6717e15447 ARM: uniphier: delete or replace <common.h> includes
<common.h> pulls in a lot of bloat. <common.h> is unneeded in most of
places.

0914011310 command: Remove the cmd_tbl_t typedef
We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.

Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.

This requires quite a few header-file additions.

d41b358fb3 ARM: uniphier: de-couple SG macros into base address and offset
The SG_* macros represent the address of SoC-glue registers.
For a planned new SoC, its base address will be changed.

Turn the SG_* macros into the offset from the base address.

b521ea3958 ARM: uniphier: include <linux/io.h> from boot-device.c
This file calls readl(), so needs to include <linux/io.h>.
Currently, it relies on someone else including it.

40c1a466ce ARM: uniphier: remove unused uniphier_ld11_boot_device_fixup()
The .boot_device_fixup() is only called by SPL.

Now that 64-bit SoCs of this SoC family no longer support SPL,
debug-uart-ld20.c is never compiled.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

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.

For these SoCs, show the information if STM is enabled.

9d35873161 ARM: uniphier: add simple eMMC load APIs instead of ROM API
Re-use of routines embedded in the Boot ROM requires a function
pointer table for each SoC.  This is not nice in terms of the
maintainability in a long run.

Implement simple eMMC load APIs that are commonly used for LD11,
LD20, and hopefully future SoCs.
