The patch to relax flag requirements was not accepted[1], so we still have
to have separate bootcommands depending on CMD_BOOTFLOW_FULL.

The previous attempt at this did not work, since it used the wrong name
for the options.

Fix this and change the message to mention BOOTSTD_FULL since this affects
not just the flags, but all functionality, so is more likely what the user
wants.

Drop the useless condition on CMD_BOOTFLOW_FULL while we are here.

Fixes: a91492b6e9c ("bootstd: Provide a default command")

We have several Kconfig options for ACPI, but all relate to specific
functions, such as generating tables and AML code.

Add a new option which controls including basic ACPI library code,
including the lib/acpi directory. This will allow us to add functions
which are available even if table generation is not supported.

Adjust the command to avoid a build error when ACPIGEN is not enabled.

In IPv6, the default gateway and prefix length are determined by receiving
a router advertisement as defined in -
https://www.rfc-editor.org/rfc/rfc4861.

Add support for sending router solicitation (RS) and processing router
advertisements (RA).

If the RA has prefix info option and following conditions are met, then
gatewayip6 and net_prefix_length of ip6addr env variables are initialized.
These are later consumed by IPv6 code for non-local destination IP.

- "Router Lifetime" != 0
- Prefix is NOT link-local prefix (0xfe80::/10)
- L flag is 1
- "Valid Lifetime" != 0

Timing Parameters:
- MAX_RTR_SOLICITATION_DELAY (0-1s)
- RTR_SOLICITATION_INTERVAL (4s) (min retransmit delay)
- MAX_RTR_SOLICITATIONS (3 RS transmissions)

The functionality is enabled by CONFIG_IPV6_ROUTER_DISCOVERY and invoked
automatically from net_init_loop().

Add a frontend for the blkmap subsystem. In addition to the common
block device operations, this allows users to create and destroy
devices, and map in memory and slices of other block devices.

With that we support two primary use-cases:

- Being able to "distro boot" from a RAM disk. I.e., from an image
  where the kernel is stored in /boot of some filesystem supported
  by U-Boot.

- Accessing filesystems not located on exact partition boundaries,
  e.g. when a filesystem image is wrapped in an FIT image and stored
  in a disk partition.

Enable tuning of the PCI Express MPS (Maximum Payload Size) of
each device. The Maximum Read Request Size is not altered.

The SAFE method uses the largest MPS value supported by all devices in the
system for each device. This method is the same algorithm as used by Linux
pci=pcie_bus_safe.

The PEER2PEER method sets all devices to the minimal (128 byte) MPS, which
allows hot plug of devices later that might only support the minimum size,
and ensures compatibility of DMA between two devices on the bus.
