2020-03-12Re-license IBM written files as Apache 2.0 OR GPLv2+Stewart Smith1-1/+1
SPDX makes it a simpler diff. I have audited the commit history of each file to ensure that they are exclusively authored by IBM and thus we have the right to relicense. The motivation behind this is twofold: 1) We want to enable experiments with coreboot, which is GPLv2 licensed 2) An upcoming firmware component wants to incorporate code from skiboot and code from the Linux kernel, which is GPLv2 licensed. I have gone through the IBM internal way of gaining approval for this. The following files are not exclusively authored by IBM, so are *not* included in this update (I will be seeking approval from contributors): core/direct-controls.c core/flash.c core/pcie-slot.c external/common/arch_flash_unknown.c external/common/rules.mk external/gard/Makefile external/gard/rules.mk external/opal-prd/Makefile external/pflash/Makefile external/xscom-utils/Makefile hdata/vpd.c hw/dts.c hw/ipmi/ipmi-watchdog.c hw/phb4.c include/cpu.h include/phb4.h include/platform.h libflash/libffs.c libstb/mbedtls/sha512.c libstb/mbedtls/sha512.h platforms/astbmc/barreleye.c platforms/astbmc/garrison.c platforms/astbmc/mihawk.c platforms/astbmc/nicole.c platforms/astbmc/p8dnu.c platforms/astbmc/p8dtu.c platforms/astbmc/p9dsu.c platforms/astbmc/vesnin.c platforms/rhesus/ec/config.h platforms/rhesus/ec/gpio.h platforms/rhesus/gpio.c platforms/rhesus/rhesus.c platforms/astbmc/talos.c platforms/astbmc/romulus.c Signed-off-by: Stewart Smith <stewart@linux.ibm.com> [oliver: fixed up the drift] Signed-off-by: Oliver O'Halloran <oohall@gmail.com>
2019-07-26SPDX-ify all skiboot codeStewart Smith1-13/+4
Use Software Package Data Exchange (SPDX) to indicate license for each file that is unique to skiboot. At the same time, ensure the (C) who and years are correct.

2015-03-17external/opal-prd: Unify logging calls and log to syslogJeremy Kerr1-5/+8
This change unifies the printf/fprintf/warn/err/perror calls into: pr_log(level, fmt, ...). While doing this, add prefixes to each message, to signify the functionality that raised the log message. We also add syslog initialisation, so that we can log to the system-wide syslog facility. Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
2015-03-17external/opal-prd: Add a helper for module loadingJeremy Kerr1-0/+55
Rather than calling system("modprobe ...") in different locations, this change introduces an insert_module() helper function. We use this for the existing i2c modprobe, and add one for the ipmi devintf module too. We won't need the i2c-opal module, as it should be automatically loaded by the platform device.
