2019-04-01assert: Make dead_code() work at link-time instead of compile-timeJulius Werner
The dead_code() macro can be used to ensure that a certain code path is compile-time eliminated (e.g. if you want to make sure it's never executed for certain Kconfig combinations). Unfortunately, the current implementation via __attribute__((error)) hits only at the GCC level. This can catch code that can be compile-time eliminated based on state within the same file, but it cannot be used in cases where a certain library function is built but then garbage collected at link time. This patch improves the macro by relying solely on the linker finding an undefined reference. Unfortunately this makes the error message a little less expressive (can no longer pass a custom string), but it is still readable and one can add code comments next to the assertion to elaborate further if necessary Change-Id: I63399dc484e2150d8c027bc0256d9285e471f7cc Signed-off-by: Julius Werner <jwerner@chromium.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/32113 Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Furquan Shaikh <furquan@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>

There is merit in having new boards use the pinouts and controls in scarlet. This adds a config so new scarlet-derived boards can easily use scarlet structure without going through every file and adding new logic.

2017-11-06gru: Fix and export SPK_PA_EN GPIO for ScarletJulius Werner
On older Grus, GPIO0_A2 was an audio voltage rail enable line. On Scarlet, we instead moved the audio codec enable (previously on GPIO1_A2) there. Unfortunately the code still had some hardcoded leftovers that were overlooked in the initial port and make our speakers smell weird. This patch fixes the incorrect GPIO settings and adds the speaker enable pin to the GPIOs passed through the coreboot table, so that depthcharge doesn't have to keep its own definition of the pin which may go out of sync.

2017-09-06google/gru: Re-enable 3V rail GPIO on ScarletJulius Werner
We've decided to move control for the 3.0V rail (technically 3.3V on Scarlet, but who cares about millivolts) back to a GPIO on the AP for Scarlet rev2. This patch adds the necessary code to enable it and make ARM TF aware of its existence. Since the pin had previously not been connected to anything, we shouldn't really need to guard this by board ID... older Scarlets will just be twiddling an empty pin.

2017-07-19google/gru: Add support for Scarlet rev1Julius Werner
This patch adds the necessary changes to support Scarlet revision 1. Since the differences to revision 0 are so deep, we have decided not to continue support for it in the same image. Therefore, this patch will break Scarlet rev0. All the deviations from other Gru boards are currently guarded by CONFIG_BOARD_GOOGLE_SCARLET. This should be changed later if we introduce more variants based on the newer Scarlet board design.
