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
Device tree support and how to enable it for different configs
--------------------------------------------------------------
Device tree support is available for t1042d4rdb for below mentioned boot,
1. NOR Boot
2. NAND Boot
3. SD Boot
4. SPIFLASH Boot
To enable device tree support for other boot, below configs need to be
enabled in relative defconfig file,
1. CONFIG_DEFAULT_DEVICE_TREE="t1042d4rdb" (Change default device tree name if required)
2. CONFIG_OF_CONTROL
3. CONFIG_MPC85XX_HAVE_RESET_VECTOR if reset vector is located at
CONFIG_RESET_VECTOR_ADDRESS - 0xffc
If device tree support is enabled in defconfig,
1. use 'u-boot-with-dtb.bin' for NOR boot.
2. use 'u-boot-with-spl-pbl.bin' for other boot.
