Currently create_int_queue is only implemented by the ehci code, and that
does not honor interrupt intervals, but other drivers which might also want
to implement create_int_queue may honor intervals, so add an interval param.

Now that "usb start" will only start usb if not already started, we can simply
call "usb start" whenever we (may) need access to usb devices, and it will only
actually scan the bus at the first call.

Currently we've this magic in include/config_distro_bootcmd.h to avoid
scanning the usb bus multiple times.
And it does not work when also using an usb keyboard because then the
preboot command has already scanned the bus, so we're still scanning it
twice.
This commit makes "usb start" only start usb if it is no already started,
allowing us to remove all the magic for it from include/config_distro_bootcmd.h
and just call it unconditionally.
This also causes "usb start" and "usb reset" to actually do what their
different names suggest, rather then both of them doing exactly the same.

Fix use-before-initialized bug in pxa25x_udc driver.
Function usb_gadget_register_driver calls udc_disable,
and udc_disable calls pullup_off that uses dev->mach->udc_command.
But dev->mach is initialized in usb_gadget_register_driver after
calling udc_disable. This patch fixes the order of initialization.

The current sunxi implementation uses gdata, which is going away. It also
sets up DRAM before board_init_f() in SPL.
There is really no reason to do much in s_init() since board_init_f() is
called immediately afterwards. The only change is that we need our own
implementation of board_init_f() which sets up DRAM before the BSS (which
is in DRAM) is cleared.
The s_init() code runs once for SPL and again for U-Boot proper. We
shouldn't need to init the clock/timer/gpio/i2c init twice, so just have it
in SPL.

We need to get rid of this SPL-specific setting of the global_data pointer.
It is already set up in start.S immediately before board_init_f() is called,
and there may be information there that is needed (e.g. pre-reloc malloc
info).

Prior to this change we set the gd pointer early so that we can store
data in it. This becomes problematic for DM changes as well as being
odd in general. Re-work the code paths so that we don't need to set the
gd pointer so early and instead can rely upon the normal setting of it.
In order to do this we do need to move certain calls from s_init into
spl_board_init(), mainly preloader_console_init and
save_omap_boot_params.

"reset.c" and "cpu.c" have no architecture-specific code at all.
Others are applicable to either ARC CPU.
This change is a preparation to submission of ARCv2 architecture port.
Even though ARCv1 and ARCv2 ISAs are not binary compatible most of
built-in modules still have the same programming model - AUX registers
are mapped in the same addresses and hold the same data (new featues
extend existing ones).
So only low-level assembly code (start-up, interrupt handlers) is left
as CPU(actually ISA)-specific. This significantyl simplifies maintenance
of multiple CPUs/ISAs.

Even though existing implementation works fine in preparation to
submission of ARCv2 architecture we need this change.
In case of ARCv2 interrupt vector table consists of just addresses
of corresponding handlers. And if those addresses will be in .text
section then assembler will encode them as everything in .text section
as middle-endian and then on real execution CPU will read swapped
addresses and will jump into the wild.
Once introduced new section is situated so .text section remains the
first which allows us to use common linker option for linking everything
to a specified CONFIG_SYS_TEXT_BASE.

Some cache operations ({i|d}cache_{enable|disable|status} or
flush_dcache_all) are built and used even if CONFIG_SYS_{I|D}CACHE_OFF
is set.
This is required for force disable of caches on early boot.
What if something was executed before U-boot and enabled caches
(low-level bootloaders, previously run kernel etc.)?
But if CPU doesn't really have caches any attempt to access
cache-related AUX registers triggers instruction error exception.
So for convenience we'll try to avoid exceptions by checking if CPU
actually has caches (we check separately data and instruction cache
existence) at all.

If:
1. Toolchains A and B have the same filename
2. Toolchain A is in the PATH
3. Toolchain B is given in ~/.buildman and buildman uses it to build
then buildman will add toolchain B to the end of its path but will not
necessarily use it since U-Boot will find toolchain A first in the PATH.
Try to fix this by putting the toolchain first in the path instead of
last.

Buildman normally obtains the upstream commit by asking git. Provided that
the branch was created with 'git checkout -b <branch> <some_upstream>' then
this normally works.
When there is no upstream, we can try to guess one, by looking up through

a warning if buildman ends up relying on it.
