uboot跑完之后，停在Starting kernel...
此时可以在kernel里把setup_early_printk()提前，用early_printk来调试。
prom_soc_init()函数会读取硬件信息，其中
cfg0 = __raw_readl(sysc + SYSC_REG_SYSTEM_CONFIG0);
dram_type = (cfg0 >> SYSCFG0_DRAM_TYPE_SHIFT) & SYSCFG0_DRAM_TYPE_MASK;
early_printk("cfg0 0x%x, dram_type %d\n", cfg0, dram_type);这里加了一句early_printk打印，发现dram_type值为3：
cfg0 0x132, dram_type 3 在代码中：
// mt7620.h
#define SYSCFG0_DRAM_TYPE_SDRAM 0
#define SYSCFG0_DRAM_TYPE_DDR1 1
#define SYSCFG0_DRAM_TYPE_DDR2 2
// mt7620.c
static __init void
mt7620_dram_init(struct ralink_soc_info *soc_info)
{
switch (dram_type) {
case SYSCFG0_DRAM_TYPE_SDRAM:
pr_info("Board has SDRAM\n");
soc_info->mem_size_min = MT7620_SDRAM_SIZE_MIN;
soc_info->mem_size_max = MT7620_SDRAM_SIZE_MAX;
break;
case SYSCFG0_DRAM_TYPE_DDR1:
pr_info("Board has DDR1\n");
soc_info->mem_size_min = MT7620_DDR1_SIZE_MIN;
soc_info->mem_size_max = MT7620_DDR1_SIZE_MAX;
break;
case SYSCFG0_DRAM_TYPE_DDR2:
pr_info("Board has DDR2\n");
soc_info->mem_size_min = MT7620_DDR2_SIZE_MIN;
soc_info->mem_size_max = MT7620_DDR2_SIZE_MAX;
break;
default:
BUG();
}
}dram_type=3, 就会走到BUG(). 所以在这里加上case 3。另外，在mt7620_get_dram_rate()取sdram频率的时候，也要加上3这个条件。
mt7620数据手册中只描述了0,1,2的值，也难怪内核代码里会这样写。不知道这里为什么会读出3来。
