2015-04-13spi: support controllers with limited transfer size capabilitiesVadim Bendebury
Some SPI controllers (like Imgtec Pistachio), have a hard limit on SPI read and write transactions. Limiting transfer size in the wrapper allows to provide the API user with unlimited transfer size transactions. The tranfer size limitation is added to the spi_slave structure, which is set up by the controller driver. The value of zero in this field means 'unlimited transfer size'. It will work with existion drivers, as they all either keep structures in the bss segment, or initialize them to all zeros. This patch addresses the problem for reads only, as coreboot is not expected to require to write long chunks into SPI devices. BRANCH=none BUG=chrome-os-partner:32441, chrome-os-partner:31438 TEST=set transfer size limit to artificially low value (4K) and observed proper operation on both Pistachio and ipq8086: both Storm and Urara booted through romstage and ramstage.

2015-04-13elog: Fix regression that caused elog to omit "System boot" eventJulius Werner
CL:243671 moved the initialization of elog_initialized around, which is now unfortunately so late that the ELOG_TYPE_BOOT event gets omitted because the code believes the log to be broken at that time. Good thing we now have a FAFT test for these things that I had of course been too lazy to run. -.- The real reason for moving that line was to put it after any point in elog_init() that could still error out. The problem is that we might add the "cleared" event before we try to shrink (which can fail and cause an error)... but those two things cannot happen at the same time, so it should be okay to flip them around and mark the elog as initialized in between. BRANCH=none BUG=chrome-os-partner:35940 TEST=Ran firmware_EventLog on a Pinky, manually confirmed that I once again get "System boot" events.

2015-04-13elog: Correct behavior when FMAP section doesn't exist on ChromeOSJulius Werner
The elog driver has a really stupid bug that checks a result which is stored in an unsigned variable for < 0. Surprisingly GCC does not catch this nonsense right now, and I spent an hour trying out different warning options without finding one that doesn't also bring a load of stupid and unavoidable false positives (the biggest offender being -Wtype-limits, which does exactly what we'd want except for flagging things like if ((u8)var >= CONFIG_VAR_MIN) where the VAR_MIN Kconfig may or may not be 0). So, the only thing we can do is fix this one and wait for the next time something like that blows up. -.- Also change some more code to make the behavior more explicit (the old code already intended to work this way since flash_base is statically initialized to 0, never assigned in the error path and checked later in elog_init()... but there was an error message that incorrectly claimed a different fallback behavior, and explicitly assigning the values makes this easier to see). Finally, add another state to the elog_initialized variable to avoid trying to reinitialize a broken eventlog on every event (if it doesn't work the first time, chances are that it won't work later on during the same boot either). BRANCH=None BUG=chrome-os-partner:35940 TEST=Flashed Jerry with RO 6588.4 and RW 6588.23, observed how it now cleanly enters recovery mode without blowing its bootblock away with stray eventlog entries.

2015-04-10TPM: Reduce buffer size to fix stack overflowJulius Werner
The TPM driver by default allocates a 4K transfer buffer on the stack, which leads to lots of fun on boards with 2K or 3K stack sizes. On RK3288 this ends up writing over random memory sections which dependent on the memlayout of the day might contain timestamp data (no big deal) or page tables (-> bad time). This patch fixes the problem by reducing the buffer size to slightly above 1K, which still seems to work as far as I can tell. There was already some really odd code that #undef'ed this value and redefined it with the lower number in one .c file (unfortunately not the one with the buffer declaration), with no explanation whatsoever... I'm removing that and just assume the smaller value will be fine for everything. BRANCH=veyron BUG=None TEST=Booted Pinky and Falco.

2015-04-10tpm: Add ramstage driver and interrupt configurationDuncan Laurie
This adds a ramstage driver for the TPM and allows the interrupt to be configured in devicetree.cb. The interrupt vector is set like other PNP devices, and the interrupt polarity is set with a register configuration variable. These values are written into locality 0 TPM_INT_VECTOR and TPM_INT_ENABLE and then all interrupts are disabled so they are not used in firmware but can be enabled by the OS. It also adds an ACPI device for the TPM which will configure the reported interrupt based on what has been written into the TPM during ramstage. The _STA method returns enabled if CONFIG_LPC_TPM is enabled, and the _CRS method will only report an interrupt if one has been set in the TPM itself. The TPM memory address is added by the driver and declared in the ACPI code. In order to access it in ACPI a Kconfig entry is added for the default TPM TIS 1.2 base address. Note that IO address 0x2e is required to be declared in ACPI for the kernel driver to probe correctly. BUG=chrome-os-partner:33385 BRANCH=samus,auron TEST=manual testing on samus: 1) Add TPM device in devicetree.cb with configured interrupt and ensure that it is functional in the OS. 2) Test with active high and active low, edge triggered and level triggered setups. 3) Ensure that with no device added to devicetree.cb that the TPM is still functional in polling mode.

