Add two functions which can find a child device by uclass or by name.
The first is useful with Multi-Function-Devices (MFDs) to find one of a
particular type. The second is useful when only the name is known.

This allow for convenient use of QEMU machine to test loading of UBI
filesystem. There are a couple of changes made together of this which
are required:
1) The malloc must be at least 512 KiB to allow the use of UBI
filesystem. We are going to enable it in a next patch.
2) MTD_DEVICE must be enabled, otherwise we get missing symbols
during the build
Following configs were change:

When the spi_flash_probe_bus_cs() was previously called, it was
called using 0's for two values where CONFIG_ENV_SPI_MAX_HZ and
CONFIG_ENV_SPI_MODE are now used. When changed this
caused the environment to fail the CRC check and the default

Recent removal of obsolete partition led to shifting of starting address
of "reserved" partition (which reflects U-Boot environment). Fix its
start address to keep it in sync with ENV_OFFSET and DFU environment.
This patch also provides fixed start address for "reserved" partition,
so that we can track when it's shifted next time.
While at it, move it before "misc" partition to keep all Android
partitions together.

Based on the MCU R5 efuse settings, R5F cores in MCU domain
either work in split mode or in lock step mode.
If efuse settings are in lockstep mode: ROM release R5 cores
and SPL continues to run on the R5 core is lockstep mode.
If efuse settings are in split mode: ROM releases both the R5
cores simultaneously and allow SPL to run on both the cores.
In this case it is bootloader's responsibility to detect core
1 and park it. Else both the core will be running bootloader
independently which might result in an unexpected behaviour.

The Amlogic Meson SoCs ROM supports a boot over USB with a custom protocol.
When no other boot medium are available (or by forcing the USB mode), the
ROM sets the primary USB port as device mode and waits for a Host to
enumerate.
When enumerated, a custom protocol described at [1] permits writing to
memory and execute some specific FIP init code to run the loaded
Arm Trusted Firmware BL2 and BL3 stages before running the BL33 stage.
In this mode, we can load different binaries that can be used by U-boot
like a script image file.
This adds support for a custom USB boot stage only available when the
boot mode is USB and the script file at a pre-defined address is valid.
This support was heavily copied from the Sunxi Allwinner FEL U-Boot support.
The tool pyamlboot described at [2], permits using this boot mode on boards
exposing the first USB port, either as OTG or Host port.

the Amlogic GXL SoCs with :
- Same 4xCortex-A53 CPUs but clocked at 1.2GHZ max
- DDR Interface limited to DDR4 16bit
- The whole physical register address space has been moved to 0xfxxxxxxx
- The pinctrl setup has changed
- The clock tree is different enough to use a different driver

The original chosen addresses conflict with the BL2 initialisation.
So far there was no issue with them but if we preload binaries in
RAM (ROMUSB boot) before running the BL2 they get corrupted by the
execution of BL2 init.
If we load them around 0x08000000, there is no such issue.

Rework the board SYS_BOARD, SYS_VENDOR and SYS_CONFIG_NAME setup by moving
the board Kconfig into the mach-meson Kconfig to make it easier to add

We should use a macro rather than hard-coding the SPL prompt to 'spl'
since the code can be used by TPL too. Add a macro that works for both

This allows TPL to use the same code without printing confusing messages.
Note that the string is lower case ('spl', 'tpl') which is a change from
previously.

At present there is no standard way in U-Boot to pass information from SPL
to U-Boot proper. But sometimes SPL wants to convey information to U-Boot
that U-Boot cannot easily figure out. For example, if SPL sets up SDRAM
then it might want to pass the size of SDRAM, or the location of each
bank, to U-Boot proper.
Add a new 'bloblist' feature which provides this. A bloblist is set up in
the first phase of U-Boot that runs (i.e. TPL or SPL). The location of
this info may be in SRAM or CAR (x86 cache-as-RAM) or somewhere else.
Information placed in this region is preserved (with a checksum) through
TPL and SPL and ends up in U-Boot. At this point it is copied into SDRAM
so it can be used after relocation.
