gigabyte m57sli-s4 and linuxBIOS: now easier

I checked in some code to add support for the m57sli-s4 to buildrom, the LinuxBIOS kconfig-style configuration tool that allows easy building of rom images. FILO and linux-as-a-bootloader (LAB – i.e. a linux kernel + busybox in the ROM chip) are now supported via buildrom, and the build tutorial has been updated to reflect this change.

Using buildrom makes building a ROM image very simple – it’s a matter of doing

make menuconfig

and then selecting the relevant options, followed by

make

The major obstacle for this board remains the hardware – some soldering is required, and the newer revisions of the board have a new kind of ROM chip that flashrom can not handle yet. But we’re going to work on that.
