Merge https://gitlab.denx.de/u-boot/custodians/u-boot-x86WIP/06Feb2021
- introduces some standard sysinfo options as a source, e.g. to read strapping pins to determine the board revision - allows the U-Boot version number to be included - allows the version number to be provided programmatically, e.g. to support the build system adding information after U-Boot is built

+Version information
+===================
+
+U-Boot releases are named by year and patch level, for example 2020.10 means the
+release that came out in October 2020. Release candidates are tagged every few
+weeks as the project heads to the next release. So 2020.10-rc1 was the first
+release candidate (RC), tagged soon after 2020.07 was released.
+
+See https://www.denx.de/wiki/view/U-Boot/ReleaseCycle for full details.
+
+Within the build system, various Makefile variables are created, making use of
+VERSION, PATCHLEVEL and EXTRAVERSION defined at the top of 'Makefile'. There is
+also SUBLEVEL available for downstream use. See also CONFIG_IDENT_STRING.
+
+Some variables end up in a generated header file at
+include/generated/version_autogenerated.h and can be accessed from C source by
+including <version.h>
+
+The following are available:
+
+ UBOOTRELEASE (Makefile)
+ Full release version as a string. If this is not a tagged release, it also
+ includes the number of commits since the last tag as well as the the git
+ hash. If there are uncommitted changes a '-dirty' suffix is added too.
+
+ This is written by scripts/setlocalversion (maintained by Linux) to
+ include/config/uboot.release and ends up in the UBOOTRELEASE Makefile
+ variable.
+
+ Examples::
+
+ 2020.10-rc3
+ 2021.01-rc5-00248-g60dd854f3ba-dirty
+
+ PLAIN_VERSION (string #define)
+ This is UBOOTRELEASE but available in C source.
+
+ Examples::
+
+ 2020.10
+ 2021.01-rc5-00248-g60dd854f3ba-dirty
+
+ UBOOTVERSION (Makefile)
+ This holds just the first three components of UBOOTRELEASE (i.e. not the
+ git hash, etc.)
+
+ Examples::
+
+ 2020.10
+ 2021.01-rc5
+
+ U_BOOT_VERSION (string #define)
+ "U-Boot " followed by UBOOTRELEASE, for example::
+
+ U-Boot 2020.10
+ U-Boot 2021.01-rc5
+
+ This is used as part of the banner string when U-Boot starts.
+
+ U_BOOT_VERSION_STRING (string #define)
+ U_BOOT_VERSION followed by build-time information
+ and CONFIG_IDENT_STRING.
+
+ Examples::
+
+ U-Boot 2020.10 (Jan 06 2021 - 08:50:36 -0700)
+ U-Boot 2021.01-rc5-00248-g60dd854f3ba-dirty (Jan 06 2021 - 08:50:36 -0700) for spring
+
+ U_BOOT_VERSION_NUM (integer #define)
+ Release year, e.g. 2021 for release 2021.01. Note
+ this is an integer, not a string.
+
+ U_BOOT_VERSION_NUM_PATCH (integer #define)
+ Patch number, e.g. 1 for release 2020.01. Note
+ this is an integer, not a string.
+
+Build date/time is also included. See the generated file
+include/generated/timestamp_autogenerated.h for the available
+fields. For example::
+
+ #define U_BOOT_DATE "Jan 06 2021" (US format only)
+ #define U_BOOT_TIME "08:50:36" (24-hour clock)
+ #define U_BOOT_TZ "-0700" (Time zone in hours)
+ #define U_BOOT_DMI_DATE "01/06/2021" (US format only)
+ #define U_BOOT_BUILD_DATE 0x20210106 (hex yyyymmdd format)
+ #define U_BOOT_EPOCH 1609948236
+
+The Epoch is the number of seconds since midnight on 1/1/70. You can convert
+this to a time with::
+
+ $ date -u -d @1609948236
+ Wed 06 Jan 2021 03:50:36 PM UTC
+ $ date -d 'Wed 06 Jan 2021 03:50:36 PM UTC' +%s
+ 1609948236
+
+Every time you build U-Boot this will update based on the time
+on your build machine. See 'Reproducible builds' if you want to
+avoid that.
