Pass the table address as a paramter to the build function and cause it to return the number of entries. Pass both base and offset as parameters to the dump function. This adds a duplicated e820.h header to ROMBIOS. Since the e820 data structure is well defined by existing BIOS implementations I think this is OK and simplifies the cross talk between hvmloader and ROMBIOS. Reduces the cross talk between ROMBIOS and hvmloader. Signed-off-by: Ian Campbell <ian.campbell@citrix.com> Acked-by: Keir Fraser <keir@xen.org>
