The initial environment is linked to the u-boot binary. Modifying the
environment from User Space with the env tools requires that the tools
are always built together with the bootloader to be sure that they
contain the initial environment in case no environment is stored into
persistent storage or when a board boots with just the default
environment. This makes difficult for distros to provide a general
package to access the environment. A simpler way is if the tools are
generic for all boards and a configuration file is given to provide the
initial environment.
The patch just generates the initial environment by extracting it from
the compiled object. This file can then be used for tools in user space
to initialize the environment.

HVC call makes use of 6 mandatory arguments rather than 7 in the same way
as SMC calls. The 7th argument is optional (Client ID) for both HVC and
SMC but is implemented as 16-bit parameter and register R7 or W7. The aim
of this patch is just fix compilation error due to an invalid asm code in
the HVC call so that's why the 7th argument is removed.
The issue does not report any error in a normal build as hvc_call is not
used at all and is optimized by the compiler. Using -O0 triggers the
error so the patch is intended to fix issues on a ongoing effor to build
U-Boot with -O0.

It works perfectly fine to boot an Android boot.img with bootm command
followed by an explicit address argument that holds the image. But if
we have boot.img downloaded into default 'loadaddr', and then boot it
using bootm command without the address argument, we will run into
problem, because U-Boot fails to find ramdisk and fdt (second area) in
boot.img.
The current Android image support assumes there is always an address
argument on bootm command. However just like booting any other images,
'loadaddr' should be used when address argument is missing from bootm
command. It patches boot_get_ramdisk() and boot_get_fdt() a bit to
support this quite common usage of bootm command for Android image.

Merge tag 'u-boot-atmel-2019.07-b' of git://git.denx.de/u-boot-atmel
Second set of u-boot-atmel features and fixes for 2019.07 cycle
This fixes a disconnect issue detected with fastboot command, when using
dwc2 driver.
- On u-boot side:
uboot>$ fastboot 0
- On USB host PC side, few seconds after
PC>$ fastboot reboot # Get stuck, uboot target never reboots
By enabling DEBUG_ISR logs, the bus suspend interrupt is seen before the
PC command has been issued. When the USB bus suspend occurs, there's a HACK
that disables the fastboot (composite driver). Here is the call stack
upon USB bus suspend:
- dwc2_handle_usb_suspend_intr()
- dev->driver->disconnect()
- composite_disconnect()
- reset_config()
- f->disable()
- fastboot_disable()
- usb_ep_disable(f_fb->out_ep);
- usb_ep_disable(f_fb->in_ep);
.. other disable calls.
When the resume interrupt happens, everything has been disabled, then
nothing happens. fastboot command gets stuck on HOST side.
Remove original HACK, that disconnects the composite driver upon
USB bus suspend. Implement disconnect detection instead:
- check GINTSTS OTG interrupt
- read GOTGINT register
- check GOTGINT, SesEndDet bit (e.g. session end)
This is inspired by what is implemented currently in Linux dwc2 driver.

Our R-Car3 Android userspace relies on the output of 'fastboot
getvar platform' and U-Boot currently is not able to handle it:
host $> fastboot getvar platform
getvar:platform FAILED (remote: Variable not implemented)
finished. total time: 0.001s
We either have the option of adding 'fastboot.platform' variable
to the default/saved environment as a workaround or add proper
'fastboot getvar platform' support in U-Boot via this patch.
In the latter case, other platforms can benefit from it too.
Note that R-Car3 already exports 'platform' environment variable via
