From: Heinrich Schuchardt Date: Fri, 10 Apr 2020 09:10:32 +0000 (+0200) Subject: Makefile: ARMv7-M has no CPSR register X-Git-Tag: v2020.10~268^2~14 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0053d26bcc09fc4473572d51a9c754a409ffd562;p=platform%2Fkernel%2Fu-boot.git Makefile: ARMv7-M has no CPSR register Compiling on ARMv7-M fails when trying to address the CPSR register which is not available on this architecture. Atomic functions refer to the CPSR register if compiled with arch/arm/include/asm/proc-armv/system.h. On ARMv7-M we should hence use arch/arm/thumb1/include/asm/proc-armv/system.h instead.
