When U-Boot is run from another boot loader, much of the low-level init
needs to be skipped.
Add a flag for this and adjust ll_boot_init() to use it.

It is useful to be able to boot the same x86 image on a device with or
without a first-stage bootloader. For example, with chromebook_coral, it
is helpful for testing to be able to boot the same U-Boot (complete with
FSP) on bare metal and from coreboot. It allows checking of things like
CPU speed, comparing registers, ACPI tables and the like.
When U-Boot is not the first-stage bootloader much of this code is not
needed and can break booting. Add checks for this to the FSP code.
Rather than checking for the amount of available SDRAM, just use 1GB in
this situation, which should be safe. Using 2GB may run into a memory
hole on some SoCs.

Move this code to a generic location so that we can test it with sandbox.

The current code uses an address but a pointer would result in fewer

When moving the PHYLIB PHY drivers around in Kconfig we did not at the

platforms.

Currently generic-asm-offsets.h and asm-offsets.h are generated based
on U-Boot proper config options. The same asm-offsets headers are used
for building U-Boot SPL/TPL, which causes potential offset mismatch if
U-Boot proper has different config options from U-Boot SPL/TPL.
This commit adds:
spl/include/generated/(generic-)asm-offsets.h
tpl/include/generated/(generic-)asm-offsets.h
spl/include/generated/(generic-)asm-offsets.h is generated if
CONFIG_SPL=y, and included when building SPL.
tpl/include/generated/(generic-)asm-offsets.h is generated if
CONFIG_TPL=y, and included when building TPL.
They are created before Kbuild descends into SPL/TPL object directories
and builds $(obj)/dts/dt-platdata.o because $(obj)/dts/dt-platdata.c
includes a bunch of headers.
Prepend -I$(obj)/include to $(UBOOTINCLUDE) so (generic-)asm-offsets.h
is searched in {spl,tpl}/include/generated/.

building the same target, except for the default DT. The default DT is
however only a detail, as the actual DT to be used to configure U-Boot

not meaningful. Unify each three defconfigs per board to reduce the

Power on/off the PHYs to enable power to the USB ports, fixing USB support
on Khadas VIM3/VIM3L boards.
The G12A USB complex has at least 2 USB2 PHYs, but one is muxed between the
DWC2 and DWC3 controller and the other one directly connected to the DWC3
controller. The USB3+PCIe combo PHY is muxed between the DWC3 controller
and a DW-PCIE controller.
All PHYs are optional, but it's type (usb2/usb3) and position are important
to determine it's capabilities, thus they are stored in a fixed size
array and the phy-name determines it's position, it's position determining
it's type and functionnalities.
This is why we need to loop over the array to power on all the DT provided
PHYs.

Here we introduce new development platfrom for ARC: HSDK 4xD.
That's pretty much the same base-board as in HSDK but with
very recent quad-core ARC HS47D in the ASIC.
Thus we try to re-use existing code as much as possible while
inevitably add some pieces needed for the new ASIC.
Also we drop selection of bounce buffers on AXS10x
as there's no use of them any longer.
At this point LLVM-7 is rather old. Switch over to LLVM-10 to enable
some amount of CI coverage with newer compilers.
