Code for secure/non-secure ctxsw booting spread across gr_gk20a.c
and gr_gm20b.c. With this change this code is move to gr falcon unit.
Ctxsw loading is now supported with 2 supported common functions:
1.Non secure boot:
int nvgpu_gr_falcon_load_ctxsw_ucode(struct gk20a *g);
2.Secure boot:
int nvgpu_gr_falcon_load_secure_ctxsw_ucode(struct gk20a *g);
Now gr ops function "int (*load_ctxsw_ucode)(struct gk20a *g);" is moved to
gr falcon ops and in chip hals it is set with secure/non-secure booting.
Non-secure booting: nvgpu_gr_falcon_load_ctxsw_ucode support ctxsw loading
in 2 methods: bit-banging uode or booting with bootloader
A. Common and hal functions for non-secure bit-banging ctxsw loading:
Common: static void nvgpu_gr_falcon_load_dmem(struct gk20a *g) ->
Hals: void (*load_gpccs_dmem)(struct gk20a *g,i
const u32 *ucode_u32_data, u32 size);
void (*load_fecs_dmem)(struct gk20a *g,
const u32 *ucode_u32_data, u32 size);
Common: static void nvgpu_gr_falcon_load_imem(struct gk20a *g) ->
Hals: void (*load_gpccs_imem)(struct gk20a *g,
const u32 *ucode_u32_data, u32 size);
void (*load_fecs_imem)(struct gk20a *g,
const u32 *ucode_u32_data, u32 size);
Other basic HALs:
void (*configure_fmodel)(struct gk20a *g); -> configure fmodel for ctxsw loading
void (*start_ucode)(struct gk20a *g); -> start running ctxcw ucode
B.Common and hal functions for non-secure ctxsw loading with bootloader
First get the ctxsw ucode using: nvgpu_gr_falcon_init_ctxsw_ucode, then
Common: static void nvgpu_gr_falcon_load_with_bootloader(struct gk20a *g)
void nvgpu_gr_falcon_bind_instblk((struct gk20a *g) ->
Hal: void (*bind_instblk)(struct gk20a *g, struct nvgpu_mem *mem, u64 inst_ptr);
Common: nvgpu_gr_falcon_load_ctxsw_ucode_segments ->
nvgpu_gr_falcon_load_ctxsw_ucode_header ->
nvgpu_gr_falcon_load_ctxsw_ucode_boot for both fecs and gpccs ->
Hals: void (*load_ctxsw_ucode_header)(struct gk20a *g, u32 reg_offset,
u32 boot_signature, u32 addr_code32, u32 addr_data32,
u32 code_size, u32 data_size);
void (*load_ctxsw_ucode_boot)(struct gk20a *g, u64 reg_offset, u32 boot_entry,
u32 addr_load32, u32 blocks, u32 dst);
Other basic HAL to get gpccs start offset:
u32 (*get_gpccs_start_reg_offset)(void);
C.Secure booting is support with gpmu and acr and with following additional
common function in gr falcon.
static void nvgpu_gr_falcon_load_gpccs_with_bootloader(struct gk20a *g) ->
nvgpu_gr_falcon_bind_instblk and nvgpu_gr_falcon_load_ctxsw_ucode_segments
Additional basic hals:
void (*start_gpccs)(struct gk20a *g);
void (*start_fecs)(struct gk20a *g);
Following ops from gr is removed, since it is not required to set by chip hals:
void (*falcon_load_ucode)(struct gk20a *g, u64 addr_base,
struct gk20a_ctxsw_ucode_segments *segments, u32 reg_offset);
Now this is handled by static common function:
static int nvgpu_gr_falcon_copy_ctxsw_ucode_segments( struct gk20a *g,
struct nvgpu_mem *dst, struct gk20a_ctxsw_ucode_segments *segments,
u32 *bootimage, u32 *code, u32 *data)

Move functions related to init_ctxsw_ucode to common
falcon from gr_gk20a.c. Modified code to call this new
function and modified function names in common falcon
to reflect new re-org.
