| |
From: Oleksandr Andrushchenko <oleksandr_andrushchenko@epam.com>
Building for a 32-bit target results in warnings from casting between a 32-bit pointer and a 64-bit integer. Fix the warnings by casting those pointers to uintptr_t first.
Signed-off-by: Oleksandr Andrushchenko <oleksandr_andrushchenko@epam.com> --- Changes since v1: - remove unneeded u64 and phys_addr_t casts (Juergen)
