This patch is intended to update the current configuration implementation of HiFive Unleashed board so that it is as per the guidelines provided in U-boot's doc/README.kconfig. The board has a FU540-C000 SoC built around U54-MC Core complex.
This patch is based on the commit 75551c8bfc95 ("Merge branch '2019-07-26-ti-imports'") in master branch of repo[1] and is tested with OpenSBI to use the dtb passed as argument in FW_PAYLOAD_FDT_PATH from the mainline kernel and boot's linux image over tftp. The patch is available for testing at dev/sagark/sifive_u540defconfig branch here [2].

Summary: -Update TARGET in board select menu. -Update SYS_CPU from generic to u54-mc. -Added SYS_SOC. -Update SYS_BOARD from fu540 to hifive_unleashed. -Update SYS_CONFIG_NAME from sifive-u540 to hifive_unleashed . -Update MAINTAINERS file with relevant entries corresponding to the above changes.
This patch will conflict with few patches which are already submitted for review, it would be good if U-boot folks would suggest something accordingly.
