It's being used only in x86 target to produce combined images, where
it's mandatory to have padded images in order to produce working
squashfs combined images usable in QEMU.
Currently we're producing unusable x86 combined squashfs images
(18.06.1, 18.06.2 and snapshots) as we don't enable TARGET_IMAGES_PAD,
thus providing very small space for the overlay filesystem, leading to
the following with OpenWrt 18.06.1 r7258-5eb055306f images on x86 QEMU:
root@(none):/# mount | egrep 'root|overlay'
/dev/root on /rom type squashfs
/dev/loop0 on /overlay type ext4
overlayfs:/overlay on / type overlay
root@(none):/# df -h | egrep 'root|overlay|Size'
Filesystem Size Used Available Use% Mounted on
/dev/root 2.5M 2.5M 0 100% /rom
/dev/loop0 113.0K 8.0K 97.0K 8% /overlay
overlayfs:/overlay 113.0K 8.0K 97.0K 8% /
So we should rather ensure proper image padding in image generation code
and we shouldn't rely on config options in order to generate usable
images.

Commit eae6cac6a3 ("lantiq: add support for AVM FRITZ!Box 7362 SL"), but
one needs an initramfs image to flash OpenWrt from stock firmware (as
described in the commit log). This patch has the initramfs image built
by default.
Thanks to blogic (for pointing to the FEATURES declaration in the target
Makefiles) and Musashino on the forum for suggesting
config/Config-images.in needed editing too. While at it, reorder the
TARGET_INITRAMFS_COMPRESSION_LZMA declarations alphabetically.
This patch will result in initramfs images for all lantiq subtargets
that have the ramdisk flag set. I tested on the falcon and ase
subtargets, which lack that flag, to confirm they don't produce any
initramfs images with this patch - which they do not.
Given the limited scope of the lantiq (sub)target(s), blogic indicated
this should be OK.

This patch adds the boot-part feature which enables the brcm2708
target move from the custom boot partition size config option to
the generic CONFIG_TARGET_KERNEL_PARTSIZE.
Note:
For people using custom images: Just like with
CONFIG_TARGET_ROOTFS_PARTSIZE changing the value
can cause sysupgrade to repartition the device!
Make sure to have a backup in this case.

The sdcard image generation uses CONFIG_TARGET_ROOTFS_PARTSIZE, which is
currently bound to TARGET_ROOTFS_EXT4FS on this target.
Since the rootfs is squashfs anyway, allow deselecting of the ext4fs
one.

Symbol CONFIG_INITRAMFS_FORCE allows to ignore the value passed by the
bootloader.
By default, all symbols containing INITRAMFS are wiped from the final
config and then re-added conditionally.
Add support for this symbol, as the build will stop otherwise

Prior to commit 1496b95a0 ("x86: clean up default grub baudrate
settings") we had three different baud rates for the Geode targets:
19200 for net5501, 38400 for alix2, and 115200 for Geos.
It doesn't seem that there's a very good reason for varying from our
default 115200 baud, so let's make the Geode target do that instead.

2 GB is overkill and was only added to allow unlimited ext4 resizing,
which is a pretty rare use case. 256 MB allows resizing up to 256 GB,
which should be good enough for almost all users.
A lot of this is mostly irrelevant anyway, since you can just use
squashfs + ext4 overlay.
Signed-off-by: Felix Fietkau <nbd@nbd.name>
The current default rootfs size of 256MB in conjunction with 4K blocks
produces an ext4 filesystem which lacks the appropriate amount of backup GDT
entries to support online-resizing.
For x86 targets, increase the default rootfs size to 2048MB which allows
online resizing the filesystem to up to 2TB which is the current theoretical
maximum for LEDE, due to missing GPT support on the root block device.
Note that the filesystem artefact will not occupy 2GB on the build system as
the make_ext4fs utility uses sparse files to generate the filesystem images,
so the actual disk usage is much lower. Furthermore the filesystem images
are gzip compressed, shrinking them to only a few megabytes on the download
server.

Added gen_mvebu_sdcard_img.sh to facilitate creating an fixed-size sdcard image,
adding the bootloader and populating it with actual data.
Added the required rules for creating a 4GB sdcard image according to this layout:
p0: boot (fat32)
p1: rootfs (squashfs)
p2: rootfs_data (ext4)
This should be generic to any mvebu boards that can boot from block storage.
Added the new sdcard image to the Clearfog image profile.

The MR24's u-boot takes it sweet time decompressing the
LZMA-packed initramfs image. A user reported that
compared to the old gzip method in v2: it "takes a ton
longer to decompress like 4\x the old boot time for
decompression".
This patch also fixes a issue with the WNDR4700's initramfs
image getting to big and causing the following u-boot crash
during the decompression:
"Uncompressing Multi-File Image ... Error: inflate() returned -5
out-of-mem or overwrite error - must RESET board to recover"
This patch fixes both issues by reverting the MR24's initramfs
compression method back to gzip. And choosing to compress the
initramfs within the initramfs image as LZMA by default.
