So far we did not support the BootROM based FEL USB debug mode on the
64-bit builds for Allwinner SoCs: The BootROM is using AArch32, but the
SPL runs in AArch64.
Returning back to AArch32 was not working as expected, since the RMR
reset into 32-bit mode always starts execution in the BootROM, but not
in the FEL routine.
After some debug and research and with help via IRC, the CPU hotplug
mechanism emerged as a solution: If a certain R_CPUCFG register contains
some magic, the BootROM will immediately branch to an address stored in
some other register. This works well for our purposes.
Enable the FEL feature by providing early AArch32 code to first save the
FEL state, *before* initially entering AArch64.
If we eventually determine that we should return to FEL, we reset back
into AArch32, and use the CPU hotplug mechanism to run some small
AArch32 code snippet that restores the initially saved FEL state.
That allows the normal AArch64 SPL build to be loaded via the sunxi-fel
tool, with it returning into FEL mode, so that other payloads can be
transferred via FEL as well.
Tested on A64, H5 and H6.

So far we used the separate mksunxiboot tool for generating a bootable
image for Allwinner SPLs, probably just for historical reasons.
Use the mkimage framework to generate a so called eGON image the

The new image type is called "sunxi_egon", to differentiate it

On the XEA board (imx28) one needs in the SPL support for GPIO, MMC and
SPI. Two last ones are necessary for booting the device. The GPIO support
allows deciding which medium will be used. For example the GPIO DTS node
(gpio@0 at imx28.dtsi) has pinctrl parent (pinctrl@80018000) for which we
don't need driver asigned for correct operation.
In the spl/dts/dt-platdata.c the gpio@0 has index 4 and its parent -
pinctrl@80018000 has index 5.
In the bind_drivers_pass() function (at drivers/core/lists.c) call to
device_bind_by_name() for `fsl_imx23_pinctrl` returns -2, which is
expected.
With current setup - when the SPL_OF_PLATDATA_PARENT=y
The gpio@0 node with index 4 is skipped as its parent with 5 is not yet
bound. It cannot be as we don't need and provide the driver for it.
As a result the gpio@0 is never bound and we end up with bricked board in
the SPL stage.
When CONFIG_SPL_OF_PLATDATA_PARENT is NOT set, all entries from
spl/dts/dt-platdata.c are scanned in ascending index order, so gpio@0 is
properly initialized. For `fsl_imx_pinctrl` we simply check 10 times if
the driver for is available (which is not) and exit.
As a result the GPIOs are initialized and can be used in early SPL stage.

Signed-off-by: Simon Glass <sjg@chromium.org>
Before expanding the scanning features any more, move this into a separate
file. This will make it easier to maintain in the future. In particular,
it reduces the size of dtb_platdata.py and allows us to add tests
specifically for scanning, without going through that file.
The pieces moved are the Driver class, the scanning code and the various
naming functions, since they mostly depend on the scanning results.
So far there is are no separate tests for src_scan. These will be added
as new functionality appears.
This introduces no functional change.

This has not been needed since parent information was added and we started

Previously we had to worry about nodes being output before those that they
depended on, thus causing build errors. So the current algorithm is
careful to output nodes in the right order.
We now use a different method for outputting phandles that does not
involve pointers. Also we plan to add a 'declarations' header file to
declare all drivers as 'extern'.
Update the code to drop the dependency checking and output in a simple
loop. This makes the output easier to follow since drivers are in order of
thier indices (0, 1, ...), which is also the order it appears in in the
linker list.

Rename generate_tables to generate_plat since it better describes what is

We could perhaps rename U_BOOT_DRIVER() to DM_DRIVER(), but this macro

This does not get a device (struct udevice *) but a struct driver_info *

the related macros.
Signed-off-by: Simon Glass <sjg@chromium.org>
The current macro is a misnomer since it does not declare a device
directly. Instead, it declares driver_info record which U-Boot uses at
runtime to create a device.
The distinction seems somewhat minor most of the time, but is becomes
quite confusing when we actually want to declare a device, with
of-platdata. We are left trying to distinguish between a device which
isn't actually device, and a device that is (perhaps an 'instance'?)
It seems better to rename this macro to describe what it actually is. The
macros is not widely used, since boards should use devicetree to declare
devices.
Rename it to U_BOOT_DRVINFO(), which indicates clearly that this is
declaring a new driver_info record, not a device.
