Subject: [PATCH 19/26] pci: mpc85xx: Support controller register physical address beyond 32-bit
Date: Sun, 7 Feb 2021 23:11:19 +0800 [thread overview]
Message-ID: <1612710687-56493-20-git-send-email-bmeng.cn@gmail.com> (raw)
In-Reply-To: <1612710687-56493-1-git-send-email-bmeng.cn@gmail.com>
devfdt_get_addr_index() returns fdt_addr_t which might be a 64-bit
physical address. Use map_physmem() to return the virtual address
that can be used by a 32-bit machine.
