These two symbols come from Linux asm files that have been simply copied over to U-Boot, they are not configuration options in U-Boot. They are used by both CPU_V7M and others. Perhaps I have misunderstood, but for non-CPU_V7M, since CONFIG_THUMB2_KERNEL depends on CONFIG_SYS_THUMB_BUILD, are you asking me to add Kconfig for CONFIG_SYS_THUMB_BUILD?
