É certo que este é um grande salto do kernel. 2.6 não tinha conceito de árvore de dispositivos e ainda não criei uma árvore de dispositivos para meu produto. Portanto, apenas os arquivos da árvore de dispositivos padrão com formas mais antigas de configurações UART nos arquivos da placa. Kernel surge sem UART, eu acho, porque nada acontece depois de "Iniciar Kernel ...".
Qualquer contribuição é muito apreciada. Obrigado
