2020-11-25	resources.interface: allow SPIResource to be unidirectional.	whitequark
	See #104.
2020-11-05	Factor out I2C resource.	awygle

2020-09-06	resources.memory: make cs pin optional for SDRAMResource	marble

2020-08-06	resources: allow use of ULPI PHYs with active-low RST pins	Katherine Temkin
	Also, fixes a typo that affected PHYs with rst specified
2020-07-19	Factor out direct USB and ULPI resources.	Kate Temkin

2020-07-16	[breaking-change] Update SPI pin names.	ECP5-PCIe
	The new names follow the OSHWA convention described at: https://www.oshwa.org/a-resolution-to-redefine-spi-signal-names/
2020-07-02	[breaking-change] resources.memory: add missing inversion on SRAMResource(dm=).	whitequark
	The semantics should be that a high bit of data mask (UB#LB#) enables the write to the corresponding byte.
2020-06-22	resources: allow UARTResource without control signals to have no role.	whitequark

2020-06-11	[breaking-change] resources: distinguish "dte"/"dce" roles of UART.	Ivan Grokhotkov
	UARTResource gets a new argument, "role", which determines flow control signal directions: - DCE means that the design acts as a modem - DTE means that the design acts as a PC
2020-03-14	resources.display: Apply inversion setting to dp	Stuart Olsen

2019-10-13	resources.memory: fix typo.	whitequark

2019-10-11	resources: add conn= argument to every factory.	whitequark

2019-10-03	Fix typo in SDCardResources().	whitequark

2019-10-03	Factor out "nor_flash" resource.	whitequark

2019-10-03	Factor out "sdram" resource.	whitequark

2019-10-03	[breaking-change] Fix polarity of "dm" signal in "memory" resource.	whitequark
	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".
2019-10-03	Reorganize 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.
