Summary of Steps from the Spec (Spreadsheet)
+ (Aa) Steps 0,1,2,3a [need to identify parameterization]
+ (Ab) Step 3b [PMGR: set Freq to 50MHz & delay-wait]
+ (Ac) Steps 3c,4,5 [need to identify parameterization]
+ (B) Step 6 [Change Clk Speed]
+ (C) Step 7 [include delay-wait from early Step 8]
+ (D) Step 8a [Cal: CA 800MHz Vmin]
+ (E) Step 8b [Write Regs]
+ (F) Step 8c [Cal: CA 800MHz Vmin] (...again? should it be CS?)
+ (G) Step 8d [Write Regs]
+ (H) Step 9 [Write Regs]
+ (I) Step 10 [Cal: WrLvl, RdDq, WrDq 800MHz Vmin]
+ (J) Step 11 [Write Regs]
+ (K) Step 12 [Cal: CA 1200MHz Vnom]
+ (L) Step 13 [Write Regs]
+ (M) Step 14 [Cal: WrLvl, RdDq, WrDq 1200MHz Vmin]
+ (N) Steps 15,16,17,18,19,20 [need to identify parameterization]
Between these steps there is possibly a need/desire for:
- Frequency Changes (PMGR)
- PMU save/restore
- debug messages
- register dumps (DV, SiVal)
- anything else!
CONFIG Table:
Compile-Time Known:
Type of Execution Environment CoreOS, DV, SiVal
Type of Target SoC, FPGA, Palladium
ChipID 0x8000, 0x8001, etc.
Revision A0, B0, B1, etc.
Num DCS 4, 8, etc. (Derived...!)
Variant Flags Work-arounds, RADAR Ref., et al.
(Config Info know at Compile time can be subject to #if)
Run-Time Known:
Type of Init ColdBoot, AOP_DDR, AOP_AWAKE
Debug Flags Low-Level, Milestone, et al.
RegValue Table
Much like today's: various values for various registers
Sensitive to ChipID (also Target type?)
(Internal static alloc (Complete Table Fill-in within Init function):
Fill in Values (per ChipID/Rev & Target-type)
return pointer to caller
(Allows customization by caller before use)
TODO:
- Convert to using SPDS for register names, et al
