This file contains lots of internal details about the environment. Most
code can include env.h instead, calling the functions there as needed.
Rename this file and add a comment at the top to indicate its internal
nature.

The PHY LED mode register mask should be 0xc000 , not 0xc0000.
Correct the mask to operate on the right bits.

This patch renames the routine fdtdec_setup_memory_size()
to fdtdec_setup_mem_size_base() as it now fills the
mem base as well along with size.

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.

Pull the symbol from the boards and zap struct rmobile_sysinfo as they
are rather useless. The entire purpose of that whole machinery was to
print board name in the CONFIG_ARCH_RMOBILE_BOARD_STRING. Do that in a
far simpler and more contained manner.

When U-Boot is started via JTAG, ignore the installed environment
as it may interfere with the recovery of the board.

Pull the SPL code from porter.c into a separate file in
preparation for the addition of system initialization code.
No functional change.

The 'reset' command did not work on Porter because the reset code
was accessing the wrong PMIC address over broken I2C bus driver.
Replace the code with DM-aware code and fix up the PMIC address.
This makes the 'reset' command work again.

NOTE: This should be moved to the SH ethernet driver, but it's quite
late in the cycle, so this is something to be done in 2018.05.

Due to size limitations of the MERAM, switch U-Boot to SPL.
The SPL is loaded by the SPI_LOADER into MERAM and then loads
U-Boot proper into DRAM. This way U-Boot can freely grow in
size in DRAM, as there is plenty of it.

NOTE: To update U-Boot, first install u-boot.img to 0x140000 in SPI NOR,
then use the Minimon to flash u-boot-spl.srec using ls,2,e6304000.
To generate u-boot-spl.srec, use objcopy:
arm-linux-gnueabi-objcopy -O srec spl/u-boot-spl u-boot-spl.srec

Convert the R8A7791 Porter board to DM and DT. This implies mostly
enabling the necessary configuration options and plucking out the
ad-hoc configuration from the board file. Moreover, the pre-reloc
malloc size was increased to allow the clock driver to start up
early without running out of malloc space and the early stack was
moved further up in the DRAM to avoid rewriting U-Boot itself.
