- CONFIG_ENV_FLAGS_LIST_DEFAULT
- CONFIG_ENV_FLAGS_LIST_STATIC
Enable validation of the values given to enviroment variables when
calling env set. Variables can be restricted to only decimal,
hexadecimal, or boolean. If CONFIG_CMD_NET is also defined,
the variables can also be restricted to IP address or MAC address.
The format of the list is:
type_attribute = [s|d|x|b|i|m]
access_atribute = [a|r|o|c]
attributes = type_attribute[access_atribute]
entry = variable_name[:attributes]
list = entry[,list]
The type attributes are:
s - String (default)
d - Decimal
x - Hexadecimal
b - Boolean ([1yYtT|0nNfF])
i - IP address
m - MAC address
The access attributes are:
a - Any (default)
r - Read-only
o - Write-once
c - Change-default
- CONFIG_ENV_FLAGS_LIST_DEFAULT
Define this to a list (string) to define the ".flags"
envirnoment variable in the default or embedded environment.
- CONFIG_ENV_FLAGS_LIST_STATIC
Define this to a list (string) to define validation that
should be done if an entry is not found in the ".flags"
environment variable. To override a setting in the static
list, simply add an entry for the same variable name to the
".flags" variable.
- CONFIG_ENV_ACCESS_IGNORE_FORCE
If defined, don't allow the -f switch to env set override variable
access flags.

of environment data (variable area); in general, we support the

only effect after the next boot (yes, that's just like Windoze :-).
Callback functions for environment variables:
---------------------------------------------
For some environment variables, the behavior of u-boot needs to change
when their values are changed. This functionailty allows functions to
be associated with arbitrary variables. On creation, overwrite, or
deletion, the callback will provide the opportunity for some side
effect to happen or for the change to be rejected.
The callbacks are named and associated with a function using the
U_BOOT_ENV_CALLBACK macro in your board or driver code.
These callbacks are associated with variables in one of two ways. The
static list can be added to by defining CONFIG_ENV_CALLBACK_LIST_STATIC
in the board configuration to a string that defines a list of
associations. The list must be in the following format:
entry = variable_name[:callback_name]
list = entry[,list]
If the callback name is not specified, then the callback is deleted.
Spaces are also allowed anywhere in the list.
Callbacks can also be associated by defining the ".callbacks" variable
with the same list format above. Any association in ".callbacks" will
override any association in the static list. You can define
CONFIG_ENV_CALLBACK_LIST_DEFAULT to a list (string) to define the
".callbacks" envirnoment variable in the default or embedded environment.

