b44b30260f printk: collect printk stuff into <linux/printk.h> with loglevel support
When we import code from Linux, with regular re-sync planned, we want
to use printk() and pr_*().  U-Boot does not support them in a clean
way.  So, people end up with local macros, or compat headers here and
there, then we occasionally see build errors of definition conflicts.

We have include/linux/compat.h, but putting all sorts of unrelated
things into a single header is just a temporal workaround.  Hence this
patch, to find the best home for all printk variants.  If you want to
use printk() and friends, please include <linux/printk.h>.  This header
is self-contained, and pulls in only a few headers.

When I was testing this clean-up, I noticed the image size exceeded
its platform limit on some boards.  This is because all pr_*() that
were previously defined as no-op in include/linux/mtd/mtd.h (unless
CONFIG_MTD_DEBUG is set), are now enabled.

To make such boards happy, this commit also implements CONFIG_LOGLEVEL.
The concept is similar to the kernel parameter "loglevel".  (Actually,
the Kconfig help message was taken from kernel-paremeter.txt of Linux)
Messages with a loglevel smaller than console loglevel will be printed.

The difference is the loglevel is build-time determined.  To save the
image size, lower priority pr_*() are compiled out.  I set the default
of CONFIG_LOGLEVEL to 6, i.e. pr_notice and higher priority messages
are compiled in.

I adjusted CONFIG_LOGLEVEL to avoid build error for some boards.

77777f769f omap4: Drop redundant CONFIG_OMAP4430 symbol
While there are a few different OMAP4 SoCs, today we always set
CONFIG_OMAP4430 and CONFIG_OMAP44XX.  Convert the few test of
CONFIG_OMAP4430 to CONFIG_OMAP44XX.

6d9481047e drivers: remove writes{b,w,l,q} and reads{b,w,l,q}.
Definition of writes{bwlq}, reads{bwlq} are now added into arch specific
asm/io.h. So removing them from driver to fix re-definition error

2f96b06be5 linux/compat.h: move dev_err, dev_info and dev_dbg from usb driver to compat.h
Since kernel code current use many dev_xxx() instead of using printk. To
compatible, move those dev_xxx from usb driver to linux/compat.h. Then all
driver code can use dev_err, dev_info and dev_vdbg.

This patch also removed duplicated macro definitions in usb driver.

472d546054 Consolidate bool type
'bool' is defined in random places. This patch consolidates them into a
single header file include/linux/types.h, using stdbool.h introduced in C99.

All other #define, typedef and enum are removed. They are all consistent with
true = 1, false = 0.

Replace FALSE, False with false. Replace TRUE, True with true.
Skip *.py, *.php, lib/* files.

833a53c627 musb-new: am35x backend driver
Backend driver for MUSB OTG controllers found on TI AM35x.

It seems that on AM35X interrupt status registers can be updated
_before_ core registers. As we don't use true interrupts in U-Boot
and poll interrupt status registers instead this can result in
interrupt handler being called with non-updated core registers.
This confuses the code and result in hanged transfers.
Add a small delay in am35x_interrupt as a workaround.

eb81955bf0 musb-new: port of Linux musb driver
Existing U-Boot musb driver has no support for the new gadget framework
and also seems to have other limitations. As gadget framework is ported
from Linux it seems pretty natural to port musb gadget driver as well.

This driver supports both host and peripheral modes.

This is not a replacement for current musb driver (at least now) as
there are still some consumers of the old UDC interface.

No DMA operation support included, CONFIG_MUSB_PIO_ONLY should be
defined.

Virtual root hub device is not implemented.

Known problems: with no devices connected usb_lowlevel_start() fails.
