I do not like this much. This platform is ARCH_MULTI_V7. ARM_PATCH_PHYS_VIRT allows you to place the kernel image anywhere in memory as long as the base is aligned at 16MB. The minimum 'textofs-y := 0x0008000' + extra 16MB offset will create a space (0x00000000 ~ 0x01008000). This is more than needed, but it is not a big deal to waste some megabytes of memory. -- Best Regards Masahiro Yamada
