B4860 Overview
-------------
The B4860 QorIQ Qonverge device is a Freescale high-end, multicore SoC based on
-StarCore and Power Architecture® cores. It targets the broadband wireless
+StarCore and Power Architecture® cores. It targets the broadband wireless
infrastructure and builds upon the proven success of the existing multicore
DSPs and Power CPUs. It is designed to bolster the rapidly changing and
expanding wireless markets, such as 3GLTE (FDD and TDD), LTE-Advanced, and UMTS.
B4420 Personality
--------------------
B4420 is a reduced personality of B4860 with less core/clusters(both SC3900 and e6500), less DDR
-controllers, less serdes lanes, less SGMII interfaces and reduced target frequencies.
+controllers, less serdes lanes, less SGMII interfaces and reduced target frequencies.
Key differences between B4860 and B4420
----------------------------------------
-
+
B4420 has:
1. Less e6500 cores: 1 cluster with 2 e6500 cores
2. Less SC3900 cores/clusters: 1 cluster with 2 SC3900 cores per cluster.

3. Switching to alternate bank
Commands for switching to alternate bank.
- 1. To change from vbank0 to vbank2
+ 1. To change from vbank0 to vbank2
=> qixis_reset altbank (it will boot using vbank2)
2.To change from vbank2 to vbank0
1)Boot from vbank0
2)Flash vbank2 with b4420 rcw and u-boot
3)Give following commands to uboot prompt

+NAND boot with 2 Stage boot loader
+----------------------------------
+PBL initialise the internal SRAM and copy SPL(160KB) in SRAM.
+SPL further initialise DDR using SPD and environment variables and copy
+u-boot(768 KB) from flash to DDR.
+Finally SPL transer control to u-boot for futher booting.
+
+SPL has following features:
+ - Executes within 256K
+ - No relocation required
+
+ Run time view of SPL framework during boot :-
