15826e7e70 ARM: uniphier: drop unneeded defines related to legacy serial driver
These defined were used for pre-DM ns16550 serial driver.  They are
unneeded because UniPhier SoCs now use DM serial.

86c3345afb ARM: uniphier: make u-boot-with-spl.bin really available
Commit d085ecd61b ("ARM: uniphier: switch to raw U-Boot image")
claimed that u-boot-with-spl.bin would be useful in its commit log,
but it was not available because the commit missed to define
CONFIG_SPL_MAX_SIZE.  Without it, CONFIG_SPL_PAD_TO is not defined
either (see include/config_fallbacks.h).  So, the SPL image is not
padded correctly.

d085ecd61b ARM: uniphier: switch to raw U-Boot image
Now everything is done to load a raw U-Boot proper image instead of
an mkimage-processed one (as far as I tested on NAND, eMMC, NOR).

The SPL already knows the load address of the U-Boot proper without
parsing its uImage header because the load address is defined by
CONFIG_SYS_TEXT_BASE, assuming that the two images are generated from
the same build.

My main motivation of this switch is to use u-boot-with-spl.bin, a
concatenation of u-boot-spl.bin and u-boot.bin.  (I wish there were
a concatenation of u-boot-spl.bin and u-boot.img...)  Anyway, this
commit would be useful for one-shot image burn.

c231c4367a ARM: uniphier: add emmcupdate command
The Boot ROM expects the boot image (SPL) in the Boot Partition 1.
So, updating images involves the hardware partition switch.  It might
be a bit advanced for some users.

To be user-friendly, this commit adds a useful command to update the
images; just put SPL and U-Boot proper into the public directory of
the TFTP server and execute "run emmcupdate" from the command line.

755c7d9a61 ARM: uniphier: change stack pointer address for SPL
No special reason for the current stack address 0x0ff08000.
Change it to 0x00100000 to simplify the init_page_table.

There are two types of SoCs in terms of the load address of SPL.

 [1] PH1-sLD3, PH1-LD4, PH1-sLD8
   SPL is loaded at 0x00040000-0x0004ffff
 [2] PH1-Pro4, PH1-Pro5, ProXstream2, PH1-LD6b
   SPL is loaded at 0x00100000-0x0010ffff

The new stack area (0x000f8000-0x00100000) should be safe for all the
cases.

Since commit ad1ecd2063 ("fdt: Build a U-Boot binary without device
tree") and commit 03c25bcd26 ("fdt: Build an SPL binary without
device tree"), we can use shorter file names for the output images.

The default configuration for UniPhier SoCs enables CONFIG_OF_SEPARATE
and CONFIG_SPL_OF_CONTROL.  In this case, spl/u-boot-spl.bin is the
same as spl/u-boot-spl-dtb.bin.  Likewise, u-boot.img is the same as
as u-boot-dtb.img.  So, this change of the flow has no impact.

89835b3557 ARM: uniphier: allow to run zImage rather than uImage
UniPhier SoC family adopt ARM Multi-platform in Linux since the first
upstreaming.  Because CONFIG_ARM_PATCH_PHYS_VIRT is defined, the
kernel image is completely position-independent.  There is no reason
to decide the load address on compile time, but it is up to the boot
loader.  Now, zImage is handier than uImage, also it allows to skip
the relocation of the kernel image.

323d1f9d5b ARM: uniphier: allow to enable multiple SoCs
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.

Now init functions called from board_postclk_init() and dram_init()
are only necessary for SPL.
Move them to spl_board_init() for clean-up.

84ccd791af ARM: UniPhier: move pin_init() to board_early_init_f()
Currently, I/O pin settings are not necessary for SPL.
The board_early_init_f() seems a suitable place to call pin_init().

75bc8e85b5 ARM: UniPhier: add environment variable to update images in NAND
To boot UniPhier boards with the NAND boot mode, two images
(u-boot-spl.bin and u-boot-dtb.img) must be written at the correct
offset addresses.

TFTP downloading is useful to update such images in the NAND device.
We generally do:

  => nand erase 0 0x100000
  => tftpboot u-boot-spl.bin
  => nand write $loadaddr 0 0x10000
  => tftpboot u-boot-dtb.img
  => nand write $loadaddr 0x10000 0xf0000

It is a tedious and error-prone operation.

This commit provides the shorthand:

  => run nandupdate

The normal image is working on DRAM.  It is better to use DRAM also
for init stack than L2 cache.

7a3620b246 ARM: UniPhier: detect the number of flash banks at run-time
Some UniPhier boards are equipped with an expansion slot that
some optional SRAM/NOR-flash cards can be attached to.  So, run-time
detection of the number of flash banks would be more user-friendly.

Until this commit, UniPhier boards have achieved this by (ab)using
board_flash_wp_on() because the boot failed if flash_size got zero.
Fortunately, this problem was solved by commit 70879a9256 (flash:
do not fail even if flash_size is zero).

Now it is possible to throw away such a tricky workaround.  This
commit also enables CONFIG_SYS_MAX_FLASH_BANKS_DETECT for further
refactoring.

among the config headers of UniPhier SoC variants is getting smaller
