AM335x-based 'Gumstix Pepper' SBCs and variants use different types of
RAM (DDR2 vs DDR3 with DDR3 being the default). Detect the board type
by reading the factory-programmed EEPROM [1] and use this to select any
runtime boot options such as RAM type.

This patch adds the feature to only stop the autobooting, and therefor
boot into the U-Boot prompt, when the input string / password matches
a values that is encypted via a SHA256 hash and saved in the environment.
This feature is enabled by defined these config options:
CONFIG_AUTOBOOT_KEYED
CONFIG_AUTOBOOT_STOP_STR_SHA256

These defines for a 2nd autoboot stop and delay string are nearly unused. Only
sc3 defines CONFIG_AUTOBOOT_DELAY_STR2. And a patch to remove this most likely
unmaintained board is also posted to the list.
By removing these defines the code will become cleaner and moving the remaining
compile options to Kconfig will get easier.

I might have missed something, but I failed to use the escape char '\'
in strings. To pass a printf format string like "foo %d bar\n" via
Kconfig to the code.
Right now its not possible to use the escape character '\' in Kconfig
string values correctly to e.g. set this string value "test output\n".
The '\n' will be converted to 'n'.
The current implementation removes some of the '\' chars from the input
string in conf_set_sym_val(). Examples:
'\' -> ''
'\\' -> '\'
'\\\' -> '\'
'\\\\' -> '\\'
...
And then doubles the backslash chars in the output string in
sym_escape_string_value(). Example:
'\' -> '' -> ''
'\\' -> '\' -> '\\'
'\\\' -> '\' -> '\\'
'\\\\' -> '\\' -> '\\\\'
...
As you see in these examples, its impossible to generate a single '\'
charater in the output string as its needed for something like '\n'.
This patch now changes this behavior to not drop some backslashes in
conf_set_sym_val() and to not add new backslashes in the resulting
output string. Removing the function sym_escape_string_value()
completely as its not needed anymore.

Commit 8183058188 ("imx6: centralise common boot options in
mx6_common.h") broke boot on mx6sl and mx6sx by assuming that all mx6
SoCs use the same LOADADDR/SYS_TEXT_BASE range, which is not correct.
DDR on mx6sx/mx6sl starts at 0x80000000.
Adjust LOADADDR/SYS_TEXT_BASE to the proper values for mx6sx/mx6sl,
so that these SoCs can boot again.
Also, TQMA6 requires a custom CONFIG_SYS_TEXT_BASE value, so move
its setting prior to the inclusion of mx6_common.h.

Before device-tree, the device serial number used to be passed to the kernel
using ATAGs (on ARM). This is now deprecated and all the handover to the kernel
should now be done using device-tree. Thus, this passes the serial-number
property to the kernel using the serial-number property of the root node, as
expected by the kernel.
The serial number is a string that somewhat represents the device's serial
number. It might come from some form of storage (e.g. an eeprom) and be
programmed at factory-time by the manufacturer or come from identification
bits available in e.g. the SoC.

Before this commit the code for determining the disconnect threshold was
checking for sun4i or sun6i assuming that those where the exception and
that newer SoCs use a disconnect threshold of 2 like sun7i does.
But it turns out that newer SoCs actually use a disconnect threshold of 3
and sun5i and sun7i are the exceptions, so check for those instead.
Here are the settings from the various Allwinner SDK sources:
sun4i-a10: USBC_Phy_Write(usbc_no, 0x2a, 3, 2);
sun5i-a13: USBC_Phy_Write(usbc_no, 0x2a, 2, 2);
sun6i-a31: USBC_Phy_Write(usbc_no, 0x2a, 3, 2);
sun7i-a20: USBC_Phy_Write(usbc_no, 0x2a, 2, 2);
sun8i-a23: USBC_Phy_Write(usbc_no, 0x2a, 3, 2);
sun8i-h3: USBC_Phy_Write(usbc_no, 0x2a, 3, 2);
sun9i-a80: USBC_Phy_Write(usbc_no, 0x2a, 3, 2);
Note this commit makes no functional changes for sun4i - sun7i, and
changes the disconnect threshold for sun8i to match what Allwinner uses.
