Adicionando suporte a M5282Lite no U-Boot

Consegui rodar o U-Boot 1.0.2 na placa M5282Lite, ela e’ praticamente igual a M8252EVB.

So precisei adicionar as definicoes nos arquivos abaixo para os valores aqui exibidos:

Em board/m5282evb/config.mk
TEXT_BASE = 0×10000

Em include/configs/M5282EVB.h
#define CFG_LOAD_ADDR 0×10000
#define CFG_MONITOR_BASE 0×10000

Depois disso e’ so compilar normalmente:
$ make M5282EVB_config
$ make

Usei o toolchain antigo (m68k-elf-tools-20030314), pois o mais novo estava gerando muitos erros. Quando compilava o executavel continha instrucoes invalidas.

Usei o dBug para carregar a imagem gerada (u-boot.bin):
