s3c2410內(nèi)核的起始地址
* swapper_pg_dir is the virtual address of the initial page table.
本文引用地址:http://butianyuan.cn/article/201611/317275.htm* We place the page tables 16K below KERNEL_RAM_VADDR.Therefore, we must
* make sure that KERNEL_RAM_VADDR is correctly set.Currently, we expect
* the least significant 16 bits to be 0x8000, but we could probably
* relax this restriction to KERNEL_RAM_VADDR >= PAGE_OFFSET + 0x4000.
大致的意思是,在KERNEL_RAM_VADDR(內(nèi)核的在RAM中的地址)下面16K(16bit,也就是說(shuō)是32Kb,0x8000)的地方放著初始化頁(yè)表的虛擬地址,因此至少在RAM的起始地址還有偏移0x8000才能開(kāi)始放內(nèi)核。
