2020-05-13soc/amd/common/block/spi: Include mmio.h in fch_spi_ctrl.cFurquan Shaikh
fch_spi_ctrl.c uses read*()/write*() functions which are declared in arch/mmio.h. This change includes the file arch/mmio.h in fch_spi_ctrl.c.

2020-05-12soc/amd/common/block/spi: Add support for common SPI configurationFurquan Shaikh
This change adds support for following SPI configuration functions to common block SPI driver and exposes them to be used by SoC: 1. fch_spi_early_init(): Sets up SPI ROM base, enables SPI ROM, enables prefetching, disables 4dw burst mode and sets SPI speed and mode. 2. fch_spi_config_modes(): This allows SoC to configure SPI speed and mode. It uses SPI settings from soc_amd_common_config to configure the speed and mode. These functions expect SoC to include soc_amd_common_config in SoC chip config and mainboard to configure these settings in device tree.

2020-03-18soc: Remove copyright noticesPatrick Georgi
They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

2020-01-03soc/amd/common/block/spi: remove code duplicationAaron Durbin
This removes all the duplicated code and logic and leverages the existing ones in libraries themselves. The current side effect is that protection cannot be fully enabled because the read, write, and write enable command are not exposed in struct spi_flash currently. That support can be revised if protection scheme makes sense for our use-cases once it's better understood.

2019-09-26soc/amd/common/block/spi/fch_spi_ctrl.c: Fix SPI vendor id codeRichard Spiegel
All solid state devices have vendor id defined by JEDEC specification JEP106, which originally allocated only 7 bits for it plus parity. When number of vendors exploded beyond 126, a banking proposition came maintaining compatibility with older vendors while allowing for 4 extra bits (16 banks) through the introduction of the concept "Continuation code", denoted by the byte value of 0x7f. Examples: 0xfe, 0x60, 0x18, 0x00, 0x00 => vendor 0xfe of bank o 0x7f, 0x7f, 0xfe, 0x60, 0x18 => vendor 0xfe of bank 2 BUG=b:141535133 TEST=Build and boot grunt.
