Introduce CONFIG_PCI_ENUM_ONLY variable for platforms that just want a
quick enumberation of the PCI devices, but don't need any setup work done.
This is very beneficial on platforms that have u-boot loaded by another
boot loader which does a more sophisticated job of setup of PCI devices
than u-boot. That way, u-boot can just read what's there and get on
with life. This is what SeaBIOS does.Signed-off-by: Andrew Sharp

Erratum A004510 says that under certain load conditions, modified
cache lines can be discarded, causing data corruption.To work around this, several CCSR and DCSR register updates need to be
made in a careful manner, so that there is no other transaction in
corenet when the update is made.The update is made from a locked cacheline, with a delay before to flush
any previous activity, and a delay after to flush the CCSR/DCSR update.
We can't use a readback because that would be another corenet
transaction, which is not allowed.We lock the subsequent cacheline to prevent it from being fetched while
we're executing the previous cacheline. It is filled with nops so that a
branch doesn't cause us to fetch another cacheline.Ordinarily we are running in a cache-inhibited mapping at this point, so
we temporarily change that. We make it guarded so that we should never
see a speculative load, and we never do an explicit load. Thus, only the
I-cache should ever fill from this mapping, and we flush/unlock it
afterward. Thus we should avoid problems from any potential cache
aliasing between inhibited and non-inhibited mappings.NOTE that if PAMU is used with this patch, it will need to use a
dedicated LAW as described in the erratum. This is the responsibility
of the OS that sets up PAMU.Signed-off-by: Scott Wood

When boot from SRIO, slave's ENV can be stored in master's memory space,
then slave can fetch the ENV through SRIO interface.NOTE: Because the slave can not erase, write master's NOR flash by SRIO
interface, so it can not modify the ENV parameters stored in
master's NOR flash using "saveenv" or other commands.Master needs to:
1. Put the slave's ENV into it's own memory space.
2. Set an inbound SRIO window covered slave's ENV stored in master's
memory space.
Slave needs to:
1. Set a specific TLB entry in order to fetch ucode and ENV from master.
2. Set a LAW entry with the TargetID SRIO1 or SRIO2 for ucode and ENV.Signed-off-by: Liu Gang

For the powerpc processors with SRIO interface, boot location can be configured
from SRIO1 or SRIO2 by RCW. The processor booting from SRIO can do without flash
for u-boot image. The image can be fetched from another processor's memory
space by SRIO link connected between them.The processor boots from SRIO is slave, the processor boots from normal flash
memory space and can help slave to boot from its memory space is master.
They are different environments and requirements:master:
1. NOR flash for its own u-boot image, ucode and ENV space.
2. Slave's u-boot image in master NOR flash.
3. Normally boot from local NOR flash.
4. Configure SRIO switch system if needed.
slave:
1. Just has EEPROM for RCW. No flash for u-boot image, ucode and ENV.
2. Boot location should be set to SRIO1 or SRIO2 by RCW.
3. RCW should configure the SerDes, SRIO interfaces correctly.
4. Slave must be powered on after master's boot.
5. Must define CONFIG_SYS_QE_FMAN_FW_IN_REMOTE because of no ucode
locally.For the slave module, need to finish these processes:
1. Set the boot location to SRIO1 or SRIO2 by RCW.
2. Set a specific TLB entry for the boot process.
3. Set a LAW entry with the TargetID SRIO1 or SRIO2 for the boot.
4. Slave's u-boot image should be generated specifically by
make xxxx_SRIOBOOT_SLAVE_config.
This will set SYS_TEXT_BASE=0xFFF80000 and other configurations.Signed-off-by: Liu Gang

This patch adds the support for high speed in usb device framework and usbtty
driver. This feature has been kept within a macro CONFIG_USBD_HS, so the board
configuration files have to define this macro to enable high speed support.Along with that specific peripheral drivers also need to define a function to
let the framework know that the enumeration has happened at high speed.
This function prototype is "int is_usbd_high_speed(void)"Signed-off-by: Vipin Kumar

is impossible and we don't need to worry about trampling on UARTs, etc.Signed-off-by: Simon Glass

This defines the basics of a new boot time measurement feature. This allows
logging of very accurate time measurements as the boot proceeds, by using
an available microsecond counter.To enable the feature, define CONFIG_BOOTSTAGE in your board config file.
Also available is CONFIG_BOOTSTAGE_REPORT which will cause a report to be
printed just before handing off to the OS.Most IDs are not named at this stage. For that I would first like to
renumber them all.Timer summary in microseconds:

The commit message of a28afca (Add uboot "fdt_high" enviroment variable)
states that fdt_high behaves similarly to the existing initrd_high.
But fdt_high actually has an outstanding difference from initrd_high.
The former specifies the start address, while the later specifies the
end address.As fdt_high and initrd_high will likely be used together, it'd be nice
to have them behave same. The patch changes the behavior of fdt_high
to have it aligned with initrd_high.The document of fdt_high in README is updated with an example to
demonstrate the usage of this environment variable.Signed-off-by: Shawn Guo

From: Sonny Rao
These functions are useful in U-Boot because they allow a graceful failure
rather than an unpredictable stack overflow when printf() buffers are
exceeded.Mostly copied from the Linux kernel. I copied vscnprintf and
scnprintf so we can change printf and vprintf to use the safe
implementation but still return the correct values.(Simon Glass modified this commit a little)

This patch adds support for console output before the console is inited.
The main purpose of this is to deal with a very early panic() which would
otherwise cause a silent hang.A new board_pre_console_putc() function is added to the board API. If
provided by the board it will be called in the event of console output
before the console is ready. This function should turn on all UARTs and
spray the character out if it possibly can.The feature is controlled by a new CONFIG_PRE_CONSOLE_PUTC option.

TPM (Trusted Platform Module) is an integrated circuit and
software platform that provides computer manufacturers with the
core components of a subsystem used to assure authenticity,
integrity and confidentiality.This driver supports version 1.2 of the TCG (Trusted Computing
Group) specifications.The TCG specification defines several so called localities in a
TPM chip, to be controlled by different software layers. When
used on a typical x86 platform during the firmware phase, only
locality 0 can be accessed by the CPU, so this driver even while
supporting the locality concept presumes that only locality zero
is used.This implementation is loosely based on the article "Writing a
TPM Device Driver" published on http://ptgmedia.pearsoncmg.comCompiling this driver with DEBUG defined will generate trace of
all accesses to TMP registers.This driver has been tested and is being used in three different
functional ChromeOS machines (Pinetrail and Sandy Bridge Intel
chipsets) all using the same Infineon SLB 9635 TT 1.2 device.A u-boot cli command allowing access to the TPM was also
implemented and is being submitted as a second patch.Change-Id: I22a33c3e5b2e20eec9557a7621bd463b30389d73
