env: Add support for explicit write access list

2020-07-31T14:13:00+00:00

This option marks any U-Boot variable which does not have explicit 'w'
writeable flag set as read-only. This way the environment can be locked
down and only variables explicitly configured to be writeable can ever
be changed by either 'env import', 'env set' or loading user environment
from environment storage.

env: net: U_BOOT_ENV_CALLBACKs should not depend on CMD_NET

2019-09-04T16:37:19+00:00

Some environment variables are relevant for networking. For these
U_BOOT_ENV_CALLBACKs have been defined. When the corresponding environment
variable is updated the callback updates the state of the network
sub-system.

In the UEFI subsystem we can use the network even if CONFIG_CMD_NET is not
defined.

Let the usage of the U_BOOT_ENV_CALLBACKs depend on CONFIG_NET and not on
CONFIG_CMD_NET.

env: Drop the ENTRY typedef

2019-08-11T20:43:41+00:00

U-Boot is not supposed to use typedef for structs anymore. Also this name
is the same as the ENTRY() macro used in assembler files, and 'entry'
itself is widely used in U-Boot (>8k matches).

Drop the typedef and rename the struct to env_entry to reduce confusion.

net: fix env flags for eth10addr and above

2019-01-24T17:35:28+00:00

With CONFIG_REGEX enabled, ETHADDR_WILDCARD is set up for up to 10
interfaces (0..9) as the number can only have one digit.

On boards with more than 10 interfaces, this leads to the protection
and format checks being absent for eth10addr and above.

Fix this by changing ETHADDR_WILDCARD from "\\d?" to "\\d*" to allow
more than one digit.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

common/env_flags.c: Add function to validate a MAC address

2015-09-21T15:29:47+00:00

The code that checks if a string has the format of a MAC address has been
moved to a separate function called eth_validate_ethaddr_str().

This has been done to allow other components (such as vsc9953 driver)
to validate a MAC address.
