2018-04-23soc{broadcom,imgtec,mediatek,qualcomm}: stop using spi_xfer_two_vectorsAaron Durbin
On a second look broadcom/cygnus and imgtec/pistachio appear to support full duplex. Therefore, remove the use of spi_xfer_two_vectors(). For mediatek/mt8173 and qualcomm/ipq40xx, the driver is written in such a way that it does not support full duplex. Remove the use of spi_xfer_two_vectors() and explicitly error out when a full duplex transaction is requested.

2018-02-21driver/uart: Introduce a way for mainboard to override the baudrateJulien Viard de Galbert
The rationale is to allow the mainboard to override the default baudrate for instance by sampling GPIOs at boot. A new configuration option is available for mainboards to select this behaviour. It will then have to define the function get_uart_baudrate to return the computed baudrate.

2017-08-14i2c: Move to Linux like `struct i2c_msg`Nico Huber
Our current struct for I2C segments `i2c_seg` was close to being compa- tible to the Linux version `i2c_msg`, close to being compatible to SMBus and close to being readable (e.g. what was `chip` supposed to mean?) but turned out to be hard to fix. Instead of extending it in a backwards compatible way (and not touching current controller drivers), replace it with a Linux source compatible `struct i2c_msg` and patch all the drivers and users with Coccinelle. The new `struct i2c_msg` should ease porting drivers from Linux and help to write SMBus compatible controller drivers. Beside integer type changes, the field `read` is replaced with a generic field `flags` and `chip` is renamed to `slave`. Patched with Coccinelle using the clumsy spatch below and some manual changes: * Nested struct initializers and one field access skipped by Coccinelle. * Removed assumption in the code that I2C_M_RD is 1. * In `i2c.h`, changed all occurences of `chip` to `slave`. @@ @@ -struct i2c_seg +struct i2c_msg @@ identifier msg; expression e; @@ ( struct i2c_msg msg = { - .read = 0, + .flags = 0, }; | struct i2c_msg msg = { - .read = 1, + .flags = I2C_M_RD, }; | struct i2c_msg msg = { - .chip = e, + .slave = e, }; ) @@ struct i2c_msg msg; statement S1, S2; @@ ( -if (msg.read) +if (msg.flags & I2C_M_RD) S1 else S2 | -if (msg.read) +if (msg.flags & I2C_M_RD) S1 ) @@ struct i2c_msg *msg; statement S1, S2; @@ ( -if (msg->read) +if (msg->flags & I2C_M_RD) S1 else S2 | -if (msg->read) +if (msg->flags & I2C_M_RD) S1 ) @@ struct i2c_msg msg; expression e; @@ ( -msg.read = 0; +msg.flags = 0; | -msg.read = 1; +msg.flags = I2C_M_RD; | -msg.read = e; +msg.flags = e ?

2017-06-13Consolidate reset API, add generic reset_prepare mechanismJulius Werner
There are many good reasons why we may want to run some sort of generic callback before we're executing a reset. Unfortunateley, that is really hard right now: code that wants to reset simply calls the hard_reset() function (or one of its ill-differentiated cousins) which is directly implemented by a myriad of different mainboards, northbridges, SoCs, etc. More recent x86 SoCs have tried to solve the problem in their own little corner of soc/intel/common, but it's really something that would benefit all of coreboot. This patch expands the concept onto all boards: hard_reset() and friends get implemented in a generic location where they can run hooks before calling the platform-specific implementation that is now called do_hard_reset(). The existing Intel reset_prepare() gets generalized as soc_reset_prepare() (and other hooks for arch, mainboard, etc. can now easily be added later if necessary). We will also use this central point to ensure all platforms flush their cache before reset, which is generally useful for all cases where we're trying to persist information in RAM across reboots (like the new persistent CBMEM console does). Also remove cpu_reset() completely since it's not used anywhere and doesn't seem very useful compared to the others.

