2020-11-16soc/amd/common/block: drop double underscores from include guardsFelix Held
Since coreboot is written in C and not C++, having the double underscores as a prefix is not an issue, but it also doesn't add much information, so drop them and the trailing ones as well.

2020-07-27soc/amd/common: Move spi access functions into their own fileMartin Roth
Because there was a lot of discussion about the size increase, I also looked at the impact of calling the get_spi_bar() function vs reading spi_base directly and just not worring about whether or not spi_base was already set. Using the spi_base variable directly is 77 bytes bytes for all 6 functions. it's roughly double the size to call the function at 153 bytes. This was almost entirely due to setting up a call stack. If we add an assert into each function to make sure that the spi_base variable is set, it doubles from the size of the function call to 333 bytes. For my money, the function call is the best bet, because it not only protects us from using spi_base before it's set, it also gets the value for us (at least on x86, on the PSP, it still just dies.)

2020-07-26soc/amd/common: Refactor and consolidate code for spi baseMartin Roth
Previously, the spi base address code was using a number of different functions in a way that didn't work for use on the PSP. This patch consolidates all of that to a single saved value that gets the LPC SPI base address by default on X86, and allows the PSP to set it to a different value. BUG=b:159811539 TEST=Build with following patch to set the SPI speed in psp_verstage.

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.
