Add workaround for POR/wdog reset issue, we need to
do a CORE LDO reset everytime POR/wdog reset, otherwise
kernel will crash or hang when we booting more than 2
cores. Root cause is still under investigation, it is
analog/power related issue, may take long time to
identify the root cause, we need to add workaround to make
function ready first. The flow of workaround is as below:
1. Check CORE LDO reset flag, currently stored in SNVS_LPGPR[0];
2. If it is there, clear it, go on boot up system; If not,
Set the flag, configure wdog to timeout in 0.5 seconds, then
disable CORE LDO and wait for wdog timeout;
This workaround will bring 0.5~1 seconds delay of booting.

Add "download_mode" command to U-Boot. It will force a system reset and let
boot running in "boot from serial rom" mode, which can be used by manufacturing
tool.
The command will triggle a write to SRC_GPR9 and SRC_GPR10, then triggle a
watchdog reset. GPR9 and GPR10 can maintain their value during the reset, the
value in it make ROM to start in "boot from serial rom" mode. After that GPR9
and GPR10 are written by their original value for normal boot.

1. This patch is used to switch back to use DCD for flash header
instead of plug-in. This change request is due to the following
reasons:
1) U-boot community doesn't accept current plug-in solution when
upstreaming.
2) Plug-in isn't supported by MX53 ROM serial download mode.
No effective workaround is found now. To use the same code
base to support normal U-Boot and MFG tool better, adopt
DCD solution firstly.
3) Current MX53 DDR scripts don't exceed the length limitation
of DCD.
For MX53 TO2.0 EVK/ARM2 board, raise DDR frequency to 400MHZ after
VCC and VDDA voltages are raised as 1.3V.
Since ARM2 CPU2 board share the same script with EVK, delete ARM2
CPU2 config files. ARM2 CPU2 board can share the same bootloader
with EVK.
2. Update MX53 DDR2 scripts for TO1.0/TO2.0 EVK/ARD/ARM2 boards
The script "MX53_TO2_DDR2_EVK_ARD.inc" is located under
http://compass.freescale.net/livelink/livelink?
func=ll&objId=221058910&objAction=browse&viewType=1
This script is published by ATX and FIL team on Dec 16th, 2010
3. Update MX53 ARM2 CPU3 DDR3 script "MX53_TO2_DDR3_CPU3.inc"
under the same compass folder

Support new DDR script entitled
"Rita_TO2_init_DDR2_CPU2_CMOS_TEST_CAL_v1.inc" for DDR2
boards including MX53 EVK, ARD, and ARM2 CPU2. These new settings
did not apply to TO1. Therefore, changed the DCD
for these boards to a plugin so that TO1 and TO2 can both
be supported using conditional execution of new DDR settings.
During bootup on TO2, DDR frequency is required to be below
400 MHz. Therefore, BOOT_CFG2[4] must be set to enable DDR at
333 MHz in ROM on all boards. Uboot determines silicon version
and for TO2 boosts the VCC and VDDA voltages to 1.3V, after
which the DDR frequency is also increased to 400 MHz.
This requirement meant that uboot does not calibrate PLL2
anymore until the voltage is increased. Removed the calibration
from lowlevel_init.S and from all mx53 include/configs files.
Also required that during config_periph_clk(), only CBCMR register
is touched to set source PLL. Other changes to CBCDR were removed.
Switching to PLL2 bypass clk during reprogram was also removed.
All these changes are required to increase DDR frequency to 400 MHz.
DDR2 CPU2 board with TO1 requires the following hw cfgs:
JP3 populated, and J8 set to 2-3.
For DDR2 CPU2 board with TO2, both these jumpers should be
depopulated.
ARM2 CPU3 (with DDR3) DDR configurations were not changed.
TO1 and TO2 can run well using existing DDR3 script. However,
DCD was converted to plugin to align with other boards.

MT29F16G08MAA NAND flash was failed on MX53 ARD/RevB
board, but it's fine in RevA board. After check, it's
found that udelay is not accurate on MX53 ARD/RevB
board because GPT uses IPG peripheral clock and assume it
is 50MHZ. However IPG peripheral clock is not 50MHZ in
MX53 ARD/RevB board. So it causes udelay is not accurate.
This patch changes GPT clk source as 32K to make udelay
accurate.

Add NAND support for MX53 EVK and ARD.
Need to use kobs-ng to flash U-Boot on MX53 TO1. Because
MX51 TO1 ROM doesn't support bi swap solution and kernel
enable bi swap, Must enable "ignore bad block" option when
flashing U-Boot. The step is as following:
echo 1 > /sys/devices/platform/mxc_nandv2_flash.0/ignorebad
kobs-ng init --chip_0_device_path=/dev/mtd2 u-boot.bin
echo 0 > /sys/devices/platform/mxc_nandv2_flash.0/ignorebad
Since default configuration stores environment into SD
card and U-Boot uses get_mmc_env_devno (Read SBMR register)
to get MMC/SD slot information, you must insert SD card to
bottom SD slot to get/store environment if you are using NAND
boot on MX53 EVK.
You must config boot dip setting well when doing NAND boot.
For example, if you are using NAND 29F32G080AA NAND chip on
MX53 EVK, you can set boot dips as the following for NAND
boot: SW3: dip 7, 8 on; SW2: dip 3,5 on; SW1: dip 4,7,8 on.
Other dips are off.
