annotate packages/redboot/current/src/fs/fileio.c @ 1724:549e69d9a7d0

* cdl/redboot.cdl: * src/net/net_io.c: added CDL to allow the default server to be configured. Also respect the CYGSEM_REDBOOT_DEFAULT_NO_BOOTP setting. * cdl/redboot.cdl: * src/load.c: Added cdl to control the size of the buffer used by getc. The size can have significant affect on load speed when loading from a filesystem. * cdl/redboot.cdl * src/load.c (load_elf_image): Added a CDL option to configure if the physical or virtual address in the headers should be used when loading the image. * cdl/redboot.cdl * src/fs/fileio.c (do_ls) Added an ls command so we can see what is inside the mounted filesystem.
