amdgpu_mes, which is a driver scope parameter, is used
to whether enable mes or not.
MES (Micro Engine Scheduler) is the new on chip hw scheduling
microcontroller. It can be used to handle queue scheduling and
preemption and priorities.

SDMA (System DMA) is a general purpose DMA engine usable
by UMDs for transfers or the kernel for paging or GPUVM
updates.
v1: support basic funcitonalites includes rb, ib, vm,
copy buffer and trap irq
v2: convert to use new get_vm_pde in emit_vm_flush
v3: retire amdgpu_ttm_set_active_vram_size from sdma v5
v4: retire the redundant hdp_invalidate implementation
v5: squash in updates

psp will write a header to vram, but the value exposed in
RCC_CONFIG_MEMSIZE does not include the memory that this header is
written to. Therefore, the interpretation of the table does not need to
take the psp header into account.

The IP discovery table lists is populated by the psp at power on
and includes all of the hw details on the board:
- List of IPs and MMIO offsets
- IP harvest details
- IP configuration details
v2: prefix struct and function names with 'amdgpu'
v3: read table binary from vram using mmMM_INDEX and mmMM_DATA
update TABLE_BINARY_MAX_SIZE to 64kb (1 TMR)
add 'instance_number' field per ip info
consider endianness and replace uint8/16/32_t with u8/16/32
initialize register base addresses
initialize adev->gfx.config and adev->gfx.cu_info to replace gpu info fw
get major and minor version using a single api
don't expose internal data structures in amdgpu_discovery.h
v4: RCC_CONFIG_MEMSIZE is in MB units
hold mmio_idx_lock while reading ip discovery binary
v5: pick out discovery.h as a cross-OS header
do structure pointer cast directly
consider endianness while using the member of structure
convert base addresses to dword
at boot up, PSP BL copies ip discovery binary from VBIOS(SPIROM) image to the
top of the frame buffer (just below the reserved regions for PSP & SMU).
ip discovery data table includes the collection of each ip's identification
number, base addresses, version number, and harvest setting placeholder.
gc data table includes gfx info structure.

Since from navi10, the tmr_size should be decided by psp sos according to
toc header. Driver should issue LOAD_TOC to psp sos to get the tmr_size needed.
The allocation of tmr_size then should be done only when sos/sysdrv loading
completed
Accordingly, asd_init also move to psp_hw_start after sos fw loading to make
calling sequence consistent.
