This patch adds support for networking in SPL. Some devices are
capable of loading SPL via network so it makes sense to load the
main U-Boot binary via network too. This patch tries to use
existing network code as much as possible. Unfortunately, it depends
on environment which in turn depends on other code so SPL size
is increased significantly. No effort was done to decouple network
code and environment so far.

We need to initialize timer properly, otherwise all delays

Now DT support is becoming common for all new SoC's. Hence it is better
to have option for getting specific FDT from the remote server.
This patch adds support for new label i.e. 'fdt'. This will allow to
retrieve 'fdt blob' from the remote server. This patch take care for
the following scenarios.
The usage of fdt is optional.
The 'fdt blob' can be retrieved from tftp or can be available locally
or can be absent.
If 'fdt_addr_r' environment variable is set and 'fdt' label is defined
retrieve 'fdt blob' from tftp. 'fdt_addr_r' is then passed along bootm
command.
If 'fdt_addr' is set and 'fdt blob' is not retrieved from the tftp pass
'fdt_addr' to bootm command. In this case 'fdt blob' will be available
at 'fdt_addr'.
If 'fdt_addr' is not set and 'fdt blob' is not retrieve from tftp pass
NULL to boot command. In this case 'fdt blob' is not required and absent.

Previously u-boot would initialize the network interface for every
network operation and then shut it down again. This makes sense for
most operations where the network in not known to be needed soon after
the operation is complete. In the case of netconsole, it will use the
network for every interaction with the shell or every printf. This
means that the network is being reinitialized very often. On many
devices, this intialization is very slow.
This patch checks for consecutive netconsole actions and leaves the
ethernet hardware initialized between them. It will still behave the
same old way for all other network operations and any time another
network operation happens between netconsole operations.

First, remove the puts from the case where we don't have an mkimage
header as this is somewhat common and intentional for no-arg target
images. Second, rework the final switch statement in board_init_r to,
in the case of !CONFIG_SPL_OS_BOOT be only about doing debug prints
about if we know what the magic is or not (the CONFIG_SPL_OS_BOOT case
is unchanged). Then we call jump_to_image_no_args(). This gives us the
same behavior as before but with slightly smaller code.

On some system (e.g. powerpc), the load-address and entry-point is
located at address 0. So the current approach to load the image
(payload) including the header to the address "load-address - 64"
can't work here.
This patch adds an flag to skip this copying including header to
the SPL framework. By setting SPL_COPY_PAYLOAD_ONLY, only the
playload will be copied. This will be used by the SPL NOR flash
driver on powerpc.

SPL NOR flash booting support is quite simple. Only copying of the
images is needed.
On MPC5xxx we need to make sure to only use the standard memcpy()
implementation and not the MPC5xxx specific one. As the MPC5xxx
version has some complexity which is not needed for this SPL
booting.

In SPL (CONFIG_SPL_FRAMEWORK) board_init_f must setup the stack pointer,
clear the BSS and call board_init_r. We mark this as weak as some
platforms may need to perform additional initalization at this point.
We provide a gd that we know will be in a usable location, once the BSS
has been cleared to help with this as well. Finally, we no longer call
relocate_code so remove that from the armv7 version.
Next, both board_init_f and jump_to_image_linux are going to be
inherently arch-specific, so move these versions to arch/arm/lib/spl.c

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.

When storage devices contain files larger than the embedded RAM, it is
useful to be able to read these files by chunks, e.g. for a software
update to the embedded NAND Flash from an external storage device (USB
stick, SD card, etc.).
Hence, this patch makes it possible by adding a new FAT API to read
files from a given position. This patch also adds this feature to the
fatload command.

If the bmp pointer is null then U-Boot will get stuck when trying
to load the image.
What's worse, it will get stuck before the U-Boot shell becomes
available to the user, thus making it difficult to correct the
situation.

This implements the following:
part uuid mmc 0:1
-> print partition UUID
part uuid mmc 0:1 uuid
-> set environment variable to partition UUID
part list mmc 0
-> list the partitions on the specified device
"part uuid" can be useful when writing a bootcmd which searches all
known devices for something bootable, and then wants the kernel to
use the same partition as the root device, e.g.:
part uuid ${devtype} ${devnum}:${rootpart} uuid
setenv bootargs root=PARTUUID=${uuid} ...

