90534ea56e configs: openrd: remove non-dm MMC driver
Unfortunately this board has no DM support at all. We are also way past
the deadline for driver model support for various devices on this board.

a751f83bb2 arm: mvebu: ds414: Add sample u-boot update command
Call 'run update_uboot' to fetch u-boot-spl.kwb via TFTP and write it
into the correct SPI flash location. The latter's size is defined in
DS414's DTB file, so hard-coding it should be acceptable here.

Take care to not append garbage from RAM to the written image and to
stay within assigned flash boundaries even if an oversized image was
fetched.

e471ddf0f3 arm: mvebu: board/Synology: Unify legacy kernel support
Move the relevant bits from ds109.{c,h} into common/ and adjust the code
to fit both DS109 and DS414. Moreover:

* Introduce syno_board_id() which translates CONFIG_MACH_TYPE into the
  expected board ID tag value.

* Properly initialize isusbhost, mac and mtu fields from env variables.

* Set the right bootargs/bootcmd to correctly boot legacy kernel out of
  the (DS414) box. Getting the ramdisk location right is a bit tedious.

fc25ffe7d2 JFFS2: fix jffs2 summary datacrc status uninitialized
The function jffs2_1pass_read_inode() was discarding the summary
inodes and dirent because the value in datacrc flag wasn't
initialized in function jffs2_sum_process_sum_data().

This fix initializes the status of all summary records to indicate
that the CRC needs to be verified when they are loaded.

Before this fix, the behaviors produced by the undefined value of
datacrc was:
- Summary's registries were discarded when 'b->datacrc' is equal
  as 'CRC_BAD'.
- Summary's registries were not checked when b->datacrc differs of
  'CRC_BAD' and 'CRC_UNKNOWN'

So, almost all of the time the crc just isn't checked, and in some
cases the registries are discarded.

88965fef6e arm: mvebu: Espressobin: Enable watchdog support but do not start it
Espressobin had disabled watchdog support (CONFIG_WDT) because older stable
Linux kernel versions (which are used by current stable OpenWRT and Debian
versions) do not have support for Armada 3700 watchdog driver. Therefore
they are not able to periodically kick watchdog so Espressobin enter into
boot loop.

This change enable CONFIG_WDT, CONFIG_WDT_ARMADA_37XX and CONFIG_CMD_WDT
options which add support for U-Boot 'wdt' command. And unset new
CONFIG_WATCHDOG_AUTOSTART option which cause that watchdog is not
automatically started by U-Boot during init phase, like when CONFIG_WDT
option is not set at all.

So with this change, U-Boot on Espressobin would have working 'wdt' command
which can be used from boot scripts (e.g. for enabling watchdog prior new
Linux booting kernel). But default behavior of watchdog status stays
unchanged, U-Boot does not start watchdog on Espressobin during its init
phase.

830d29ac37 watchdog: Allow to use CONFIG_WDT without starting watchdog
In some cases it is useful to compile support for U-Boot command 'wdt'
without starting HW watchdog in early U-Boot phase. For example when the
user want to start the watchdog only on demand by some boot script.

This change adds a new compile option WATCHDOG_AUTOSTART to control whether
U-Boot should automatically start the watchdog during init phase or not.

This option is enabled by default as it was the default behavior prior
introducing this new change. When compiling U-Boot users can decide to turn
this option off.
