Add a new flag, CONFIG_SPL_FRAMEWORK to opt into the common/spl SPL
framework, enable on all of the previously using boards. We move the
spl_ymodem.c portion to common/ and spl_mmc.c to drivers/mmc/. We leave
the NAND one in-place as we plan to replace it later in this series.
We use common/spl to avoid linker problems with respect to merging
constant strings in objects. Otherwise all strings in common/ will be
linked in and kept which grows SPL in size too much.

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.

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.

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.

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.

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.

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.com
Compiling 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.

Several macros are used to identify and locate the microcode binary image
that U-boot needs to upload to the QE or Fman. Both the QE and the Fman
use the QE Firmware binary format to package their respective microcode data,
which is why the same macros are used for both. A given SOC will only have
a QE or an Fman, so this is safe.
Unfortunately, the current macro definition and usage has inconsistencies.
For example, CONFIG_SYS_FMAN_FW_ADDR was used to define the address of Fman
firmware in NOR flash, but CONFIG_SYS_QE_FW_IN_NAND contains the address
of NAND. There's no way to know by looking at a variable how it's supposed
to be used.
In the future, the code which uploads QE firmware and Fman firmware will
be merged.

As a part of the manufacturing process for some of our custom hardware,
we are programming the EEPROMs attached to our Intel 82571EB controllers
from software using U-Boot and Linux.
This code provides several conditionally-compiled features to assist in
our manufacturing process:
CONFIG_CMD_E1000:
This is a basic "e1000" command which allows querying the controller
and (if other config options are set) performing EEPROM programming.
In particular, with CONFIG_E1000_SPI this allows you to display a
hex-dump of the EEPROM, copy to/from main memory, and verify/update
the software checksum.
CONFIG_E1000_SPI_GENERIC:
Build a generic SPI driver providing the standard U-Boot SPI driver
interface. This allows commands such as "sspi" to access the bus
attached to the E1000 controller. Additionally, some E1000 chipsets
can support user data in a reserved space in the E1000 EEPROM which
could be used for U-Boot environment storage.
CONFIG_E1000_SPI:
The core SPI access code used by the above interfaces.
For example, the following commands allow you to program the EEPROM from
a USB device (assumes CONFIG_E1000_SPI and CONFIG_CMD_E1000 are enabled):
usb start
fatload usb 0 $loadaddr 82571EB_No_Mgmt_Discrete-LOM.bin
e1000 0 spi program $loadaddr 0 1024
e1000 0 spi checksum update
Please keep in mind that the Intel-provided .eep files are organized as
16-bit words. When converting them to binary form for programming you
must byteswap each 16-bit word so that it is in little-endian form.
This means that when reading and writing words to the SPI EEPROM, the
bit ordering for each word looks like this on the wire:
Time >>>
------------------------------------------------------------------
... [7, 6, 5, 4, 3, 2, 1, 0, 15, 14, 13, 12, 11, 10, 9, 8], ...
