Hi,
This short (although not small) patchset adds a fix for the PCIE SerDes
link problems when using x4/x2 end points. Because it relies
on the boot time HW configuration of the reference clock,
a new library is introduced for obtaining sample at reset configuration.
Later it will be reused e.g. in the SMBIOS driver.
More details can be found in the commit log. The code is also
available in the github:
https://github.com/MarvellEmbeddedProcessors/edk2-open-platform/commits/x4pcie-upstream-r20180216
I'm looking forward to your feedback.
Best regards,
Marcin

From: Igal Liberman <igall@marvell.com>
The sample at reset library adds the following functionalities:
- MvSARGetCpuFreq - Get the CPU frequency
- MvSARGetDramFreq - Get the DRAM frequency
- MvSARGetPcieClkDirection - Determine the PCIe clock direction
for two types specified in CP110 HW block. It will be needed
for proper configuration during the PCIE SerDes training.

From: Evan Wang <xswang@marvell.com>
PCIE clock direction (input/output) has implications on comphy settings.
There are 2 PCIe clocks in CP110:
- Ref clock 0 for lanes 1,2 and 3
- Ref clock 1 for lanes 4 and 5
A proper handling of above had to be added, using newly introduced
sample at reset library class for Marvell SoCs.
Other than that, update HPIPE settings and the reset sequence,
which differ from one used in x1 link.
This patch fixes PCIE x4 and x2 configuration, which helps
to overcome link establishing issue for multi-lane end points.

Please add an explanation of what a SAR is.
Since it appears to be a specific thing referred to under that name,
it is correct to use the abbreviation throughout, but it needs to be
introduced.
Similarly, from coding standards, section 4.1.3.2
---
Any abbreviation used, which is not documented in this specification,
or in the UEFI Specification shall be placed into a Glossary section
of the File header as specified in See "File Heading".
---
(search for "File Heading" in
https://edk2-docs.gitbooks.io/edk-ii-c-coding-standards-specification/content/v/release/2.20/5_source_files/52_spacing.html)
I would appreciate if you could include this in .c and .h files of
this patch.

Missing parantheses in macro.
If CP and AP are also common terms used in documentation for this
component, please add it to the glossary (but not commit message).

Are these not just derivatives of each other?
I.e. CP0_PCIE0_CLK_MASK is the same as (1 << CP0_PCIE0_CLK_OFFSET)?
If so, can they be defined as such?

TianoCore coding style suggests name should be CLOCKING_OPTIONS.
And that
Also, I would prefer to see all of the above definitions broken out

I don't object to _having_ _OFFSET definitions, but to expand them on
each use is just noisy.
Please (for all of these) add something like
