On x86, when both CONFIG_GRUB_CONSOLE and CONFIG_GRUB_SERIAL are set (as
they are by default), the kernel command line will have two console=
entries, such as
console=tty0 console=ttyS0,115200n8
Failsafe was only running a shell on the first defined console, the VGA
console. This is a problem for devices like apu2, where there is only a
serial console and it appears on ttyS0.
Moreover, the console prompt to enter failsafe during boot was delivered
to, and its input read from, the last console= on the kernel command
line. So while the failsafe shell was on the first defined console, only
the last defined console could be used to enter failsafe during boot.
In contrast, the x86 bootloader (GRUB) operates on both the serial
console and the VGA console by virtue of "terminal_{input,output}
console serial". GRUB also provided an alternate means to enter failsafe
from either console. The presence of two console= kernel command line
parameters causes kernel messages to be delivered to both. Under normal
operation (not failsafe), procd runs login in accordance with inittab,
which on x86 specifies ttyS0, hvc0, and tty1, allowing login through any
of serial, hypervisor, or VGA console. Thus, serial access was
consistently available on x86 devices with serial consoles under normal
operation, except for shell access in failsafe mode (without editing the
kernel command line).
By presenting the failsafe prompt, reading failsafe prompt input, and
running failsafe shells on all consoles listed in /proc/cmdline,
failsafe mode will work correctly on devices with a serial console (like
apu2), and the same image without any need for reconfiguration can be
shared by devices with the more traditional (for x86) VGA console. This
improvement should benefit any system with multiple console= arguments,
including x86 and bcm27xx (Raspberry Pi).

Commit ecbcc0b595 bricks devices on which the raw kernel and UBI mtd
partitions overlap.
This is the case of the ZyXEL NR7101 for example. Its OEM bootloader has
no UBI support. OpenWrt splits the stock kernel mtd partition into a raw
kernel part used by the bootloader and a UBI part used to store rootfs
and rootfs_data. Running mtd erase on the complete partition during
sysupgrade erases the UBI part and results in a soft brick.
Arguably the best solution would be to fix the partition layouts so that
kernel and UBI partitions do not overlap, also including a stock_kernel
partition to help reverting to stock firmware. This would have the added
benefit of protecting UBI from kernel images that are excessively large.

See firmware-utils.git commits [1], which implemented the cros-vbutil
verified-boot payload-packing tool, and extended ptgen for the CrOS
kernel partition type. With these, it's now possible to package kernel +
rootfs to make disk images that can boot a Chrome OS-based system (e.g.,
Chromebooks, or even a few AP models).
Regarding PARTUUID= changes: Chromium bootloaders work well with a
partition number offset (i.e., relative to the kernel partition), so
we'll be using a slightly different root UUID line.
NB: I've made this support specific to ip40xx for now, because I only
plan to support an IPQ4019-based AP that uses a Chromium-based
bootloader, but this image format can be used for essentially any
Chromebook, as well as the Google OnHub, a prior Chromium-based AP using
an IPQ8064 chipset.

OpenWrt uses a lot of (b)ash scripts for initial setup. This isn't the
best solution as they almost never consider syncing files / data. Still
this is what we have and we need to try living with it.
Without proper syncing OpenWrt can easily get into an inconsistent state
on power cut. It's because:
1. Actual (flash) inode and data writes are not synchronized
2. Data writeback can take up to 30 seconds (dirty_expire_centisecs)
3. ubifs adds extra 5 seconds (dirty_writeback_centisecs) "delay"
Some possible cases (examples) for new files:
1. Power cut during 5 seconds after write() can result in all data loss
2. Power cut happening between 5 and 35 seconds after write() can result
in empty file (inode flushed after 5 seconds, data flush queued)
Above affects e.g. uci-defaults. After executing some migration script
it may get deleted (whited out) without generated data getting actually
written. Power cut will result in missing data and deleted file.
There are three ways of dealing with that:
1. Rewriting all user-space init to proper C with syncs
2. Trying bash hacks (like creating tmp files & moving them)
3. Adding sync and hoping for no power cut during critical section
This change introduces the last solution that is the simplest. It
reduces time during which things may go wrong from ~35 seconds to
probably less than a second. Of course it applies only to IO operations
performed before /etc/init.d/boot . It's probably the stage when the
most new files get created.
All later changes are usually done using smarter C apps (e.g. busybox or
uci) that creates tmp files and uses rename() that is expected to be
atomic.

