/*
* Secure boot is the process by which NVIDIA-signed firmware is loaded into
* some of the falcons of a GPU. For production devices this is the only way
* for the firmware to access useful (but sensitive) registers.
*
* A Falcon microprocessor supporting advanced security modes can run in one of
* three modes:
*
* - Non-secure (NS). In this mode, functionality is similar to Falcon
* architectures before security modes were introduced (pre-Maxwell), but
* capability is restricted. In particular, certain registers may be
* inaccessible for reads and/or writes, and physical memory access may be
* disabled (on certain Falcon instances). This is the only possible mode that
* can be used if you don't have microcode cryptographically signed by NVIDIA.
*
* - Heavy Secure (HS). In this mode, the microprocessor is a black box - it's
* not possible to read or write any Falcon internal state or Falcon registers
* from outside the Falcon (for example, from the host system). The only way
* to enable this mode is by loading microcode that has been signed by NVIDIA.
* (The loading process involves tagging the IMEM block as secure, writing the
* signature into a Falcon register, and starting execution. The hardware will
* validate the signature, and if valid, grant HS privileges.)
*
* - Light Secure (LS). In this mode, the microprocessor has more privileges
* than NS but fewer than HS. Some of the microprocessor state is visible to
* host software to ease debugging. The only way to enable this mode is by HS
* microcode enabling LS mode. Some privileges available to HS mode are not
* available here. LS mode is introduced in GM20x.
*
* Secure boot consists in temporarily switching a HS-capable falcon (typically
* PMU) into HS mode in order to validate the LS firmwares of managed falcons,
* load them, and switch managed falcons into LS mode. Once secure boot
* completes, no falcon remains in HS mode.
*
* Secure boot requires a write-protected memory region (WPR) which can only be
* written by the secure falcon. On dGPU, the driver sets up the WPR region in
* video memory. On Tegra, it is set up by the bootloader and its location and
* size written into memory controller registers.
*
* The secure boot process takes place as follows:
*
* 1) A LS blob is constructed that contains all the LS firmwares we want to
* load, along with their signatures and bootloaders.
*
* 2) A HS blob (also called ACR) is created that contains the signed HS
* firmware in charge of loading the LS firmwares into their respective
* falcons.
*
* 3) The HS blob is loaded (via its own bootloader) and executed on the
* HS-capable falcon. It authenticates itself, switches the secure falcon to
* HS mode and setup the WPR region around the LS blob (dGPU) or copies the
* LS blob into the WPR region (Tegra).
*
* 4) The LS blob is now secure from all external tampering. The HS falcon
* checks the signatures of the LS firmwares and, if valid, switches the
* managed falcons to LS mode and makes them ready to run the LS firmware.
*
* 5) The managed falcons remain in LS mode and can be started.

* marked as a "secure carveout" and irreversibly locked. Furthermore, the WPR
* secure carveout is also configured to be sent to the GPU via a dedicated

* The FIFO register's lower 4 bits can be used to set the read index into the
* FIFO. After each read of the FIFO register, the read index is incremented.
*
* Indices 2 and 3 contain the lower and upper addresses of the WPR. These are
* stored in units of 256 B. The WPR is inclusive of both addresses.
*
* Unfortunately, for some reason the WPR info register doesn't contain the
* correct values for the secure carveout. It seems like the upper address is
* always too small by 128 KiB - 1. Given that the secure carvout size in the
