| | | | | | | | | | | | | | | | | | Add support for Samsung Flex-OneNAND devices. Flex-OneNAND combines SLC and MLC technologies into a single device. SLC area provides increased reliability and speed, suitable for storing code such as bootloader, kernel and root file system. MLC area provides high density and is suitable for storing user data. SLC and MLC regions can be configured through kernel parameter.

* mtd: uclinux: do not allow to be built as a moduleMike Frysinger2009-06-051-1/+1
| | | | | | | | | | | | | | | There isn't any benefit to building the uClinux MTD map as a module as the rootfs it requires in order to actually be usable is appended to the kernel image, not the module. No known system builds it this way either, so change the option to "bool".

* mtd: uclinux: allow systems to override map addr/sizeMike Frysinger2009-06-051-4/+6
| | | | | | | | | | | | | | | | Due to a processor anomaly (05000263 to be exact), most Blackfin parts cannot keep the embedded filesystem image directly after the kernel in RAM. Instead, the filesystem needs to be relocated to the end of memory. As such, we need to tweak the map addr/size during boot for Blackfin systems. This can be done in any early arch/board init code.

* mtd: plat_nand: allow platform to set partitionsH Hartley Sweeten2009-06-052-0/+5
| | | | | | | | | | | | | | | | | | | | | | | Add optional callback to allow platform to initialize partitions. Static partitions on a nand device could vary depending on the size of the device. This patch allows an optional platform callback to be used to setup this partition information at runtime. Scan order is: 1) chip.part_probe_types 2) chip.set_parts 3) chip.partitions 4) full mtd device (fallback for no partitions) Some of the existing nand drivers could possibly be replaced by the plat_nand driver by using this patch. These include autcpu12.c and ts7250.c drivers.

* mtd: remove pmcmsp-ramroot.cShane McDonald2009-06-053-114/+0
| | | | | | | | | | | | | | | The RAMROOT function was a successful but non-portable attempt to append the root filesystem to the end of the kernel image. The preferred and portable solution is to use an initramfs instead. The only user of this function was the msp71xx configuration in the MIPS architecture; as the use of the RAMROOT has been removed from that configuration, there are no more users, so this code can be removed.

| | | | | | | | | | | | | This patch adds (write|read)_buf callbacks to plat_nand. The NAND on the TS-7800 provisioned by the FPGA allows readw() and readl() to be used which gives a 2.5x speed up. To be able to use this from the plat_nand driver a hook for read_buf (and also write_buf whilst we are in there) need to be made available. This patch adds the hook.

Also fix the comment about picking the "best" ECC mode. We can't do those any more; that relied on knowing what kind of CPU we're using (they don't all support 4-bit ECC), and current policy is that drivers not have cpu_is_*() checks.

If the whole device is successfully erased, erase_chip() will return 0, and the code will fall through to the "else" clause, and do sector-by-sector erase in addition to the whole-chip erase. This patch corrects that. Also, the MAX_READY_WAIT_COUNT is insufficient for an m25p16 connected to a 400 MHz powerpc. Increasing it allows me to successfully program the device on my board.
