Rework the emulation of serial console via JTAG from simple ad-hoc
implementation of serial port routines to CONFIG_SERIAL_MULTI and
enable CONFIG_SERIAL_MULTI unconditionally for blackfin.
In order for the JTAG serial console to take precedence over all
other serial ports available in system, implement override for
default_serial_console call returning this JTAG serial console.
This brings in a bit of a growth of size, but eventually will allow

This macro simplifies declaration of weak aliases for per-driver
functions, which register these drivers with the serial subsystem.
The idea here is to push serial_register() calls from serial.c into
the drivers. To avoid pile of ifdef construct as it is now, create
weak aliases to these functions, which in case the driver is not
present alias onto an empty function, which is in turn optimized out
altogether.

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

If 'fdt_addr' is set and 'fdt blob' is not retrieved from the tftp pass

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

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.

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.
