bootstd: Use the bootargs env var for changing the cmdline

2023-07-16T15:13:17+00:00

The "bootargs" environment variable is used to set the command-line
arguments to pass to the OS. Use this same mechanism with bootstd as well.
When the variable is updated, it is written to the current bootflow. When
the current bootflow is updated, the environment variable is updated too.

global: Finish CONFIG -> CFG migration

2023-01-20T17:27:24+00:00

At this point, the remaining places where we have a symbol that is
defined as CONFIG_... are in fairly odd locations. While as much dead
code has been removed as possible, some of these locations are simply
less obvious at first. In other cases, this code is used, but was
defined in such a way as to have been missed by earlier checks.  Perform
a rename of all such remaining symbols to be CFG_... rather than
CONFIG_...

net: ipv6: Add callbacks declarations to get access to IPv6 variables

2022-12-05T17:47:16+00:00

Set up callbacks for main IPv6 variables ip6add, serverip6, gatewayip6
and set options to them in flag file. These variables are often set up by
users.

bootstd: Add the bootmeth uclass and helpers

2022-04-25T14:00:04+00:00

A bootmeth is a method of locating an operating system. For now, just
add the uclass itself. Drivers for particular bootmeths are added later.

If no bootmeths devices are included in the devicetree, create them
automatically. This avoids the need for boilerplate in the devicetree
files.

env: remove callback.o for an SPL build

2020-04-24T14:09:59+00:00

env.h says this about about callback declarations (U_BOOT_ENV_CALLBACK):

 * For SPL these are silently dropped to reduce code size, since environment
 * callbacks are not supported with SPL.

So env_callback_init() does a lot of work to not find anything in the
guaranteed empty env_clbk list. Drop callback.o entirely from the link
and stub out the only public function defined in callback.o. This cuts
about 600 bytes from the SPL on my ppc build.

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.

env: Move callback definitions to env.h

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

These definitions are effectively part of the 'public' API of the
environment implementation since they do not require access to any
internal variables. Move them to the env.h header.
