Subject: [RFT PATCH v3 3/5] riscv: Separate memory init from paging init
Date: Fri, 18 Sep 2020 13:11:38 -0700 [thread overview]
Message-ID: <20200918201140.3172284-4-atish.patra@wdc.com> (raw)
In-Reply-To: <20200918201140.3172284-1-atish.patra@wdc.com>
Currently, we perform some memory init functions in paging init. But,
that will be an issue for NUMA support where DT needs to be flattened
before numa initialization and memblock_present can only be called
after numa initialization.
Move memory initialization related functions to a separate function.
