AMD family 17h and newer don't use cache as RAM, since the RAM is already initialized by the PSP when the x86 cores are released from reset.

2020-08-24mrc_cache: Add mrc_cache fetch functions to support non-x86 platformsShelley Chen
Create two new functions to fetch mrc_cache data (replacing mrc_cache_get_current): - mrc_cache_load_current: fetches the mrc_cache data and drops it into the given buffer. This is useful for ARM platforms where the mmap operation is very expensive. - mrc_cache_mmap_leak: fetch the mrc_cache data and puts it into a given buffer. This is useful for platforms where the mmap operation is a no-op (like x86 platforms). As the name mentions, we are not freeing the memory that we allocated with the mmap, so it is the caller's responsibility to do so. Additionally, we are replacing mrc_cache_latest with mrc_cache_get_latest_slot_info, which does not check the validity of the data when retrieving the current mrc_cache slot. This allows the caller some flexibility in deciding where they want the mrc_cache data stored (either in an mmaped region or at a given address).

2020-08-21soc/amd/common: add rudimentary ATIF supportAaron Durbin
The Linux kenerl driver for AMD gpu currently has a floor value of 12 for brightness settings (AMDGPU_DM_DEFAULT_MIN_BACKLIGHT). AMD indicates they did this because they were concerned with certain panels flickering at lower backlight values. However, for unaffected panels it's desirable to be able to have the panel "turn off" at the lowest backlight setting. The only way to do that is to provide ATIF bindings that indicate backlight range. Option SOC_AMD_COMMON_BLOCK_GRAPHICS_ATIF is added to provide a full range for the backlight setting. If needed, this path can be built upon for fuller support, but for the time being this is the only thing necessary to make the backlight be full range.

2020-07-27soc/amd/common: Move spi access functions into their own fileMartin Roth
Because there was a lot of discussion about the size increase, I also looked at the impact of calling the get_spi_bar() function vs reading spi_base directly and just not worring about whether or not spi_base was already set. Using the spi_base variable directly is 77 bytes bytes for all 6 functions. it's roughly double the size to call the function at 153 bytes. This was almost entirely due to setting up a call stack. If we add an assert into each function to make sure that the spi_base variable is set, it doubles from the size of the function call to 333 bytes. For my money, the function call is the best bet, because it not only protects us from using spi_base before it's set, it also gets the value for us (at least on x86, on the PSP, it still just dies.)

eSPI interrupts are active level high. The eSPI polarity register in the chipset inverts incoming signals if the corresonding bit is 0 in the register. Therefore, all active high (edge or level) virtual wire interrupts need to ensure they are not inverted. And really the sender of the interrupts should be conforming to the the eSPI spec. As such inverting any signals should not be necessary, but this register in the chipset allows for fixing up those misbehaviors.

2020-06-30soc/amd/gpio, mb/{amd,google}: Configure pads using a single entry in GPIO ↵Furquan Shaikh
configuration table Currently, for Stoneyridge and Picasso mainboards, pads that are configured for SCI/SMI/WAKE need to have multiple entries in the configuration table - one for PAD_GPI and other for the special configuration that is required. This requires a very specific ordering of pads within the table and is prone to errors because of conflicting params provided to the different entries for the same pad. This also does not work very well with the concept of override GPIOs where the entry in base table is overridden with the first matched entry from the override table. This change updates the way GPIO configuration is handled for special routing like SCI/SMI/WAKE/DEBOUNCE by setting the control field of soc_amd_gpio structure in the macros performing these configurations. Also, program_gpios() is updated to perform a write to GPIO control register instead of read-modify-write. This is because mainboard is expected to provide only a single configuration entry for each pad within a given table. Thus, there is no need to preserve earlier configuration. Mainboards that were providing multiple entries for a single pad are updated accordingly.

2020-06-25Revert "soc/amd/common/block/acpimmio: Update acpimmio for psp_verstage"Kyösti Mälkki
This reverts commit 4883252912665f56c8e7801fe03a26594a1e9d5d. Almost everything in <amdblocks/acpimmio_map.h> is invalid for PSP as it does not have the same view of memory space. The prototypes xx_set/get_bar() are only valid for PSP as x86 cores will use the constant mapping defined in <amdblocks/acpimmio_map.h> The selected MMIO base address model depends of the architecture the stage is built for and, to current knowledge, nothing else. So the guards should have been with ENV_X86 vs ENV_ARM and not about CONFIG(VERSTAGE_BEFORE_BOOTBLOCK). For the ENV_ARM stage builds, <arch/io.h> file referenced in the previously added mmio_util_psp.c file has not been added to the tree. So there was some out-of-order submitting, which did not get caught as the build-testing of mixed-arch stages has not been incorporated into the tree yet. The previously added file mmio_util_psp.c is also 90% redundant with mmio_util.c.

2020-06-23src/*: Update makefiles to exclude x86 code from psp-verstageMartin Roth
The assumption up to this point was that if the system had an x86 processor, verstage would be running on the x86 processor. With running verstage on the PSP, that assumption no longer holds true, so exclude pieces of code that cause problems for verstage on the PSP. This change will add these files to verstage only if the verstage architecture is X86 - either 32 or 64 bit.
