am335x_spi_partitions在什么地方!

sdk 8.0下面的分区文件在什么地方啊,一直都找不到!
/* SPI 0/1 Platform Data */
/* SPI flash information */
staticstructmtd_partition am335x_spi_partitions[] = {
    /* All the partition sizes are listed in terms of erase size */
    {
        .name       ="SPL",
        .offset     = 0,           /* Offset = 0x0 */
        .size       = SZ_128K,
    },
    {
        .name       ="U-Boot",
        .offset     = MTDPART_OFS_APPEND,  /* Offset = 0x20000 */
        .size       = 2 * SZ_128K,
    },
    {
        .name       ="U-Boot Env",
        .offset     = MTDPART_OFS_APPEND,  /* Offset = 0x60000 */
        .size       = 2 * SZ_4K,
    },
    {
        .name       ="Kernel",
        .offset     = MTDPART_OFS_APPEND,  /* Offset = 0x62000 */
        .size       = 28 * SZ_128K,
    },
    {
        .name       ="File System",
        .offset     = MTDPART_OFS_APPEND,  /* Offset = 0x3E2000 */
        .size       = MTDPART_SIZ_FULL,    /* size ~= 4.1 MiB */
    }
};
Gary Wu:

在SDK06.00(kernel为3.2及之前)及以前的版本,通常你会在Linux/arch/arm/mach-omap2/board-am335xevm.c中找到;

而在SDK07.00(kernel为3.12)和SDK08.00(kernel 为3.14) ,由于linux源码中没有对应的板级文件,板级配置通过devicetree进行。

所以你可以参考am335x-evm.dts里面的nand flash的分区,添加SPI的分区。

回复 Gary Wu:

非常感谢,我看到board-am335xevm.c中,有下面这段:

/* MTD partition table */ /* All SPL-* partitions are sized to minimal length * which can be independently programmable. For * NAND flash this is equal to size of erase-block */

是不是下面的nand分区不用改就可以用作spi分区啊,刚接触TI,很多不懂,如果不是的,能否提供一下spi分区的例子啊,跪求!

#address-cells = <1>; #size-cells = <1>; partition@0 { label = "NAND.SPL"; reg = <0x00000000 0x000020000>; }; partition@1 { label = "NAND.SPL.backup1"; reg = <0x00020000 0x00020000>; }; partition@2 { label = "NAND.SPL.backup2"; reg = <0x00040000 0x00020000>; }; partition@3 { label = "NAND.SPL.backup3"; reg = <0x00060000 0x00020000>; }; partition@4 { label = "NAND.u-boot-spl-os"; reg = <0x00080000 0x00040000>; }; partition@5 { label = "NAND.u-boot"; reg = <0x000C0000 0x00100000>; }; partition@6 { label = "NAND.u-boot-env"; reg = <0x001C0000 0x00020000>; }; partition@7 { label = "NAND.u-boot-env.backup1"; reg = <0x001E0000 0x00020000>; }; partition@8 { label = "NAND.kernel"; reg = <0x00200000 0x00800000>; }; partition@9 { label = "NAND.file-system"; reg = <0x00A00000 0x0F600000>; };
