With the current timeout of 1000 cycles of 100 microsecond would see
timeout occurs on OCP Delta Lake if the log level is set to values
smaller than 8. Because the prink(BIOS_SPEW, ..) in ipmi_kcs_status()
creates delay and avoid the problem, but after setting the log level
to 4 we see some timeout occurs.
The unit is millisecond and the default value is set to 5000 according
to IPMI spec v2.0 rev 1.1 Sec. 9.15, a five-second timeout or greater
is recommended.
Tested=On OCP Delta Lake, with log level 4 cannot observe timeout

This ports Linux commit 71f677a91046599ece96ebab21df956ce909c456
"Handle configuration without P2A bridge".
Quote:
The ast driver configures a window to enable access into BMC
memory space in order to read some configuration registers.
If this window is disabled, which it can be from the BMC side,
the ast driver can't function.
Closing this window is a necessity for security if a machine's
host side and BMC side are controlled by different parties;
i.e. a cloud provider offering machines "bare metal".
P2A stands for primary to AHB.
Tested on Prodrive Hermes, which uses an AST2500. The machine still
boots, has a high resolution framebuffer working in EDK2, and its
boot time has been reduced by 2.5 seconds as it no longer runs into
a timeout due to disabled P2A bridge.

Create two new functions to fetch mrc_cache data (replacing
mrc_cache_get_current):
- mrc_cache_load_current: fetches the mrc_cache data and drops it into
the given buffer. This is useful for ARM platforms where the mmap
operation is very expensive.
- mrc_cache_mmap_leak: fetch the mrc_cache data and puts it into a
given buffer. This is useful for platforms where the mmap operation
is a no-op (like x86 platforms). As the name mentions, we are not
freeing the memory that we allocated with the mmap, so it is the
caller's responsibility to do so.
Additionally, we are replacing mrc_cache_latest with
mrc_cache_get_latest_slot_info, which does not check the validity of
the data when retrieving the current mrc_cache slot. This allows the
caller some flexibility in deciding where they want the mrc_cache data
stored (either in an mmaped region or at a given address).

the CAR region, since AMD Picasso doesn't support CAR and the DRAM is
already available when the x86 cores are released from reset. Selecting
FSP_USES_CB_STACK ended up doing the right thing, but is semantically

This change updates the mipi_camera driver to handle shared power
resource between multiple cameras. This is achieved by adding a guard
variable and methods to manipulate the guard variable before calling
the actual platform method which enables or disables the resource.
PowerResource will call these guarded methods to enable or disable the
resource. This protects the shared resource from being enabled or
disabled multiple times while the other camera is using the resource.
Example:
Consider a platform where two cameras are sharing a GPIO resource 0xXX
and both the cameras calls enable and disable guarded methods for this
GPIO. Actual platform disable method for the GPIO is called only after
the last camera using the GPIO calls DSBx method and RESx becomes 0.
