When passing Kernel arguments, is it necassary to populate the bootargs environment variable with 
the information found by using command , bdinfo - print Board Info structure 
=> help bdinfo
bdinfo - No help available.
The bdinfo command (short: bdi) prints the information that U-Boot passes information about the board like memory addresses and sizes, clock frequencies, MAC address etc. This information is mainly needed to be passed to the Linux kernel. 
=> bdi
memstart    = 0x00000000
memsize     = 0x04000000
flashstart  = 0x40000000
flashsize   = 0x00800000
flashoffset = 0x00030000
sramstart   = 0x00000000
sramsize    = 0x00000000
immr_base   = 0xFFF00000
bootflags   = 0x00000001
intfreq     =     50 MHz
busfreq     =     50 MHz
ethaddr     = 00:D0:93:00:28:81
IP addr     =
baudrate    = 115200 bps

If I want these to be passed to the Linux kernel?
