The option CONFIG_VXWORKS_PREBOOT allows a board specific vxworks_preboot to be run just before jumping into the vxWorks images. This can be used to alter a register which is used differently by U-boot and vxWorks.

Where is vxworks_preboot defined ?
This patch should only give the basis for its use.
I use it in one of my Netstal boards MCU25. Patch will come soon, as I am cleaning them up at the moment. But the relevant snippet is here:
board/netstal/mcu25/mcu25.c
void vxworks_preboot(void) { if (sys_install_requested()) mtdcr(CPC0_CR1, CPCO_CR1_USE_EXTERNAL); }
Is this okay for you? Or do you have more questions?
Best regards
