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",
}
}
