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
allows for boards without Vbus gpio-s.

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.

Automatic booting using an extlinux.conf file requires various environment

This commit adds:
- arch/${ARCH}/Kconfig
provide a menu to select target boards
- board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
set CONFIG macros to the appropriate values for each board
- configs/${TARGET_BOARD}_defconfig
default setting of each board
(This commit was automatically generated by a conversion script
based on boards.cfg)
In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.
But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.
