From fc76324fa27fa4cab2cf115460d3a1d8e7e201ee Mon Sep 17 00:00:00 2001 From: Olof Johansson Date: Mon, 6 Jan 2020 15:20:24 -0800 Subject: [PATCH] riscv: keep 32-bit kernel to 32-bit phys_addr_t While rv32 technically has 34-bit physical addresses, no current platforms use it and it's likely to shake out driver bugs. Let's keep 64-bit phys_addr_t off on 32-bit builds until one shows up, since other work will be needed to make such a system useful anyway. PHYS_ADDR_T_64BIT is def_bool 64BIT, so just remove the select.
