-Boot Count Limit
-================
-
-This is enabled by CONFIG_BOOTCOUNT_LIMIT.
-
-This allows to detect multiple failed attempts to boot Linux.
-
-After a power-on reset, the "bootcount" variable will be initialized to 1, and
-each reboot will increment the value by 1.
-
-If, after a reboot, the new value of "bootcount" exceeds the value of
-"bootlimit", then instead of the standard boot action (executing the contents of
-"bootcmd"), an alternate boot action will be performed, and the contents of
-"altbootcmd" will be executed.
-
-If the variable "bootlimit" is not defined in the environment, the Boot Count
-Limit feature is disabled. If it is enabled, but "altbootcmd" is not defined,
-then U-Boot will drop into interactive mode and remain there.
-
-It is the responsibility of some application code (typically a Linux
-application) to reset the variable "bootcount" to 0 when the system booted
-successfully, thus allowing for more boot cycles.
-
-CONFIG_BOOTCOUNT_FS
---------------------
-
-This adds support for maintaining boot count in a file on a filesystem.
-Supported filesystems are FAT and EXT. The file to use is defined by:
-
-CONFIG_SYS_BOOTCOUNT_FS_INTERFACE
-CONFIG_SYS_BOOTCOUNT_FS_DEVPART
-CONFIG_SYS_BOOTCOUNT_FS_NAME
-
-The format of the file is:
-
-==== =================
-type entry
-==== =================
-u8   magic
-u8   version
-u8   bootcount
-u8   upgrade_available
-==== =================
-
-To prevent unattended usage of "altbootcmd", the "upgrade_available" variable is
-used.
-If "upgrade_available" is 0, "bootcount" is not saved.
-If "upgrade_available" is 1, "bootcount" is saved.
-So a userspace application should take care of setting the "upgrade_available"
-and "bootcount" variables to 0, if the system boots successfully.
-This also avoids writing the "bootcount" information on all reboots.

+Boot Count Limit
+================
+
+This is enabled by CONFIG_BOOTCOUNT_LIMIT.
+
+This allows to detect multiple failed attempts to boot Linux.
+
+After a power-on reset, the ``bootcount`` variable will be initialized to 1, and
+each reboot will increment the value by 1.
+
+If, after a reboot, the new value of ``bootcount`` exceeds the value of
+``bootlimit``, then instead of the standard boot action (executing the contents
+of ``bootcmd``), an alternate boot action will be performed, and the contents of
+``altbootcmd`` will be executed.
+
+If the variable ``bootlimit`` is not defined in the environment, the Boot Count
+Limit feature is disabled. If it is enabled, but ``altbootcmd`` is not defined,
