MX6DQ and MX6DL share the common board file, but only MX6DQ has built-in
SATA, for the SATA PDDQ should be enabled default, so it needs to add
code to distinguish different chip ID.

After using POR reset, the content in SRC will be reset.
See RM: 63.5.1.2.3 IPP_RESET_B(POR)
Because POR reset will reset most of register in IC, so use
SNVS_LP General Purpose Register (LPGPR) to store the boot mode value.
Below copy from SNVS_BlockGuide.pdf:
The SNVS_LP General Purpose Register provides a 32 bit read write
register, which can be used by any application for retaining 32 bit
data during a power-down mode
This Patch will use [7,8] bits of this register.

Add generic gpio interface in uboot.
Seems more and more gpio operation invoke in uboot,
without RAW register operation, we should
use generic gpio interface.
you should define the CONFIG_MXC_GPIO
use generic gpio interface:
gpio_request,
gpio_direction_output,
gpio_direction_input,
gpio_set_value,
gpio_get_value, etc.
Test on MX6Q, MX6DL.
Other MX6X should also define this config.

Original pad configuration don't provide enough bitfield width to hold
all necessary information. For MX6Sololite, a "PAD_CTL_LVE" is needed
to be configed for many pins.
iomux_v3_cfg_t is re-orgnized to address this issue. PAD_CTRL is
extended by 1 bit to hold the "PAD_CTL_LVE". Which is mapped to proper
bit location when configure the PAD config register.

The first stage of High Assurance Boot (HAB) is the authentication of
U-boot. A CST tool is used to generate the CSF data, which include
public key, certificate and instruction of authentication process. Then
it is attached to the original u-boot.bin
The IVT should be modified to contain a pointer to the CSF data. The original
u-boot.bin is with size between 0x27000 to 0x28000. For convinence, we first
extend the u-boot.bin to 0x2F000 (with fill 0xFF). Then concatenate it with
the CSF data. The combined image is again extend to a fixed length (0x31000),
which is used as the IVT size parameter.
The new memory layout is as the following.
U-Boot Image
+-------------+
| Blank |
|-------------| 0x400
| IVT |-----------------------+
|-------------| |
| | |
| | |
| | |
|Remaining UB | | CSF pointer
| | |
| | |
| | |
|-------------| |
| | |
| Fill Data | |
| | |
|-------------| 0x2F000 <-------------+
| |
| CSF Data |
| |
|-------------|
| |
| Fill Data |
| |
+-------------+ 0x31000
HAB APIs are ROM implemented, the entry table is located in a fixed
location in the ROM. We export them so that during the HAB we can
have some information about the secure boot process. For convinience
some wrapper API is implemented based on the HAB APIs.
- get_hab_status : used to dump information of authentication result
- authenticate_image : used by u-boot to authenticate uImage
For security hardware to function, CAAM related clock (CG0[4~6]) must
be open. They are default closed in the original U-boot.
"hab_caam_clock_enable" and "hab_caam_clock_disable" are created to
open and close these clock gates.
The generation of CSF data is not in the scope of this patch. CST tool
will be used for this purpose. The procedure will be introduced in
another document.

Add support for MX6Q ARM2 LPDDR2 POP CPU Board. Change thing include
- TEXT_BASE
- RAM address and size
- Initialization DCD
- MMU related code
Use mx6q_arm2_lpddr2pop_config as the build config. After u-boot.bin is
generated, set the board to serial download mode, use sb loader to run the
bootloader.
There is one line in the original DDR initialization script
setmem /32 0x00B00000 = 0x1
however this address can not be accessed by DCD. A try to add it later in
"dram_init" block the boot up. Waiting for IC team to give an explanation
on it. Hold temperorily
The MMU Change can be concluded as the following
- Cacheable and Uncacheable SDRAM allocation changes to
Phys Virtual Size Property
---------- ---------- -------- ----------
0x10000000 0x10000000 256M cacheable
0x80000000 0x20000000 16M uncacheable
0x81000000 0x21000000 240M cacheable
- TEXT_BASE change to 0x10800000, which reserves 8MB of memory at the start
of SDRAM. This address makes sure that the text section of U-boot have the
same Physical and Virtural address, thus the PC don't need to change when
MMU is enabled. Also the text section is all allocated in cacheable memory,
which may increase excecution performance.
- Since this SDRAM allocation avoid overlap in physical memory between
cacheable and uncacheable memory, the implementation of __ioremap can be
ignored

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.

On SD3 on MX50, there is an option to choose eSDHC or uSDHC controller.
By default eSDHC is selected. However, eSDHC shows some borderline timing
in SDR mode at 50 MHz, whereas uSDHC shows borderline timing in DDR mode
at 50 MHz. Therefore, add a compile time option to uboot for MX50 to
select uSDHC in SDR mode or eSDHC in DDR mode on SD3 port.
By default the compile time option, CONFIG_MX50_ENABLE_USDHC_SDR,
is commented out in the include/configs/mx50_<board>.h file to
select eSDHC with DDR mode enabled. Uncomment the define to select
uSDHC with only SDR mode enabled.
Also increased max frequency supported by ESDHC to 52 MHz instead
of 50 MHz.