2016-12-23spi: Get rid of SPI_ATOMIC_SEQUENCINGFurquan Shaikh
SPI_ATOMIC_SEQUENCING was added to accomodate spi flash controllers with the ability to perform tx and rx of flash command and response at the same time. Instead of introducing this notion at SPI flash driver layer, clean up the interface to SPI used by flash. Flash uses a command-response kind of communication. Thus, even though SPI is duplex, flash command needs to be sent out on SPI bus and then flash response should be received on the bus. Some specialized x86 flash controllers are capable of handling command and response in a single transaction. In order to support all the varied cases: 1. Add spi_xfer_vector that takes as input a vector of SPI operations and calls back into SPI controller driver to process these operations. 2. In order to accomodate flash command-response model, use two vectors while calling into spi_xfer_vector -- one with dout set to non-NULL(command) and other with din set to non-NULL(response). 3. For specialized SPI flash controllers combine two successive vectors if the transactions look like a command-response pair. 4. Provide helper functions for common cases like supporting only 2 vectors at a time, supporting n vectors at a time, default vector operation to cycle through all SPI op vectors one by one.

2016-11-22spi: Get rid of flash_programmer_probe in spi_slave structureFurquan Shaikh
flash_programmer_probe is a property of the spi flash driver and does not belong in the spi_slave structure. Thus, make spi_flash_programmer_probe a callback from the spi_flash_probe function. Logic still remains the same as before (order matters): 1. Try spi_flash_programmer_probe without force option 2. Try generic flash probing 3. Try spi_flash_programmer_probe with force option If none of the above steps work, fail probing. Flash controller is expected to honor force option to decide whether to perform specialized probing or to defer to generic probing.

2016-11-22spi: Clean up SPI flash driver interfaceFurquan Shaikh
RW flag was added to spi_slave structure to get around a requirement on some AMD flash controllers that need to group together all spi volatile operations (write/erase). This rw flag is not a property or attribute of the SPI slave or controller. Thus, instead of saving it in spi_slave structure, clean up the SPI flash driver interface. This allows chipsets/mainboards (that require volatile operations to be grouped) to indicate beginning and end of such grouped operations. New user APIs are added to allow users to perform probe, read, write, erase, volatile group begin and end operations. Callbacks defined in spi_flash structure are expected to be used only by the SPI flash driver. Any chipset that requires grouping of volatile operations can select the newly added Kconfig option SPI_FLASH_HAS_VOLATILE_GROUP and define callbacks for chipset_volatile_group_{begin,end}. spi_claim_bus/spi_release_bus calls have been removed from the SPI flash chip drivers which end up calling do_spi_flash_cmd since it already has required calls for claiming and releasing SPI bus before performing a read/write operation.

2016-07-26meditek/mt8173: dsi: set mipi pin driving control onJitao Shi
We set this driving control to prevent signal attenuation caused by LVDS DRV termination. When DA_LVDSTX_PWR_ON is not set, LVSH has no power and LVDS DRV termination status is unknown (floating). This creates a chance that MIPI output would be influenced. The DSI's LP signal will be half voltage attenuation. There will be no display on panel. When DA_LVDSTX_PWR_ON is set, LVSH and LVDS DRV termination are effective and termination is fixed OFF. The DSI won't be influenced. We only need to set this register once, so we set it here to prevent repeatedly setting in the kernel when the system goes to recovery mode.

2016-04-05google/oak: Log hardware watchdog in eventlogJulius Werner
The MT8173 hardware watchdog can assert an external signal which we use to reset the TPM on Oak. Therefore we do not need to do the same double-reset dance as on other Chromebooks to ensure that we reset in a correct state. Still, we have a situation where we need to reconfigure the watchdog early in the bootblock in a way that will clear information about the previous reboot from the status register, and we need that information later in ramstage to log the right event. Let's reuse the same watchdog tombstone mechanism from other boards, except that we don't perform a second reset and the tombstone is simply used to communicate between bootblock and ramstage within the same boot. BRANCH=None BUG=None TEST=Run 'mem w 0x10007004 0x8' on Oak, observe how it reboots and how 'mosys eventlog list' shows a hardware watchdog reboot event afterwards.
