2021-01-15nb/intel/sandybridge: Clarify command timing calculationAngel Pons
Command timing is the absolute value of the most negative `pi_coding` value across all ranks, or zero if there are no negative values. Use the MAX() macro to ease proving that `cmd_delay` can never be negative, and then drop the always-false underflow check. The variable type for `cmd_delay` still needs to be signed because of the comparisons with `pi_coding`, which is a signed value. Using an unsigned type would result in undefined and also undesired behavior.

2021-01-15nb/intel/sandybridge: Fix handling of clock timingAngel Pons
Clock is a differential signal and propagates faster than command and control, therefore its timing needs to be offset with `pi_code_offset`. It is also a periodic signal, so it can safely wrap around. To avoid potential undefined behavior, make `clk_delay` signed. It makes no difference with valid values, because the initial value can be proven to never be negative and `pi_code_offset` is always positive. With this change, it is possible to add an underflow check, for additional sanity.

2021-01-06nb/intel/sandybridge: Define and use `QCLK_PI` constantAngel Pons
To allow adjusting the phase shift of the various I/O signals, the memory controller contains several PIs (Phase Interpolators). These devices subdivide a QCLK (quarter of a clock cycle) in 64 `ticks`, and the desired phase shift is specified in a register. For shifts larger than one QCLK, there are `logic delay` registers, which allow shifting a whole number of QCLKs in addition to the PI phase shift. The number of PI ticks in a QCLK is often used in raminit calculations. Define the `QCLK_PI` macro and use it in place of magic numbers. In addition, add macros for other commonly-used values that use `QCLK_PI` to avoid unnecessarily repeating `2 * QCLK_PI`, such as `CCC_MAX_PI`. Tested with BUILD_TIMELESS=1, Asus P8Z77-V LX2 does not change.

2020-12-12nb/intel/sandybridge: Fix blunder in MR2 shadow codeAngel Pons
Commit 7f1363d9b4 (nb/intel/sandybridge: Program MR2 shadow register) has a bug where the system locks up and power cycles when booting Linux, but is still able to pass memtest86+ with flying colors. The issue will occur when the following conditions are true: - CPU is Ivy Bridge - Memory speed is not greater than 1066 MHz (DDR3-2133 or slower) - System contains dual-rank DIMMs - The second rank of the dual-rank DIMMs is mirrored - All DIMMs support Extended Temperature Range - At least one of the DIMMs does not support Auto Self-Refresh If all of these conditions are met, the final value of the MR2 Shadow registers configures the memory controller to issue a MRS command to update MR2 before entering self-refresh mode, but indicates that rank mirroring is not required (the first rank on a DIMM is never mirrored). Before the memory controller enters self-refresh, it sends MRS commands to all ranks to update MR2, but the missing address and bank mirroring means DRAM chips on mirrored ranks instead clobber MR1 with junk data. With garbage in MR1, the mirrored ranks no longer function properly, which ultimately leads to all hell breaking loose (undefined behavior). The condition is backwards, since only odd ranks can be mirrored. To avoid this problem completely, simply remove the condition. The final register value will still be correct, since the bits are always ORed. Tested on Asus P8Z77-V LX2, fixes booting Linux with dual-rank DIMMs. Change-Id: Iceff741eb85fab0ae846e50af0080e5ff405404c Signed-off-by: Angel Pons <th3fanbus@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/48550 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Nico Huber <nico.h@gmx.de> Reviewed-by: Arthur Heymans <arthur@aheymans.xyz> Reviewed-by: Patrick Rudolph <siro@das-labor.org>

2020-12-02cbfs: Simplify load/map API names, remove type argumentsJulius Werner
This patch renames cbfs_boot_map_with_leak() and cbfs_boot_load_file() to cbfs_map() and cbfs_load() respectively. This is supposed to be the start of a new, better organized CBFS API where the most common operations have the most simple and straight-forward names. Less commonly used variants of these operations (e.g. cbfs_ro_load() or cbfs_region_load()) can be introduced later. It seems unnecessary to keep carrying around "boot" in the names of most CBFS APIs if the vast majority of accesses go to the boot CBFS (instead, more unusual operations should have longer names that describe how they diverge from the common ones). cbfs_map() is paired with a new cbfs_unmap() to allow callers to cleanly reap mappings when desired. A few new cbfs_unmap() calls are added to generic code where it makes sense, but it seems unnecessary to introduce this everywhere in platform or architecture specific code where the boot medium is known to be memory-mapped anyway. In fact, even for non-memory-mapped platforms, sometimes leaking a mapping to the CBFS cache is a much cleaner solution than jumping through hoops to provide some other storage for some long-lived file object, and it shouldn't be outright forbidden when it makes sense. Additionally, remove the type arguments from these function signatures. The goal is to eventually remove type arguments for lookup from the whole CBFS API. Filenames already uniquely identify CBFS files. The type field is just informational, and there should be APIs to allow callers to check it when desired, but it's not clear what we gain from forcing this as a parameter into every single CBFS access when the vast majority of the time it provides no additional value and is just clutter.

2020-11-22nb/intel/sandybridge: Refine power-down mode logicAngel Pons
When memory is running at fast frequencies, power-down modes can lessen system stability. Check tXP and tXPDLL values and use safer power down modes if their values are high. Do not use APD with DLL-off on mobile: vendor firmware does not use it, and it can influence system stability.

2020-11-22nb/intel/sandybridge: Use one sequence for write levelingAngel Pons
In order to run a write leveling test, one needs to unset the Qoff bit in MR1, then run the test, and finally set Qoff again. The current IOSAV sequence uses two subsequences to perform the test, while the other two are unused. It is possible to perform the two necessary MR1 updates in the same sequence, which can potentially improve runtime (not measured). Since `write_mrreg` is no longer used, it is necessary to handle address mirroring explicitly. This can be accomplished with the recently-added `ddr3_mirror_mrreg` function, which is also used in `write_mrreg`. Tested on Asus P8H61-M PRO, still boots.
