5 menuconfig BOOTCOUNT_LIMIT
6 bool "Enable support for checking boot count limit"
8 Enable checking for exceeding the boot count limit.
9 More information: http://www.denx.de/wiki/DULG/UBootBootCountLimit
14 prompt "Boot count device"
15 default BOOTCOUNT_AM33XX if AM33XX || SOC_DA8XX
18 bool "Boot counter on EXT filesystem"
20 Add support for maintaining boot count in a file on an EXT
23 config BOOTCOUNT_AM33XX
24 bool "Boot counter in AM33XX RTC IP block"
25 depends on AM33XX || SOC_DA8XX
27 A bootcount driver for the RTC IP block found on many TI platforms.
28 This requires the RTC clocks, etc, to be enabled prior to use and
29 not all boards with this IP block on it will have the RTC in use.
32 bool "Boot counter in environment"
34 If no softreset save registers are found on the hardware
35 "bootcount" is stored in the environment. To prevent a
36 saveenv on all reboots, the environment variable
37 "upgrade_available" is used. If "upgrade_available" is
38 0, "bootcount" is always 0, if "upgrade_available" is
39 1 "bootcount" is incremented in the environment.
40 So the Userspace Application must set the "upgrade_available"
41 and "bootcount" variable to 0, if a boot was successfully.
44 bool "Boot counter in RAM"
46 Store the bootcount in DRAM protected against against bit errors
47 due to short power loss or holding a system in RESET.
51 config SYS_BOOTCOUNT_SINGLEWORD
52 bool "Use single word to pack boot count and magic value"
54 This option enables packing boot count magic value and boot count
55 into single word (32 bits).
57 config SYS_BOOTCOUNT_EXT_INTERFACE
58 string "Interface on which to find boot counter EXT filesystem"
60 depends on BOOTCOUNT_EXT
62 Set the interface to use when locating the filesystem to use for the
65 config SYS_BOOTCOUNT_EXT_DEVPART
66 string "Partition of the boot counter EXT filesystem"
68 depends on BOOTCOUNT_EXT
70 Set the partition to use when locating the filesystem to use for the
73 config SYS_BOOTCOUNT_EXT_NAME
74 string "Path and filename of the EXT filesystem based boot counter"
75 default "/boot/failures"
76 depends on BOOTCOUNT_EXT
78 Set the filename and path of the file used to store the boot counter.
80 config SYS_BOOTCOUNT_ADDR
81 hex "RAM address used for reading and writing the boot counter"
83 depends on BOOTCOUNT_EXT
85 Set the address used for reading and writing the boot counter.
