2018-08-10arm64: Drop checks for current exception level, hardcode EL3 assumptionJulius Werner
When we first created the arm64 port, we weren't quite sure whether coreboot would always run in EL3 on all platforms. The AArch64 A.R.M. technically considers this exception level optional, but in practice all SoCs seem to support it. We have since accumulated a lot of code that already hardcodes an implicit or explicit assumption of executing in EL3 somewhere, so coreboot wouldn't work on a system that tries to enter it in EL1/2 right now anyway. However, some of our low level support libraries (in particular those for accessing architectural registers) still have provisions for running at different exception levels built-in, and often use switch statements over the current exception level to decide which register to access. This includes an unnecessarily large amount of code for what should be single-instruction operations and precludes further optimization via inlining. This patch removes any remaining code that dynamically depends on the current exception level and makes the assumption that coreboot executes at EL3 official. If this ever needs to change for a future platform, it would probably be cleaner to set the expected exception level in a Kconfig rather than always probing it at runtime.

2018-08-10arm64: Remove set_cntfrq() functionJulius Werner
CNTFRQ_EL0 is a normal AArch64 architectural register like hundreds of others that are all accessed through the raw_(read|write)_${register}() family of functions. There's no reason why this register in particular should have an inconsistent accessor, so replace all instances of set_cntfrq() with raw_write_cntfrq_el0() and get rid of it.

2018-08-09mb/google/octopus: add support for fetching DRAM part number from CBIAaron Durbin
Add 3 new Kconfig options: DRAM_PART_NUM_IN_CBI DRAM_PART_NUM_ALWAYS_IN_CBI DRAM_PART_IN_CBI_BOARD_ID_MIN These control whether to 1. attempt to use CBI at all 2. always use cbi and 3. conditionally use cbi based on board id. The intent is that the MIN variant would be used for the tranisition period then cut over to ALWAYS after full transition. Since multiple OEMs have different schedules these options are there to bridge the gap. yorp. bip, and octopus build targets would never flip DRAM_PART_NUM_IN_CBI, but in case someone does the MIN values are 255 to always take the old path.

2018-08-09rk3288: Dig up two more KB of SRAM from under the couch cushionsJulius Werner
RK3288 has always been notoriously low on SRAM, to the point where its boards have less than 100 bytes left in both their bootblock/verstage sections. This becomes a problem every time we try to add a tiny amount of code to common coreboot interfaces that are included in them. This patch manages to add another KB to each, one from the CBMEM console (which now might get cut off a bit, but that's life) and one by moving the TTB_SUBTABLES to PMUSRAM. PMUSRAM is a weird world where write accesses must always be exactly 4 bytes long or they hang the CPU, so we mostly ignore it... but thankfully, page table entries are exactly 4 bytes long and that's the only thing we write to this region, so it works out in this case.

2018-08-08soc/intel/apollolake: add new dimm info saving APIAaron Durbin
The current call for saving dimm info passed the lpddr4_cfg and memory sku id. In order to prepare decoupling the part number from lpddr4_cfg provide a new API, save_lpddr4_dimm_info_part_num(), which explicitly takes the part number. The previous API now uses the new one internally.

2018-08-08soc/intel/apollolake: Add support for LPDDR4 nWR settingRavi Sarawadi
nWR (Write-Recovery for AutoPre-charge commands), the programmed value of nWR is the number of clock cycles the LPDDR4-SDRAM device uses to determine the starting point of an internal Pre-charge operation after a Write burst with AP (auto-pre-charge) enabled. For >2133MHz speed parts the nWR needs to be set to 24 clock cycles. The nWR field, though, is only in the GLK FSP, so just update that field conditionally based on the GLK Kconfig option.

In procedure generate_cpu_entries(), the code was copied from code that could change variables "plen" and "pcontrol_blk" based on number of cores.

2018-08-07arch: Retire cache_sync_instructions() from <arch/cache.h> (except arm)Julius Werner
cache_sync_instructions() has been superseded by arch_program_segment_loaded() and friends for a while. There are no uses in common code anymore, so let's remove it from <arch/cache.h> for all architectures. arm64 still has an implementation and one reference, but they are not really needed since arch_program_segment_loaded() does the same thing already. Remove them. Leave it in arm(32) since there are several references (including in SoC code) that I don't feel like tracking down and testing right now.