2015-03-18bootstate: use structure pointers for scheduling callbacksAaron Durbin
The GCC 4.9.2 update showed that the boot_state_init_entry structures were being padded and assumed to be aligned in to an increased size. The bootstate scheduler for static entries, boot_state_schedule_static_entries(), was then calculating the wrong values within the array. To fix this just use a pointer to the boot_state_init_entry structure that needs to be scheduled. In addition to the previous issue noted above, the .bs_init section was sitting in the read only portion of the image while the fields within it need to be writable. Also, the boot_state_schedule_static_entries() was using symbol comparison to terminate a loop which in C can lead the compiler to always evaluate the loop at least once since the language spec indicates no 2 symbols can be the same value.

This patch has a rather twisted history. It was originally split off from a chromium patch, which moved ALTCENTURY to Kconfig. However, since we have no user without ALTCENTURY, we've agreed that the best way to proceed is to eliminate the non-ALTCENTURY case entirely. The old commit message and identifiers are kept below for reference: The availability of "ALTCENTURY" is now set through a kconfig variable so it can be available to the RTC driver without having to have a specialized interface.

Coreboot has all necessary infrastructure to use the proper SPI flash interface in bootblock for CBFS. This patch creates a common CBFS wrapper which can be enabled on different platforms as required. COMMON_CBFS_SPI_WRAPPER, a new configuration option, enables the common CBFS interface and prevents default inclusion of all SPI chip drivers, only explicitly configured ones will be included when the new feature is enabled. Since the wrapper uses the same driver at all stages, enabling the new feature will also make it necessary to include the SPI chip drivers in bootblock and romstage images. init_default_cbfs_media() can now be common for different platforms, and as such is defined in the library.

2014-12-17spi_flash: Move (de-)assertion of /CS to single locationDavid Hendricks
This consolidates all calls to spi_claim_bus() and spi_release_bus() to a single location where spi_xfer() is called. This avoids confusing (and potentially redundant) calls that were being done throughout the generic spi_flash.c functions and chip-specific functions. I don't think the current approach could even work since many chip drivers assert /CS once and then issue multiple commands such as page program followed by reading the status register. I suspect the reason we didn't notice it on x86 is because the ICH/PCH handled each individual command correctly (spi_claim_bus() and spi_release_bus() are noops) in spite of the broken code.

Currently this boils down to x86 vs. non-x86. Yes, it's hideous. The current API only worked because, for better or worse, x86 platforms have been homogeneous in this regard since they started using SPI as an alternative to FWH for boot flash.

2014-12-16i2c: Replace the i2c API.Gabe Black
The new API is in use in depthcharge and is based around the "i2c_transfer" function instead of i2c_read and i2c_write. The new function takes an array of i2c_seg structures which represent each portion of the transfer after a start bit and before the stop bit. If there's more than one segment, they're seperated by repeated starts. Some wrapper functions have also been added which make certain common operations easy. These include reading or writing a byte from a register or reading or writing a blob of raw data. The i2c device drivers generally use these wrappers but can call the i2c_transfer function directly if the need something different. The tegra i2c driver was very similar to the one in depthcharge and was simple to convert. The Exynos 5250 and 5420 drivers were ported from depthcharge and replace the ones in coreboot. The Exynos 5420 driver was ported from the high speed portion of the one in coreboot and was straightforward to port back. The low speed portion and the Exynos 5250 drivers had been transplanted from U-Boot and were replaced with the depthcharge implementation. BUG=None TEST=Built and booted on nyan with and without EFS.

2014-12-09vboot: allow for non-memory-mapped VBOOT regionsAaron Durbin
Depending on the platform the underlying regions vboot requires may not be accessible through a memory-mapped interface. Allow for non-memory-mapped regions by providing a region request abstraction. There is then only a few touch points in the code to provide compile-time decision making no how to obtain a region. For the vblocks a temporary area is allocated from cbmem. They are then read from the SPI into the temporarily buffer. BUG=chrome-os-partner:27094 BRANCH=None TEST=Built and booted a rambi with vboot verification.

2014-11-23usbdebug: Fix migration to ramstageKyösti Mälkki
On entry to ramstage CBMEM is looked for a copy of an already initialized EHCI debug dongle state. If a copy is found, it contained the state before CAR migration and the USB protocol data toggle can be out of sync. It's an even/odd kind of a parity check, so roughly every other build would show the problem as invalid first line: 'ug found in CBMEM.' After CAR migration, re-direct the state changes to correct CBMEM table.
