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.
