Currently the standalonemmlibinternal assumes the max physical bits to be 36 which is causing issues on v8 architectures. Instead use the MAX_ALLOC_ADDRESS macro to determine the maximum allowed address rather than recomputing it locally.

Internal ARCH Specific file of MM memory check library.
|
|
|
|
MM memory check library implementation. This library consumes MM_ACCESS_PROTOCOL
|
|
to get MMRAM information. In order to use this library instance, the platform should produce
|
|
all MMRAM range via MM_ACCESS_PROTOCOL, including the range for firmware (like MM Core
|
|
and MM driver) and/or specific dedicated hardware.
