Add Terasic DE0.

Factor out "nor_flash" resource.

Factor out "sdram" resource.
whitequark [Thu, 3 Oct 2019 06:10:43 +0000 (06:10 +0000)]
[breaking-change] Fix polarity of "dm" signal in "memory" resource.
LB# and UB# enable writing their corresponding byte. The "m" in "dm"
means mask; that is, logical high masks (prevents) the byte from
being written. This means that it should use Pins(), not PinsN(),
to get the behavior implied by "mask".
whitequark [Thu, 3 Oct 2019 05:54:12 +0000 (05:54 +0000)]
Reorganize resource taxonomy.
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.
whitequark [Thu, 3 Oct 2019 05:42:59 +0000 (05:42 +0000)]
Factor out "sd_card_{1bit,4bit,spi}" resources.
whitequark [Thu, 3 Oct 2019 03:02:44 +0000 (03:02 +0000)]
dev.display: factor out from dev.user. NFC.
whitequark [Thu, 3 Oct 2019 02:56:47 +0000 (02:56 +0000)]
[breaking-change] Factor out "display_7seg" resource.
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.

_blinky→test.blinky
Expose blinky as a stable component, to make writing out-of-tree
board files a bit nicer.
whitequark [Mon, 23 Sep 2019 08:07:37 +0000 (08:07 +0000)]
[breaking-change] Factor out "led", "button" and "switch" resources.
These resources were renamed as:
* user_led → led
* user_btn → button
* user_sw → switch
Fixes #13.
whitequark [Sat, 21 Sep 2019 14:30:14 +0000 (14:30 +0000)]
