Florent Kermarrec 4f935714de soc/doc: remove soc.get_csr_regions support.
Now that SoC documentation is integrated in LiteX, this is no longer needed.

Florent Kermarrec 68f565420d doc: remove partial doc imported from litex-buildenv-wiki: we'll create a LiteX wiki and doc. 2020-03-04 10:53:44 +01:00
Florent Kermarrec 0b923aa497 build: assume vendor tools are in the PATH and remove automatic sourcing, source and toolchain_path parameters.
Automatic sourcing was not consistent between build backends (and only really supported by ISE/Vivado)
and had no real additional value vs the complexity needed to support it. Now just assume required vendor
tools are in the PATH.

This also removes distutils dependency.

Florent Kermarrec c4fd6a7f2f targets/kc705: use DDRPHY_CMD_DELAY to center write leveling. 2020-02-27 13:00:35 +01:00
Florent Kermarrec 78a3223573 software/bios/sdram: allow setting CLK/CMD delay from user design and configure it before write/read leveling.
Setting a manual delay on CLK/CMD vs DQ/DQS is required on some configuration to center the write leveling window:

Before (delay = 0 taps):
Write leveling:
m0: |11000000000000011111111111| delay: 15
m1: |00000000000000111111111111| delay: 14
m2: |11110000000000000111111111| delay: 17
m3: |11110000000000000011111111| delay: 18
m4: |11111111110000000000000111| delay: 00
m5: |11111111110000000000000111| delay: 00
m6: |11111111111000000000000001| delay: 00
m7: |11111111111000000000000011| delay: 00

After (delay = 12 taps):
Write leveling:
m0: |11111111111111000000000000| delay: 00
m1: |11111111111100000000000001| delay: 00
m2: |00011111111111110000000000| delay: 03
m3: |00011111111111110000000000| delay: 03
m4: |00000000111111111111110000| delay: 08
m5: |00000000111111111111110000| delay: 08
m6: |00000000001111111111111000| delay: 10
m7: |00000000001111111111111000| delay: 10
