> Octeontx2 PMD's mailbox client uses device memory to send messages to
> mailbox server in the admin function Linux kernel driver.
> The device memory used for the mailbox communication needs to be
> qualified as volatile memory type to avoid unaligned device memory
> accesses because of compiler's memory access coalescing.
>
> This patch modifies the mailbox request and responses as volatile type which
> were non-volatile earlier and accessed from unaligned memory addresses.
