Since CONFIG_VIDEO_AMBA is not set by any board, it does not seem
to be used, so remove it since there is no way to (compile) test it.

Jeroen,
How will this all go in? Do you expect Anatolij to take it in via the main repo (u-boot.git/master)?
LGTM, BTW

I am not sure I understand exactly what you mean, but yes there
are some conflicts awaiting. 2 pending drivers and another lcd
cleanup patch. And yes I think it is easier to rebase those then to
rebase this and Wolfgang's patch (if that is what you're asking),
since the variables are deleted step by step. So simply not adding
them is easier then getting rid of them again. The other lcd cleanup
is smaller. I don't know how much trouble the board config changes
will cause.
To not break the pending drivers a new version of
http://patchwork.ozlabs.org/patch/212378/ is needed though, since
it does not apply after this patch set. Since that patch contains 2 lines,
that should be easy (or can be manually merged by Anatolij).
But it is up to Anatolij, how this actually goes in and to which branch.
Regards,
Jeroen

That's all I was asking - if I would be responsible for the tegra portion of the patch, or if it would all go in to TOT master.
I'll take your response to mean that I have nothing to do here for the u-boot-tegra repo.

Since the lcd code was compiled unconditionally in arch also
add CONFIG_MPC8XX_LCD to the boards using this driver.

To: u-boot
Since the lcd code was compiled unconditionally for pxa also add
CONFIG_PXA_LCD to the boards using this framebuffer. Since the
driver/video contains video and lcd driver add lcd to the name
to make clear it belongs to common/lcd.c.

console_col, console_row, lcd_line_length, lcd_console_address had
to be declared in board / driver specific code, but were not actually
used there. Get rid of the global variables.

- Make the brackets of the function calls more consistent
- Remove really unnecessary brackets
- Removes the extern from the function definitions
- Remove curly brackets from single line statements
- Remove lcd_setmem proto since it is already in common.h
- Don't init globals to 0

Hello.

I used the driver on the nhk8815. But actually it looks like the
"later patch in this set", that my commit message references, was not
merged. I remember I used it in 32-bit mode and had to hack some
things to make it work, inluding a fater memcopy as scrolling was very
slow.
I don't think I can resurrect my nhk8815 device any soon, and it looks
like nobody else is using this logic cell, so I'm fine removing the
driver.

As mentioned in http://lists.denx.de/pipermail/u-boot/2013-January/143459.html
there does not seem to be a good reason why the frame buffer driver
provide the variables for the lcd internal logic. So lets just remove it.
If there is any good reason for a framebuffer driver to "call up" it should
do so by a function call and not change the lcd its internal state (and
there is actually none doing so at the moment).
This patchset first removes unused drivers and places drivers useing
common/lcd.c in drivers/video. Then removes the unneeded globals and
thereafter finishes with some cleanups.
This patch goes after http://patchwork.ozlabs.org/patch/209692/
"common/lcd.c: cleanup use of global variables"
Version 2:
Marek Vasut <marex@denx.de>: use format-patch -M to detect moves
Adjust the commit message not to exceed the max line length
Fix malformed email address.
check-patch clean (adjusted a space in patch 6)
remove bouncing email addresses and add acks
patch 7 and 10 are unchanged and not reposted

Since the lcd code was compiled unconditionally in arch also
add CONFIG_MPC8XX_LCD to the boards using this driver.

Since the lcd code was compiled unconditionally for pxa also add
CONFIG_PXA_LCD to the boards using this framebuffer. Since
driver/video contains video and lcd drivers, add lcd to the name
to make clear it belongs to common/lcd.c.

console_col, console_row, lcd_line_length, lcd_console_address had
to be declared in board / driver specific code, but were not actually
used there. Get rid of the global variables.
for completeness, the ack of Bo Shen is for the atmel part
