dm: define dev_*() log functions in DM header

2017-10-04T16:00:20+00:00

Many drivers had started to use dev_err, dev_info, etc. for log
functions.  Currently, we are relying on , but I
guess the best home is , taking into account that
Linux defines them in .

For now, I am leaving the ones in  because lots of
Linux-originated code uses dev_*(), but the first argument is not
struct udevice, so we need to ignore the bogus argument.  More
efforts are needed to iron out the issues.

bug.h: sync BUILD_BUG stuff with Linux 4.13

2017-10-04T16:00:19+00:00

As commit 84b8bf6d5d2a ("bug.h: move BUILD_BUG_* defines to
include/linux/bug.h") noted, include/linux/bug.h was locally
modified for U-Boot because the name conflict of error() caused
build errors at that time.

Now error() is gone, so we can fully sync BUILD_BUG* with Linux.
These macros are just compile-time utilities.  Nothing depends on
platform code, so it should make sense to simply copy Linux's ones.

Please note Linux split BUILD_BUG stuff out into 
by commit bc6245e5efd7.  Let's follow it.

printk: collect printk stuff into with loglevel support

2017-10-04T14:31:17+00:00

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 .  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.

usb: xhci: Honor endpoint's interval

2017-10-01T14:32:54+00:00

USB endpoint reports the period between consecutive requests to send
or receive data as bInverval in its endpoint descriptor. So far this
is ignored by xHCI driver and the 'Interval' field in xHC's endpoint
context is always programmed to zero which means 1ms for low speed
or full speed , or 125us for high speed or super speed. We should
honor the interval by getting it from endpoint descriptor.

linux/io.h: import generic ioread* / iowrite* accessors from Linux

2017-09-12T22:02:23+00:00

Some drivers in Linux (ex. drivers/mtd/nand/denali.c) use
ioread*/iowrite* accessors.  Import them to make drivers more
synced.  I copied code from include/asm-generic/io.h of Linux.
