[U-Boot] [PATCH v5 0/7] toradex: config block handling

[Marcel Ziswiler]

This series integrates Toradex factory configuration block handling. The
config block is a data structure which gets stored to flash during
production testing. The structure holds such information as board resp.
hardware revision, product ID and serial number which is used as the NIC
part of the Ethernet MAC address as well. The config block will be read
upon boot by the show_board_info() function, displayed as part of the
board information and passed to Linux via device tree or ATAGs.

Changes in v5:
- get rid of choice for config block location as it causes issues due to
  Kconfig multi sourcing (which BTW is not my invention as I simply
  copied TI's way of doing that for their common stuff) and anyway does
  not make much sense

Changes in v4:
- add various peoples acked- resp. reviewed-bys with which it now
  hopefully could be pulled in ASAP

Changes in v3:
- introduce new patch dropping unused CONFIG_CUSTOM_BOARDINFO by
  reverting commit a9ad18c9d5fe2554753b0f9a52adfd5ebce61147
- introduce new patch making show_board_info() a weak function which
  allows for custom board specific implementations thereof
- fixup deactivation of CONFIG_DISPLAY_BOARDINFO in favour of
  CONFIG_DISPLAY_BOARDINFO_LATE which also displays on the LCD after
  recent move thereof to Kconfig
- use custom show_board_info() rather than checkboard() and
  checkboard() rather than checkboard_fallback()
- also reword commit message accordingly
- use checkboard() rather than checkboard_fallback()
- drop CUSTOM_BOARDINFO
- drop patch 1 'colibri_imx7/vf: move to custom checkboard_fallback()'
  in favour of Stefan's proposed solution

Changes in v2:
- fixed common.h include mess in board/toradex/common by renaming
  common* to tdx-common
- renamed TRDX to TDX and trdx to tdx as in common use internally
- consolidated makefiles and changed copyright message
- renamed configblock* to tdx-cfg-block* analogous to Kconfig symbols
- moved board/toradex/common/Kconfig sourcing from arch/arm/Kconfig
  into our own board Kconfig files
- use a named choice for the config block location for above to work
  without issuing any warnings (undocumented kbuild feature curtsey
  Arnaud Lacombe)
- added CUSTOM_BOARDINFO into our common Kconfig to avoid recent
  no_new_adhoc_configs_check error
- add Max' patch
