drm/nouveau: fix bogus GPL-2 license header The bulk SPDX addition made all these files into GPL-2.0 licensed files. However the remainder of the project is MIT-licensed, these files (primarily header files) were simply missing the boiler plate and got caught up in the global update. Fixes: b24413180f5 (License cleanup: add SPDX GPL-2.0 license identifier to files with no license) Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> Acked-by: Emil Velikov <emil.l.velikov@gmail.com> Acked-by: Karol Herbst <kherbst@redhat.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

drm/nouveau/bios: split out shadow methods We're about to need to be able to fetch additional chunks of data beyond the primary bios image, which makes fetching a lot more complicated. This splits out the verious shadowing routines to be nothing more than very dumb "fetch this much data from this offset" routines, and leaves the logic of what and how much to fetch in common code.

drm/nouveau/bios: namespace + nvidia gpu names (no binary change) The namespace of NVKM is being changed to nvkm_ instead of nouveau_, which will be used for the DRM part of the driver. This is being done in order to make it very clear as to what part of the driver a given symbol belongs to, and as a minor step towards splitting the DRM driver out to be able to stand on its own (for virt). Because there's already a large amount of churn here anyway, this is as good a time as any to also switch to NVIDIA's device and chipset naming to ease collaboration with them. A comparison of objdump disassemblies proves no code changes. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

drm/nouveau/bios: fix OF loading Currently OF bios load fails for a few reasons: - checksum failure - bios size too small - no PCIR header - bios length not a multiple of 4 In this change, we resolve all of the above by ignoring any checksum failures (since OF VBIOS tends not to have a checksum), and faking the PCIR data when loading from OF.

drm/nouveau/bios: Rename prom_init() and friends functions While working at fixing powerpc headers, I ended up with the following error. drivers/gpu/drm/nouveau/nvkm/subdev/bios/shadowrom.c:48:1: error: conflicting types for 'prom_init'; have 'void *(struct nvkm_bios *, const char *)' make[5]: *** [scripts/Makefile.build:288: drivers/gpu/drm/nouveau/nvkm/subdev/bios/shadowrom.o] Error 1 powerpc and a few other architectures have a prom_init() global function. One day or another it will conflict with the one in shadowrom.c Those being static, they can easily be renamed. Do it. While at it, also rename the ops structure as 'nvbios_prom' instead of 'nvbios_rom' in order to make it clear that it refers to the NV_PROM device.
