Hello all,
I have a flash memory in a custom device and I'd like to place a standard
filesystem on it, so I guess there must be a way
to tell the kernel to use it.
Here's the DTS definition:
Flash_Serie: gpio@81460000 {
compatible = "xlnx,xps-gpio-2.00.a",
"xlnx,xps-gpio-1.00.a";
reg = < 0x81460000 0x10000 >;
xlnx,all-inputs = <0x0>;
xlnx,all-inputs-2 = <0x0>;
xlnx,dout-default = <0x0>;
xlnx,dout-default-2 = <0x0>;
xlnx,family = "virtex4";
xlnx,gpio-width = <0xa>;
xlnx,gpio2-width = <0x20>;
xlnx,interrupt-present = <0x1>;
xlnx,is-dual = <0x0>;
xlnx,tri-default = <0xffffffff>;
xlnx,tri-default-2 = <0xffffffff>;
} ;
The bits are addressed as such:
// Flash memory control
#define FLASH_SCK (1<<4) // Serial Clock
#define FLASH_SI (1<<3) // Data Out _to_ the flash (DO)
#define FLASH_RSTN (1<<2) // Reset
#define FLASH_WPN (1<<1) // Write Protect
#define FLASH_SO (1<<0) // Data In _from_ the flash (DI)
So how can I tell the kernel that there's a FAT32 or ext2 filesystem on it
(note, I don't need it as a root/boot
filesystem) ?
Thanks.
