meta-phosphor/obmc-init.sh: fix panic when rwfs is full

mkdir -p $work will fail if rwfs partition is full, and then it will
cause overlayfs mount fail as well. Finally it cause kernel panic and
bmc fails to boot:

Fix this by not removing workdir directly, but keeping the directory
and removing all entires under it. We will still get below warning,
but it can boot to shell and provide ssh access to give a chance of
recovery.

[    9.519053] overlayfs: failed to create directory run/initramfs/rw/work/work (errno: 28); mounting read-only

Also update related patch file in meta-google to avoid build failure.

OpenBMC

Build Status

OpenBMC is a Linux distribution for management controllers used in devices such as servers, top of rack switches or RAID appliances. It uses Yocto, OpenEmbedded, systemd, and D-Bus to allow easy customization for your platform.

Setting up your OpenBMC project

1) Prerequisite

See the Yocto documentation for the latest requirements

Ubuntu

$ sudo apt install git python3-distutils gcc g++ make file wget \
    gawk diffstat bzip2 cpio chrpath zstd lz4 bzip2

Fedora

$ sudo dnf install git python3 gcc g++ gawk which bzip2 chrpath cpio
hostname file diffutils diffstat lz4 wget zstd rpcgen patch

2) Download the source

git clone https://github.com/openbmc/openbmc
cd openbmc

3) Target your hardware

Any build requires an environment set up according to your hardware target. There is a special script in the root of this repository that can be used to configure the environment as needed. The script is called setup and takes the name of your hardware target as an argument.

The script needs to be sourced while in the top directory of the OpenBMC repository clone, and, if run without arguments, will display the list of supported hardware targets, see the following example:

$ . setup <machine> [build_dir]
Target machine must be specified. Use one of:

bletchley               mihawk                  swift
dl360poc                mori                    tatlin-archive-x86
e3c246d4i               mtjade                  tiogapass
ethanolx                nicole                  transformers
evb-ast2500             olympus-nuvoton         vegman-n110

kudo                    s7106
lannister               s8036

Once you know the target (e.g. romulus), source the setup script as follows:

. setup romulus

4) Build

bitbake obmc-phosphor-image

Additional details can be found in the docs repository.

OpenBMC Development

The OpenBMC community maintains a set of tutorials new users can go through to get up to speed on OpenBMC development out here

Build Validation and Testing

Commits submitted by members of the OpenBMC GitHub community are compiled and tested via our Jenkins server. Commits are run through two levels of testing. At the repository level the makefile make check directive is run. At the system level, the commit is built into a firmware image and run with an arm-softmmu QEMU model against a barrage of CI tests.

Commits submitted by non-members do not automatically proceed through CI testing. After visual inspection of the commit, a CI run can be manually performed by the reviewer.

Automated testing against the QEMU model along with supported systems are performed. The OpenBMC project uses the Robot Framework for all automation. Our complete test repository can be found here.

Submitting Patches

Support of additional hardware and software packages is always welcome. Please follow the contributing guidelines when making a submission. It is expected that contributions contain test cases.

Bug Reporting

Issues are managed on GitHub. It is recommended you search through the issues before opening a new one.

Questions

First, please do a search on the internet. There's a good chance your question has already been asked.

For general questions, please use the openbmc tag on Stack Overflow. Please review the discussion on Stack Overflow licensing before posting any code.

For technical discussions, please see contact info below for Discord and mailing list information. Please don't file an issue to ask a question. You'll get faster results by using the mailing list or Discord.
