The config option has been removed by one of the syncs with the Linux
mainline MTD subsystem:
ff94bc40af (mtd, ubi, ubifs: resync with Linux-3.14)
It has been left inside the config files. Currently does not look to
serve any purpose, so remove it now from all the configs.Signed-off-by: Igor Grinberg

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
maintainability.Signed-off-by: Masahiro Yamada

Currently, console=ttyS0 is hard-coded in CONFIG_EXTRA_ENV_SETTINGS
and it replaces the bootargs in the chosen node of the device tree
passed to the kernel. This is not preferable because I am going to
add some boards whose console is not ttyS0.Drop bootargs settings from U-Boot's environment and use the one in
device tree by default.Signed-off-by: Masahiro Yamada

Move init code of low-level debug into a single file.
This is helpful to create an image that runs on multiple SoCs.Signed-off-by: Masahiro Yamada

Currently, IECTRL is enabled after pin-mux settings for the low-level
debugging for PH1-LD4 and PH1-sLD8. While IECTRL is disabled, input
signals are pulled-down, i.e. glitch signal (Low to High transition)
problem occurs if pin-mux is set up first. As a result, one invalid
character is input to the UART block and the auto-boot counting is
terminated immediately.The correct initialization procedure is:
[1] Enable IECTRL (if IECTRL exists for the pins)
[2] Set up pin-muxing
[3] Deassert the reset of the hardware blockCurrently, the low-level debugging is working for PH1-sLD3 and
PH1-Pro4, but just in case, follow the sequence for all the SoCs.Signed-off-by: Masahiro Yamada

The UART I/O ports for PH1-Pro4 has no input enable controlling.

Without this, build fails if CONFIG_MICRO_SUPPORT_CARD is disabled.

It is no longer necessary to define CONFIG_SUPPORT_CARD_* globally.
Move them to a C file as local macros. Also, rename the C file.Signed-off-by: Masahiro Yamada
-
The macro, led_write(), is now only used in C sources. There is no
more reason to keep the tricky assembly macro. Replace it with a
new C function led_puts().Also, rename board.h to micro-support-card.h.

The wrapper functions, uniphier_board_*, are just making function
calls complex. Remove them.Also, use empty inline functions in case CONFIG_MICRO_SUPPORT_CARD
is disabled, so that prototype checking works.Signed-off-by: Masahiro Yamada

To achieve the complete run-time configuration by device trees, ifdef

In UniPhier SoCs before ProXstream2 and PH1-LD6b, two address spaces
0x00000000 - 0x0fffffff
0x40000000 - 0x4fffffff
are both mapped to the external bus (also called system bus),
so either was OK.In the newest two SoCs, the former (0x00000000 - 0x0fffffff) is
assigned for the serial NOR interface.Going forward, use the latter for the external bus.

Historically (for compatibility with very old platforms), two
different types of micro support cards have been used with the
UniPhier SoC development boards. It has been painful to maintain
both. Having one of them is enough.Signed-off-by: Masahiro Yamada

These input enable settings are handled by the pinctrl drivers.
Because the external bus pins are input-enabled by default, on-board
devices such as LED still work fine even with this delayed input
enabling.Signed-off-by: Masahiro Yamada

As the UniPhier serial driver had already switched to Drive Model
and the pinctrl drivers are now enabled, these pin-muxing settings
are properly handled by the pinctrl drivers.Signed-off-by: Masahiro Yamada

Now, UniPhier SoCs are ready to enable pinctrl drivers.

Add "u-boot,dm-pre-reloc" for device nodes we want in SPL DTB
(spl/u-boot-spl.dtb).The "soc" node (this is simple-bus node) also needs the property
to bind the pinctrl node located under it.I am collecting this U-Boot specific hack to the bottom of board
DTS rather than inserting "u-boot,dm-pre-reloc" into SoC DTSI.
My goal is to sync DTSI with Linux for easier maintenance.Signed-off-by: Masahiro Yamada

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.Signed-off-by: Masahiro Yamada

In UniPhier device trees, pinctrl device nodes are located under the
simple-bus (AMBA).This is needed to bind pinctrl devices in SPL.
