ARM: Distro boot: document the need for fdtfile variable to be set

2021-01-27T06:25:39+00:00

When testing builds provided in https://github.com/openwrt/openwrt/pull/3360
I discovered that fdtfile was not set and as a result the firmware was not
functional. So I am documenting what is needed.

image: Add compressed Image parsing support in booti.

2020-04-17T16:32:36+00:00

Add compressed Image parsing support so that booti can parse both
flat and compressed Image to boot Linux. Currently, it is difficult
to calculate a safe address for every board where the compressed
image can be decompressed. It is also not possible to figure out the
size of the compressed file as well. Thus, user need to set two
additional environment variables kernel_comp_addr_r and filesize to
make this work.

Following compression methods are supported for now.
lzma, lzo, bzip2, gzip.

lz4 support is not added as ARM64 kernel generates a lz4 compressed
image with legacy header which U-Boot doesn't know how to parse and
decompress.

Tested on HiFive Unleashed and Qemu for RISC-V.
Tested on Qemu for ARM64.

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.

distro: use imply to enable DISTRO_DEFAULTS as SoC default

2018-04-28T14:42:35+00:00

The default of DISTRO_DEFAULTS is messy.  Using the 'imply' keyword
is equivalent and cleaner.

Kconfig: Add a new DISTRO_DEFAULTS Kconfig option

2016-06-21T01:30:13+00:00

DISTRO_DEFAULTS is intended to mirror / replace
include/config_distro_defaults.h.

The intend is for boards which include this file to select this from
their Kconfig files and when moving setting to Kconfig which are #define-ed
in config_distro_defaults.h to select this from DISTRO_DEFAULTS so that
boards which have selected DISTRO_DEFAULTS will keep the same configuration
as before without needing any defconfig file changes.

The initial list of selected things matches all settings recently removed
from config_distro_defaults.h because they have been converted to Kconfig,
with the exception of CMD_ELF and CMD_NET, which have a default of y, if
the default of these ever changes they should be selected by DISTRO_DEFAULTS
too.

For testing and example purposes this commit also converts ARCH_SUNXI
to use DISTRO_DEFAULT instead of selecting everything it needs itself.
