I think we should start from the beginning with support for multiple variants of the processor. I know there will be at least i.MX8 and i.MX8M, but I suppose that I am not well informed and many variants will come, exactly as we had with i.MX6. So we need a hierarchy: first the SOC family, then the SOC variant: MX8 and MX8M (or whatever). But in the patches, it is not clear because ARCH = SOC = M8M. Which variants are already known ? As far as I can see, at least Quad, QuadMax and QuadPlus. > config ARCH_MX25 > bool "NXP MX25" > select CPU_ARM926EJS > @@ -1157,6 +1163,8 @@ source "arch/arm/cpu/armv7/ls102xa/Kconfig" > > source "arch/arm/mach-imx/mx2/Kconfig" > > +source "arch/arm/mach-imx/mx8m/Kconfig" > + > source "arch/arm/mach-imx/mx7ulp/Kconfig" > > source "arch/arm/mach-imx/mx7/Kconfig" > diff --git a/arch/arm/Makefile b/arch/arm/Makefile > index 5f1caf8f86..4db0398dde 100644 > --- a/arch/arm/Makefile > +++ b/arch/arm/Makefile > @@ -95,11 +95,11 @@ libs-y += arch/arm/cpu/ > libs-y += arch/arm/lib/ > > ifeq ($(CONFIG_SPL_BUILD),y) > -ifneq (,$(CONFIG_MX23)$(CONFIG_MX28)$(CONFIG_MX35)$(filter $(SOC), mx25 mx5 > mx6 mx7 mx35)) > +ifneq (,$(CONFIG_MX23)$(CONFIG_MX28)$(CONFIG_MX35)$(filter $(SOC), mx25 mx5 > mx6 mx7 mx35 mx8m)) > libs-y += arch/arm/mach-imx/ > endif > else > -ifneq (,$(filter $(SOC), mx25 mx27 mx5 mx6 mx7 mx7ulp mx31 mx35 mxs vf610)) > +ifneq (,$(filter $(SOC), mx25 mx27 mx5 mx6 mx7 mx7ulp mx31 mx35 mxs mx8m > vf610)) > libs-y += arch/arm/mach-imx/ > endif > endif > diff --git a/arch/arm/mach-imx/mx8m/Kconfig b/arch/arm/mach-imx/mx8m/Kconfig > new file mode 100644 > index 0000000000..3a84c2f2b0 > --- /dev/null > +++ b/arch/arm/mach-imx/mx8m/Kconfig > @@ -0,0 +1,10 @@ > +if ARCH_MX8M > + > +config MX8M > + bool > + select ROM_UNIFIED_SECTIONS > + > +config SYS_SOC > + default "mx8m" > + > +endif > Best regards, Stefano -- ===================================================================== DENX Software Engineering GmbH, Managing Director: Wolfgang Denk HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: +49-8142-66989-53 Fax: +49-8142-66989-80 Email: sba...@denx.de ===================================================================== _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
