2021-01-14build system: Structure and serialize INTERMEDIATEPatrick Georgi
Target added to INTERMEDIATE all operate on coreboot.pre, each modifying the file in some way. When running them in parallel, coreboot.pre can be read from and written to in parallel which can corrupt the result. Add a function to create those rules that also adds existing INTERMEDIATE targets to enforce an order (as established by evaluation order of Makefile.inc files). While at it, also add the addition to the PHONY target so we don't forget it. BUG=chromium:1154313, b:174585424 TEST=Built a configuration with SeaBIOS + SeaBIOS config files (ps2 timeout and sercon) and saw that they were executed.

This change adds support to Lock down the configuration of extended BIOS region. This is done as part of fast_spi_lockdown_cfg() so that it is consistent with the other lockdown. Change includes: 1. New helper function fast_spi_lock_ext_bios_cfg() added that will basically set EXT_BIOS_LOCK.

2020-12-08soc/intel/common/fast_spi: Add support for configuring MTRRsSrinidhi N Kaushik
This change enables caching for extended BIOS region. Currently, caching is enabled for the standard BIOS region upto a maximum of 16MiB using fast_spi_cache_bios_region, used the same function to add the support for caching for extended BIOS region as well. Changes include: 1. Add a new helper function fast_spi_cache_ext_bios_window() which calls fast_spi_ext_bios_cache_range() which calls fast_spi_get_ext_bios_window() to get details about the extended BIOS window from the boot media map and checks for allignment and set mtrr. 2. Make a call to fast_spi_cache_ext_bios_region() from fast_spi_cache_bios_region (). 3. Add new helper function fast_spi_cache_ext_bios_postcar() which does caching ext BIOS region in postcar similar to 1. 4. If the extended window is used, then it enables caching for this window similar to how it is done for the standard window.

2020-12-08soc/intel/common/fast_spi: Add extended decode window supportSrinidhi N Kaushik
This change enables support for configuration of extended BIOS region decode window. This configuration needs to be performed as early as possible in the boot flow. This is required to ensure that any access to the SPI flash region below 16MiB in coreboot is decoded correctly. The configuration for the extended BIOS window if required is done as part of fast_spi_early_init(). Changes include: 1. Make a call to fast_spi_enable_ext_bios() before the bus master and memory space is enabled for the fast SPI controller. 2. Added a helper function fast_spi_enable_ext_bios() which calls fast_spi_get_ext_bios_window() to get details about the extended BIOS window from the boot media map. 3. Depending upon the SPI flash device used by the mainboard and the size of the BIOS region in the flashmap, this function will have to perform this additional configuration only if the BIOS region is greater than 16MiB 4. Adddditionally, set up the general purpose memory range registers in DMI.

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.

2020-12-08soc/intel/common/fast_spi: Add custom boot media deviceFurquan Shaikh
This change enables support for a custom boot media device in fast SPI controller driver if the platform supports additional decode window for mapping BIOS regions greater than 16MiB. Following new Kconfigs are added: 1. FAST_SPI_SUPPORTS_EXT_BIOS_WINDOW: SoC can select this to indicate support for extended BIOS window. 2. EXT_BIOS_WIN_BASE: If FAST_SPI_SUPPORTS_EXT_BIOS_WINDOW is selected, this provides the base address of the host space that is reserved for mapping the extended window. 3. EXT_BIOS_WIN_SIZE: If FAST_SPI_SUPPORTS_EXT_BIOS_WINDOW is selected, this provides the size of the host space reserved for mapping extended window. If platform indicates support for extended BIOS decode window, cbfstool add command is provided additional parameters for the decode window using --ext-win-base and --ext-win-size. It is the responsibility of the mainboard fmap author to ensure that the sections in the BIOS region do not cross 16MiB boundary as the host space windows are not contiguous. This change adds a build time check to ensure no sections in FMAP cross the 16MiB boundary. Even though the platform supports extended window, it depends upon the size of BIOS region (which in turn depends on SPI flash size) whether and how much of the additional window is utilized at runtime. This change also provides helper functions for rest of the coreboot components to query how much of the extended window is actually utilized.

2017-08-17intel/common/block/fast_spi: Add config option to disable write statusDuncan Laurie
Chrome OS systems rely on the write status register to enable/disable flash write protection and disabling this opcode breaks the ability to enable or disable write protection with flashrom. Add a configure option for this feature that will disable the opcode for Write Status commands unless CONFIG_CHROMEOS is enabled. Tested to ensure that a default build without CONFIG_CHROMEOS has this option enabled while a build with CONFIG_CHROMEOS does not. Also ensured that when this option is disabled (for Chrome OS) then flashrom can be used with the --wp-enable and --wp-disable commands, depending on the state of the external write protect pin.

2017-07-25soc/intel/common/block: Modify fast_spi_lock_bar functionBarnali Sarkar
Use 16bit write to avoid touching the upper two bytes that may cause write cycle to fail in case a prior transaction has not completed. This function sets the WRSDIS(Bit 11) and FLOCKDN (Bit 15) of the SPIBAR + BIOS_HSFSTS_CTL. While WRSDIS is lockable with FLOCKDN, writing both in the same cycle is guaranteed to work by design. Avoid read->modify->write operation not to clear the RW1C bits unintentionally.

Earlier 15ms time-out was kept for SPI transactions which was not enough for SPI Erase transactions. Increase the max time-out time to 5 secs which was present in SKL before common code. This increase in time-out won't disturb other SPI transactions like Read, Write or Read Status, since, for those it will come out of the loop once FDONE bit or FCERR bit is set.

spi_crop_chunk is a property of the SPI controller since it depends upon the maximum transfer size that is supported by the controller. Also, it is possible to implement this within spi-generic layer by obtaining following parameters from the controller: 1. max_xfer_size: Maximum transfer size supported by the controller (Size of 0 indicates invalid size, and unlimited transfer size is indicated by UINT32_MAX.) 2. deduct_cmd_len: Whether cmd_len needs to be deducted from the max_xfer_size to determine max data size that can be transferred. (This is used by the amd boards.)
