uboot usage examples

script 0x1000000				- simple run from addr 0x1000000
script 0x1000000 32 			- same but only fist 32 bytes
script 0x1000000 $filesize 			- same but limited by file size value 
script 0x1000000 $filesize nochk 		- same but without $!script header check
script 0x1000000 $filesize nochk silent	- same but silent

# tftp script usage
ADDR=0x1000000; tftp $ADDR test.script && script $ADDR $filesize 

# usage as files
ADDR=100000; ext4load mmc 1:5 $ADDR dhcp.cmd_test.script; script $ADDR $filesize

# spi flash usage
ADDR=100000; sf read $ADDR $SCRIPT_OFFSET $SCRIPT_BYTES; script $ADDR
