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.

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

Add 'volatile' qualifier to new CSR accessors
2020-02-21 21:08:22 +01:00
173117ad4b
Add 'volatile' qualifier to new CSR accessors
...
Through their use of the MMPTR() macro, the "classic"
csr_[read|write]simple() accsessors identify the MMIO
subregister with the 'volatile' qualifier.
Adjust the new, csr_[rd|wr]_uint[8|16|32|64]() accessors
to also utilize the 'volatile' qualifier. Since accesses
are implicit (a[i], where a is an 'unsigned long *'),
change 'a' to be a 'volatile unsigned long *' instead.
No difference was noticed in opcodes generated using the
gcc9 risc-v cross-compiler on x86_64 with standard LiteX
cflags (vexriscv and rocket were tested), but since
reports exist that 'volatile' matters on some combinations
of compilers and targets, add the 'volatile' qualifier just
to be on the safe side.
