That is the minimum size required by a platform, and happens to be the value 
used by the edk2. It is defined in the calling convention section (2.3.*) of 
the UEFI spec. 

The EFI Stack size is currently hard coded in the DXE IPL PEIM. 

https://svn.code.sf.net/p/edk2/code/trunk/edk2/MdeModulePkg/Core/DxeIplPeim/DxeIpl.h
#define STACK_SIZE      0x20000

Thanks,
