Masahiro Yamada a81b470883 mtd: denali: fix include guard and license block of denali.h
It looks like this header file is a concatenation of two headers.
Anyway, the include guard should be renamed and placed at the correct
postion and the license block in the middle should be deleted.

Huang Shijie e07caa3687 mtd: denali: kill the NAND_MAX_PAGESIZE/NAND_MAX_OOBSIZE
This patch kills the NAND_MAX_PAGESIZE/NAND_MAX_OOBSIZE by the following
way:
 1.) change the @buf field of nand_buf{} from an array to a pointer.
     also remove the DENALI_BUF_SIZE macro.

 2.) Before we call the nand_scan_ident, we allocate a temporary buffer
     whose size is PAGE_SIZE.

 3.) After we finish the nand_scan_ident, we have already getten the
     page size and oob size. We will allocate the right buffer size
     again.

Dinh Nguyen 30f9f2fb7b mtd: denali: add a DT driver
Add a device tree version of the Denali NAND driver. Based
on an original patch from Jamie Iles to add a MMIO version
of this driver.

Dinh Nguyen 2a0a288ec2 mtd: denali: split the generic driver and PCI layer
The Denali controller can also be found in SoC devices attached to a
simple bus.  Move the PCI specific parts into denali_pci so that we can
add a denali_dt that uses the same driver but for a device tree driver
instead of a PCI based device.

Jamie Iles c89eeda810 mtd: denali: detect the number of banks
Not all configurations of the Denali controller support 4 banks.  The
controller can support between 1 and 16 banks.  Detect this from the
design features register.

Jamie Iles 9589bf5bed mtd: denali: remove nearly-duplicated register definitions
The controller has interrupt enable/status register pairs for each bank
(along with ECC and status registers) that differ only in address offset.
Rather than providing definitions for each register, make the address a
macro so that it scales for devices with different numbers of banks.

Rather than using the PCI specific DMA API, convert to the generic
DMA API so that we can use the Denali NAND controller on other bus

Subject: [PATCH 1/4] mtd: denali: Remove device_info_tag structure.

Most of the variables in this structure are useless, so just
remove this structure and relevant codes.