Not all targets create /var/lock or touch /var/lock/fw_printenv.lock in
their platform.sh. This is problematic as fw_printenv then fails in
case /var/lock/fw_printenv.lock has not been created by previous calls
to fw_printenv/fw_setenv before sysupgrade is run.
Targets using fw_printenv/fw_setenv during sysupgrade:
* ath79/*
* ipq40xx/*
* ipq806x/*
* kirkwood/*
* layerscape/*
* mediatek/mt7622
* mvebu/*
* ramips/*
* realtek/*
Targets currently using additional steps in /lib/upgrade/platform.sh
to make sure /var/lock/fw_printenv.lock (or at least /var/lock)
actually exists:
* ath79/* (openmesh devices)
* ipq40xx/* (linksys devices)
* ipq806x/* (linksys devices)
* kirkwood/* (linksys devices)
* layerscape/*
* mvebu/cortexa9 (linksys devices)
Given that accessing the U-Boot environment during sysupgrade is not
uncommon and the situation across targets is currently quite diverse,
just make sure both tools as well fw_env.config are always copied to
the ramdisk used for sysupgrade. Also make sure /var/lock always
exists.
This now allows to remove copying of fw_printenv/fw_setenv as well as
fw_env.config, creation of /var/lock or even /var/lock/fw_printenv.lock
from lib/upgrade/platform.sh or files included there.
As the same applies also to 'fwtool' which is used by generic eMMC
sysupgrade, also always copy that to ramdisk.

For sysupgrade on NAND/UBI devices there is the U-Boot environment
variable rootfs_data_max which can be used to limit the size of the
rootfs_data volume created on sysupgrade.
This stopped working reliable with recent kernels, probably due to a
race condition when reading the number of free erase blocks from sysfs
just after removing a volume.
Change the script to just try creating rootfs_data with the desired
size and retry with maximum size in case that fails. Hence calculating
the available size in the script can be dropped which works around the
problem.

Adds generic support for sysupgrading on eMMC-based devices.
Provide function emmc_do_upgrade and emmc_copy_config to be used in

logic over and over again.
Similar to generic sysupgrade on NAND, use environment variables
CI_KERNPART, CI_ROOTPART and newly introduce CI_DATAPART to indicate
GPT partition names to be used. On devices with more than one MMC
block device, CI_ROOTDEV can be used to specify the MMC device for
partition name lookups.
Also allow to select block devices directly using EMMC_KERN_DEV,
EMMC_ROOT_DEV and EMMC_DATA_DEV, as using GPT partition names is not
always an option (e.g. when forced to use MBR).

Currently nand_upgrade_tar() will pass the kernel length
to nand_upgrade_prepare_ubi() in all cases except for when
the kernel is to be installed in a separate partition as a
binary with the MTD tool.
While this is fine for almost all cases newer MikroTik NAND
devices like hAP ac3 require the kernel to be installed as a
UBIFS packed UBI volume in its own partition.
So, since we have a custom recipe to use ubiformat to flash
the kernel in its partition it makes no sense for sysupgrade
to also install the kernel as a UBI volume in the "ubi"
partition as it only wastes space and will never be used.
So, simply check whether CI_KERNPART is set to "none" and
if so unset the "has_kernel" variable which will in turn
prevent the kernel length from being passed on and then
the kernel UBI volume wont be created for no usefull purpose.
The ath79 MikroTik NAND target has been setting CI_KERNPART
to "none" for a while now altough that was not preventing
the kernel to be installed as UBI volume as well.

While an image layout based on MBR and 'bootfs' partition may be easy
to understand for users who are very used to the IBM PC and always have
the option to access the SD card outside of the device (and hence don't
really depend on other recovery methods or dual-boot), in my opinion
it's a dead end for many desirable features on embedded systems,
especially when managed remotely (and hence without an easy option to
access the SD card using another device in case things go wrong, for
example).
Let me explain:
* using a MSDOS/VFAT filesystem to store kernel(s) is problematic, as a
single corruption of the bootfs can render the system into a state
that it no longer boots at all. This makes dual-boot useless, or at
least very tedious to setup with then 2 independent boot partitions
to avoid the single point of failure on a "hot" block (the FAT index
of the boot partition, written every time a file is changed in
bootfs). And well: most targets even store the bootloader environment
in a file in that very same FAT filesystem, hence it cannot be used
to script a reliable dual-boot method (as loading the environment
itself will already fail if the filesystem is corrupted).
* loading the kernel uImage from bootfs and using rootfs inside an
additional partition means the bootloader can only validate the
kernel -- if rootfs is broken or corrupted, this can lead to a reboot
loop, which is often a quite costly thing to happen in terms of
hardware lifetime.
* imitating MBR-boot behavior with a FAT-formatted bootfs partition
(like IBM PC in the 80s and 90s) is just one of many choices on
embedded targets. There are much better options with modern U-Boot
(which is what we use and build from source for all targets booting
off SD cards), see examples in mediatek/mt7622 and mediatek/mt7623.
Hence rename the 'sdcard' feature to 'legacy-sdcard', and prefix
functions with 'legacy_sdcard_' instead of 'sdcard_'.
