Having access to the secboot instance loading a LS firmware can be useful to LS firmware handlers. At least more useful than just having an out-of-context subdev pointer. GP10B's firmware will also need to know the WPR address, which can be obtained from the secboot instance.

Change the secboot and msgqueue interfaces to take a mask of falcons to reset instead of a single falcon. The GP10B firmware interface requires FECS and GPCCS to be booted in a single firmware command. For firmwares that only support single falcon boot, it is trivial to loop over the mask and boot each falcons individually.

The gk20a implementation of instance memory uses vmap()/vunmap() to map memory regions into the kernel's virtual address space. These functions may sleep, so protecting them by a spin lock is not safe. This triggers a warning if the DEBUG_ATOMIC_SLEEP Kconfig option is enabled. Fix this by using a mutex instead.

When the atomic support was added to nouveau, the DRM core did not do this.

The NV4A (aka NV44A) is an oddity in the family. It only comes in AGP and PCI varieties, rather than a core PCIE chip with a bridge for AGP/PCI as necessary. As a result, it appears that the MMU is also non-functional. For AGP cards, the vast majority of the NV4A lineup, this worked out since we force AGP cards to use the nv04 mmu. However for PCI variants, this did not work. Switching to the NV04 MMU makes it work like a charm. Thanks to mwk for the suggestion. This should be a no-op for NV4A AGP boards, as they were using it already.

Cleanup overly complex omap_modeset_init(). The function is trying to support many unusual configuration, that have never been tested and are not supported by other parts of the dirver. After cleanup the init function creates exactly one connector, encoder, crtc, and primary plane per each connected dss-device. Each connector->encoder->crtc chain is expected to be separate and each crtc is connect to a single dss-channel. If the configuration does not match the expectations or exceeds the available resources, the configuration is rejected.

At the moment VSYNC/HSYNC/DE high/low flags set by the panel/encoder drivers get lost when the videotimings are translated to DRM's videomode, as DRM's mode does not have corresponding flags. DRM has bus-flags for this purpose, and while it lacks a few flags at the moment, it should be used here. However, until we rewrite omapdrm's device model, using bus-flags is rather difficult. As a short term fix, this patch makes sure that every time the videomode is set in omap_crtc_mode_set_nofb(), the driver asks for the SYNC/DE flags from the panel/encoder drivers, and thus we get the correct flags into use.
