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 Smith1-15/+3
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.

None of these actually produce any warnings. My next patch will. Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
2014-10-22fsp/elog: Create a logging frontendAlistair Popple1-0/+2
In order to support fsp-less machines we need to be able to log errors using a BMC or some other mechanism. Currently the error logging code is tightly coupled to the platform making it difficult to add different platforms. This patch factors out the generic parts of the error logging code in preparation for adding different logging backends. It also adds a generic mechanism for pre-allocating a specific number of objects. Signed-off-by: Alistair Popple <alistair@popple.id.au> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
2014-10-22fsp/elog: Separate the PEL log formatting functionsAlistair Popple1-0/+177
The PEL log format is not specific to the FSP. We plan to use the same format for OpenPOWER systems. This patch refactors the code into a platform agnostic file.
