#| Relocation address. Set this to the linear address where you want your code
#| to start. It should abide to the following constraints:
#| RELOCADDR >= 0x10200
#| RELOCADDR + 'image file size' < 0xA0000
#| RELOCADDR % 4 = 0 (i.e. aligned on a 4 byte boundary)
#| Set the value of RELOCADDR to the address where you want your image to
#| load. If you'll be using GRUB to load the images it will have to be >=
#| 0x100000 (1024K). If you are using NetBoot to load the images it can be
#| >= 0x10000 (64K) AND <= 0x97C00 (607K) OR >= 0x100000 (1024K). The memory
#| top is of course another limit. Make sure there is enough space before the
#| upper memory limits for the image and the memory allocated by it to fit.
#| Make sure the value you choose is aligned to 4 bytes.
