* SPI bitbanging: request/release busCarl-Daniel Hailfinger2010-09-151-9/+2
| | | | | | | | | | | | | | | | | | | | | | | | | SPI bitbanging on devices which speak SPI natively has a dual-use problem: We need to shut down normal SPI operations to do the bitbanging ourselves. Once we're done, it makes a lot of sense to reenable "normal" SPI operations again. Add request_bus/release_bus functions to struct bitbang_spi_master. Add a bitbang shutdown function (not used yet). Change MCP SPI and Intel NIC SPI to use the new request/release bus infrastructure. Cosmetic changes to a few error messages (80 column limit). There are multiple possible strategies for bus request/release: - Request at the start of a SPI command, release immediately afterwards. - Request at the start of a SPI multicommand, release once all commands of the multicommand are done. - Request on programmer init, release on shutdown. Each strategy has its own advantages. For now, we will stay with the first strategy which worked fine so far. Corresponding to flashrom svn r1171.

* Various cosmetic and coding-style fixesUwe Hermann2010-08-081-2/+2
| | | | | | | | | | | | | | | | | | | | | - Fix incorrect whitespace, indentation, and coding style in some places. - Drop '/**' Doxygen comments, we don't use Doxygen. Even if we would use it, the comments are useless as we don't have any Doxygen markup in there. - Use consistent vendor name spelling as per current website (NVIDIA, abit, GIGABYTE). - Use consistent / common format for "Suited for:" lines in board_enable.c. - Add some missing 'void's in functions taking no arguments. - Add missing fullstops in sentences, remove them from non-sentences (lists).
