88fa34df9f stm32mp1: clk: add LDTC and DSI clock support
This patch add clk_enable/clk_disable/clk_get_rate support for
- DSI_PX
- LTDC_PX
- DSI_K (only get rate)

These clocks are needed for LTDC and DSI drivers with latest device tree.

af95a3e7c0 drivers: rtc: correct week day for mc146818
For qemu-x86 the date command produces wrong days of the week:
Date: 2018-07-06 (Saturday)    Time: 18:02:03
Date: 2018-07-07 (unknown day)    Time: 21:02:06

According to a comment in the Linux driver the mc146818 only updates the
day of the week if the register value is non-zero.

Sunday is 1, saturday is 7 unlike in U-Boot (see data sheet
https://www.nxp.com/docs/en/data-sheet/MC146818.pdf).

So let's use our library function to determine the day of the week.

57aa4d2066 env: Include bootdelay in environment if negative
The test for (CONFIG_BOOTDELAY >= 0) has been in U-Boot since the
beginning, but the meaning of it has changed over time. Allow the
default to be set for any value, including -ve ones. This allows
(for example) CONFIG_ENV_IS_NOWHERE to have values for bootdelay in
its compiled in environment.

The only thing this changes is where the default for bootdelay can be
fetched from; before this change you get a compiled in default, after
you'll pull it from the default value in the environment, but both values
will be the same. Also if there's a value set in the environment then
that will take precedence (as before).

f8c173b6a0 fs: btrfs: Fix wrong comparison in logical to physical mapping
The comparison
  logical > item->logical + item->length
in btrfs_map_logical_to_physical is wrong and should be instead
  logical >= item->logical + item->length
For example, if
  item->logical = 4096
  item->length = 4096
and we are looking for logical = 8192, it is not part of item (item is
[4096, 8191]). But the comparison is false and we think we have found
the correct item, although we should be searing in the right subtree.

This fixes some bugs I encountered.

73e9db22ab board/BuR/brppt1: implement more flexible boot process
With this commit we do:

- set the bootdelay in all brppt1 defconfigs to 0, this makes
development easier, since we can break into serial console.

- move CONFIG_BOOTCOMMAND from header file to defconfig

- introduce b_mode variable for selecting the final boot-target.
This b_mode represents the boot-switch, which can found on most b&r
targets. On the brppt1 this boot-switch is derived from some gpio and
the bootcounter within the RTC block, making it so possible to force
a boot-target (as example for repair-case).

- refactor the environment for booting new flexible way
primary we want to get some bootscr.img within the mass-storage,
this script then loads everything needed for the boot.
For legacy reason we implement the t30lgcy#x boot targets, booting the
already delivered linux-images.

- make space for the cfgscr within mtdparts on brppt1_nand

d63f7130ce board/BuR/common: refactor ft_board_setup(...)

absence of them as error.
Further we've the fact that on different version of the device-tree
files there are different namings of the factory-settings, we consider
this with searching for an alternative name.

changing things as following:

- don't treat as error if the bootloader version cannot written into
devicetree.

- since the naming of the factory-settings are different in different
versions of the provided device-tree we search for the alternate name
"/fset"
