Source at commit 48cc63a8540276d65746e82334550430da417b3f created 13 years 4 months ago. By Xiangfu Liu, some cleanup about xburst target - make zImage compile fine - set the ip addr to 192.168.254.101 - add more tty - format nand partition to 3 - cleanup keyboard - cleanup gmp940b driver - add color font patch, use setfont2 in userspace - add FPU in config, change font to 6x11 - add default CMDLINE, which is for zImage | |
