Booting Options
---------------
a) Promjet Boot
b) NOR boot
c) NAND boot
d) SD boot
e) QSPI boot

Environment Variables
---------------------
- mcboottimeout: MC boot timeout in milliseconds. If this variable is not defined
  the value CONFIG_SYS_LS_MC_BOOT_TIMEOUT_MS will be assumed.

- mcmemsize: MC DRAM block size. If this variable is not defined
  the value CONFIG_SYS_LS_MC_DRAM_BLOCK_MIN_SIZE will be assumed.

Booting Linux flavors which do not support 48-bit VA (< Linux 3.18)
-------------------------------------------------------------------
One needs to use appropriate bootargs to boot Linux flavors which do
not support 48-bit VA (for e.g. < Linux 3.18) by appending mem=2048M, as shown
below:

=> setenv bootargs 'console=ttyS1,115200 root=/dev/ram
   earlycon=uart8250,mmio,0x21c0600,115200 default_hugepagesz=2m hugepagesz=2m
   hugepages=16 mem=2048M'
