2019-10-11[breaking-change] mercury: update leftover user_btn resources.whitequark
2019-10-03Reorganize resource taxonomy.whitequark
The current hierarchy isn't particularly well suited to resources like SDRAM or NOR flash, so make it much less fine-grained but easier to use and less nitpicky.
2019-10-03dev.display: factor out from dev.user. NFC.whitequark
2019-10-03[breaking-change] Factor out "display_7seg" resource.whitequark
With the expectation that "display_9seg", "display_14seg" and "display_16seg" will be forthcoming. There are no provisions in this resource itself for multiplexing the display. It is expected that on boards with multiplexed displays, an additional resource "display_7seg_ctrl" will be provided, and it would have either an n-bit signal "sel" (binary encoded) or an n-bit signal "en" (one-hot encoded). (This may be revisited in the future.) Fixes #17.
2019-09-23_blinky→test.blinkywhitequark
Expose blinky as a stable component, to make writing out-of-tree board files a bit nicer.
2019-09-23[breaking-change] Factor out "led", "button" and "switch" resources.whitequark
These resources were renamed as: * user_led → led * user_btn → button * user_sw → switch Fixes #13.
