[makefile] Split platform-dependent portions out of arch/i386/Makefile

[romprefix] Add .mrom format, allowing loading of large ROMs Add an infrastructure allowing the prefix to provide an open_payload() method for obtaining out-of-band access to the whole iPXE image. Add a mechanism within this infrastructure that allows raw access to the expansion ROM BAR by temporarily borrowing an address from a suitable memory BAR on the same PCI card. For cards that have a memory BAR that is at least as large as their expansion ROM BAR, this allows large iPXE ROMs to be supported even on systems where PMM fails, or where option ROM space pressure makes it impossible to use PMM shrinking. The BIOS sees only a stub ROM of approximately 3kB in size; the remainder (which can be well over 64kB) is loaded only at the time iPXE is invoked. As a nice side-effect, an iPXE .mrom image will continue to work even if its PMM-allocated areas are overwritten between initialisation and invocation. Signed-off-by: Michael Brown <mcb30@ipxe.org>

[pxeprefix] Add .kkpxe image type and ability to return via PXE stack Certain combinations of PXE stack and BIOS result in a broken INT 18 call, which will leave the system displaying a "PRESS ANY KEY TO REBOOT" message instead of proceeding to the next boot device. On these systems, returning via the PXE stack is the only way to continue to the next boot device. Returning via the PXE stack works only if we haven't already blown away the PXE base code in pxeprefix.S. In most circumstances, we do want to blow away the PXE base code. Base memory is a limited resource, and it is desirable to reclaim as much as possible. When we perform an iSCSI boot, we need to place the iBFT above the 512kB mark, because otherwise it may not be detected by the loaded OS; this may not be possible if the PXE base code is still occupying that memory. Introduce a new prefix type .kkpxe which will preserve both the PXE base code and the UNDI driver (as compared to .kpxe, which preserves the UNDI driver but uninstalls the PXE base code). This prefix type can be used on systems that are known to experience the specific problem of INT 18 being broken, or in builds (such as gpxelinux.0) for which it is particularly important to know that returning to the BIOS will work. Written by H. Peter Anvin <hpa@zytor.com> and Stefan Hajnoczi <stefanha@gmail.com>, minor structural alterations by Michael Brown <mcb30@etherboot.org>.

[build] Fix broken build caused by implied dependency upon "perl" Commit ea12dc0 ("[build] Avoid hard-coding the path to perl") introduced a build failure for fully clean trees (e.g. after running "make veryclean"), since the dependency upon $(PARSEROM) now includes a dependency upon "perl" (which doesn't exist) rather than upon "/usr/bin/perl" (which does exist). There should of course be no dependency upon the perl binary at all; the dependency should be upon "./util/parserom.pl" alone. Fix by removing the $(PERL) from the definition of Perl-based utility paths, and adding $(PERL) at the point of usage.

[build] Replace obsolete makerom.pl with quick script using Option::ROM The only remaining useful function of makerom.pl is to correct the ROM and PnP checksums; the PCI IDs are set at link time, and padding is performed using padimg.pl. Option::ROM already provides a facility for correcting the checksums, so we may as well just use this instead. Signed-off-by: Michael Brown <mcb30@ipxe.org>
