hwconfig=fsl_ddr:ctlr_intlv=null,bank_intlv=cs0_cs1;usb1:
dr_mode=host,phy_type=utmi
Note: For USB gadget set "dr_mode=peripheral"

2. FMAN Ucode versions
fsl_fman_ucode_t1040.bin

3. Switching to alternate bank
Commands for switching to alternate bank.

1. To change from vbank0 to vbank4
=> cpld reset altbank (it will boot using vbank4)

2.To change from vbank4 to vbank0
=> cpld reset (it will boot using vbank0)

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

PBL-based image generation
==========================
Changes only the required register bit in in PBI commands.

Provides reference code which might needs some
modification as per requirement.
example:
By default PBI_SRC=14 (which is for IFC-NAND/NOR) in rcw.cfg file
which needs to be changed for SPI and SD.

For SD-boot
==============
1. Set RCW[192:195], PBI_SRC bits as 6 in RCW file (t1040d4_rcw.cfg type files)

example:
RCW file: board/freescale/t104xrdb/t1040d4_rcw.cfg

Change
66000002 40000002 ec027000 01000000
to
66000002 40000002 6c027000 01000000

2. SD does not support flush so remove flush from pbl, make changes in
tools/pblimage.c file, Update value of pbl_end_cmd[0] = 0x09138000
with 0x091380c0

For SPI-boot
==============
1. Set RCW[192:195], PBI_SRC bits as 5 in RCW file (t1040d4_rcw.cfg type files)

example:
RCW file: board/freescale/t104xrdb/t1040d4_rcw.cfg

Change
66000002 40000002 ec027000 01000000
to
66000002 40000002 5c027000 01000000

2. SPI does not support flush so remove flush from pbl, make changes in
tools/pblimage.c file, Update value of pbl_end_cmd[0] = 0x09138000
with 0x091380c0
