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>
2019-12-16opal-api: add endian conversions to most opal callsNicholas Piggin1-4/+10
This adds missing endian conversions to most calls, sufficient at least to handle calls from a kernel booting on mambo. Subsystems requiring more extensive changes (e.g., xive) will be done with individual changes.

2019-07-26SPDX-ify all skiboot codeStewart Smith1-12/+5
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.

2017-07-28psr: occ: Add support to change power-shifting-ratioShilpasri G Bhat1-0/+42
Add support to set the CPU-GPU power shifting ratio which is used by the OCC power capping algorithm. PSR value of 100 takes all power away from CPU first and a PSR value of 0 caps GPU first.
