Key features: - 4 cores per cluster, 2 clusters on chip - UART IP is Intel XScale UART Some key considerations: - ISA string is inferred from vendor documentation[2] - Cluster topology is inferred from datasheet[1] and L2 in vendor dts[3] - No coherent DMA on this board Inferred by taking vendor ethernet and MMC drivers to the mainline kernel. Without dma-noncoherent in soc node, the driver fails. - Add cache nodes K1 SoC has 128 sets of 32KiB L1 I/D Cache for each hart, and 512 sets of 512KiB L2 Cache for each cluster. Currently only support booting into console with only uart, other features will be added soon later.
