Hans de Goede fb75d972ea sunxi: video: Force h/vsync active high when using ext. vga dac on some boards
On both my A13-OLinuxIno and my A13-OLinuxIno-Micro, the vga output gives an
unstable image when active low v or hsync is used.

The problem seems to be specific to the OLinuxIno A13 (normal & micro)
boards. I've just looked up the schematics and they use an opendrain driver
for the vga sync lines, and with sync pulses it is the logical high->low
edge of the pulse which counts for the timing, which with an active low
sync is being driven by the pull-up, and that simply seems to not drive
it hard enough to get a stable image.

So force v and hsync active high on these boards. independent of what the
modeline says. This fixes the unstable image.

Hans de Goede 40d0cdda3e sunxi: Remove CONFIG_TARGET_FOO for sun5i and sun7i boards
CONFIG_TARGET_FOO was only used in board/sunxi/Makefile to select the
dram config for sun5i and sun7i boards and in board/sunxi/gmac.c for some
special handling of the bananapi/bananapro (both sun7i), all sun5i and sun7i
boards have been moved over to using a single dram_sun5i_autoconfig file,
and the tx clk delay handling for the Banana boards now has its own Kconfig.

IOW nothing is using CONFIG_TARGET_FOO anymore, so remove it.

Hans de Goede e1a0888ed2 sunxi: Convert sun5i boards to use auto dram configuration
Currently we've separate detailed dram settings for all sun5i boards, this
moves them over to using auto dram configuration so that we can get rid of
all the per board dram_foo.c files.

This has been tested on a A10s-Olinuxino, A13-Olinuxino, A13-OlinuxinoM,
mk802-a10s and r7-tv-dongle board.

Hans de Goede 5ef5263b9a sunxi: A13-OLinuXino defconfigs: Enable VGA output, add lcd-mode for 7" LCD
Enable VGA output on the A13-OLinuXino and A13-OLinuXinoM now that we've
support for it.

Also add LCD timing and gpio info for the Olimex 7" LCD module. We can safely
put this in the default config on this boards, since by default we will always
use VGA, and the LCD timing info will only get used if the user explicitly
sets monitor=lcd in the video-mode env. variable.

Luc Verhaegen 7f2c521f90 sunxi: video: Add cfb console driver for sunxi
This adds a fixed mode hdmi driver for the sunxi platform. The fixed
mode is a relatively safe 1024x768, more complete EDID handling is
currently not provided. Only HDMI is supported today.

This code is enabled when HPD detects an attached monitor.

Current config is such that 8MB is shaved off at the top of the RAM.
This avoids several memory handling issues, most significant is the fact
that on linux on ARM you are not allowed to remap known RAM as IO. A
clued in display driver will be able to recycle this reserved RAM in
future though.

cfbconsole was chosen as it provides the most important functionality: a
working u-boot console, allowing for the debugging of certain issues
without the need for a UART.

Add proper Kconfig options to select the usb Vbus gpio-s, besides moving to
Kconfig being the right thing to do, an added advantage of this is that it

Ian Campbell d9a2047641 sunxi: kconfig: Introduce CONFIG_TARGET_<BOARD>
This was done automatically with the following bits of scripting.

The Kconfig choice content was generated with this script snippet:
    for i in $(git grep -l CONFIG_ARCH_SUNXI configs/*) ; do
        TARGET=$(sed -n -e 's/CONFIG_SYS_EXTRA_OPTIONS="\([^,"]\+\).*/\1/p' $i);
        MACH=$(sed -n -e 's/.*CONFIG_\(MACH_SUN.I\)=./\1/p' $i)
        echo "config TARGET_$TARGET"
        echo "	bool \"$TARGET\""
        echo "	depends on $MACH"
        echo
    done

defconfigs were updated with a sed script (t):
    # Extract board from first entry of CONFIG_SYS_EXTRA_OPTIONS,
    /^CONFIG_SYS_EXTRA_OPTIONS/ {
        s/^\(CONFIG_SYS_EXTRA_OPTIONS="\)\([^,"]\+\),\?\(.*\)/\1\3\nCONFIG_TARGET_\2=y/;

        # Print and delete first line (CONFIG_SYS_EXTRA_OPTIONS), leaving
        # CONFIG_TARGET_<BOARD> in pattern space
        P;D;
    };

    # Move CONFIG_TARGET_<BOARD> to hold space
    /^CONFIG_TARGET/{h;n}

    # Print CONFIG_TARGET_<BOARD> after CONFIG_MACH_<SOC> in either SPL or
    # normal mode.
    /^CONFIG_MACH/{p;g;p;n};
    /^\+S:CONFIG_MACH/{p;g;s/^CONFIG_TARGET/+S:&/;p;n};

    # Print any remaining lines normally
    p;
Run as:
    sed -i -n -f t $(git grep -l CONFIG_ARCH_SUNXI configs/*)
and then manually removing the one instance of CONFIG_SYS_EXTRA_OPTIONS="" from
Colombus_defconfig

board/sunxi/Makefile was updated with:
    sed -e 's/^\(obj-\$(CONFIG_\)\(.*\)\().*+= dram_.*\)/\1TARGET_\2\3/g' board/sunxi/Makefile
and manually retabbing a few lines to line up again.

The board descriptions could certainly be improved.
