Would you like to use the following code variant?

	if (slice)
		addr += ( prueth->pdata.banked_ms_ram
			? MSMC_RAM_BANK_SIZE
			: PRUETH_SW_TOTAL_BUF_SIZE_PER_SLICE);


Can the usage of the conditional operator be extended another bit
(also for the function “prueth_emac_buffer_setup” for example)?

Regards,
Markus
