Ilia Sergachev 8656ea9b67 interconnect/csr_bus: fix paged access warning 2020-07-20 18:23:09 +02:00
Jędrzej Boczar 07bc589c41 fix/Vivado: don't instantiate wishbone.Converter in add_adapter when not needed 
Fixes an issue with Vivado which crashes with SIGSEGV when building litex-buildenv at:
cc003bef3a
and litex bumped to 4a18b828bc,
with options:
    CPU=mor1kx; CPU_VARIANT=linux; PLATFORM=arty; FIRMWARE=linux; TARGET=net
The only difference in Verilog is that we avoid creating new Interface and doing
`new_interface.connect(interface)`, so this shouldn't make any difference, but
this somehow generates the error in Vivado (tested on v2018.3 and v2019.2).

Florent Kermarrec 4a18b828bc software/liblitesdcard/spisdcard: remove optimization on receive_block (not working on all configs) and increase max clk_freq to 20MHz. 2020-07-20 13:48:49 +02:00
Florent Kermarrec 100aa5a4ca soc/cores/spi/SPIMaster: rewrite/simplify. 
- Make sure MOSI is latched on start, MISO is stable during Xfer (last value).
- Allow clk_divider down to 2.
- improve test errors reporting with hex() on AssertEqual.

Not sure how they went missing...but just noticed them.

Florent Kermarrec ac35e158c1 bios/boot: add bootargs support on netboot/sdcardboot to optionally specify r1/r2/r3/addr. 
For example:
{
	"Image":  "0x40000000",
	"bootargs": {
		"r1":  "0x12345678",
	}
}

will copy Image to 0x40000000 and set r1 to 0x12345678.

By default, r1,r2,r3 are set to 0 and addr is the address if the last loaded image, so:

{
	"Image":         "0x40000000",
	"rootfs.cpio":   "0x40800000",
	"rv32.dtb":      "0x41000000",
	"emulator.bin":  "0x41100000",
}

is equivalent to:

{
	"Image":         "0x40000000",
	"rootfs.cpio":   "0x40800000",
	"rv32.dtb":      "0x41000000",
	"emulator.bin":  "0x41100000",
	"bootargs": {
		"r1":   "0x00000000",
		"r2":   "0x00000000",
		"r3":   "0x00000000",
		"addr": "0x00000000",
	}
}
