This updates the sizes of the preallocated regions so that the number
of distinct regions that exists is minimal at the time we exit boot
services.
For a typical run of the ArmVirtQemu platform, we get the following
utilization numbers:
Reserved : 4 Pages (16,384 Bytes)
LoaderCode: 210 Pages (860,160 Bytes)
LoaderData: 0 Pages (0 Bytes)
BS_Code : 355 Pages (1,454,080 Bytes)
BS_Data : 6,807 Pages (27,881,472 Bytes)
RT_Code : 112 Pages (458,752 Bytes)
RT_Data : 288 Pages (1,179,648 Bytes)
ACPI_Recl : 32 Pages (131,072 Bytes)
ACPI_NVS : 0 Pages (0 Bytes)
MMIO : 16,385 Pages (67,112,960 Bytes)
MMIO_Port : 0 Pages (0 Bytes)
PalCode : 0 Pages (0 Bytes)
Available : 123,264 Pages (504,889,344 Bytes)
--------------
Total Memory: 511 MB (536,854,528 Bytes)
Strangely enough, the allocation count of 20,000 pages for BS_Data
does not result in those regions being merged. For BS_Code, RT_Code
and RT_Data, the increased preallocation results in the following
reduction in the number of regions.
