5f588f831b arm: Finish migration of CONFIG_MACH_TYPE
As this is only useful when booting with ATAGs, which are now largely
disabled, remove this value for the remaining platforms.  We have a few
places in the code that had been testing for MACH_TYPE as a sort of
internal logic.  Update those to use different but still correct CONFIG
symbols.

9774462e34 arm: Disable ATAGs support
With the exceptions of ds109, ds414, icnova-a20-swac, nokia_rx51 and
stemmy, disable ATAG support.  A large number of platforms had enabled
support but never supported a kernel so old as to require it.  Further,
some platforms are old enough to support both, but are well supported by
devicetree booting, and have been for a number of years.  This is
because some of the ATAGs related functions have been re-used to provide
the same kind of information, but for devicetree or just generally to
inform the user.  When needed still, rename these functions to
get_board_revision() instead, to avoid conflicts.  In other cases, these
functions were simply unused, so drop them.

b9d66a061b imx: Convert SERIAL_TAG support to ENV_VARS_UBOOT_RUNTIME_CONFIG
No iMX platforms have supported ATAG-based booting.  They have however
re-used the CONFIG_SERIAL_TAG option as a way to enable support of
reading the OTP fuses and setting the serial# environment variable in
some cases.  Change the warp7 support to use this symbol, use this for
updating the rest of the imx7 code, and update the imx8 conditionals.

9d8665b709 i2c: Convert CONFIG_POWER_I2C et al to Kconfig
This converts the following to Kconfig:
   CONFIG_POWER_I2C
   CONFIG_POWER_LEGACY

They are handled at the same time due to a dependency between them.
Update the Makefile rule to use legacy power only in U-Boot proper.
Unfortunately a separate rule is needed in SPL to be able to build
legacy power.  Add SPL related symbols for both, to allow for SPL-only
usage.

29d7153ec3 power: Rename CONFIG_POWER to CONFIG_POWER_LEGACY
This option is used in pre-driver model code and much of it has never
been converted to driver model.

We want to add a new option to enable power support, so we can use a
simple rule in the Makefile. Rename this one, which is really about
a particular implementation of power.

Also update the pmic.h header file so it either includes the legacy
API or the driver model one.

0017931971 Revert most of the series for adding vexpress_aemv8r support
Per a request from Andre Przywara and agreed with by Peter Hoyes, the

b53bbca63b vexpress64: Add BASER_FVP vexpress board variant
The BASER_FVP board variant is implemented on top of the BASE_FVP board
config (which, in turn, is based on the Juno Versatile Express board
config). They all share a similar memory map - for BASER_FVP the map is
inverted from the BASE_FVP
(https://developer.arm.com/documentation/100964/1114/Base-Platform/Base---memory/BaseR-Platform-memory-map)

 * Create new TARGET_VEXPRESS64_BASER_FVP target, which uses the same
   board config as BASE_FVP and JUNO
 * Adapt vexpress_aemv8a.h header file to support BASER_FVP (and rename
   to vexpress_aemv8.h)
 * Enable config to switch to EL1 for the BASER_FVP
 * Create vexpress_aemv8r defconfig
 * Provide an MPU memory map for the BASER_FVP

For now, only single core boot is supported.

f629895fa3 board: stemmy: Update documentation
Over the time, the "stemmy" U-Boot board was tested on several other
Samsung smartphones based on ST-Ericsson NovaThor Ux500. Convert the
documentation to reStructuredText at doc/board/ste/stemmy.rst and
make the device list complete. Also note that the board now boots
into USB Fastboot instead of just ending up at the U-Boot prompt.

The device table is mostly taken from the postmarketOS wiki article
(https://wiki.postmarketos.org/wiki/ST-Ericsson_NovaThor_U8500).
All the newly added devices were tested by Linus Walleij.

1c5aedcd9a board: x530: switch to wdt_stop_all()
Since the gd->watchdog_dev member is going away, switch to using the
new wdt_stop_all() helper.

