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).

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.)

2020-07-20src: Drop useless GPE1 settings from FADTAngel Pons
None of the currently-supported chips has a GPE1 block. The ACPI spec, version 6.3, section 4.8.1.6 (General-Purpose Event Registers) says: If a generic register block is not supported then its respective block pointer and block length values in the FADT table contain zeros. Since the FADT struct defaults to zero in coreboot, we don't need to do anything with GPE1 for now. So, drop the unneeded writes to GPE1 fields. Tested on Asus P8Z77-V LX2 with Linux 5.7.6 and Windows 10 at the end of the patch train, both operating systems are able to boot successfully.
