As discussed at [1], the Amlogic Meson GX SoCs can embed a BL31 firmware
and a secondary BL32 firmware.
Since mid-2017, the reserved memory address of the BL31 firmware was moved
and grown for security reasons.
But mainline U-Boot and Linux has the old address and size fixed.
These SoCs have a register interface to get the two firmware reserved
memory start and sizes.
This patch adds a dynamic reservation of the memory zones in the device tree bootmem
reserved memory zone used by the kernel in early boot.
To be complete, the memory zones are also added to the EFI reserved zones.
Depends on patchset "Add support for Amlogic GXL Based SBCs" at [2].

Changes since v1:
- switched the #if to if(IS_ENABLED()) to compile all code paths
- renamed function to meson_board_add_reserved_memory()
- added a mem.h header with comment
- updated all boards ft_board_setup()
Changes since RFC v2:
- reduced preprocessor load
- kept Odroid-C2 static memory mapping as exception
Changes since RFC v1:
- switch to fdt rsv mem table and efi reserve memory
- replaced in_le32 by readl()

Having this as a 'default y' is rather annoying because it doesn't
actually compile unless other options are defined in the board header:
../cmd/bootm.c: In function 'do_imls_nor':
../cmd/bootm.c:330:7: error: 'CONFIG_SYS_MAX_FLASH_BANKS' undeclared (first use in this function); did you mean 'CONFIG_SYS_MAX_FLASH_SECT'?
i < CONFIG_SYS_MAX_FLASH_BANKS; ++i, ++info) {
Make it 'default n' so people who develop new boards that start from a
blank defconfig have one less compilation failure to debug.

This converts the following to Kconfig:
CONFIG_ENV_IS_IN_MMC
CONFIG_ENV_IS_IN_NAND
CONFIG_ENV_IS_IN_UBI
CONFIG_ENV_IS_NOWHERE
In fact this already exists for sunxi as a 'choice' config. However not
all the choices are available in Kconfig yet so we cannot use that. It
would lead to more than one option being set.
In addition, one purpose of this series is to allow the environment to be
stored in more than one place. So the existing choice is converted to a
normal config allowing each option to be set independently.
There are not many opportunities for Kconfig updates to reduce the size of
this patch. This was tested with
./tools/moveconfig.py -i CONFIG_ENV_IS_IN_MMC
And then manual updates. This is because for CHAIN_OF_TRUST boards they
can only have ENV_IS_NOWHERE set, so we enforce that via Kconfig logic
now.

The Odroid C2 comes with several expansion options such as an RTC module.
As these expansions are not considered in the Linux device tree they have

We convert CONFIG_PARTITION_UUIDS to Kconfig first. But in order to cleanly
update all of the config files we must also update CMD_PART and CMD_GPT to also
be in Kconfig in order to avoid complex logic elsewhere to update all of the
config files.

Use the generic "distro" boot framework to enable automatic DHCP boot.
MMC and USB are not yet implemented, so this is the only boot option.
The fdt and kernel addresses are adopted from downstream; ramdisk and
scriptaddr addresses were chosen arbitrarily.

Commit 7a777f6d6f ("mmc: Add generic Kconfig option") created
a Kconfig entry for this option without any actual moves, then
commit 44c798799f ("sunxi: Use Kconfig CONFIG_MMC") moved
instances only for SUNXI.
We generally do not like such partial moves. This kind of work
is automated by tools/moveconfig.py, so it is pretty easy to
complete this move.
I am adding "default ARM || PPC || SANDBOX" (suggested by Tom).
This shortens the configs and will ease new board porting.
This commit was created as follows:
[1] Edit Kconfig (remove the "depends on", add the "default",
copy the prompt and help message from Linux)
[2] Run 'tools/moveconfig.py -y -s -r HEAD MMC'