While here, clean up the preprocessor conditional: The ->watchdog_dev
member is actually guarded by CONFIG_WDT [disabling that in
x530_defconfig while keeping CONFIG_WATCHDOG breaks the build], and in
the new world order so is the existence of the wdt_stop_all()
function.

Actually, existence of wdt_stop_all() depends on CONFIG_${SPL_}WDT, so
really spell the condition using CONFIG_IS_ENABLED, and make it a C
rather than cpp if.

52ff1626cf xilinx: common: Enabling generic function for DT reselection
U-Boot support board detection at run time and based on it change DT.
This feature is implemented for SOM Kria platforms which contain two
eeproms which contain information about SOM module and CC (Carrier card).
Full U-Boot starts with minimal DT file defined by
CONFIG_DEFAULT_DEVICE_TREE which is available in multi DTB fit image.
It is using default setup of board_name variable initializaed to
DEVICE_TREE which corresponds to CONFIG_DEFAULT_DEVICE_TREE option.

When DTB_RESELECT is enabled board_detection() is called. Keep it your mind
that this code is called before relocation. board_detection() is calling
xilinx_read_eeprom() which fills board_info (xilinx_board_description)
structure which are parsed in board_name_decode().
Based on DT configuration and amount of nvmemX aliases name of the board is
composed by concatenating CONFIG_SYS_BOARD "-" <board_name> "-rev"
<board_revision> "-" <cc_name> "-rev" <cc_revision>.

If CC is not present or more are available it keeps going.

When board name is composed and returned from board_name_decode() it is
assigned to board_name variable which is used by
board_fit_config_name_match() which is called via fdtdec_setup() when it
goes over config options in multi dtb FIT image.

From practical point of view multi DTB image is key point here which has to
contain configs for detected combinations. Unfortunately as of now they
have to be full DTBs and DTBOs are not supported.

That's why configuration like:
config_X {
	description = "zynqmp-board-cc";
	fdt = "board", "cc";
};

needs to be squashed together with:
fdtoverlay -o zynqmp-board-cc -i arch/arm/dts/zynqmp-board.dtb \
arch/arm/dts/zynqmp-cc.dtbo

and only one dtb is in fit:
config_X {
	description = "zynqmp-board-cc";
	fdt = "board-cc";
};

For creating multi DTBs fit image use mkimage -E, e.g.:
mkimage -E -f all.its all.dtb

When DTB_RESELECT is enabled xilinx_read_eeprom() is called before
relocation and it uses calloc for getting a buffer. Because this is dynamic
memory it is not relocated that's why xilinx_read_eeprom() is called again
as the part of board_init(). This second read with calloc buffer placed in
proper position board_late_init_xilinx() can setup u-boot variables as
before.

5bd5ee02b2 xilinx: zynqmp: Check that DT is 64bit aligned
DT needs to be 64bit aligned. If it is not fdt64_to_cpu will fail when try
to read information about reserved memory. The system ends in exception
without any clue what's going it. That's why detect not aligned DT and
panic to show where the issue is coming from.

8823253272 xilinx: Add support for generic board detection
Add support for changing DT at run time. It is done via board_detection()
which returns platform_id and platform_version which can be used via
board_name_decode() to compose board_local_name string which corresponds
with DT which is should be used.

d9c93c9e2c xilinx: common: Change board_info[] handling
Origin code was allocating only pointers to struct xilinx_board_description
and there was separate allocation for structure self and freeing in case of
failure.
The code is directly allocating space for all structures by one calloc to
simlify logic.

57f710320f xilinx: Use variable for passing board_name
Use variable which points to DEVICE_TREE by default. The reason for this
change is to enable DTB_RESELECT and MULTI_DTB_FIT where board detection
can be used for change DTB at run time. That's why there must be reference
in board_fit_config_name_match() via variable instead of hardcoding it
which is sufficient for that use case.

530560b6f8 xilinx: fru: Replace spaces with \0 in detected name
FRU spec expected \0 for unused symbols but unfortunately a lot of boards
are using spaces instead of \0. That's why after saving it to desc->name
name is checked again and all spaces are converted to \0. This will ensure
that names can be used for string manipulations like concatenation.
