2014-09-17spi: add Kconfig variable for dual-output read enableDavid Hendricks
Add a Kconfig variable so that driver code knows whether or not to use dual-output reads.

In theory this effectively doubles our throughput, though the initial results were almost negligibly better. Using a logic analyzer we see a pattern of 12 clocks, ~70ns delay, 4 clocks, ~310ns delay. So if we want to see further gains here then we'll probably need to tune AHB arbitration and utilization to eliminate bubbles/stalls when copying from APB DMA.

Get rid of the scalar arguments and make them part of intel_dp. Get rid of file-scope variables and use the ones in the intel_dp struct. In falco, use functions that peppy uses.

2014-09-08ARM: Generalize armv7 as arm.Gabe Black
There are ARM systems which are essentially heterogeneous multicores where some cores implement a different ARM architecture version than other cores. A specific example is the tegra124 which boots on an ARMv4 coprocessor while most code, including most of the firmware, runs on the main ARMv7 core. To support SOCs like this, the plan is to generalize the ARM architecture so that all versions are available, and an SOC/CPU can then select what architecture variant should be used for each component of the firmware; bootblock, romstage, and ramstage.

2014-08-25intel/gma: Clarify code and use dedicated init for Google PeppyRonald G. Minnich
Peppy had some issues with FUI. We decided it was time to create peppy-specific gma.c and i915io.c files. Using yabel and the i915tool, we generated a replay attack, then interpolated against the slippy i915io.c to get something working. Also, in preparation for moving code out of the mainboard gma.c to generic driver code, we got rid of some hardcodes in the mainboard gma.c that have no business being there. The worst were the computation of gmch_[m,n] and it turns out that we had some long-standing bugs related to confusion about 'bpp'. I've killed the word bpp everywhere I could because there are at least 3 things that correspond to bpp. We now have framebuffer, pipe, and panel bpp. The names are long because I want to avoid all the mistakes we've all been making in the last year :-) Sadly, that means a lot of changes not just peppy-related, but they are simple and in a good cause. The test pattern generation is driven by a global variable in mainboard/peppy/gma.c. I've found in the past that it's very useful to have a function like this available, as one can activate it while using a jtag debugger: halt at the right place in ramstage, set the variable to 1, continue. It's not enough code to worry about always including. The last hard-codes for M and N registers are gone, and the function to set from generic intel_dp.c code works. To avoid screen trash on a dev mode boot, which we liked but nobody else did :-), we now take the time to put a pleasing background color that sort of doubles as a power LED. Rough timing is ramstage start is at 2.2, and dev setup is done at 3.3. These new platforms are depressingly slow to boot. Rom init alone is taking 1.9 seconds. 13 years ago it was 3 seconds from power on to bash prompt. These CPUs are at least 10x faster and take much longer to get going. Future work, once we get this through, is to move more functions to the intel driver, and combine the mainboard i915io.c into the mainboard gma.c. That separation only existed because i915io.c was generated by a tool, and it had lots of ugliness. Most ugliness is gone.

2014-07-14SPI flash: Fix alignment checks in Page Program commandsKyösti Mälkki
There are two separate restrictions to take into account: Page Program command must not cross address boundaries defined by the flash part's page size. Total number of bytes for any command sent to flash part is restricted by the SPI controller capabilities. Consider CONTROLLER_PAGE_LIMIT=64, page_size=256, offset=62, len=4. This write would be split at offset 64 for no reason. Consider CONTROLLER_PAGE_LIMIT=40, page_size=256, offset=254, len=4. This write would not be split at page boundary as required. We do not really hit the second case. Nevertheless, CONTROLLER_PAGE_LIMIT is a misnomer for the maximum payload length supported by the SPI controller and is removed in a followup.

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.

2014-07-05drivers/spi: Reduce the per loop delay of spi_flash_cmd_poll_bit()Dave Frodin
At the end of some SPI operations the SPI device needs to be polled to determine if it is done with the operation. For SPI data writes the predicted time of that operation could be less than 10us. The current per loop delay of 500us is adding too much delay. This change replaces the delay(x) in the do-while loop with a timer so that the actual timeout value won't be lengthened by the delay of reading the SPI device.
