These patches are based on Marvell's bootloader for the AlleyCat5/5X which was based on u-boot 2018.03. I've split that code into consumable chunks and dropped as much unnecessary stuff as I can. I've also tried to sync the device trees as much as possible with the support that will land in Linux 6.0 although there are still some differences
Changes in v4: - Collect r-by from Stefan - Remove unused mvebu_get_nand_clock() (will return in a later series) - Remove unnecessary #ifdefs - Misc style cleanups - Replace CONFIG_MVEBU_SAR with simpler code implemented directly in soc.c based around get_sar_freq which the 32-bit platforms already use. - Move CONFIG_DISPLAY_BOARDINFO_LATE and CONFIG_ENV_OVERWRITE to the defconfig. - Remove CONFIG_BAUDRATE as this is already set in the default config - Remove CONFIG_USB_MAX_CONTROLLER_COUNT as this is not needed with DM_USB - Remove CONFIG_PREBOOT as we don't have anything to run - Remove commented out CONFIG_BOARD_EARLY_INIT_R - Remove DEBUG_UART configuration - Remove unnecessary console environment variable - Remove CONFIG_MVEBU_SAR
Changes in v3: - Remove unnecessary changes to RX descriptor handling - Use dev_get_dma_range() to parse dma-ranges property from parent device. - Remove unnecessary dma-ranges property from ethernet nodes (mvneta now correctly parses the property from the parent node). - Keep soc_print_clock_info and soc_print_device_info local to alleycat5. - Remove MMC and UBIFS distroboot options (MMC driver is not currently functional, NAND is not populated on the RD-AC5X board) - Remove unnecessary Ethernet configuration - Remove unnecessary NAND configuration - Remove memory node from dts so the value passed by the DDR FW will be used
Changes in v2: - Use distro boot by default - remove unnecessary SPI-NOR partitions
