Everytime a dead driver is removed from the list,
we must re-number. This is a painful task.

README: remove wrong config name
There is no CONFIG_PCA953X_INFO symbol.
U-Boot uses CONFIG_CMD_PCA953X_INFO instead, which is described in
"Monitor Functions" section and thus no need to be repeated in the
"GPIO Support" section.
Remove the whole line.

common/cmd_bootm.c: fix subcommand processing in OS specific do_bootm_xxx() functions
In commit "5c427e4: use BOOTM_STATE_OS_CMDLINE flag for plain bootm"
and "3d187b3: Only pass BOOTM_STATE_OS_CMDLINE on PowerPC/MIPS",
BOOTM_STATE_OS_CMDLINE was added to do_bootm for PowerPC and MIPS. This
breaks other OSes (vxworks, netbsd, plan9,...) that don't support
subcommand processing, e.g. they all contain the following code in their
do_bootm_xxx():
if (flag & BOOTM_STATE_OS_PREP)
return 0;
if ((flag != 0) && (flag != BOOTM_STATE_OS_GO))
return 1;
which will result a "subcommand not supported" error.
This patch changes the above logic to:
/* if not go command, pretend everything to be OK */
if (flag != BOOTM_STATE_OS_GO)
return 0;

pxe: fix handling of absolute paths
pxelinux and syslinux differ in their handling of absolute paths in menu
files. A pxelinux path is aways prepended with the bootfile path while
syslinux allows for absolute paths. u-boot was always treating a leading
/ as an absolute path breaking some pxelinux setups. Fix this by adding
a flag to distinguish pxelinux vs. syslinux behavior.

Introduce common timer functions
Many platforms duplicate pretty much the same timer code yet they all have
a 32-bit freerunning counter register. Create a common implementation that
minimally requires 2 or 3 defines to add timer support:
CONFIG_SYS_TIMER_RATE - Clock rate of the timer counter
CONFIG_SYS_TIMER_COUNTER - Address of 32-bit counter
CONFIG_SYS_TIMER_COUNTS_DOWN - Define if counter counts down
All functions are weak or ifdef'ed so they can still be overriden by any

The link rule `$(call cmd_link_o_target, $(OBJS) $(obj)kgdb.o)'

kbdg.o is not included in $(OBJS) but linked into $(LIB)
and $(LIB) is not dependent on kgdb.o.
(Broken dependency tracking)

Makefile: prepare for using Kbuild-style Makefile
Every makefile in sub directories has common lines
at the top and the bottom.
This commit pushes the common parts into script/Makefile.build.
Going forward sub-makefiles only need to describe this part:
COBJS := ...
COBJS += ...
SOBJS := ...
But using obj-y is preferable to prepare for switching to Kbuild.
The conventional (non-Kbuild) Makefile style is still supported.
This is achieved by greping the Makefile before entering into it.
U-Boot conventional sub makefiles always include some other makefiles.
So the build system searches a line beginning with "include" keyword
in the makefile in order to distinguish which style it is.
If the Makefile include a "include" line, we assume it is a conventional
U-Boot style. Otherwise, it is treated as a Kbuild-style makefile.
With this tweak, we can switch sub-makefiles
from U-Boot style to Kbuild style little by little.
obj-y := foo/
syntax (descending into the sub directory) is not supportd yet.
It will be implemented in the upcomming commit.

mmc: sdhci: Avoid commands errors by simple timeout adaptation.
Old command timeout value was too small and it caused I/O errors which
led to uncompleted read/write/erase operations and filesystem errors.
Timeout adaptation fixes this issue.
Changes in sdhci_send_command() function:
- change timeout variable to static
- increase default command timeout to 100 ms
- add definition of max command timeout value,
which can be redefined in each board config file
- wait for card ready state for max defined time
if it doesn't exceed defined maximum or return COMM_ERR
Once successfully increased timeout value will be used in next function
call. This fix was tested on Goni, Trats, Trats2 boards by testing UMS
on MMC storage.
Changes v2:
- move global variable cmd_timeout into function sdhci_send_command()
- change condition "==" to ">=" when comparing time with timeout
- print information about timeout increasing and card busy timeout
