On popular request make the display driver from T20 work on T30 as
well. Turned out to be quite straight forward. However a few notes
about some things encountered during porting: Of course the T30 device
tree was completely missing host1x as well as PWM support but it turns
out this can simply be copied from T20. The only trouble compiling the
Tegra video driver for T30 had to do with some hard-coded PWM pin
muxing for T20 which is quite ugly anyway. On T30 this gets handled by
a board specific complete pin muxing table. The older Chromium U-Boot
2011.06 which to my knowledge was the only prior attempt at enabling a
display driver for T30 for whatever reason got some clocking stuff
mixed up. Turns out at least for a single display controller T20 and
T30 can be clocked quite similar. Enjoy.

Move this out of the common header and include it only where needed. In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly. Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

Try to maintain some consistency between these variables by using _plat as

This name is far too long. Rename it to remove the 'data' bits. This makes
it consistent with the platdata->plat rename.

We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private
or platform data).
Rename some of the latter variables to end with 'plat' for consistency.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

Use the _ptr suffixed variant instead of casting. Also, convert it to
dev_read_addr_ptr(), which is safe to CONFIG_OF_LIVE.
One curious part is an error check like follows in
drivers/watchdog/omap_wdt.c:
priv->regs = (struct wd_timer *)devfdt_get_addr(dev);
if (!priv->regs)
return -EINVAL;
devfdt_get_addr() returns FDT_ADDR_T_NONE (i.e. -1) on error.
So, this code does not catch any error in DT parsing.
dev_read_addr_ptr() returns NULL on error, so this error check
will work.
I generated this commit by the following command:
$ find . -name .git -prune -o -name '*.[ch]' -type f -print | \
xargs sed -i -e 's/([^*)]*\*)devfdt_get_addr(/dev_read_addr_ptr(/'

Move this header out of the common header. Network support is used in
quite a few places but it still does not warrant blanket inclusion.
Note that this net.h header itself has quite a lot in it. It could be
split into the driver-mode support, functions, structures, checksumming,
etc.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.
In the end we will have:
1. dev_read_addr...() - works on devices, supports flat/live tree
2. devfdt_get_addr...() - current functions, flat tree only
3. of_get_address() etc. - new functions, live tree only
All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.
Note this involves changing some dead code - the imx_lpi2c.c file.

At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

We have standard drivers for panels and backlights which can do most of the
work for us. Move the tegra20 LCD driver over to use those instead of custom
code.
This patch includes device tree changes for the nvidia boards. I have only
been able to test seaboard. If this patch is applied, these boards will
also need to be synced with the kernel, and updated to use display-timings:

This prevents the following boot-time message on any board where only the
first DC is in use, yet the DC's DT node is enabled:
stdio_add_devices: Video device failed (ret=-22)
(This happens on at least Harmony, Ventana, and likely any other Tegra20
board with display enabled other than Seaboard).
The Tegra DC's DT node represents a display controller. It may itself
drive an integrated RGB display output, or be used by some other display
controller such as HDMI. For this reason the DC node itself is not
enabled/disabled in DT; the DC itself is considered a shared resource, not
the final (board-specific) display output. The node should instantiate a
display output driver only if the rgb subnode is enabled. Other output
drivers are free to use the DC if they are enabled and their DT node
references the DC's DT node. Adapt the Tegra display drivers' bind()
routine to only bind to the DC's DT node if the RGB subnode is enabled.
Now that the display driver does the right thing, remove the workaround
for this issue from Seaboard's DT file.

We have flipped CONFIG_SPL_DISABLE_OF_CONTROL. We have cleansing
devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear
away the ugly logic in include/fdtdec.h:
#ifdef CONFIG_OF_CONTROL
# if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL)
# define OF_CONTROL 0
# else
# define OF_CONTROL 1
# endif
#else
# define OF_CONTROL 0
#endif
Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute. It refers to
CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for
SPL.
Also, we no longer have to cancel CONFIG_OF_CONTROL in
include/config_uncmd_spl.h and scripts/Makefile.spl.

Instead of storing the computed line length in a local variable, store
it in the global lcd_line_length variable to make sure the LCD subsystem
can properly draw content for the display resolution.
This probably wasn't noticed yet because the only board where LCD
support is currently enabled is Seaboard, which runs at a 1366x768
resolution. As it happens this is the maximum resolution supported and
also the default that is used to initialize the framebuffer before the
configuration from DT is available.
