2017-01-13fsp_baytrail: Enable graphic init per defaultWerner Zeh
Baytrail SoC has a bug where in some cases the DisplayPort can hang leading to a non-working display (it just stays black). To avoid this hang, a patch was introduced in 02/2016 (1c3b1112fa - fsp_baytrail: Fix a possible hanging DisplayPort) but per default not switched on so that each mainboard can decide if it wants to use this patch or not. Recently a new case of this bug was reported by Benoit Sansoni (benoit.sansoni@kontron.com) and he requested to enable this fix per default as it costs him a lot of time to find the cause and even the already available fix in coreboot. To avoid this effort for someone else in the future we can enable this fix per default as no negative side effects are known and it is now tested at Siemens and at Kontron on different mainboards with success. As the goal is to enable this code permanently the config switch is not longer needed and is removed.

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: 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.

Change the address mask from 0xffff to 0x3ff and remove the subtraction of the constant value 0xf020 in order to print only the register offset within the SPI controller and avoid the visibility of any fragments from SPI base address. 3.

A call to i2c_read() for a non-existent address followed by an i2c_read() to a valid address results in a false abort status for the 2nd call. i2c_read(1, 0x40, 0, buf, sizeof(buf)) => 0x2000000 (I2C_ERR_TIMEOUT) i2c_read(1, 0x74, 0, buf, sizeof(buf)) => 0x4000000 (I2C_ERR_ABORT) Because the abort status register is cleared on read and wait_tx_fifo() reads it twice, the returned status does not contain the abort status. Fixing that changed the 2nd read to reflect the abort status. i2c_read(1, 0x40, 0, buf, sizeof(buf)) => 0x2000000 (I2C_ERR_TIMEOUT) i2c_read(1, 0x74, 0, buf, sizeof(buf)) => 0x4000001 (I2C_ERR_ABORT) Bit 0 indicates that the address was not acknowledged by any slave. That's the abort status from the previous transaction. So I added a read of the abort status before starting a transaction in both i2c_read() and i2c_write(). i2c_read(1, 0x40, 0, buf, sizeof(buf)) => 0x2000000 (I2C_ERR_TIMEOUT) i2c_read(1, 0x74, 0, buf, sizeof(buf)) => 0 (I2C_SUCCESS) Tested on a Bay Trail E3845 SoC.

2016-02-25fsp_baytrail: Fix a possible hanging DisplayPortWerner Zeh
On some devices it can happen that DisplayPort TX lanes do not work properly if the power gate setup is omitted. If that happens, DisplayPort training will fail and therefore DisplayPort channel will not work. Both ports are affected. It seems that not every CPU shows this effect and those that are affected tend to fail more often in a cold environment. With this fix a board that originally shows this failure was running for over 1000 power cycles without issues.

2016-02-22fsp_baytrail: Add full support for iosf access in reg_scriptWerner Zeh
Add all needed functions to fsp_baytrail so that reg_script can do full iosf access. To keep it simple, this patch synchronises iosf access between baytrail and fsp_baytrail.

2016-01-08fsp_baytrail: Add additional PCI space above 4GBMartin Roth
This just tells the OS that it can use the 16GB of address space at the 48GB mark for PCI. This is the upper 16GB of Bay Trail's 36 bit physical address space. This could be hardcoded into the UMEM definition, but doing it this way makes it more plain what it's doing, and allows for modification to put it just above the top of upper memory, similar to what is done with the standard PCI region above the top of low memory.

Baytrail has I2c Busses 0 to 6, so is supposed to error out if the I2c driver is called with 7 or greater. Due to an off-by-one error it could be called with bus 7.

2015-12-16intel/fsp_baytrail: Fix PCI_DEV_PIRQ_ROUTE macro endingBen Gardner
The macro PCI_DEV_PIRQ_ROUTE ends with a comma and escaped newline. Ending a macro with an escaped newline is always wrong. The final comma is not necessary, as all uses of PCI_DEV_PIRQ_ROUTE() properly separate calls with a comma. I haven't investigated whether this is causing a real issue, but it should be leaving gaps in struct baytrail_irq_route.pcidev. The non-FSP baytrail does not have this issue.
