Some older compilers have no implementation for the helper for 64-bit unsigned division/modulo, so linking pcie-brcmstb driver causes the "undefined reference to `__aeabi_uldivmod'" error. *rc_bar2_size is always a power of two, because it is calculated as: "1ULL << fls64(entry->res->end - entry->res->start)", so the modulo operation in the subsequent check can be replaced by a simple logical AND with a proper mask.
