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

[trini: Drop ip04 and pm9263 configs/ additions, those boards previously
 set CONFIG_AUTOBOOT_PROMPT but never used it, re-run savedefconfig over
 all boards that did change. Make digsy_mtc_* string include seconds to
 match others and not warn. ]

Commit 8183058188cd2d942 ("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.

There are two revisions of wandboard: version B1 and C1.

Add the revision detection support, so that the correct dtb file can
be automatically loaded.

Based on the patch from Richard Hu <hakahu@gmail.com>.
