As best I can tell, CONFIG_SYS_LOAD_ADDR and CONFIG_LOADADDR/$loadaddr
serve essentially the same purpose. Roughly, if a command takes a load
address, then CONFIG_SYS_LOAD_ADDR or $loadaddr (or both) are the default
if the command-line does not specify the address. Different U-Boot
commands are inconsistent re: which of the two default values they use.
As such, set the two to the same value, and move the logic that does this
into tegra-common-post.h so it's not duplicated. A number of other non-
Tegra boards do this too.
The values chosen for these macros are no longer consistent with anything
in MEM_LAYOUT_ENV_SETTINGS. Regain consistency by setting $kernel_addr_r
to CONFIG_LOADADDR. Older scripts tend to use $loadaddr for the default
kernel load address, whereas newer scripts and features tend to use
$kernel_addr_r, along with other variables for other purposes such as
DTBs and initrds. Hence, it's logical they should share the same value.
I had originally thought to make the $kernel_addr_r and CONFIG_LOADADDR
have different values. This would guarantee no interference if a script
used the two variables for different purposes. However, that scenario is
unlikely given the semantic meaning associated with the two variables.
The lowest available value is 0x90200000; see comments for
MEM_LAYOUT_ENV_SETTINGS in tegra30-common-post.h for details. However,
that value would be problematic for a script that loaded a raw zImage to
$loadaddr, since it's more than 128MB beyond the start of SDRAM, which
would interfere with the kernel's CONFIG_AUTO_ZRELADDR. So, let's not do
that.
The only potential fallout I could foresee from this patch is if someone
has a script that loads the kernel to $loadaddr, but some other file
(DTB, initrd) to a hard-coded address that the new value of $loadaddr
interferes with. This seems unlikely. A user should not do that; they
should either hard-code all load addresses, or use U-Boot-supplied
variables for all load addresses. Equally, any fallout due to this change
is trivial to fix; simply modify the load addresses in that script.

The ehci driver model code for finding the first upstream usb-2 hub before

1) "if (!ttdev->speed != USB_SPEED_HIGH)" does not work because the '!'
takes presedence over the '!=' this should simply be
"if (ttdev->speed == USB_SPEED_HIGH)"
2) It makes ttdev point to the first upstream usb-2 hub, but ttdev should
point to the last usb-1 device before the first usb-2 hub (when going
upstream from the device), as ttdev is used to find the port of the
first usb-2 hub to which the the last usb-1 device is connected.
3) parent_devnum however should be set to the devnum of the first usb-2
hub, so we need to keep pointers around to both usb_device structs.
To complicate things further during enumeration usb_device.dev will point
to the parent udevice, where as during normal use it will point to
the actual udevice, we must handle both cases correctly.
