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.

2019-02-20drivers/spi/spi_flash.c: Avoid static scan false positiveRichard Spiegel
Static scan-build indicates a possible invalid return from function spi_flash_cmd_erase(). The root cause is because the scan believes it's possible for offset to be above the end address in the first pass, thus not setting a value for variable ret. Assign initial value of -1 to variable ret to make checker happy.

2018-04-23drivers/spi: reduce confusion in the APIAaron Durbin
Julius brought up confusion about the current spi api in [1]. In order alleviate the confusion stemming from supporting x86 spi flash controllers: - Remove spi_xfer_two_vectors() which was fusing transactions to accomodate the limitations of the spi controllers themselves. - Add spi_flash_vector_helper() for the x86 spi flash controllers to utilize in validating driver/controller current assumptions. - Remove the xfer() callback in the x86 spi flash drivers which will trigger an error as these controllers can't support the api.

2018-04-03spi: Add helper functions for bit-bangingJulius Werner
Sometimes when bringing up a new board it can take a while until you have all the peripheral drivers ready. For those cases it is nice to be able to bitbang certain protocols so that you can already get further in the boot flow while those drivers are still being worked on. We already have this support for I2C, but it would be nice to have something for SPI as well, since without SPI you're not going to boot very far. This patch adds a couple of helper functions that platforms can use to implement bit-banging SPI with minimal effort. It also adds a proof of concept implementation using the RK3399.

2018-01-30drivers/spi: support cmd opcode deduction for spi_crop_chunk()Aaron Durbin
spi_crop_chunk() currently supports deducting the command length when determining maximum payload size in a transaction. Add support for deducting just the opcode part of the command by replacing deduct_cmd_len field to generic flags field. The two enums supported drive the logic within spi_crop_chunk(): SPI_CNTRLR_DEDUCT_CMD_LEN SPI_CNTRLR_DEDUCT_OPCODE_LEN All existing users of deduct_cmd_len were converted to using the flags field.

2018-01-26drivers/spi/spi_flash: honor spi controller fifo size for readsAaron Durbin
The spi_flash_cmd_read_fast() and spi_flash_cmd_read_slow() were just passing full size buffers to the spi controller ops. However, the code wasn't honoring what the spi controller can actually perform. This would cause failures to read on controllers when large requests were sent in. Fix this by introducing a spi_flash_cmd_read_array_wrapped() function that calls spi_flash_cmd_read_array() in a loop once the maximum transfer size is calculated based on the spi controller's settings.
