-/*
- * 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.

- * gm20b_secboot_tegra_read_wpr() - read the WPR registers on Tegra
- *
- * On dGPU, we can manage the WPR region ourselves, but on Tegra this region
- * is allocated from system memory by the secure firmware. The region is then
- * 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
- * serial bus between the memory controller and the GPU. The GPU requests this
- * information upon leaving reset and exposes it through a FIFO register at
- * offset 0x100cd4.
- *
- * 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
- * memory controller configuration is specified in units of 128 KiB, it's
- * possible that the computation of the upper address of the WPR is wrong and
- * causes this difference.
