2023-10-11hdata: split idata accessor functionNicholas Piggin1-7/+17
Add HDIF_idata that returns the idata pointer structure, not a pointer to the data itself. Signed-off-by: Nicholas Piggin <npiggin@gmail.com> Signed-off-by: Reza Arbab <arbab@linux.ibm.com>
2023-10-11hdata: Make hdata child accessors check the headerNicholas Piggin1-0/+12
Like other (idata) accessors already do, check the common header in hdata child accessor calls. Signed-off-by: Nicholas Piggin <npiggin@gmail.com> Signed-off-by: Reza Arbab <arbab@linux.ibm.com>
2023-10-11hdata: Use common code for HDIF header checkNicholas Piggin1-1/+1
Make the HDIF header check use a common function. Signed-off-by: Nicholas Piggin <npiggin@gmail.com> Signed-off-by: Reza Arbab <arbab@linux.ibm.com>
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/+2
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.

2017-09-15hdata: Add an idata array iteratorOliver O'Halloran1-0/+69
Adds HDIF_get_iarray() which retrieves and validates an internal array header and HDIF_iarray_for_each() for walking the individual array entries. This reduces the amount of get-then-check boilerplate that we have with the existing HDIF_get_iarray_item() method for iterating internal data arrays.

2017-06-06hdata: Make out-of-range idata print at PR_DEBUGOliver O'Halloran1-2/+2
Some fields just aren't populated on some systems. Signed-off-by: Oliver O'Halloran <oohall@gmail.com> Reviewed-by: Gavin Shan <gwshan@linux.vnet.ibm.com> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
2017-03-30hdata: print backtraces on HDAT errorsOliver O'Halloran1-0/+9
Currently these aren't sufficently obnoxious, so make them more so. HDAT parse errors usually mean we won't be able to generate enough of a device-tree to boot so we want to make this much more obvious.

2017-01-10hdat: make HDIF_child() print more useful errorsOliver O'Halloran1-2/+2
The HDAT has very fixed relationships between a parent and child structures. When parsing the HDAT we always know what type of child that we expect and we will error out if there is a mismatch between what we get and what expect. This patch just prints out what we got in addition to what we expected to help with debugging.
