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",
	}
}

liblitesdcard/sdcard: adjust card-ready timeout
2020-07-07 08:06:55 +02:00
Gabriel Somlo 6fdb36b84a liblitesdcard/sdcard: adjust card-ready timeout
Testing on nexys4ddr and rocket, approximately 12 iterations of the
timeout loop (using `busy_wait(1)`) are needed to receive a "ready"
response from the SDcard, assuming a "warm" reset where the card has
already been previously initialized.

If the SDcard is ejected and re-inserted, or if the board is "cold-reset"
(e.g., reprogrammed via openocd vs. a simple push of the reset button),
it takes approximately 450 iterations before the SDCard responds with a
"ready" message.

In either case, a timeout of 10 is insufficient. This patch increases
the busy-wait to 10, and the timeout loop counter to 128, which should
cover most cases.

Additionally, make a few minor cosmetic improvements.
