Update several boards to use driver model for video. This involves changes
to the EDP and FIMD (frame buffer) drivers. Existing PWM, simple-panel and
pwm-backlight drivers are used. These work without additional configuration
since they use the device tree settings in the same way as Linux.
Boards converted are:
- snow
- spring
- peach-pit
- peach-pi
All have been tested. Not converted:
- MIPI display driver
- s5pc210_universal
- smdk5420
- smdk5250
- trats
- trats2

This commit adds additional file with implementation of board
detection code for Odroid-XU3/XU4.
The detection depends on compatible found in fdt:
- "samsung,exynos5" - uses Exynos5 generic code
- "samsung,odroidxu3" - try detect XU3 revision
There are few revisions of Odroid XU3/XU4, each can be detected
by checking the value of channel 9 of built-in ADC:
Rev ADC Board
0.1 0 XU3 0.1
0.2 372 XU3 0.2 | XU3L - no DISPLAYPORT
0.3 1280 XU4 0.1
The detection code depends on the ADC+10% value.
Implementation of functions:
- set_board_type() - read ADC and set type
- get_board_rev() - returns board revision: 1..3
- get_board_type() - returns board type string
Additional functions with return values of bool:
- board_is_generic() - true if found compatible "samsung,exynos5"
but not "samsung,odroidxu3"
- board_is_odroidxu3() - true if found compatible "samsung,odroidxu3"
and one of XU3 revision.
- board_is_odroidxu4() - true if found compatible "samsung,odroidxu3"
and XU4 revision.
After I2C controller init, the get_board_type() can check
if the XU3 board is a "Lite" variant, by probing chip
0x40 on I2C0 (INA231 - exists only on non-lite).
This is useful for setting fdt file name at misc_init_r().
Enabled configs:
- CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG
- CONFIG_ODROID_REV_AIN
- CONFIG_REVISION_TAG
- CONFIG_BOARD_TYPES

In the "Getting Started with Coccinelle - KVM edition" presentation that
has been held by Julia Lawall at the KVM forum 2015 (see the slides at
http://events.linuxfoundation.org/sites/events/files/slides/tutorial_kvm_0.pdf),
she pointed out some bad return value checks in U-Boot that can be
detected with Coccinelle by using the following config file:
@@
identifier x,y;
identifier f;
statement S;
@@
x = f(...);
(
if (x < 0) S

if (

Spring is the first ARM-based HP Chromebook 11. It is similar to snow
and it uses the same Samsung Exynos5250 chip. But has some unusual

by adding a device tree and a few lines of configuration.

This commit adds example scripts of boot.scr:
- bootzimg.cmd - check if dtb exists and boot zImage
- autoboot.cmd - check which image exists: Image.itb, zImage or uImage
and optionally load fdt file for u/zImage
The blank spaces are added to improve readability and can be removed
before use mkimage.
Required U-Boot environment variables: $boardname, $fdtfile, $console,
$mmcbootdev, $mmcbootpart, $mmcrootdev, $mmcrootpart, $rootfstype.
Making boot.scr from file.cmd:
mkimage -C none -A arm -T script -d file.cmd boot.scr
The Odroid XU3 default environment is ready for those boot scripts and
the right script can be loaded by DFU.

As mentioned in the previous commit, adding default values in each
Kconfig causes problems because it does not co-exist with the
"depends on" syntax. (Please note this is not a bug of Kconfig.)
We should not do so unless we have a special reason. Actually,
for CONFIG_DM*, we have no good reason to do so.
Generally, CONFIG_DM is not a user-configurable option. Once we
convert a driver into Driver Model, the board only works with Driver
Model, i.e. CONFIG_DM must be always enabled for that board.
So, using "select DM" is more suitable rather than allowing users to
modify it. Another good thing is, Kconfig warns unmet dependencies
for "select" syntax, so we easily notice bugs.
Actually, CONFIG_DM and other related options have been added
without consistency: some into arch/*/Kconfig, some into
board/*/Kconfig, and some into configs/*_defconfig.
This commit prefers "select" and cleans up the following issues.
[1] Never use "CONFIG_DM=n" in defconfig files
It is really rare to add "CONFIG_FOO=n" to disable CONFIG options.
It is more common to use "# CONFIG_FOO is not set". But here, we
do not even have to do it.
Less than half of OMAP3 boards have been converted to Driver Model.
Adding the default values to arch/arm/cpu/armv7/omap3/Kconfig is
weird. Instead, add "select DM" only to appropriate boards, which
eventually eliminates "CONFIG_DM=n", etc.
[2] Delete redundant CONFIGs
Sandbox sets CONFIG_DM in arch/sandbox/Kconfig and defines it again
in configs/sandbox_defconfig.
Likewise, OMAP3 sets CONFIG_DM arch/arm/cpu/armv7/omap3/Kconfig and
defines it also in omap3_beagle_defconfig and devkit8000_defconfig.
