Some systems (like Google Link device) provide the ability to keep a
history of the target CPU port80 accesses, which is extremely handy
for debugging. The problem is that the EC handling port 80 access is
orders of magnitude slower than the AP. This causes random loss of
trace data.
This change allows to throttle port 80 accesses such that in case the
AP is trying to post faster than the EC can handle, a delay is
introduced to make sure that the post rate is throttled. Experiments
have shown that on Link the delay should be at least 350,000 of tsc
clocks.
Throttling is not being enabled by default: to enable it one would
have to set MIN_PORT80_KCLOCKS_DELAY to something like 400 and rebuild
the u-boot image. With upcoming EC code optimizations this number
could be decreased (new new value should be established
experimentally).

Some u-boot modules rely on availability of get_ticks() and
get_tbclk() functions, reporting a free running clock and its
frequency respectively. Traditionally these functions return number
and frequency of timer interrupts.
Intel's core architecture processors however are known to run the
rdtsc instruction at a constant rate of the so called 'Max Non Turbo
ratio' times the external clock frequency which is 100MHz. This is
just as good for the timer tick functions in question.

This changes the layout in decreasing addresses from:

to
1. Sections in the image
2. Heap
3. Stack
This allows the stack to grow significantly more since it isn't constrained by
the other u-boot areas. More importantly, the generic memory wipe code assumes
that the stack is the lowest addressed area used by the main part of u-boot.
In the original layout, that means that u-boot tramples all over itself. In
the new layout, it works.

Implement arch_phys_memset so that it can set memory at physical addresses
above 4GB using PAE paging. Because there are only 5 page tables in PAE mode,
1 PDPT and 4 PDTs, those tables are statically allocated in the BSS. The
tables must be 4K page aligned and are declared that way, and because U-Boot
starts as 4K aligned and the relocation code relocates it to a 4K aligned
address, the tables work as intended.
While paging is turned on, all 4GB are identity mapped except for one 2MB
page which is used as the window into high memory. This way, U-Boot will
continue to work as expected when running code that expects to access memory
freely, but the code can still get at high memory through its window.
The window is put at 2MB so that it's 2MB page aligned, low in memory to be
out of the way of things U-Boot is likely to care about, and above the lowest
1MB where lots of random things live.

A hook is installed to configure PCI bus bridges as they encountered by u-boot.
The hook extracts the secondary bus number from the bridge's config space and
then recursively scans that bus.
On Coreboot, the PCI bus address space has identity mapping with the
physical address space, so declare it as such to ensure that the "pci_map_bar"
function used by some PCI drivers is behaving properly. This fixes the
EHCI PCI driver initialization on Stumpy.
This was tested as follows:
Ran the PCI command on Alex, saw devices on bus 0, the OXPCIe 952 on
bus 1, and empty busses 2 through 5. This matches the bridges
reported on bus 0 and the PCI configuration output from coreboot.

U-boot needs a host controller or "hose" to interact with the PCI busses
behind them. This change installs a host controller during initialization of
the coreboot "board" which implements some of X86's basic PCI semantics. This
relies on some existing generic code, but also duplicates a little bit of code
from the sc520 implementation. Ideally we'd eliminate that duplication at some
point.
It looks like in order to scan buses beyond bus 0, we'll need to tell u-boot's
generic PCI configuration code what to do if it encounters a bridge,
specifically to scan the bus on the other side of it.

with NAND SPL because the main U-Boot starts at an offset into the image
in order to skip the SPL itself.
Fix the TLB entry to always start at a proper alignment. We still assume that
CONFIG_SYS_MONITOR_BASE doesn't start immediately before a large-page boundary
thus requiring multiple TLB entries.

This was introduced by commit 2446151974, but it
fails in a minimal SPL build where the only thing in arch/powerpc/lib is
cache.c, which apparently doesn't generate any fixup records.
The problem is reported to occur with GCC 3.x, so insist on GCC 4.0 or newer.

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.

Linux usb/ch9.h seems to have all the same information (and more)
as usbdescriptors.h so use the former instead of the later one.
As a consequense of this change USB_SPEED_* values don't correspond
directly to EHCI speed encoding anymore, I've added necessary
recoding in EHCI driver. Also there is no point to put speed into
pipe anymore so it's removed and a bunch of host drivers fixed to
look at usb_device->speed instead.
Old usbdescriptors.h included is not removed as it seems to be
used by old USB device code.
This makes usb.h and usbdevice.h incompatible. Fortunately the
only place that tries to include both are the old MUSB code and
it needs usb.h only for USB_DMA_MINALIGN used in aligned attribute
on musb_regs structure but this attribute seems to be unneeded
(old MUSB code doesn't support any DMA at all).

Change tegra SPL to use common SPL framework. Any tegra specific
initialization is now done in spl_board_init() instead of
board_init_f()/board_init_r(). Only one SPL boot target is supported
on tegra, which is boot to RAM image. jump_to_image_no_args() must be
overridden on tegra so the host CPU can be initialized.

Add an ASSERT() to u-boot.lds to detect an SPL that doesn't fit within
SPL_TEXT_BASE..SPL_MAX_SIZE.
Different .lds files implement this check in two possible ways:
1) An ASSERT() like this
2) Defining a MEMORY region of size SPL_MAX_SIZE, and re-directing all
linker output into that region. Since u-boot.lds is used for both
SPL and main U-Boot, this would entail only sometimes defining a
MEMORY region, and only sometimes performing that redirection, and
hence option (1) was deemed much simpler, and hence implemented.
Note that this causes build failures at least for NVIDIA Tegra Seaboard
and Ventana. However, these are legitimate; the SPL doesn't fit within
the required space, and this does cause runtime issues.

When -ffunction-sections or -fdata-section are used, symbols are placed
into sections such as .data.eserial1_device and .bss.serial_current.
Update the linker script to explicitly include these. Without this
change (at least with my gcc-4.5.3 built using crosstool-ng), I see that
the sections do end up being included, but __bss_end__ gets set to the
same value as __bss_start.

The woodburn board is based on the MX35 SOC.
Support for both external (NOR) and internal
(SD Card) boot mode are added. It uses the
generic SPL framework to implement the internal boot
mode.
The following peripherals are supported:
- Ethernet (FEC)
- SD Card
- NAND (512 MB)
- NOR Flash
In the internal boot mode, a simple imximage header
is generated to set the address in internal RAM
where the SOC must copy the SPL code. The initial setup
is then demanded to the SPL itself.

In order to support low power state, you must source kernel system
timers to persistent clock, available across suspend/resume. In case of
AM335x device, the only source we have is, RTC32K, available in
wakeup/always-on domain. Having said that, during validation it has
been observed that, RTC clock need couple of seconds delay to stabilize
the RTC OSC clock; and such a huge delay is not acceptable in kernel
especially during early init and also it will impact quick/fast boot
use-cases.
So, RTC32k OSC enable dependency has been shifted to
SPL/first-bootloader.

Currently, the SRIO and PCIE boot master module will be compiled into the
u-boot image if the macro "CONFIG_FSL_CORENET" has been defined. And this
macro has been included by all the corenet architecture platform boards.
But in fact, it's uncertain whether all corenet platform boards support
this feature.
So it may be better to get rid of the macro "CONFIG_FSL_CORENET", and add
a special macro for every board which can support the feature. This
special macro will be defined in the header file
"arch/powerpc/include/asm/config_mpc85xx.h". It will decide if the SRIO
and PCIE boot master module should be compiled into the board u-boot image.
