Seaboard and Ventana are very similar boards, and so share the seaboard.c
board file. The one difference needed so far is detected at run-time by
calling machine_is_ventana(). This bloats the Ventana build with code
that is never used. Switch to detecting Ventana at compile time to remove
bloat. This shaves ~5K off the SPL size on Ventana, and makes the SPL fit
within the max size.

For Tegra, the SPL and main U-Boot are concatenated together to form a
single memory image. Hence, the maximum SPL size is the different in
TEXT_BASE for SPL and main U-Boot. Instead of manually calculating
SPL_MAX_SIZE based on those two TEXT_BASE, which can lead to errors if
one TEXT_BASE is changed without updating SPL_MAX_SIZE, simply perform
the calculation automatically.

Add an ASSERT() to u-boot.lds to detect an SPL that doesn't fit within
SPL_TEXT_BASE..SPL_MAX_SIZE.
Different .lds files implement this check in two possible ways:
1) An ASSERT() like this
2) Defining a MEMORY region of size SPL_MAX_SIZE, and re-directing all
linker output into that region. Since u-boot.lds is used for both
SPL and main U-Boot, this would entail only sometimes defining a
MEMORY region, and only sometimes performing that redirection, and
hence option (1) was deemed much simpler, and hence implemented.
Note that this causes build failures at least for NVIDIA Tegra Seaboard
and Ventana. However, these are legitimate; the SPL doesn't fit within
the required space, and this does cause runtime issues.

Port USB1 on Whistler is intended as a device port for USB recovery.
Whistler's DT currently contains an alias for this USB port, even though
Whistler's config doesn't enable multiple USB controllers, so the alias
is unused. Remove the unused alias for consistency for now. Similar,
explicitly disable the port in the device tree too.

The device tree already contains the required configuration for both the
USB1 and USB3 ports. Enable the required configuration options to enable
both these ports, which in turn allows the USB1 port to be used.
Note that on a true Seaboard, this port is typically used as a device
port hosting Tegra's USB recovery protocol. However, on the Springbank
derivative, this port is the only external USB port, so we enable it as
a host port so that USB peripherals may be used. Enabling this port in
U-Boot as a host port doesn't prevent the port from reverting to a
device port when the CPU is reset into recovery mode.

Currently, Tegra's default environment uses non-standard variables to define
where boot scripts should load the kernel, FDT, and initrd. This change both
changes the variable names to match those described in U-Boot's README, and
shuffles their values around a little so that the values make a little more
sense; see comments in the patch for rationale behind the values chosen.
Note that this patch does remove the old non-standard variable "fdt_load" from
the default environment, so this patch requires people to change their boot
scripts.

This define indicates the size of the memory region where it is safe
to place data passed to the Linux kernel (ATAGs, DTB, initrd). The
value needs to be:
a) Less than or equal to RAM size.
b) Small enough that the area is not within the kernel's highmem region,
since the kernel cannot access ATAGs/DTB/initrd from highmem.
c) Large enough to hold the kernel+DTB+initrd.
256M seems large enough for (c) in most circumstances, and small enough
to satisfy (a) and (b) across any possible Tegra board. Note that the
user can override this value via environment variable "bootm_mapsize"
if needed.
The advantage of defining BOOTMAPSZ is that we no longer need to define
variable fdt_high in the default environment. Previously, we defined
this to prevent the DTB from being relocated to the very end of RAM,
which on most Tegra systems is within highmem, and hence which would
cause boot failures. A user can still define this variable themselves
if they want the FDT to be either left in-place wherever loaded, or
copied to some other specific location. Similarly, there should no
longer be a strict requirement for the user to define initrd_high if
using an initrd.

For Non-Nvidia boards to include newly added features (like emc clock
scaling) it would be necessary to add each feature to their own board
Makefile. This is because currently the top Makefile automaticly includes
these features only for Nvidia boards.
This patch adds a simple Makefile include so all new features become
available for non-Nvidia board vendors.

Update the linker script to explicitly include these. Without this

the sections do end up being included, but __bss_end__ gets set to the

The woodburn board is based on the MX35 SOC.
Support for both external (NOR) and internal
(SD Card) boot mode are added. It uses the

mode.
The following peripherals are supported:
- Ethernet (FEC)
- SD Card
- NAND (512 MB)
- NOR Flash
In the internal boot mode, a simple imximage header
is generated to set the address in internal RAM
where the SOC must copy the SPL code. The initial setup
is then demanded to the SPL itself.
