2021-04-06nb/intel/haswell: Ensure MCH has acked raminitAngel Pons
Haswell MRC.bin can return zero even when raminit did not complete successfully. When this happens, the memory controller will not have acknowledged raminit: the mc_init_done_ack bit in the MC_INIT_STATE_G register will be zero, and memory accesses will lock up the system. To handle this situation more gracefully, check the mc_init_done_ack bit after running MRC. If the bit is not set, log a fatal error and halt. Tested on Asrock B85M Pro4: - With badly-seated DIMMs, MRC raminit fails and coreboot dies. - After reseating the DIMMs, the board still boots successfully.

2021-04-05nb/intel/sandybridge: Drop `pci_mmio_size`Angel Pons
There's no good reason to use values smaller than 2 GiB here. Well, it increases available DRAM in 32-bit space. However, as this is a 64-bit platform, it's highly unlikely that 32-bit limitations would cause any issues anymore. It's more likely to have the allocator give up because memory-mapped resources in 32-bit space don't fit within the specified MMIO size, which can easily occur when using a discrete graphics card.

2021-03-19nb/intel/haswell: Consolidate memory-down SPD handlingAngel Pons
Mainboards do not need to know about `pei_data` to tell northbridge code where to find the SPD data. Adjust `mb_get_spd_map` to take a pointer to a struct instead of an array, and update all the mainboards accordingly. Currently, the only board with memory-down in the tree is google/slippy. Mainboard code now obtains the SPD index in `mb_get_spd_map` and adjusts the channel population accordingly. Then, northbridge code reads the SPD file and uses the index that was read in `mb_get_spd_map`, and copies it to channel 0 slot 0 unconditionally. MRC only uses the first position of the `spd_data` array, and ignores the other positions. In coreboot code, `setup_sdram_meminfo` uses the data of each SPD index, so `copy_spd` has to account for this. Tested on Asrock B85M Pro4, still boots and still resumes from S3.

The platform performs a CPU-only reset after initializing QPI (QuickPath Interconnect) and before actually performing raminit. The state is saved in the sticky scratchpad register at MCHBAR + 0x2ca8. Relocate some QuickPath init to a separate file. All moved functions are only used within QPI init code, and had to be relocated in one commit. Tested on out-of-tree HP 630, still boots.

2021-02-07nb/intel/pineview: Clean up FIXMEs in raminitNico Huber
Using MCHBAR32_AND_OR() in these two cases changes the order of additions slightly. Originally, the MCHBAR offset and the base register offset (0x5a4/0x5b4) were added first. Due to the added parentheses in the register macros, now the complete register offset is calculated first and then added to MCHBAR. Associativity tells us that this doesn't change the result. Changes in the resulting binary were verified manually on the object file.
