Currently, kwboot only allows dynamic UART boot mode patching for SoCs with header version 0 (Orion, Kirkwood). This patch now enables this "-p" feature also for SoCs with header version 1 (Armada XP / 38x etc). With this its possible now to use the UART boot mode without on images that are generated for other boot devices, like SPI. So no need to change BOOT_FROM to "uart" for UART xmodem booting any more.
