* src/fs/fileio.c (do_list): Use getcwd for current directory, rather than "." which may not be implemented in the FS. * src/parse.c (redboot_exec): Conditionalise use of __mem_fault_handler to only be when stubs are included. (error_handler): Ditto for this function. * src/main.c (cyg_start): Conditionalise use of __mem_fault_handler to only be when stubs are included. (do_go): Ditto. (error_handler): Ditto for this function. * src/fs/fileio.c (do_mkdir, do_deldir, do_del, do_write): Added some extra argument checking to these functions. * src/fs/fileio.c (do_mount): Only support -f with "legacy" flash block devices. Clear mount table on failure. (do_move): Silence rename undefined warning. (do_write): Silence warnings. (do_info): Support longer device names. * src/decompress.c (ZLIB_COMPRESSION_OVERHEAD): Increase substantially if jffs2 is present. * src/fs/fileio.c: Fixed some bugs in handling of mounts. The strings used in the mount table must be copied, otherwise the mount table is corrupted by later commands. Also toughened up some error testing. * doc/redboot_cmds.sgml: Added file mode documentation to load command. * doc/redboot_cmds.sgml: Added documentation of filesystem access commands. * src/fs/fileio.c (do_write): Added O_TRUNC to the open call to ensure that the file is resized to fit the new data. * src/fs/fileio.c: Significantly reorganized to present an interface similar to the fis commands. Added a variety of command to manipulate files and directories in a filesystem. * src/parse.c: Added redboot_exec() to provide an internal interface for executing RedBoot commands. Added err_printf() which allows an error message to be printed before longjumping out to an enclosing call to redboot_exec(). Where redboot_exec() is not involved, it just behaves like diag_printf(). * src/main.c: Removed unnecessary delay during startup. Changed diag_printf() in do_go() into err_printf(). * src/load.c: Changed some calls to diag_printf() to err_printf(). * src/net/net_io.c: Changed init priority to RedBoot_INIT_NET. * include/redboot.h: Added some extra initialization priorities. Added prototypes for redboot_exec() and err_printf().
