Christopher Hill b7a8a54542 ath79: add support for MikroTik RouterBOARD 493G (rb4xx series)
This patch adds support for the MikroTik RouterBOARD RB493G, ported
from the ar71xx target.

See for details

- SoC Qualcomm Atheros AR7161
- RAM: 256 MiB
- Storage: 128MiB NAND
- Ethernet: 9x 1000/100/10 Mbps
- USB 1x 2.0 / 1.0 type A
- PCIe: 3x Mini slot
- MicroSD slot

- Board/system detection
- Ethernet
- LEDs
- Sysupgrade

Enabled (but untested due to lack of hardware):
- PCIe - ath79_pci_irq struct has the slot/pin/IRQ mappings if needed

Installation methods:
- tftp boot initramfs image, scp then flash via "sysupgrade -n"
- nand boot existing OpenWrt, scp then flash via "sysupgrade -n"

- initramfs image will not work if uncompressed image size over ~8.5Mb
- The "rb4xx" drivers have been enabled

李国 a6b7c3e672 x86: generate EFI platform bootable images
Add EFI platform bootable images for x86 platforms. These images can
also boot from legacy BIOS platform.

EFI System Partition need to be fat12/fat16/fat32 (not need to load
filesystem drivers), so the first partition of EFI images are not ext4
filesystem any more.

GPT partition table has an alternate partition table, we did not
generate it. This may cause problems when use these images as qemu disk
(kernel can not find rootfs), we pad enough sectors will be ok.

Paul Spooren cb007a7bf6 x86: switch image generation to new code
This commit introduces few related changes which need to be done in
single commit to keep images buildable between git revisions. In result
it retains all previous image creation possibilities with slight name
change of generated images. Brief summary of the commit:

* Split up image generation recipe to smaller chunks to make it more
  generic and reusable.

* Make iso images x86 specific and drop their definition as root

* Convert image creation process to generic code specified in

* Make geode subtarget inherit features from the main target instead of
  redefining them.

* For subtargets create device definitions with basic packages set.

Adrian Schmutzler 7d7aa2fd92 brcm2708: rename target to bcm27xx
This change makes the names of Broadcom targets consistent by using
the common notation based on SoC/CPU ID (which is used internally
anyway), bcmXXXX instead of brcmXXXX.
This is even used for target TITLE in make menuconfig already,
only the short target name used brcm so far.

Despite, since subtargets range from bcm2708 to bcm2711, it seems
appropriate to use bcm27xx instead of bcm2708 (again, as already done

This also renames the packages brcm2708-userland and brcm2708-gpu-fw.

build: set TARGET_ROOTFS_PARTSIZE to make combined image fit in 128MB
Change TARGET_ROOTFS_PARTSIZE from 128 to 104 MiB, so the whole image
(bootloader + boot + root) will fit on a 128MB CF card by default.

With these settings, the generated images (tested on x86-generic and
x86-64) have 126,353,408 bytes; the smallest CF card marketed as "128MB"
that I found a datasheet for (a Transcend TS128MCF80) has 126,959,616

Petr Štetiar d03ef97c1b build: remove TARGET_IMAGES_PAD option
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

Stijn Segers 5cd49395d3 lantiq/xrx200: enable initramfs 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/ 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.

Prior to commit 1496b95a0 ("x86: clean up default grub baudrate

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.

Felix Fietkau 4cc1f1ac1c x86: revert default root size back to 256 MB
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.

Jo-Philipp Wich dc6cc04016 config: ext4: increase x86 rootfs size to 2GB to support online resize2fs
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
