2009-06-05mtd: uclinux: allow systems to override map addr/sizeMike Frysinger
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.

The DMAs have different bit sizes on BF52x and BF54x. From the PHRM: "The 16-bit DMA Access Bus (DAB) connects the DMA controller to the on-chip peripherals, PPI, SPI, Ethernet MAC, the SPORTs, NFC, HOSTDP and the UARTs." 32-bit DMA won't work for BF52x.

2009-06-05mtd: plat_nand: allow platform to set partitionsH Hartley Sweeten
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.

2009-06-05mtd: remove pmcmsp-ramroot.cShane McDonald
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.

2009-06-05mtd: extend plat_nand for (read|write)_bufAlexander Clouter
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.

This is limited to small-page flash for now; there are some page layout issues for large page chips. Note that most boards using this engine (like the DM355 EVM) include 2GiB large page chips.

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.
