74b869bae7 efi_loader: use CONFIG_STACK_SIZE in the UEFI sub-system
The Kconfig symbol CONFIG_STACK_SIZE is used both by ARM and Microblaze
with the same meaning. Move it to menu 'General setup' so that we can use
it for all architectures.

Use the value of CONFIG_STACK_SIZE instead of a hard coded 16 MiB value for
reserving memory in the UEFI sub-system.

d91cf006ee Kconfig: Remove redundant variable sets
In a few places we have Kconfig entries that set SPL_LDSCRIPT to what is
the default value anyways.  Drop these.

e0418347f9 microblaze: Setup initrd_high and fdt_high at run time
Setup initrd_high and fdt_high to be placed in lowmem space for kernel to
be able to reach it. Values are setup at run time to ensure that the same
setting can be used on different memory setup. Do this setting only when
variables are not

Similar run time detection was done for Zynqmp and Versal.

08a00cba06 dm: Change CMD_DM enabling
CMD_DM is used for debug purpose and it shouldn't be enabled by default
via Kconfig. Unfortunately this is in the tree for quite a long time
that's why solution is to use imply DM for all targets which are
enabling DM.

4a69366967 microblaze: Convert generic platform to DM gpio
Converting GPIO to DM requires to do changes in reset subsystem
that's why support for Microblaze soft reset via sysreset and GPIO
sysreset support was added.
These two patches enables enabling GPIO DM.
Microblaze soft reset is bind at last reset method.

GPIO reset is handled via sysreset with adding this fragment to DT.

gpio-restart {
	compatible = "gpio-restart";
	gpios = <&reset_gpio 0 0 0>;
	/* 3rd cell ACTIVE_HIGH = 0, ACTIVE_LOW = 1 */
};

hard-reset-gpio property is not documented and also handled.
Conversion is required.

Unfortunately do_reset is required for SPL that's why use only soft
microblaze reset for now.

b529993e02 spl: add hierarchical defaults for SPL_LDSCRIPT
With SPL_LDSCRIPT moved to Kconfig (and this being a 'string' config
node), all the lingering definitions in header files will cause
warnings/errors due to the redefinition of the configuration item.

As we don't want to pollute the defconfig files (and values should
usually be identical for entire architectures), the defaults are moved
into Kconfig.  Kconfig will always pick the first default that
matches, so please keep these values at the end of each file (to allow
any board-specific Kconfig, which will be included earlier) to
override with an unconditional default setting.

461be2f96e kconfig: remove redundant "string" type in arch and board Kconfigs
Now the types of CONFIG_SYS_{ARCH, CPU, SOC, VENDOR, BOARD, CONFIG_NAME}
are specified in arch/Kconfig.

We can delete the ones in arch and board Kconfig files.

This commit can be easily reproduced by the following command:

find . -name Kconfig -a ! -path ./arch/Kconfig | xargs sed -i -e '
/config[[:space:]]SYS_\(ARCH\|CPU\|SOC\|\VENDOR\|BOARD\|CONFIG_NAME\)/ {
    N
    s/\n[[:space:]]*string//

dd84058d24 kconfig: add board Kconfig and defconfig files
This commit adds:
 - arch/${ARCH}/Kconfig
    provide a menu to select target boards
 - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
    set CONFIG macros to the appropriate values for each board
 - configs/${TARGET_BOARD}_defconfig
    default setting of each board

(This commit was automatically generated by a conversion script
based on boards.cfg)

In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.

But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.
