Florent Kermarrec 0780b629a9 soc/cores/usb_fifo: cleanup and reduce fifo_depth (provide similar throughput when used as UART). 2020-06-23 16:51:24 +02:00
Florent Kermarrec 52b51e1e98 CHANGES: update. 2020-06-23 12:50:20 +02:00
Florent Kermarrec d59cec5acc software: use a single crt0 (deprecate crt0-ctr/crt0-xip) and avoid unnecessary defines. 
Since https://github.com/enjoy-digital/litex/issues/566, crt0-ctr and crt0-xip are now similiar
so we can get back to a single crt0 and remove the defines that were generated to distinguish
the different cases.

Since LiteX/MiSoC have diverged and are no longer compatible, we also no longer need to generate
the LiteX flag.

Benjamin Herrenschmidt 28ea4b3f4c software/microwatt: Fix copying data to RAM and clearing BSS 
This also makes us use the "small" memory model to avoid having to
use more complex constructs and adds the TOC to the linker script

Florent Kermarrec 5ddf350c2d software/spisdcard: reduce SPISDCARD_CLK_FREQ to 16MHz. 
25MHz does not seem to work on all boards/configurations, needs to be investigated.

Florent Kermarrec 653edd17ca bios/boot: simplify flashboot (remove specific linux boot). 
Storage in SPI Flash is generally limited and booting Linux from it is no longer very useful
since boot from SDCard is now supported. This is in the continuity of the SDCard/Ethernet
simplications to have an easier and more flexible boot scheme.

Florent Kermarrec f4abdd3f2c bios/boot: make Ethernet boot mode flexible (now also using boot.json similarly to SDCard boot). 
Example of boot.json:
{
	"Image":        "0x40000000",
	"rootfs.cpio":  "0x40800000",
	"rv32.dtb":     "0x41000000",
	"emulator.bin": "0x41100000"
}
 2020-06-11 13:12:58 +02:00
Florent Kermarrec c2ae22eeb6 bios/boot: make SDCard boot more flexible using a boot.json file on the SDCard. 
The BIOS now reads the boot.json file to know which files need to be copied to RAM and where.
It will fallback to boot.bin is no boot.json is found and boot will fail if neither is found.

Example of boot.json file used to boot Linux-On-LiteX-Vexriscv:
{
	"Image":        "0x40000000",
	"rootfs.cpio":  "0x40800000",
	"rv32.dtb":     "0x41000000",
	"emulator.bin": "0x41100000"
}
