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.)

None of the currently-supported chips has PM1b_EVT nor PM1b_CNT event register blocks. According to the ACPI specification, version 6.3, sections 4.8.1.1 and 4.8.1.2 (PM1 Event/Control Registers): If the PM1b_EVT_BLK is not supported, its pointer contains a value of zero in the FADT. If the PM1b_CNT_BLK is not supported, its pointer contains a value of zero in the FADT. Since the FADT struct defaults to zero in coreboot, we don't need to do anything with PM1b for now. So, drop unneeded writes to PM1b 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.

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.

2020-07-02soc/amd/common: fix SPI bar resource usageAaron Durbin
The ACPI code was not masking off the correct bits for publishing the SPI bar to the OS. It resulted in a dmesg messagelike: system 00:00: [mem 0xfec10002-0xfec11001] has been reserved And /proc/iomem entry fec10002-fec11001 : pnp 00:00 These addresses are wrong because they are including bits of a register that are not a part of the address. Moreover, the code does not publish the eSPI register area either. The eSPI registers live at 0x10000 added to the SPI bar. Lastly, both regions are less than a page so only report a page of usage for each. Stoney Ridge's SPI bar register defines the address as 31:6 while Picasso's SPI bar register defines the address as 31:8. Use Picasso's valid mask for both cases because no one is assigning addresses that are aligned to less than 256 bytes.

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.
