cdc033136e samsung: Drop board_enable_audio_codec()
This function is not needed now since the audio codecs have been converted
to proper drivers. The codec-enable GPIO is handled there.

9cd97c5b04 ARM: Samsung: Add Exynos5422-based Odroid HC2 support
Odroid HC2 board is based on Odroid XU4 board, like the Odroid HC1.

The linux kernel does not provide a hc2 DTB so the hc1 DTB is also used
for the Odroid HC2.

Resend because MUA changed whitespace.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.

7090ead3f2 ARM: Samsung: Add Exynos5422-based Odroid HC1 support
Odroid HC1 board is based on Odroid XU4 board, but it has no HDMI,
no eMMC, no build-in USB3.0 hub, no extension port pins, and no GPIO
button. USB3.0 ports are used for build-in JMicron USB to SATA bridge
and Gigabit R8152 ethernet chips. HC1 uses only passive cooling.

This patch also updates Odroid's ADCmax array and reduces ADC tolerance
to 1% to ensure that XU4 and HC1 revisions are properly detected.

I've tested this with XU3, XU3-lite, XU4 and HC1 boards. In case of my test
boards I got following values from ADC register: 372, 370, 1281 and 1313.

9b643e312d treewide: replace with error() with pr_err()
U-Boot widely uses error() as a bit noisier variant of printf().

This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:

  # define __compiletime_error(message) __attribute__((error(message)))

This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux.  (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)

Let's convert error() into now treewide-available pr_err().

Done with the help of Coccinelle, excluing tools/ directory.

The semantic patch I used is as follows:

// <smpl>
@@@@
-error
+pr_err
 (...)
// </smpl>

00caae6d47 env: Rename getenv/_f() to env_get()
We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.

Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.

701e740f59 exynos5: Don't potentially undervoltage the CPU
For snow when chainloading u-boot the CPU seems to be running at full
speed. The lower CPU voltage seems to be ok for u-boot, but when booting
linux (bringing up all cores) I'm seeing random crashes.

Bump the voltage up to a level that's safe for all cpu frequencies.

1611c8cbcf exynos5-dt-types: add board detection for Odroid XU3/XU3L/XU4.
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

c65dc7d874 exynos: Add common board code for exynos5 boards that use device tree
Some boards use device tree for almost all board-specific configuration.
They therefore do not need their own separate board code, but can all use
the same version. Add a common version of the board code. It uses the
PMIC, regulator and video bridge uclasses. This will support smdk5250,
smdk5420, snow, spring, pit and pi.
