2015-10-05Add EM100 'hyper term' spi console support in ramstage & smmMartin Roth
The EM100Pro allows the debug console to be sent over the SPI bus. This is not yet working in romstage due to the use of static variables in the SPI driver code. It is also not working on chipsets that have SPI write buffers of less than 10 characters due to the 9 byte command/header length specified by the EM100 protocol. While this currently works only with the EM100, it seems like it would be useful on any logic analyzer with SPI debug - just filter on command bytes of 0x11.

2015-03-20verstage should include the CBFS SPI wrapper, when configuredVadim Bendebury
Vboot2 targets so far did not have COMMON_CBFS_SPI_WRAPPER configuration option enabled, so the verstage is missing the relevant files in some Makefiles. This patch fixes the problem.

2014-12-30Provide a common CBFS wrapper for SPI storageVadim Bendebury
Coreboot has all necessary infrastructure to use the proper SPI flash interface in bootblock for CBFS. This patch creates a common CBFS wrapper which can be enabled on different platforms as required. COMMON_CBFS_SPI_WRAPPER, a new configuration option, enables the common CBFS interface and prevents default inclusion of all SPI chip drivers, only explicitly configured ones will be included when the new feature is enabled. Since the wrapper uses the same driver at all stages, enabling the new feature will also make it necessary to include the SPI chip drivers in bootblock and romstage images. init_default_cbfs_media() can now be common for different platforms, and as such is defined in the library. BUG=none TEST=manual . with this change and the rest of the patches coreboot on AP148 comes up all the way to attempting to boot the payload (reading earlier stages from the SPI flash along the way).

2014-03-12drivers/spi: Add support for adesto SPI flash partsChris Douglass
Adds support for the following Adesto Technologies SPI Flash parts. AT25DF081 AT25DF321 AT25DF641 It has been tested on an Orion VPX7654 board populated with an AT25DF321A part. The "08" and "64" densities have not been tested. These parts are the successors of the Atmel AT26DF line that was spun out or purchased by Adesto. In this patch, adesto.c is identical to winbond.c with part entries for the Adesto parts. The datasheet for the AT25DF parts includes a "100MHz" programming command in addition to the "85MHz" command that is currently used but this patch does not add support for that enhanced programming mode.
