lib: serial: fix RX path in litex-uart

2024-06-13T16:24:09Z

When used to read characters from the terminal (e.g., when the SBI console is used via ecall from linux with `console=hvc0`), we must acknowledge receipt of each character to "pop" it off the LiteUART hardware queue, and allow the next character to be made available.

2024-06-13T16:18:03Z

In DT, multiple reset devices may use the same driver, and they may have different priorities. If rc is returned after the first initialization, the highest priority device may be lost.

lib: utils/fdt: Fix DT property for APLIC delegation

2024-06-05T05:24:59Z

During Linux AIA driver review, the APLIC DT property for interrupt delegation was renamed to "riscv,delegation" so let's use the new DT property name and fallback to old DT property name if the new DT property name is not available.
