[PATCH v8 0/2] Basic Kontron SMARC-sAL28 board support

Add basic board support for the Kontron SMARC-sAL28 board. Please note,
that this board doesn't support TF-a (yet). Therefore, the u-boot SPL is
the first code which is run and it has to set up the RAM.

changes since v7:
 - removed CONFIG_WDT for now until the watchdog issue is clarified
 - enabled EFIDEBUG and NVEDIT_EFI
 - disabled EFI_LOADER_BOUNCE_BUFFER, doesn't help in my case,
   because efi_load_image() will still do DMA transfers with 64bit
   addresses. ADMA2 (with 64bit address support) support for the
   eSDHC is on the way.

changes since v6:
 - moved README to doc/board/kontron/sl28.rst
 - added device tree files to MAINTAINERS
 - converted preprocessor macros to actual code using IS_ENABLED()
 - fixed sec_init(), use CONFIG_IS_ENABLED() instead of IS_ENABLED()
 - removed unnecessary #ifdef CONFIG_OF_BOARD_SETUP
 - removed CONFIG_SPL_TARGET, because we use binman, this is not needed
   anymore
 - removed unnecessary CONFIG_SYS_MONITOR_BASE macro
 - redefinded memory addresses according to the comment in
   ti_armv7_common.h
 - removed empty BOOTENV for SPL build
 - removed fdt_high and initrd_high
Thanks Tom!

changes since v5:
 - moved CONFIG_ENV_OVERWRITE to defconfig. Thanks Kuldeep!

changes since v4:
 - dropped "armv8: ls1028a: move FSL_LAYERSCAPE to kconfig" as it is
   already upstream
 - new patch "board: sl28: add board specific nvm command"
 - use binman
 - sync device trees with linux
 - use "<devicetree>-u-boot.dtsi" style
 - rebase to lastest master

changes since v3:
 - rebase to latest master
 - use CONFIG_PCI_INIT_R
 - set fdtfile in default environment

changes since v2:
 - add variant 4 support. Since the atheros PHY dt bindings were merged
   into master, we can now use them
 - add environment section in include/configs/kontron_sl28.h
 - add cover letter

changes since v1:
 - fix watchdog device tree reference
