Timo Alho a4740b148a firmware: tegra: bpmp: Do only aligned access to IPC memory area
Use memcpy_toio and memcpy_fromio variants of memcpy to guarantee no
unaligned access to IPC memory area. This is to allow the IPC memory to
be mapped as Device memory to further suppress speculative reads from
happening within the 64 kB memory area above the IPC memory when 64 kB
memory pages are used.
