Modified flashboot() to skip copy to main ram if there is no main ram, and instead execute in place out of SPI flash. (For this to work the linker .ld will also need to redirect references to be inside the SPI flash mapping.)

Isn't it a duplicate of #55? |

@enjoy-digital - @rohitk-singh Is testing this change on the cmod-a7 |

ok, we'll merge it once validated. |
|
@rohitk-singh: Was it validated? |
|
@enjoy-digital No. We ran issues with Cmod A7 and were not able to program it. Most likely issues with Openocd and the 12MHz clock sourced from FTDI, which openocd controls. I'll test it with MimasV2 and then confirm. Please do not merge yet. |

@rohitk-singh: any update? |
|
@enjoy-digital Sorry for delay. I just tested it. Works fine. Designer just has to make sure to define |
