what is 'boota' in uboot env? (1 reply)

I'm looking at the envs in my uboot and here it is:

baudrate=115200                                                                 
bootargs=console=ttymxc0,115200 init=/init video=mxcfb0:dev=hdmi,1920x1080M@60,M
bootcmd=boota mmc1                                                              
bootdelay=3                                                                     
ethact=FEC                                                                      
ethaddr=00:04:9f:03:ef:39                                                       
ethprime=FEC                                                                    
fastboot_dev=mmc1                                                               
fdt_high=0xffffffff                                                             
initrd_high=0xffffffff                                                          
loadaddr=0x12000000                                                             
splashpos=m,m

I don't understand what "bootcmd" values mean. Especially what is 'boota'? I've searched on google and it doesn't give me any meaningful results.

Another question that i have, is that once uboot executes bootcmd, does it automatically execute a kernel initiaing command with 'bootargs' by itself?
