The S3Cxxxx family consists of ARMv4, ARMv5 and ARMv6 types of CPU cores. The
S3C24xx sub family is only one of it. To be able to handle all CPUs in one mach
directory, use a more generic name for it.

OpenRISC is the original flagship project of the OpenCores community.
This project aims to develop a series of general purpose open source
RISC CPU architectures.
A team from OpenCores provided the first implementation, the OpenRISC
1200, written in the Verilog hardware description language.
Even though I should have created an mach-or1200 directory, it is not
necessary for now. The OpenRISC 1200 CPU is the only one available and
it will be for some time.

The flags in struct console_device have to be initialized
to zero. Otherwise the following can happen:
- console_register sets the initial baudrate of a new console
before we set the global console init state to CONSOLE_INIT_FULL.
- In console_baudrate_set we test whether the current console is
active which may be true because of unitialized flags.
- we then call getc() to wait for the user to accept the new settings
and we are stuck because of the CONSOLE_UNINITIALIZED state
we will never get anything from getc().
Looking back this explains some cases for me when barebox refused
to start and I really wonder why this did not become a more visible
problem before.

NAND, into mtd->writesize which is MTD generic.

nand devices still appear as nand<N>.
