2020-03-12Re-license IBM written files as Apache 2.0 OR GPLv2+Stewart Smith8-8/+8
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>

2019-06-04Remove POWER7 and POWER7+ supportStewart Smith2-12/+1
It's been a good long while since either OPAL POWER7 user touched a machine, and even longer since they'd have been okay using an old version rather than tracking master. There's also been no testing of OPAL on POWER7 systems for an awfully long time, so it's pretty safe to assume that it's very much bitrotted. It also saves a whole 14kb of xz compressed payload space.

2018-06-18external/xscom-utils: Add python library for xscom accessMadhavan Srinivasan1-0/+312
Patch adds a simple python library module for xscom access. It directly manipulate the '/access' file for scom read and write from debugfs 'scom' directory. Example on how to generate a getscom using this module: #!/usr/bin/python from adu_scoms import * getscom = GetSCom() getscom.parse_args() getscom.run_command() Sample output for above getscom.py: # ./getscom.py -l Chip ID | Rev | Chip type ---------|-------|----------- 00000008 | DD2.0 | P9 (Nimbus) processor 00000000 | DD2.0 | P9 (Nimbus) processor Signed-off-by: Madhavan Srinivasan <maddy@linux.vnet.ibm.com> Signed-off-by: Stewart Smith <stewart@linux.ibm.com>

2017-08-21external/xscom-utils: Add --list-bitsOliver O'Halloran4-9/+50
When using getscom/putscom it's helpful to know what bits are set in the register. This patch adds an option to print out which bits are set along with the value that was read/written to the register. Note that this output indicates which bits are set using the IBM bit ordering since that's what the XSCOM documentation uses.

2017-03-24external: Update xscom utils for type 1 indirect accessesMichael Neuling3-6/+27
Update get/putscom utils to support type 1 indirect access. Currently we do some (ugly) bit mangling so that we can fit a 64 bit scom address into the debugfs interface. The current code only shifts down the top bit (indirect bit). This patch changes it to shift down the whole top nibble so that the form of the indirection is also shifted. Also currently putscom always reads back the value. This causes a problem for form 1 which can only be written. This patch marks the form 1 as not readable and hence doesn't attempt the read back. The kernel debugfs scom driver doesn't do the bit mangling correctly. So for form1 to work correctly, the kernel debugfs scom driver needs updating. Existing scoms are forwards and backwards compatible with the kernel. (FWIW the kernel PRD scom interface doesn't need to be updated as it passes the whole 64 bit scom address without any bit mangling) Signed-off-by: Michael Neuling <mikey@neuling.org> Reviewed-by: Cédric Le Goater <clg@kaod.org> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
