| | | | | | | | | | | | | | | | | | | | | | | It's simply a bad idea to describe a macro in multiple locations. It'll make it hard to change. It'll be difficult to keep all locations in sync.

* Remove Makefile symlinks under board directoryDaisuke Nojiri2016-07-091-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | This feature is inconsistent. Not all boards have such a symlink (for a obvious reason). This feature is fragile. It's most likely not tested and going to be broken if not already. Developers won't like it if they have to test two different ways to build boards before submitting patches. This feature is not necessary. If you build EC in the standard way (e.g. make BOARD=samus), these symlinks are not needed. This feature is wasteful. Extra disk spaces are used and extra lines are added to Makefile (increasing code complexity slightly).

| | | | | | | | | | | | | | | | | | | | | | | | This DMA receiver uses a separate small circular buffer to DMA into.

* gpio: Refactor IRQ handler pointer out of gpio_listAseda Aboagye2015-04-101-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the gpio_info struct, we had a irq_handler pointer defined even though a majority of the GPIOs did not have irq handlers associated. By removing the irq_handler pointer out of the struct, we can save some space with some targets saving more than others. (For example, ~260 bytes for samus_pd). This change also brings about a new define: GPIO_INT(name, port, pin, flags, signal) And the existing GPIO macro has had the signal parameter removed since they were just NULL. GPIO(name, port, pin, flags) In each of the gpio.inc files, all the GPIOs with irq handlers must be defined at the top of the file. This is because their enum values from gpio_signal are used as the index to the gpio_irq_handlers table.

| | | | | | | | | | | | | | | | | | | | | | | | Originally, the ARM boards printed the keyboard scan matrix whenever it changed. This generated a lot of output, so we filtered that at the console channel level. When we refactored the keyboard scan module, that changed so that the scan matrix was not printed by default, and the 'ksstate' debug command was used to enable printing it. But on ARM boards, 'ksstate on' wouldn't do anything without ALSO using 'chan -1' to turn the keyboard console channel back on. And without the scan matrix printing by default, there's no reason to keep the keyboard channel off by default.
