Florent Kermarrec 2538b2c300 soc/cores/clock: add with_reset parameter to create_clkout on iCE40PLL/ECP5PLL (similar to others PLLs).
Avoid instantiating the AsyncResetSynchronizer manually.

integration/soc: use csr.add() instead of add_csr()
add_csr() is defined by SoCCore, so won't work for any instances of
LiteXSoC that aren't also SoCCores. Also, use use_loc_if_exists=True
so SoCCore.csr_map can be used without double allocation errors.

Florent Kermarrec bda54b1177 software/liblitedram: reset ddrphy before initialization if rst CSR present (added on 7-series). 2020-08-28 17:59:24 +02:00
Florent Kermarrec b44ca6d61a soc/core/uart: add fixed burst support to UARTBone.
Allows speeding-up consecutives accesses on the same address. This is currently
used by LiteDRAM bench to speed-up the logging of the BIOS over the crossover UART,
but could be useful for other purposes.

Florent Kermarrec 1fb48d308e soc/cores/uart: add clock domain support to UARTBone.
In some cases, we want to run UARTBone in a specific clock domain. For example
in LiteDRAM bench, UARTBone is controlling the SoC and the main PLL generating
the  sys_clk is reconfigured dynamically, so we want to run UARTBone in a specific
(and fixed) clock domain.

Florent Kermarrec 587e09e3d6 software/liblitesdcard: increase sdcard_wait_cmd_done/sdcard_wait_data_done busy_wait.
Required after the command refactoring, will need to be adjusted.

Florent Kermarrec 4025257d8d software/liblitesdcard/sdcard: cleanup, update copyrights.
- improve indent.
- remove do/while in block functions (block's length/count only need to be configured once).
- update copyrights.

Florent Kermarrec 334635a97f software/liblitesdcard: remove wait for DMA Reader to complete, fix ifdef on SDCARD_CMD23_SUPPORT.
The FIFO after the DMA has been reduced and is no longer able to store an entire block, so the DMA will not complete
if write is not released.

Fix call to generation of minerva output file

verilog code, so -t/--type has to be specified explicitly.
