Yes, this is true if you are using the default SPI PRAM location.

MPC852T skips the microcode patch does it not?

For the case where you intentionally want to move SPI to elsewhere
(using ENET on SCC2), I will have to define CFG_SPI_DPMEM_OFFSET.
since CFG_SPI_DPMEM_OFFSET is not assigned to spi->rpbase for MPC852T
( microcode patch is skipped), SPI is not relocated using your patch.

In my case I tested relocating SPI to 0x1800.

You can try that on your MPC852T.
