From: Pankaj Bansal <pankaj.ban...@nxp.com> The BBTestAllocatePagesInterfaceTest tries to allocate pages for different memory types. While doing so, it tries to fix up the Start and PageNum for 64K Page size. There are multiple issues with this:
1. 64K alignment is being done regardless of Processor type and Memory type. while this is correct for ARM64 Processor, it might not be so for other Processor types. Also 64K alignment for ARM64 Processor is needed for some Memory types not all. 2. The Start is being incremented by 64K, even if Start is already 64K aligned. 3. PageNum is being decreased by 16 pages indiscriminately, which might not be needed in all cases. fix all these issues by correctly doing the alignment in all needed cases.
