__i2c_read always ends with a STOP condition thereby releasing

Since commit 5c2ff323a9 ("mpc8360emds:

Though, it appears that QE Ethernet in Gigabit mode can't transmit
large packets when it tries to work with a data in LBC SDRAM (memtest
didn't discover any issues, is LBC SDRAM just too slow?).
With this patch we can still use the board without DDR memory, but
if DDR is available, we don't use LBC SDRAM.

Commit 4abd844d8e extended the fdt command parser to handle property
strings which are split across multiple arguments but it was broken for
byte streams and strings.
Byte stream parsing:
* Fixes where it would terminate early or go into an endless loop.
* Fixes a 0x00 being inserted into the data if there is a space after
'[' or a separate argument.
* Fixes dereferencing the argument pointer after the last argument.
* Checks for bad characters.
String parsing:
* Treat multiple arguments as a string list. This fixes an issue where
only the last argument was stored.

U-Boot can detect if an IDE device is present or not.
If not, and this new config option is activated, U-Boot
removes the ATA node from the DTS before booting Linux,
so the Linux IDE driver does not probe the device and
crash. This is needed for buggy hardware (uc101) where
no pull down resistor is connected to the signal IDE5V_DD7.

The means to determine the core, bus, and DDR frequencies are completely

On CoreNet style platforms the timebase frequency is the bus frequency

The p4080 SoC has a significant amount of commonality with the 85xx/PQ3
platform. We reuse the 85xx immap and just add new definitions for
local access and global utils. The global utils is now broken into
global utils, clocking and run control/power management.
The offsets from CCSR for a number of blocks have also changed. We
introduce the CONFIG_FSL_CORENET define to distinquish the PQ3 style of
platform from the new p4080 platform. We don't use QoirQ as there are

The PCI/PCI-e support for the sbc8548 was based on an earlier
version of what the MPC8548CDS board was using, and in its
current state it won't even compile. This re-syncs it to match
the latest codebase and makes use of the new shared PCI functions
to reduce board duplication.
It borrows from the MPC8568MDS, in that it pulls the PCI-e I/O
back to 0xe280_0000 (where PCI2 would be on MPC8548CDS), and
similarly it coalesces the PCI and PCI-e mem into one single TLB.
Both PCI-x and PCI-e have been tested with intel e1000 cards
under linux (with an accompanying dts change in place)

The sbc8548 has a 64MB SODIMM flash module off of CS6 that
previously wasn't enumerated by u-boot. There were already
BR6/OR6 settings for it [used by cpu_init_f()] but there
was no TLB entry and it wasn't in the list of flash banks
reported to u-boot.
The location of the 64MB flash is "pulled back" 8MB from
a 64MB boundary, in order to allow address space for the
8MB boot flash that is at the end of 32 bit address space.
This means creating two 4MB TLB entries for the 8MB chunk,
and then expanding the original boot flash entry to 64MB
in order to cover the 8MB boot flash and the remainder
(56MB) of the user flash.

There are a couple defines and PCI bridge quirks related to the PCI
backplane of the MPC8548CDS that have no meaning in the context of
the port to the sbc8548 board, so delete them.
Also, the form factor of the sbc8548 is a standalone board with a
single PCI-X and a single PCI-e slot. That pretty much guarantees
that it will never be a PCI agent itself, so the host/agent and root
complex/end node distinctions have been removed.
Similarly, since there is no physical connector mapping to PCI2, so
all references of PCI2 in the board support files have been removed
as well.
