@Thomas. I see your point. I'll merge them into my repo with Baikal-T1 CSP/BSP
patches and will deliver all at once when the kernel is ready to accept the
changes (most likely in 3 - 5 months).

@Jiaxun, if you've any hardware which for sure supports the strong UC
ordering, feel free to submit a patchset which activates the proposed here
config together with my STRONG_UC_ORDERING-alteration applied before your
changes.
