Rasmus Villemoes <ravi@prevas.dk> says: There's really no reason for the gd pointer to have the volatile qualifier. In fact, I claim that it's completely unnecessary and just pessimizes code generation and forces ugly casts in lots of places. For example, see the casts in drivers/core/tag.c where elements are added to gd->dm_taglist, or a helper such as cyclic_get_list() that should not be needed. Also, it is what ends up standing in the way of an otherwise innocent code cleanup of list.h: https://lore.kernel.org/u-boot/20250522165656.GB2179216@bill-the-cat/ Note that riscv, x86 as well as arm64 with LTO enabled has not had this volatile qualifier, so it's unlikely there's any generic code that depends on it.
