7ef5b1e7ed ARM: uniphier: enable distro boot
Switch to the distro boot for UniPhier platform.

 - Remove the environment vairalbes used to load images from raw
   block devices.

 - Keep the command to download images via tftp.  This will be
   useful to boot the kernel when no valid kernel image is ready
   yet in the file system.

 - Use root.cpio.gz instead of root.cpio.uboot because we always know
   the file size of the init ramdisk; it is loaded via either a file
   system or network.

 - Rename fit_addr_r to kernel_addr_r, which the distro command
   checks to get the load address of FIT image.

971a54193c doc: fix incorrect usage of DT node unit address
The DT spec demands a unit-address in a node name to match the "reg"
property in that node. Newer dtc versions will throw warnings if this is
not the case.
Fix all occurences in various documentation files where this was not
observed, to not give bad examples to the reader.

81b9bb5fcb ARM: uniphier: merge two defconfig files into uniphier_v7_defconfig
The main difference between Pro4 and PXs2/LD6b is the Denali NAND
IP version.  This is now distinguished by DT.  Merge the two defconfig
files into uniphier_v7_defconfig.

Update the README.uniphier too.

ee8d037ce7 ARM: uniphier: remove SPL support for ARMv8 SoCs
It has been a while since ARM Trusted Firmware supported UniPhier SoC
family.  U-Boot SPL was intended as a temporary loader that runs in
secure world.  It is a maintenance headache to support two different
boot mechanisms.  Secure firmware is realm of ARM Trusted Firmware
and now U-Boot only serves as a non-secure boot loader for UniPhier
ARMv8 SoCs.

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.

3cb9abc9c5 ARM: uniphier: update U-Boot file names in workflow
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.

e69514cc70 ARM: uniphier: fix recommended board setting in document
The mem_is_flash() in arch/arm/mach-uniphier/micro-support_card.c
writes/reads the tail of each NOR flash bank to check if the device
really resides there.

If CS1_SPLIT were enabled, the support card would always require two
NOR flash devices to be inserted for the correct NOR detection.
This is not probably what we want.
