Subject: [PATCH 1/3] Improve riscv defconfigs
- Enable "sbi" command.
- Enable SBI based reset and poweroff commands.
- Set max supported CPUs on QEMU targets to 32.
- Enable relocation and use firmware FDT/DTB (i.e. generated by QEMU) for QEMU targets.

Subject: [PATCH 2/3] board: sifive: spl: Initialized the PWM setting in the
SPL stage
LEDs and multiple fans can be controlled by SPL. This patch ensures
that all fans have been enabled in the SPL stage. In addition, the
LED's color will be set to yellow.

Subject: [PATCH 3/3] board: sifive: spl: Set remote thermal of TMP451 to 85
deg C for the unmatched board
For TMP451 on the unmatched board, the default value of the remote
thermal threshold is 108 deg C. This commit initilizes it to 85 deg C at SPL.
