* src/fconfig.c, src/flash.c, src/io.c, src/load.c, src/main.c, src/xyzModem.c, include/redboot.h: more signed vs. unsigned char issues. * src/fs/e2fs.c (e2fs_mount): Avoid compiler strict aliasing problem. * include/fis.h (struct fis_image_desc): Make fis name be signed char to reduce warnings. * include/flash_config.h (struct _config): Make config_data be signed char to reduce warnings. * include/redboot.h: mon_write_char and mon_read_char_with_timeout take unsigned char, to reduce warnings. * src/parse.c: Add const to err_printf format. * src/fconfig.c: Many signed/unsigned warning cleanups. * src/io.c: Ditto. * src/xyzModem.c: Ditto. * src/load.c: Ditto. * src/flash.c: Ditto. * src/fconfig.c (flash_write_config): Warning cleanup. * src/net/net_io.c (do_ip_addr): Warning cleanup. * src/flash.c (fis_create): Warning cleanup. * include/net/net.h: Include redboot.h for tick functions. * include/net/net.h: Pull tick functions into redboot.h as they are used more widely than the net stack. * include/redboot.h: Declare tick functions. * src/main.c (cyg_start): Correctly compute workspace_end so it works even on high RAM values [bug #1000202]. Don't use workspace_end directly for context init - it gets modified. (do_go): Don't use workspace_end directly for context init - it gets modified.
