The method for invoking an ELF-based image (as well as any tables that must be set up to allow it to boot) will always depend on the specific architecture. core/elf.c now only provides the elf_load() function, to avoid duplicating functionality between ELF-based image types. Add arch/i386/image/elfboot.c, to handle the generic case of 32-bit x86 ELF images. We don't currently set up any multiboot tables, ELF notes, etc. This seems to be sufficient for loading kernels generated using both wraplinux and coreboot's mkelfImage. Note that while Etherboot 5.4 allowed ELF images to return, we don't. There is no callback mechanism for the loaded image to shut down gPXE, which means that we have to shut down before invoking the image. This means that we lose device state, protection against being trampled on, etc. It is not safe to continue afterwards. Replace image->entry with image->priv. 2007-01-14T04:04:28+00:00 Michael Brown 2007-01-14T04:04:28+00:00 urn:sha1:797edf28b7e2f0f6fe374bbe230e68b2ab05cbdc Force probing of multiboot before ELF. 2007-01-12T08:10:35+00:00 Michael Brown 2007-01-12T08:10:35+00:00 urn:sha1:6fdc6c81a6a089074d17f46b0ab930e6e1445e8b Rename copy_user() to memcpy_user().

Use setting image->type to disambiguate between "not my image" and "bad image"; this avoids relying on specific values of the error code.
