Porting a BSP from 4.10 to 5

I have a platform which has Marvell 64360 + PowerPC IBM750FX onboard.
Sources and binaries of RTEMS 4.10 + custom BSP came with the device. I
would know if there is a sort of "porting guide" for BSPs, in order to do
the least number of modifications needed to use that BSP on RTEMS 5.
Alternatively, I'd like to know if there is mainline support in RTEMS5 for
such a platform (commercially known as ESD-CPCI750, optionally available
with an ESD-CPCI-ASIO4 serial port expansion).

I already built my applications and deployed RTEMS 5 on other platforms,
like the BeagleBone Black, but I'm certainly not a kernel developer, so I'd
like to know from anyone how much effort is required to do a working port,
or what I should look at initially in order to at least make it compatible
from a build system perspective (I noticed some differences) in order to
start playing with it and maybe fix compilation errors and stuff like this

Thank you in advance,