Rework get_device_and_partition() to:
a) Implement a new partition ID of "auto", which requests that U-Boot
search for the first "bootable" partition, and fall back to the first
valid partition if none is found. This way, users don't need to
specify an explicit partition in their commands.
b) Make use of get_device().
c) Add parameter to indicate whether returning a whole device is
acceptable, or whether a partition is mandatory.
d) Make error-checking of the user's device-/partition-specification
more complete. In particular, if strtoul() doesn't convert all
characters, it's an error rather than just ignored.
The resultant device/partition returned by the function will be as
follows, based on whether the disk has a partition table (ptable) or not,
and whether the calling command allows the whole device to be returned
or not.
(D and P are integers, P >= 1)
D
D:
No ptable:
!allow_whole_dev: error
allow_whole_dev: device D
ptable:
device D partition 1
D:0
!allow_whole_dev: error
allow_whole_dev: device D
D:P
No ptable: error
ptable: device D partition P
D:auto
No ptable:
!allow_whole_dev: error
allow_whole_dev: device D
ptable:
first partition in device D with bootable flag set.
If none, first valid paratition in device D.
Note: In order to review this patch, it's probably easiest to simply
look at the file contents post-application, rather than reading the
patch itself.

When boot from PCIE, slave's core should be in holdoff after powered on for
some specific requirements. Master will release the slave's core at the
right time by PCIE interface.
Slave's ucode and ENV can be stored in master's memory space, then slave
can fetch them through PCIE interface. For the corenet platform, ucode is
for Fman.
NOTE: Because the slave can not erase, write master's NOR flash by
PCIE interface, so it can not modify the ENV parameters stored
in master's NOR flash using "saveenv" or other commands.
environment and requirement:
master:
1. NOR flash for its own u-boot image, ucode and ENV space.
2. Slave's u-boot image is in master NOR flash.
3. Put the slave's ucode and ENV into it's own memory space.
4. Normally boot from local NOR flash.
5. Configure PCIE 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 one PCIE interface by RCW.
3. RCW should configure the SerDes, PCIE interfaces correctly.
4. Must set all the cores in holdoff by RCW.
5. Must be powered on before master's boot.
For the slave module, need to finish these processes:
1. Set the boot location to one PCIE interface by RCW.
2. Set a specific TLB entry for the boot process.
3. Set a LAW entry with the TargetID of one PCIE for the boot.
4. Set a specific TLB entry in order to fetch ucode and ENV from
master.
5. Set a LAW entry with the TargetID one of the PCIE ports for
ucode and ENV.
6. Slave's u-boot image should be generated specifically by
make xxxx_SRIO_PCIE_BOOT_config.
This will set SYS_TEXT_BASE=0xFFF80000 and other configurations.
In addition, the processes are very similar between boot from SRIO and
boot from PCIE. Some configurations like the address spaces can be set to
the same. So the module of boot from PCIE was added based on the existing
module of boot from SRIO, and the following changes were needed:
1. Updated the README.srio-boot-corenet to add descriptions about
boot from PCIE, and change the name to
README.srio-pcie-boot-corenet.
2. Changed the compile config "xxxx_SRIOBOOT_SLAVE" to
"xxxx_SRIO_PCIE_BOOT", and the image builded with
"xxxx_SRIO_PCIE_BOOT" can support both the boot from SRIO and
from PCIE.
3. Updated other macros and documents if needed to add information
about boot from PCIE.

eMMC devices may have hardware-level partitions: 2 boot partitions,
up to 4 general partitions, plus the user area. This change introduces
optional config variable CONFIG_SYS_MMC_ENV_PART to indicate which
partition the environment should be stored in: 0=user, 1=boot0, 2=boot1,
4..7=general0..3. This allows the environment to be kept out of the user
area, which simplifies the management of OS-/user-level (MBR/GPT)
partitions within the user area.
