The driver is taken from the Linux kernel, with the following changes :
- all DMA removed
- all asynchronous handling removed, including the interrupt handler,
and the asynchronous state handling
- pxa armada support removed
Most the kernel structure was kept, to ease up future fixes integration
from the kernel driver.
The driver is tested on a pxa3xx system development
board (aka. zylonite), and reading, writing, erasing, and bad block
management were tested.

In the request packet, we are supposed to copy the IP that the DHCP server
provided in the offer packet so that dhcp_extended can fill the option 50.
There is actually an error in barebox as the pointer to the packet currently
built is used as the source instead of the pointer to the offer packet.
With this patch, barebox now sends a request packet which includes the right
requested IP in option 50.

Instead of introducing new functions each time a new power supply
situation is to be added, this patch adds parameters to mx28_power_init.
Right now there are three parameters:
- has_battery - true when this board has a battery.
- use_battery_input - true when this board is supplied from the
battery input, but has a DC source instead of a real battery
- use_5v_input - true when this board can use the 5V input
The third one is introduced with this patch and allow to boot a board from 5v
(USB) source only. The main necessary change this needs is that the DC-DC
converter must always be sourced from DCDC_4P2 (DROPOUT_CTRL field of
HW_POWER_DCDC4P2)

This adds device tree support for the stm serial driver. This
driver really is a AMBA primecell, so the amba-pl011 could be
used. However, the current code tries to get the apb_pclk before
the clocks are registered, so this does not work. Use the stm
driver instead until a solution is found.

Since include/linux/linkage.h includes <asm/linkage.h>, the basic
coding style we should follow is:
- <linux/linkage.h> should contain default macro defines
- <asm/linkage.h> can define arch-specific macros and override the
default ones in <linux/linkage.h>
The arch/blackfin/include/asm/linkage.h has redundant defines that
are already defined in <linux/linkage.h>.
Replace it with the one imported from Linux 3.19-rc6.
Generally, <asm/linkage.h> should not be included directly.
Fix two files to include <linux/linkage.h> instead.

Calculating the size and end of the test region as
end = PAGE_ALIGN_DOWN(bank->res->end) - 1;
size = end - start + 1;
is wrong. For an example resource of
start = 0x80000000, end = 0x8fffffff
end results in:
end = PAGE_ALIGN_DOWN(0x8fffffff) - 1 = 0x8fffefff
instead of 0x8fffffff. The size is then calculated to
size = end - start + 1 = 0x8fffefff - 0x80000000 + 1 = 0x0ffff000
instead of 0x10000000
The correct way to do this is to calculate the real size and apply a
PAGE_ALIGN_DOWN afterwards:
size = PAGE_ALIGN_DOWN(bank->res->end - start + 1) = 0x10000000
Fix this in three different places.
