2015-04-08ipq806x: Change all SoC headers to <soc/headername.h> systemJulius Werner
This patch aligns ipq806x to the new SoC header include scheme. Also alphabetized headers in affected files since we touch them anyway. BUG=None TEST=Tested with whole series. Compiled Storm.

2015-03-23ipq806x: implement GPIO APIVadim Bendebury
Add implementation of the GPIO API defined in src/include/gpiolib.h. Also, clean up the GPIO driver, make it use pointers instead of integers for register address. This requires a touch in the SPI driver, where the CS GPIO is toggled and in the board function where it enables USB interface. BUG=chrome-os-partner:30489 TEST=tested with the following patches, observed proto0 properly read the board ID.

2015-03-23Generalize revision number calculation functionVadim Bendebury
Some platforms use tertiary interpretation of GPIO input state to increase number of distinct values represented by a limited number of GPIOs. The three states are - external pull down (interpreted as 0) - external pull up (1) - not connected (2) This has been required by Nvidia devices so far, but Exynos and Ipq8086 platforms need this too. This patch moves the function reading the tertiary state into the library and exposes the necessary GPIO API functions in a new include file. The functions are still supposed to be provided by platform specific modules. The function interpreting the GPIO states has been modified to allow to interpret the state either as a true tertiary number or as a set two bit fields. Since linker garbage collection is not happening when building x86 targets, a new configuration option is being added to include the new module only when needed. BUG=chrome-os-partner:30489 TEST=verified that nyan_big still reports proper revision ID.

2014-12-30ipq8064: prepare include files before adding UART driverVadim Bendebury
These patch modifies .h files to match the coreboot API. A few more significant changes are: - UART specific fields removed from common board structure in cdp.h. These fields are set at compile time in u-boot (where this structure comes from), they will be set in a different structure in the UART driver in an upcoming patch. - an inline wrapper is added in gpio.h to provide GPIO API the UART driver expects. - the ipq_configure_gpio() is passed the descriptor placed in ro data.
