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

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.

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

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"
}
