2020-12-08coreboot tables: Add SPI flash memory map windows to coreboot tablesFurquan Shaikh
This change adds details about the memory map windows to translate addresses between SPI flash space and host address space to coreboot tables. This is useful for payloads to setup the translation using the decode windows already known to coreboot. Until now, there was a single decode window at the top of 4G used by all x86 platforms. However, going forward, platforms might support more decode windows and hence in order to avoid duplication in payloads this information is filled in coreboot tables. `lb_spi_flash()` is updated to fill in the details about these windows by making a call to `spi_flash_get_mmap_windows()` which is implemented by the driver providing the boot media mapping device.

2020-12-03spi/flashconsole: Fix internal buffer overflowNico Huber
Once the console's FMAP region is full, we stop clearing the line buffer and `line_offset` is not reset anymore. Hence, sanity check `line_offset` everytime before writing to the buffer. The issue resulted in boot hangs and potentially a brick if the log was very verbose.

We have to do so, because the SoC is not guaranteed to detect pulses shorter than 100us in S0i3.4 substate. A new Kconfig setting CR50_USE_LONG_INTERRUPT_PULSES controls new code running in verstage, which will program a new Cr50 register, provided that Cr50 firmware is new enough to support the register.

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.

Having speparate types for the status register with three and four block protection bits respectively doesn't really make sense, it's the same size either way just a different representation, so one union type will do. This allows us to de-duplicate the status register read in winbond_get_write_protection as well as removing another layer of union in 'struct status_regs'.

2020-04-23rules.h: Rename ENV_VERSTAGE to ENV_SEPARATE_VERSTAGEJulius Werner
When CONFIG_SEPARATE_VERSTAGE=n, all verstage code gets linked into the appropriate calling stage (bootblock or romstage). This means that ENV_VERSTAGE is actually 0, and instead ENV_BOOTBLOCK or ENV_ROMSTAGE are 1. This keeps tripping up people who are just trying to write a simple "are we in verstage (i.e. wherever the vboot init logic runs)" check, e.g. for TPM init functions which may run in "verstage" or ramstage depending on whether vboot is enabled. Those checks will not work as intended for CONFIG_SEPARATE_VERSTAGE=n. This patch renames ENV_VERSTAGE to ENV_SEPARATE_VERSTAGE to try to clarify that this macro can really only be used to check whether code is running in a *separate* verstage, and clue people in that they may need to cover the linked-in verstage case as well.

2020-01-10drivers/spi/spi_flash: explicitly handle STMicro deep power stateAaron Durbin
In order to provide more consistent probing in future refactorings, pull out the release from deep sleep path in STMicro's SPI flash probing function. Call that function explicitly when RDID doesn't return anything at all. The old STMicro parts, even if supporting RDID, won't decode that instruction while in a deep power down state. Instead of re-issuing RDID after the successful wake assume the id fixup is valid.

2019-12-11printf: Automatically prefix %p with 0xJulius Werner
According to the POSIX standard, %p is supposed to print a pointer "as if by %#x", meaning the "0x" prefix should automatically be prepended. All other implementations out there (glibc, Linux, even libpayload) do this, so we should make coreboot match. This patch changes vtxprintf() accordingly and removes any explicit instances of "0x%p" from existing format strings. How to handle zero padding is less clear: the official POSIX definition above technically says there should be no automatic zero padding, but in practice most other implementations seem to do it and I assume most programmers would prefer it. The way chosen here is to always zero-pad to 32 bits, even on a 64-bit system. The rationale for this is that even on 64-bit systems, coreboot always avoids using any memory above 4GB for itself, so in practice all pointers should fit in that range and padding everything to 64 bits would just hurt readability. Padding it this way also helps pointers that do exceed 4GB (e.g. prints from MMU config on some arm64 systems) stand out better from the others.

2019-08-20src: Remove variable length arraysJacob Garber
Variable length arrays were a feature added in C99 that allows the length of an array to be determined at runtime. Eg. int sum(size_t n) { int arr[n]; ... } This adds a small amount of runtime overhead, but is also very dangerous, since it allows use of an unlimited amount of stack memory, potentially leading to stack overflow. This is only worsened in coreboot, which often has very little stack space to begin with. Citing concerns like this, all instances of VLA's were recently removed from the Linux kernel. In the immortal words of Linus Torvalds [0], AND USING VLA'S IS ACTIVELY STUPID! It generates much more code, and much _slower_ code (and more fragile code), than just using a fixed key size would have done. [...] Anyway, some of these are definitely easy to just fix, and using VLA's is actively bad not just for security worries, but simply because VLA's are a really horribly bad idea in general in the kernel. This patch follows suit and zaps all VLA's in coreboot. Some of the existing VLA's are accidental ones, and all but one can be replaced with small fixed-size buffers. The single tricky exception is in the SPI controller interface, which will require a rewrite of old drivers to remove [1].

This feature needs to be supported by both the flash chip and the controller, so we add a new dual_spi flag (and a new flags field to hold it) to the spi_flash structure and a new optional xfer_dual() function pointer to the spi_ctrlr structure. When both are provided, Dual SPI mode is used automatically, otherwise things work as before. This patch only adds the dual_spi flag exemplary to all Winbond and Gigadevice chips, other vendors need to be added as needed.

2019-06-10spi_flash: Make .read() callback optionalJulius Werner
All SPI flash chip drivers currently in coreboot use the generic read functions (spi_flash_cmd_read_fast()/_slow()) as their read callback. The only use case for specialized read callbacks we have left is with specialized flash controllers like Intel fast_spi (which sort of impersonate the flash chip driver by implementing their own probe function). This patch unifies the behavior for all normal flash drivers by making the read callback optional and letting them all fall back to a default read implementation that handles normal fast/slow reading. Most of the drivers used to install the respective callback after checking CONFIG_SPI_FLASH_NO_FAST_READ, but some hardcoded either slow or fast writes. I have found no indications for why this is and spot-checked datasheets for affected vendors to make sure they all support both commands, so I assume this is just some old inaccuracy rather than important differences that need preserving. (Please yell if you disagree.) Also take the opportunity to refactor some of the common spi_flash.c code a bit because I felt there are too many nested functions that don't really do enough on their own, and centralizing stuff a bit should make it easier to follow the code flow. (Some of this is in preparation for the next patch.)

2019-02-22symbols.h: Add macro to define memlayout region symbolsJulius Werner
When <symbols.h> was first introduced, it only declared a handful of regions and we didn't expect that too many architectures and platforms would need to add their own later. However, our amount of platforms has greatly expanded since, and with them the need for more special memory regions. The amount of code duplication is starting to get unsightly, and platforms keep defining their own <soc/symbols.h> files that need this as well. This patch adds another macro to cut down the definition boilerplate. Unfortunately, macros cannot define other macros when they're called, so referring to region sizes as _name_size doesn't work anymore. This patch replaces the scheme with REGION_SIZE(name). Not touching the regions in the x86-specific <arch/symbols.h> yet since they don't follow the standard _region/_eregion naming scheme. They can be converted later if desired.

2019-02-20drivers/spi/spi_flash.c: Avoid static scan false positiveRichard Spiegel
Static scan-build indicates a possible invalid return from function spi_flash_cmd_erase(). The root cause is because the scan believes it's possible for offset to be above the end address in the first pass, thus not setting a value for variable ret. Assign initial value of -1 to variable ret to make checker happy.
