Commit c37a6684818d ("stm32mp: fix compilation issue with DEBUG_UART")
split the debug UART initialization code into two files, but failed to
update other non-ST boards. This did not lead to noticeable breakage
until debug UART is enabled, which is not the default. Update the
Makefile accordingly to allow debug UART to work.

Add support for reading out the MAC address from SoC fuses on DH STM32MP1 DHSOM.
The DH STM32MP1 DHSOM may contain external ethernet MACs, which benefit from the
MAC address stored in SoC fuses as well, handle those consistently. This however
means the architecture setup_mac_address() cannot be used and instead a simpler
local fuse read out is implemented in the board file.

The current spl_board_fixups API allows for modification of spl_image
before the SPL jumps to it. This can be used to modify the DT for the
next boot stage, however the current API only allows either the machine
arch or the board to use it.
This limits the utility of the API as there might be certain fixups that
should be applied to all boards sharing the same machine architecture
with others being board specific.
For TI's K3 specifically, this prevents us from performing architecture
level fixups since a lot of TI boards are already making use of the
spl_board_fixups API.
Therefore this patch splits the API into two to allow both board and the
architecture specific fixups. The order is kept as arch then board to
give board specific fixups the precedence.

Describe the u-boot.its generation in stm32mp15xx-dhsom-u-boot.dtsi
binman {} DT node as a replacement for current CONFIG_SPL_FIT_SOURCE
use, dispose of both u-boot-dhcom.its and u-boot-dhcor.its.
Use fdt-SEQ/config-SEQ to generate a list of fdt-N fitImage images {} and
matching configuration {} node entries. The configuration node entry names
no longer encode _somrevN_boardrevN suffix, which was never really used, so
drop this functionality by default. Rework board_fit_config_name_match() to
match on the new configuration node entry names.
Users who do need the match on _somrevN_boardrevN can either replace the
fdt-SEQ/config-SEQ with fixed fdt-N/config-N nodes which each encode the
matching 'description = "NAME_somrevN_boardrevN"' to restore the old
behavior verbatim, or better use SPL DT overlays for U-Boot control DT
the same way e.g. i.MX8MP DHCOM does to support multiple SoM and board
variants.

Enable OF_UPSTREAM to use upstream DT and add st/ prefix to the
DEFAULT_DEVICE_TREE. And thereby directly build DTB from dts/upstream/src/
including *-u-boot.dtsi from arch/$(ARCH)/dts/ directory.
The previous setup used generic SoC prefix like stm32mp15xx-dhco* for
generic DTs which could be used on any STM32MP15xx DHSOM variant. The
new setup uses specific SoC prefix stm32mp157c-dhco* to match Linux DT
names. Since the hardware present on STM32MP153 and STM32MP157 is not
enabled in the board configuration and not supported by U-Boot except
for the DSI host, using the existing Linux DTs poses no issue even on
plain STM32MP151A based SoMs.

Simon Glass <[email protected]> says:
When the SPL build-phase was first created it was designed to solve a
particular problem (the need to init SDRAM so that U-Boot proper could
be loaded). It has since expanded to become an important part of U-Boot,
with three phases now present: TPL, VPL and SPL
Due to this history, the term 'SPL' is used to mean both a particular
phase (the one before U-Boot proper) and all the non-proper phases.
This has become confusing.
For a similar reason CONFIG_SPL_BUILD is set to 'y' for all 'SPL'
phases, not just SPL. So code which can only be compiled for actual SPL,
for example, must use something like this:
#if defined(CONFIG_SPL_BUILD) && !defined(CONFIG_TPL_BUILD)
In Makefiles we have similar issues. SPL_ has been used as a variable
which expands to either SPL_ or nothing, to chose between options like
CONFIG_BLK and CONFIG_SPL_BLK. When TPL appeared, a new SPL_TPL variable
was created which expanded to 'SPL_', 'TPL_' or nothing. Later it was
updated to support 'VPL_' as well.
This series starts a change in terminology and usage to resolve the
above issues:
- The word 'xPL' is used instead of 'SPL' to mean a non-proper build
- A new CONFIG_XPL_BUILD define indicates that the current build is an
'xPL' build
- The existing CONFIG_SPL_BUILD is changed to mean SPL; it is not now
defined for TPL and VPL phases
- The existing SPL_ Makefile variable is renamed to SPL_
- The existing SPL_TPL Makefile variable is renamed to PHASE_
It should be noted that xpl_phase() can generally be used instead of
the above CONFIGs without a code-space or run-time penalty.
This series does not attempt to convert all of U-Boot to use this new
terminology but it makes a start. In particular, renaming spl.h and
common/spl seems like a bridge too far at this point.
The series is fully bisectable. It has also been checked to ensure there
are no code-size changes on any commit.

Test whether this system is compatible with STM32MP15xx DHCOM SoM,
if so, test whether R292 pull up is populated on pin PC3, which is
an indication that the second MAC chip, KS8851-16MLL, is populated.
Use this information to patch 'status' DT property into the second
ethernet MAC DT node and enable/disable the MAC on systems where
the chip is/isn't populated respectively.
Use spl_perform_fixups() to patch the U-Boot proper DT from SPL and
ft_board_setup() to patch Linux DT from U-Boot proper. This way both
software components are configured the same way.

Unlike fdt_node_check_compatible() which returns 0 if node is compatible,
ofnode_device_is_compatible() return true which is non-zero if node is
compatible. The intention of the code is to exit from the function in
case the node is not compatible with "micrel,ks8851-mll". Add the missing
invert into the conditional to reinstate original behavior.
This exposes a follow up problem caused by conversion to DM based FMC2 EBI
driver, where the FMC2 EBI is not configured when accessed by this code.
Probe the KS8851 MAC, which also configures the FMC2 EBI as a dependency,
so that the KS8851 MAC CCR register can be accessed over the FMC2 EBI bus
and checked for EEPROM present bit.
