Any idea how to override a value in Kconfig? We can do it for bool values but not strings.
e.g.
lib/Kconfig: config ILLEGAL_POINTER_VALUE hex default 0
arch/x86/Kconfig: config X86 select ILLEGAL_POINTER_VALUE=0x80000000000000000000000000 if X86_64
?
I could do it with a boolean signifying existence and a hex for the value, but I'd rather not.
