When enabling both SDHCI controllers, spl_mmc.c would actually choose device sdhci0 even if booted from sdhci1 (boot_device). This is because spl_mmc_get_device_index(boot_device) expects BOOT_DEVICE_MMC2[_2] in order to return index 1 instead of 0.
The #if defined(...) statement is copied from board/xilinx/zynqmp/zynqmp.c
So the key to properly enabling both controllers as boot sources is defining both CONFIG_ZYNQ_SDHCI0 and CONFIG_ZYNQ_SDHCI1 in your board's include/configs/*.h.