- UUID -(Universally Unique Identifier)
- GUID - (Globally Unique ID)
- EFI - (Extensible Firmware Interface)
- UEFI - (Unified EFI) - EFI evolution
- GPT (GUID Partition Table) - it is the EFI standard part
- partitions - lists of available partitions (defined at u-boot):
./include/configs/{target}.h
Introduction:
=============
This document describes the GPT partition table format and usage of
the gpt command in u-boot.
UUID introduction:
====================
GPT for marking disks/partitions is using the UUID. It is supposed to be a
globally unique value. A UUID is a 16-byte (128-bit) number. The number of
theoretically possible UUIDs is therefore about 3 x 10^38.
More often UUID is displayed as 32 hexadecimal digits, in 5 groups,
separated by hyphens, in the form 8-4-4-4-12 for a total of 36 characters
(32 digits and 4 hyphens)
For instance, GUID of Linux data partition: EBD0A0A2-B9E5-4433-87C0-68B6B72699C7
Historically there are 5 methods to generate this number. The oldest one is
combining machine's MAC address and timer (epoch) value.
Successive versions are using MD5 hash, random numbers and SHA-1 hash. All major
OSes and programming languages are providing libraries to compute UUID (e.g.
uuid command line tool).
GPT brief explanation:
======================
Layout:
-------
--------------------------------------------------
LBA 0 |Protective MBR |
----------------------------------------------------------
LBA 1 |Primary GPT Header | Primary
-------------------------------------------------- GPT
LBA 2 |Entry 1|Entry 2| Entry 3| Entry 4|
--------------------------------------------------
LBA 3 |Entries 5 - 128 |
| |
| |
----------------------------------------------------------
LBA 34 |Partition 1 |
| |
-----------------------------------
|Partition 2 |
| |
-----------------------------------
|Partition n |
| |
----------------------------------------------------------
LBA -34 |Entry 1|Entry 2| Entry 3| Entry 4| Secondary
-------------------------------------------------- (bkp)
LBA -33 |Entries 5 - 128 | GPT
| |
| |
LBA -2 | |
--------------------------------------------------
LBA -1 |Secondary GPT Header |
----------------------------------------------------------
For a legacy reasons, GPT's LBA 0 sector has a MBR structure. It is called
"protective MBR".
Its first partition entry ID has 0xEE value, and disk software, which is not
handling the GPT sees it as a storage device without free space.
It is possible to define 128 linearly placed partition entries.
"LBA -1" means the last addressable block (in the mmc subsystem:
"dev_desc->lba - 1")
Primary/Secondary GPT header:
----------------------------
Offset Size Description
0 8 B Signature ("EFI PART", 45 46 49 20 50 41 52 54)
8 4 B Revision (For version 1.0, the value is 00 00 01 00)
12 4 B Header size (in bytes, usually 5C 00 00 00 meaning 92 bytes)
16 4 B CRC32 of header (0 to header size), with this field zeroed
during calculation
20 4 B Reserved (ZERO);
24 8 B Current LBA (location of this header copy)
32 8 B Backup LBA (location of the other header copy)
40 8 B First usable LBA for partitions (primary partition table last
LBA + 1)
48 8 B Last usable LBA (secondary partition table first LBA - 1)
56 16 B Disk GUID (also referred as UUID on UNIXes)
72 8 B Partition entries starting LBA (always 2 in primary copy)
80 4 B Number of partition entries
84 4 B Size of a partition entry (usually 128)
88 4 B CRC32 of partition array
92 * Reserved; must be ZERO (420 bytes for a 512-byte LBA)
TOTAL: 512 B
IMPORTANT:
GPT headers and partition entries are protected by CRC32 (the POSIX CRC32).
Primary GPT header and Secondary GPT header have swapped values of "Current LBA"
and "Backup LBA" and therefore different CRC32 check-sum.
CRC32 for GPT headers (field "CRC of header") are calculated up till
"Header size" (92), NOT 512 bytes.
CRC32 for partition entries (field "CRC32 of partition array") is calculated for
the whole array entry ( Number_of_partition_entries *
sizeof(partition_entry_size (usually 128)))
Observe, how Secondary GPT is placed in the memory. It is NOT a mirror reflect
of the Primary.
Partition Entry Format:
----------------------
Offset Size Description
0 16 B Partition type GUID
16 16 B Unique partition GUID
32 8 B First LBA (Little Endian)
40 8 B Last LBA (inclusive)
48 8 B Attribute flags [+]
56 72 B Partition name (text)
Attribute flags:
Bit 0 - System partition
Bit 60 - Read-only
Bit 62 - Hidden
Bit 63 - Not mount
Creating GPT partitions in U-Boot:
==============
To restore GUID partition table one needs to:
1. Define partition layout in the environment.
Format of partitions layout:
"partitions=uuid_disk=...;name=u-boot,size=60MiB,uuid=...;
name=kernel,size=60MiB,uuid=...;"
or
"partitions=uuid_disk=${uuid_gpt_disk};name=${uboot_name},
size=${uboot_size},uuid=${uboot_uuid};"
Fields 'name', 'size' and 'uuid' are mandatory for every partition.
The field 'start' is optional.
2. Define 'CONFIG_EFI_PARTITION' and 'CONFIG_CMD_GPT'
2. From u-boot prompt type:
gpt write mmc 0 $partitions
Useful info:
============
Two programs, namely: 'fdisk' and 'parted' are recommended to work with GPT
recovery. Parted is able to handle GUID partitions. Unfortunately the 'fdisk'
hasn't got such ability.
Please, pay attention at -l switch for parted.
"uuid" program is recommended to generate UUID string. Moreover it can decode
(-d switch) passed in UUID string. It can be used to generate partitions UUID
passed to u-boot environment variables.

The config option CONFIG_SILENT_CONSOLE can be used to quiet messages
on the console. If the option has been enabled, the output can be
silenced by setting the environment variable "silent". The variable
is latched into the global data at an early stage in the boot process
so deleting it with "setenv" will not take effect until the system is
restarted.

- CONFIG_SILENT_CONSOLE_UPDATE_ON_SET
When the "silent" variable is changed with env set, the change
will take effect immediately.
- CONFIG_SILENT_CONSOLE_UPDATE_ON_RELOC
Some environments are not available until relocation (e.g. NAND)
so this will make the value in the flash env take effect at
relocation.
The following actions are taken if "silent" is set at boot time:
