update firmware with Xboot on a micro through SPI bus and micro is slave..

[aventuri]

hello, i have some micro Xmega128A1U connected as slaves on a SPI bus to an Allwiinner SOC. i planned to use the SOC to update the firmware, so i was studying xboot. do you think the xboot could be used as a firmware update code for the micros? as far as i can see, there's no support for the SPI interface in the xboot code. is there a known issue or it's just because the use case was missing? i could eventually try to patch your code. do you think it's feasible easily?
