/**
 * Test specification for: test_fifo_init_support
 *
 * Description: The FIFO unit shall initialize all sub-units.
 *
 * Test Type: Feature
 *
 * Targets: nvgpu_fifo_init_support, nvgpu_fifo_cleanup_sw_common
 *
 * Input: None
 *
 * Steps:
 * - Setup gv11b register spaces for MASTER, TOP, FIFO, PBDMA, CCSR
 *   and USERMODE. This allows some HAL to read emulated values of gv11b
 *   registers.
 * - Init HAL for to use gv11b defaults
 * - Stub some HALs that would require reg access
 *   - g->ops.gr.init.get_no_of_sm
 * - Also stub the following HAL, since BAR1 is not initialized,
 *   and USERD not used in safety build
 *   - g->ops.userd.setup_sw
 * - Additionnaly the following HALs are set to NULL, as currenty
 *   not needed for subsequent tests.
 *   - g->ops.fifo.init_fifo_setup_hw = NULL;
 *   - g->ops.tsg.init_eng_method_buffers = NULL;
 * - Call nvgpu_fifo_init_support
 * - Cleanup gv11b register spaces.
 *
 * Output: Returns PASS if FIFO unit could be initialized. FAIL otherwise.
