2014-07-14SPI: Split writes using spi_crop_chunk()Kyösti Mälkki
SPI controllers in Intel and AMD bridges have a slightly different restriction on how long transactions they can handle.

2014-07-05spi: Change spi_xfer to work in units of bytes instead of bits.Gabe Black
Whenever spi_xfer is called and whenver it's implemented, the natural unit for the amount of data being transfered is bytes. The API expected things to be expressed in bits, however, which led to a lot of multiplying and dividing by eight, and checkes to make sure things were multiples of eight. All of that can now be removed. BUG=None TEST=Built and booted on link, falco, peach_pit and nyan and looked for SPI errors in the firmware log. Built for rambi.

2014-07-05spi: Remove unused parameters from spi_flash_probe and setup_spi_slave.Gabe Black
The spi_flash_probe and and spi_setup_slave functions each took a max_hz parameter and a spi_mode parameter which were never used. BUG=None TEST=Built for link, falco, rambi, nyan.

2014-05-29fsp_baytrail: Add the FSP version of Intel's Bay Trail-I chipMartin Roth
While similar to the Bay Trail-M/D code based on the MRC, there are many differences as well: - Obviously, uses the FSP instead of the MRC binaries. - FSP does additional hardware setup, so coreboot doesn't need to. - Different microcode & microcode loading method - Uses the cache_as_ram.inc from the FSP Driver - Various other changes in support of the FSP Additional changes that don't have to to with the FSP vs MRC: - Updated IRQ Routing - Different FADT implementation. This was validated with FSP: BAYTRAIL_FSP_GOLD_002_10-JANUARY-2014.fd SHA256: d29eefbb33454bd5314bfaa38fb055d592a757de7b348ed7096cd8c2d65908a5 MD5: 9360cd915f0d3e4116bbc782233d7b91 Change-Id: Iadadf8cd6cf444ba840e0f76d3aed7825cd7aee4 Signed-off-by: Martin Roth <gaumless@gmail.com> Signed-off-by: Martin Roth <martin.roth@se-eng.com> Reviewed-on: http://review.coreboot.org/5791 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
