2020-09-16drivers/spi/tpm: Improve error checkingCaveh Jalali
This adds error checking in paths that previously ignored TPM communication errors. We hit this case occasionally during "Checking cr50 for pending updates"; previously we would go down this path and eventually time out using MAX_STATUS_TIMEOUT, which is 2 minutes. Now, we detect the failure and return with an error indication instead of timing out after a long time. The root cause of the communication error is an open issue.

This change is being done for the following reasons: 1. The CONFIG_ELOG_PRERAM is unused. 2.

With the current timeout of 1000 cycles of 100 microsecond would see timeout occurs on OCP Delta Lake if the log level is set to values smaller than 8. Because the prink(BIOS_SPEW, ..) in ipmi_kcs_status() creates delay and avoid the problem, but after setting the log level to 4 we see some timeout occurs. The unit is millisecond and the default value is set to 5000 according to IPMI spec v2.0 rev 1.1 Sec. 9.15, a five-second timeout or greater is recommended. Tested=On OCP Delta Lake, with log level 4 cannot observe timeout occurs.

2020-09-09drivers/aspeed/common: Support disabled P2A bridgePatrick Rudolph
This ports Linux commit 71f677a91046599ece96ebab21df956ce909c456 "Handle configuration without P2A bridge". Quote: The ast driver configures a window to enable access into BMC memory space in order to read some configuration registers. If this window is disabled, which it can be from the BMC side, the ast driver can't function. Closing this window is a necessity for security if a machine's host side and BMC side are controlled by different parties; i.e. a cloud provider offering machines "bare metal". P2A stands for primary to AHB. Tested on Prodrive Hermes, which uses an AST2500. The machine still boots, has a high resolution framebuffer working in EDK2, and its boot time has been reduced by 2.5 seconds as it no longer runs into a timeout due to disabled P2A bridge.

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).

2020-08-03drivers/intel/mipi_camera: Add reference counting for shared resourcesSugnan Prabhu S
This change updates the mipi_camera driver to handle shared power resource between multiple cameras. This is achieved by adding a guard variable and methods to manipulate the guard variable before calling the actual platform method which enables or disables the resource. PowerResource will call these guarded methods to enable or disable the resource. This protects the shared resource from being enabled or disabled multiple times while the other camera is using the resource. Example: Consider a platform where two cameras are sharing a GPIO resource 0xXX and both the cameras calls enable and disable guarded methods for this GPIO. Actual platform disable method for the GPIO is called only after the last camera using the GPIO calls DSBx method and RESx becomes 0.

2020-07-02acpi_device: Replace polarity with active_low in acpi_gpio for GpioIoFurquan Shaikh
As per ACPI spec, GpioIo does not have any polarity associated with it. Linux kernel uses `active_low` argument within GPIO _DSD property to allow BIOS to indicate if the corresponding GPIO should be treated as active low. Thus, if GPIO has active high polarity or if it does not have any polarity associated with it, then the `active_low` argument is supposed to be set to 0. Having a `polarity` field in acpi_gpio seems confusing because GPIOs might not always have polarity associated with them. Example, in case of DMIC-select GPIO where 0 means select DMIC0 and 1 means select DMIC1, there is no polarity associated with the GPIO. Thus, it would be clearer for mainboard to use macros without having to specify a particular polarity. In order to enable mainboards to provide GPIO information without polarity for GpioIo usage, this change also adds `ACPI_GPIO_OUTPUT` and `ACPI_GPIO_INPUT` macros.
