Florent Kermarrec eb64169521 build/lattice/diamond: remove ECP3 support. (ECP3 is not used and no longer interesting now that ECP5 has an open-source toolchain). 2020-03-24 19:36:57 +01:00

bunnie 5a402264d0 Fix off-by-one error on almost full condition for prefetch
This causes a DRC error on the Xilinx tools when the prefetch
lines setting is 1. Don't know why this wasn't caught earlier,
but it just popped up in CI.

Reclock spi sdcard access after initialisation
Depends upon https://github.com/enjoy-digital/litex/pull/435

After initialising the card, reclock the card, aiming for ~16MHz (divider is rounded up, as slower speed is safer), but a maximum of half of the processor speed.

Tested with the card being clocked to 12.5MHz on de10nano

Gabriel Somlo a33916bc6b software/libbase/spisdcard: fix 4-byte FAT fields on 64-bit CPUs
On 64-bit architectures (e.g., Rocket), 'unsigned long' means
eight (not four) bytes. Use 'unsigned int' wherever a FAT data
structure requires a four-byte field!

Piotr Esden-Tempski 279886721b Don't let python convert lane number to float.
While at it also:
* Don't multilane for reg >= 8 bit width.
* Only check if we should switch to multilane after finding min field width.

Gabriel Somlo b2103f4ad8 bios/sdcard: provide sdclk_set_clk() stub for clocker-less targets
Targets which lack an adjustable clocker will not expose the required
registers. Provide a stub sdclk_set_clk() routine for those situations.
