff --git a/arch/arm/Makefile b/arch/arm/Makefile > index 173da685a52e..1bff0aa29c07 100644 > --- a/arch/arm/Makefile > +++ b/arch/arm/Makefile > @@ -152,6 +152,7 @@ textofs-$(CONFIG_ARCH_MSM8X60) := 0x00208000 > textofs-$(CONFIG_ARCH_MSM8960) := 0x00208000 > textofs-$(CONFIG_ARCH_MESON) := 0x00208000 > textofs-$(CONFIG_ARCH_AXXIA) := 0x00308000 > +textofs-$(CONFIG_ARCH_ECONET) := 0x00088000 Why is this needed? Note also the comment directly above it exlaining # Text offset. This list is sorted numerically by address in order to # provide a means to avoid/resolve conflicts in multi-arch kernels. Arnd
