ecause there is no check which symbol address is used to calculate end of image address. So, let's fix it and take ELF end of image address by reading __end_of_image__ symbol address from nm output. This way xen ELF image build process is not prone to changes in order of nm output. Signed-off-by: Daniel

[Xen-devel] [PATCH v9 06/13] efi: create new early memory allocator

because it is quite simple and requires limited number of changes, especially in __start_xen(). New allocator is quite generic and can be used on ARM platforms too. Though it is not enabled on ARM yet due to lack of some prereq. List of them is placed before ebmalloc code. Signed-off-by: Daniel
