ca6189db48 Refactor OneNAND IPL code
Refactoring the OneNAND IPL code

and some minor fixed:
- Remove unnecessary header file
- Fix wrong access at read interrupt
- The recent OneNAND has 4KiB pagesize

Also Board can override OneNAND IPL image

69bcabb516 Fix OneNAND ipl to read CONFIG_SYS_MONITOR_LEN
Currently OneNAND initial program loader (ipl) reads only block 0 ie 128KB.
However, u-boot image for apollon board is 195KB making the board
unbootable with OneNAND.

Fix ipl to read CONFIG_SYS_MONITOR_LEN.
CONFIG_SYS_MONITOR_LEN macro holds the U-Boot image size.

196c74311f Reduce OneNAND IPL common code
OneNAND IPL has common codes for RAM init, load data, and jump to 2nd
bootloader, but it's common code used about 300~400 bytes. So board
specific codes, such as lowlevel_init, can't has enough code. It make
a difficult to implement OneNAND IPL.

his patch make this common code as small as possible. and give
lowlevel_init can have more codes.

1bb707c39a Add Flex-OneNAND booting support
Flex-OneNAND is a monolithic integrated circuit with a NAND Flash array
using a NOR Flash interface. This on-chip integration enables system designers
to reduce external system logic and use high-density NAND Flash
in applications that would otherwise have to use more NOR components.

Flex-OneNAND enables users to configure to partition it into SLC and MLC areas
in more flexible way. While MLC area of Flex-OneNAND can be used to store data
that require low reliability and high density, SLC area of Flex-OneNAND
to store data that need high reliability and high performance. Flex-OneNAND
can let users take advantage of storing these two different types of data
into one chip, which is making Flex-OneNAND more cost- and space-effective.

751b9b5189 OneNAND Initial Program Loader (IPL) support
This patch enables the OneNAND boot within U-Boot.
Before this work, we used another OneNAND IPL called X-Loader based
on open source. With this work, we can build the oneboot.bin image
without other program.

The build sequence is simple.
First, it compiles the u-boot.bin
Second, it compiles OneNAND IPL
Finally, it becomes the oneboot.bin from OneNAND IPL and u-boot.bin
The mechanism is similar with NAND boot except it boots from itself.

Another thing is that you can only use the OneNAND IPL only to work
other bootloader such as RedBoot and so on.
