usb_hub_power_on() currently waits for the maximum of (a) the hub port's
power output to become good, (b) the max time the USB specification
allows a device to take to connect.
However, these two operations must occur in series rather than in
parallel. First, the power supply ramps up to the level required to
power the USB device, and then the device may take a certain amount of
time to connect (assert D+/D- pullups).
Related, the maximum time that a device has to assert pullups is 1s not
100ms.
This is explained in "Connect Timing ECN.pdf", itself part of
usb_20_042814.zip from www.usb.org.

bootdelay_process() never returns in some circumstances, whichs makes the
control flow confusing. Change it so that the decision about how to execute
the boot command is made in the main_loop() code, so it is easier to follow.
Move CLI stuff to cli.c.

using UBI and DM together leads in compiler error, as
both define a "struct device", so rename "struct device"
in include/dm/device.h to "struct udevice", as we use
linux code (MTD/UBI/UBIFS some USB code,...) and cannot
change the linux "struct device"

The new atmelimage converts a machine code BLOB to bootable ROM image. Atmel
ROM has no sophisticated image format, it only checks the first 7 ARM vectors.
The vectors can contain valid B or LDR opcodes, the 6'th vector contains the
image size to load.
Additionally the PMECC header can be written by the atmelimage target. The
parameters must be given via the -n switch as a coma separated list. For
example:
mkimage -T atmelimage \
-n usePmecc=1,sectorPerPage=4,sectorSize=512,spareSize=64,eccBits=4,eccOffset=36 \
-d spl/u-boot-spl.bin boot.bin
A provided image can be checked for correct header setup. It prints out the
PMECC header parameters if it has one and the 6'th interrupt vector content.

This sub-command adds support for the RPMB partition of an eMMC:
* mmc rpmb key <address of the authentication key>
Programs the authentication key in the eMMC This key can not
be overwritten.
* mmc rpmb read <address> <block> <#count> [address of key]
Reads <#count> blocks of 256 bytes in the RPMB partition
beginning at block number <block>. If the optionnal
address of the authentication key is provided, the
Message Authentication Code (MAC) is verified on each
block.
* mmc rpmb write <address> <block> <#count> <address of key>
Writes <#count> blocks of 256 bytes in the RPMB partition
beginning at block number <block>. The datas are signed
with the key provided.
* mmc rpmb counter
Returns the 'Write counter' of the RPMB partition.
The sub-command is conditional on compilation flag CONFIG_SUPPORT_EMMC_RPMB

The command "time" shows the execution time of the command given
to the argument, like this:
time: 45.293 seconds, 45293 ticks
Since we adopted CONFIG_SYS_HZ = 1000 for all boards,
we always have a simple formula: "1 tick = 0.0001 second".
Showing ticks looks almost redundant.

This patch contains an implementation of the fastboot protocol on the
device side and documentation. This is based on USB download gadget
infrastructure. The fastboot function implements the getvar, reboot,
download and reboot commands. What is missing is the flash handling i.e.
writting the image to media.
v3 (Rob Herring):
This is based on http://patchwork.ozlabs.org/patch/126798/ with the
following changes:
- Rebase to current mainline and updates for current gadget API
- Use SPDX identifiers for licenses
- Traced the history and added missing copyright to cmd_fastboot.c
- Use load_addr/load_size for transfer buffer
- Allow vendor strings to be optional
- Set vendor/product ID from config defines
- Allow Ctrl-C to exit fastboot mode
v4:
- Major re-write to use the USB download gadget. Consolidated function
code to a single file.
- Moved globals into single struct.
- Use puts and putc as appropriate.
- Added CONFIG_USB_FASTBOOT_BUF_ADDR and CONFIG_USB_FASTBOOT_BUF_SIZE to
set the fastboot transfer buffer.
v5:
- Add CONFIG option documentation to README
- Rebase using new downloader registration

This patch adds support for the Android boot-image format. The header
file is from the Android project and got slightly alterted so the struct +
its defines are not generic but have something like a namespace. The
header file is from bootloader/legacy/include/boot/bootimg.h. The header
parsing has been written from scratch and I looked at
bootloader/legacy/usbloader/usbloader.c for some details.
The image contains the physical address (load address) of the kernel and
ramdisk. This address is considered only for the kernel image.
The "second image" defined in the image header is currently not
supported. I haven't found anything that is creating this.
v3 (Rob Herring):
This is based on http://patchwork.ozlabs.org/patch/126797/ with the
following changes:
- Rebased to current mainline
- Moved android image handling to separate functions in
common/image-android.c
- s/u8/char/ in header to fix string function warnings
- Use SPDX identifiers for licenses
- Cleaned-up file source information:
android_image.h is from file include/boot/bootimg.h in repository:
https://android.googlesource.com/platform/bootable/bootloader/legacy
The git commit hash is 4205b865141ff2e255fe1d3bd16de18e217ef06a
usbloader.c would be from the same commit, but it does not appear
to have been used for any actual code.
v4:
- s/andriod/android/
- Use a separate flag ep_found to track if the entry point has been set
rather than using a magic value.
