espi_poll_status describes better what the function actually does, since it polls the status register instead of just doing a single read to check.

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.)

2020-07-24soc/amd/picasso/fsp_params: add asserts for descriptor countFelix Held
With the updated FSP UPD headers there are enough DXIO descriptor slots in the UPD, so we can now add asserts to make sure that the mainboard doesn't pass more DXIO/DDI descriptors than the UPD has slots for. This is part of the DXIO/DDI descriptor handling cleanup.

2020-07-20src: Make HAVE_CF9_RESET set the FADT reset registerAngel Pons
All supported x86 chips select HAVE_CF9_RESET, and also use 0xcf9 as reset register in FADT. How unsurprising. We might as well use that information to automatically fill in the FADT accordingly. So, do it. To avoid having x86-specific code under arch-agnostic `acpi/`, create a new optional `arch_fill_fadt` function, and override it for x86 systems. 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.

2020-07-20amd/{hudson,stoney,picasso}: Drop PM2 settings from FADTAngel Pons
The PM2_CNT register block is no longer needed, as explained in some comments. While they may have been copy-pasted around a lot, they are at least true for Hudson, and it makes sense to assume that they are true for newer chipsets as well. As per the ACPI specification, version 6.3, section 4.8.1.3 (PM2 Control Register): This register block is optional, if not supported its block pointer and length contain a value of zero. Since the FADT struct defaults to zero in coreboot, we don't need to do anything to indicate PM2_CNT is not supported. So, drop unneeded values.
