This configuration is supposed to be used with ARM Trusted Firmware,
so the SYSTEM_RESET is implemented in BL31.  Invoke PSCI instead of
U-Boot's own reset code because we need to coordinate with SCP
(System Control Processor) for the system-level power management.

We repeated partial moves for CONFIG_SYS_NO_FLASH, but this is
not completed. Finish this work by the tool.

During this move, let's rename it to CONFIG_MTD_NOR_FLASH.
Actually, we have more instances of "#ifndef CONFIG_SYS_NO_FLASH"
than those of "#ifdef CONFIG_SYS_NO_FLASH".  Flipping the logic will
make the code more readable.  Besides, negative meaning symbols do
not fit in obj-$(CONFIG_...) style Makefiles.

This commit was created as follows:

[1] Edit "default n" to "default y" in the config entry in
    common/Kconfig.

[2] Run "tools/moveconfig.py -y -r HEAD SYS_NO_FLASH"

[3] Rename the instances in defconfigs by the following:
  find . -path './configs/*_defconfig' | xargs sed -i \
  -e '/CONFIG_SYS_NO_FLASH=y/d' \
  -e 's/# CONFIG_SYS_NO_FLASH is not set/CONFIG_MTD_NOR_FLASH=y/'

[4] Change the conditionals by the following:
  find . -name '*.[ch]' | xargs sed -i \
  -e 's/ifndef CONFIG_SYS_NO_FLASH/ifdef CONFIG_MTD_NOR_FLASH/' \
  -e 's/ifdef CONFIG_SYS_NO_FLASH/ifndef CONFIG_MTD_NOR_FLASH/' \
  -e 's/!defined(CONFIG_SYS_NO_FLASH)/defined(CONFIG_MTD_NOR_FLASH)/' \
  -e 's/defined(CONFIG_SYS_NO_FLASH)/!defined(CONFIG_MTD_NOR_FLASH)/'

[5] Modify the following manually
  - Rename the rest of instances
  - Remove the description from README
  - Create the new Kconfig entry in drivers/mtd/Kconfig
  - Remove the old Kconfig entry from common/Kconfig
  - Remove the garbage comments from include/configs/*.h

This defconfig does not support SPL.  If you use this, the basic
SoC initialization must be done in firmware that runs before U-Boot.
(Generally, ARM Trusted Firmware is expected to do this job).

Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

We may want to run different firmware before running U-Boot.  For
example, ARM Trusted Firmware runs before U-Boot, making U-Boot
a non-secure world boot loader.  In this case, the SoC might be
initialized there, which enables us to skip SPL entirely.

This commit removes "select SPL" to make it configurable.  This
also enables the Multi SoC support for the UniPhier ARMv8 SoCs.
(CONFIG_ARCH_UNIPHIER_V8_MULTI)  Thanks to the driver model and
Device Tree, the U-Boot proper part is now written in a generic way.
The board/SoC parameters reside in DT.  The Multi SoC support
increases the memory footprint a bit, but the U-Boot proper does
not have strict memory constraint.  This will mitigate the per-SoC
(sometimes per-board) defconfig burden.

Currently, CONFIG_MMC is not related to any other options by
"depends on" or "select".  One of big advantages of using Kconfig

it.  As the first step, make the existing MMC driver entries depend
on MMC.

Commit 7a777f6d ("mmc: Add generic Kconfig option") created
a Kconfig entry for this option without any actual moves, then
commit 44c79879 ("sunxi: Use Kconfig CONFIG_MMC") moved
instances only for SUNXI.

We generally do not like such partial moves.  This kind of work
is automated by tools/moveconfig.py, so it is pretty easy to
complete this move.

I am adding "default ARM || PPC || SANDBOX" (suggested by Tom).
This shortens the configs and will ease new board porting.

This reverts commit 90c08d9e.

I took a closer look at this after the commit was applied, and found
CONFIG_SYS_MALLOC_F_LEN=0x2000 was too much.  8KB memory for SPL is
actually too big for some boards.  Perhaps 0x800 is enough, but the
situation varies board by board.

Let's postpone our decision until we come up with a better idea.

Some boards' defconfigs are disordered. Reorder them.

Signed-off-by: Bin Meng <bmeng.cn@gmail.com>

Before this commit, the Kconfig menu in mach-uniphier only allowed us
to choose one SoC to be compiled.  Each SoC has its own defconfig file
for the build-test coverage.  Consequently, some defconfig files are
duplicated with only the difference in CONFIG_DEFAULT_DEVICE_TREE and
CONFIG_{SOC_NAME}=y.

Now, most of board-specific parameters have been moved to device trees,
so it makes sense to include init code of multiple SoCs into a single
image as long as the SoCs have similar architecture.  In fact, some
SoCs of UniPhier family are very similar:
 - PH1-LD4 and PH1-sLD8
 - PH1-LD6b and ProXstream2 (will be added in the upcoming commit)

This commit will be helpful to merge some defconfig files for better

In the next commit, I will add "u-boot,dm-pre-reloc" to the "soc"
(simple-bus) nodes in UniPhier device trees.  But, before that,
CONFIG_SYS_MALLOC_F_LEN must be increased.

Adding "u-boot,dm-pre-reloc" to a simple-bus node causes it to bind
all of its child nodes.  (See simple_bus_post_bind() function)

Actually, I want only UART0 and pinctrl to be bound in SPL and before
relocation in U-boot proper.  But, with "u-boot,dm-pre-reloc" in the
simple-bus node, all the other unwanted nodes are also bound.  The
default value for CONFIG_SYS_MALLOC_F_LEN, 0x400, is not enough for
that.  Increase the pre-reloc malloc size to 0x2000, hoping the root
cause will be fixed later.
