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.

2017-05-19drivers/spi/spi_flash: Clean up SPI flash probeFurquan Shaikh
1. Rename __spi_flash_probe to spi_flash_generic_probe and export it so that drivers can use it outside spi_flash.c. 2. Make southbridge intel spi driver use spi_flash_generic_probe if spi_is_multichip returns 0. 3. Add spi_flash_probe to spi_ctrlr structure to allow platforms to provide specialized probe functions. With this change, the specialized spi flash probe functions are now associated with a particular spi ctrlr structure and no longer disconnected from the spi controller.

2017-05-19drivers/spi/spi_flash: Pass in flash structure to fill in probeFurquan Shaikh
Instead of making all SPI drivers allocate space for a spi_flash structure and fill it in, udpate the API to allow callers to pass in a spi_flash structure that can be filled by the flash drivers as required. This also cleans up the interface so that the callers can maintain and free the space for spi_flash structure as required.

2017-05-05drivers/spi: Re-factor spi_crop_chunkFurquan Shaikh
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.)

2016-12-06spi_flash: Make a deep copy of spi_slave structureFurquan Shaikh
Commit 36b81af (spi: Pass pointer to spi_slave structure in spi_setup_slave) changes the way spi_setup_slave handles the spi_slave structure. Instead of expecting spi controller drivers to maintain spi_slave structure in CAR_GLOBAL/data section, caller is expected to manage the spi_slave structure. This requires that spi_flash drivers maintain spi_slave structure and flash probe function needs to make a copy of the passed in spi_slave structure. This change fixes the regression on Lenovo X230 and other mainboards.

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.
