o Use a directory layout that is more akin to the i386 boot layout. o Create a libat91 for library routines that are used by one or more of the boot loaders. o Create bootiic for booting from an iic part. o Create bootspi for booting from an spi part. o Optimize the size of many of these routines (especially emac.c). Except for the emac.c optimizations, all these have been tested. o eliminate the inc directory, libat91 superceeds it. o Move linker.cfg up a layer to allow it to be shared.
