As the H5 is pin compatible with the H3, vendors tend to upgrade their
existing H3 products with an H5 SoC swap. This is the case with the
Bananapi M2+ H5.
Add the following to support it:

- defconfig: copy of bananapi_m2_plus_h3_defconfig with only SoC
family and default device tree file name changed

Enabling DM_MMC skips the call to mmc_pinmux_setup() in board.c, as this
is supposed to be handled by the MMC driver, using DT information.
However we don't have a pinctrl driver yet, but would still like to keep
the working pinmux setup for our MMC devices. So bring this particular
call back to the DM_MMC code flow.
When booting from either SD card or eMMC, the SPL does the setup for us,
but when booting from SPI or USB we must not skip this part.
Fixes, boot via FEL or SPI flash, where the SPL won't setup the pinmux

Commit a8011eb84dfa("sunxi: board: Print error after power initialization
fails") moved the DRAM init after the increase of the CPU clock
frequency. This lead to various DRAM initialisation failures on some
boards (hangs or wrong size reported, on a NanoPi Duo2 and OrangePi
Zero, for instance). Lowering the CPU frequency significantly (for instance
to 408 MHz) seems to work around the problem, so this points to some timing
issues in the DRAM code.
Debugging this sounds like a larger job, so let's just revert this patch
to bring back those boards.
Beside this probably unintended change the patch just moved the error
message around, so reverting this is not a real loss.
This reverts commit a8011eb84d.

At the moment we rely on the infamous get_ram_size() function to learn
the actual DRAM size in U-Boot proper. This function has two issues:
1) It only works if the DRAM size is a power of two. We start to see
boards which have 3GB of (usable) DRAM, so this does not fit anymore.
2) As U-Boot has no notion of reserved memory so far, it will happily
ride through the DRAM, possibly stepping on secure-only memory. This
could be a region of DRAM reserved for OP-TEE or some other secure
payload, for instance. It will most likely crash in that case.
As the SPL DRAM init routine has very accurate knowledge of the actual
DRAM size, lets propagate this wisdom to U-Boot proper.
We re-purpose a currently reserved word in our SPL header for that.
The SPL itself stores the detected DRAM size there, and bumps the SPL
header version number in that case. U-Boot proper checks for a valid
SPL header and a high enough version number, then uses the DRAM size
from there. If the SPL header field is not sufficient, we fall back to
the old DRAM scanning routine.
Part of the DRAM might be present and probed by SPL, but not accessible
by the CPU. They're restricted in the main U-Boot binary, when accessing
the DRAM size from SPL header.

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.

The current environment has been hardcoded to an offset that starts to be
an issue given the current size of our main U-Boot binary.
By implementing a custom environment location routine, we can always favor
the FAT-based environment, and fallback to the MMC if we don't find
something in the FAT partition. We also implement the same order when
saving the environment, so that hopefully we can slowly migrate the users
over to FAT-based environment and away from the raw MMC one.
Eventually, and hopefully before we reach that limit again, we will have
most of our users using that setup, and we'll be able to retire the raw
environment, and gain more room for the U-Boot binary.

The board has 1GB DDR3 SDRAM, provided by 4 2Gb chips. The mounting holes

- Power input through micro-USB connector (without USB OTG)
- Native 100 Mbps ethernet using the internal PHY, as opposed to

- 4x USB 2.0 host ports, directly connected to the SoC, as opposed to

- TV and audio output on a 3.5mm TRRS jack
- HDMI output
- Micro-SD card slot
- Standard RPi B+ GPIO header, with the standard peripherals routed to
the same pins.
* 5V, 3.3V power, and ground
* I2C0 on the H3 is routed to I2C1 pins on the RPi header
* I2C1 on the H3 is routed to I2C0 pins on the RPi header
* UART1 on the H3 is routed to UART0 pins on the RPi header
* SPI0 on the H3 is routed to SPI0 pins on the RPi header,
with GPIO pin PA17 replacing the missing Chip Select 1
* I2S1 on the H3 is routed to PCM pins on the RPi header
- Additional peripherals from the H3 are available on different pins.
These include I2S0, JTAG, PWM1, SPDIF, SPI1, and UART3
In addition, there are a number of new features:
- Console UART header
- Consumer IR receiver
- Camera interface (not compatible with RPi)
- Onboard microphone
- eMMC expansion module port
- Heatsink mounting holes
This patch adds defconfig and dts files for this board. The dts file is
the same as the one submitted for inclusion in Linux, with some minor
