The Vitesse VSC7385 is a 5-port switch found on the Freescale MPC8349E-mITX
and other boards. A small firwmare must be uploaded to its on-board memory
before it can be enabled. This patch adds the code which uploads firmware
(but not the firmware itself).
Previously, this feature was provided by a U-Boot application that was
made available only on Freescale BSPs. The VSC7385 firmware must still
be obtained separately, but at least there is no longer a need for a separate
application.

These defines embedded the u-boot env variables and/or the bd_t structure
in the fdt blob. The conclusion of discussion on the u-boot email list
was that embedding these in the fdt blob is not useful: there are better
ways of passing the data (in fact, the fdt blob itself replaces the
bd_t struct).
The only board that enables these is the stxxtc and they don't appear

Introducing routines for parsing new uImage format bootm arguments:

[<addr>]:<subimg> - subimage specification
New format images can contain multiple subimages of the same type. For example
a single new format image file can contain three kernels, two ramdisks and a
couple of FDT blobs. Subimage and configuration specifications are extensions
to bootm (and other image-related commands) arguments' syntax that allow to
specify which particular subimage should be operated on.
Subimage specification is used to denote a particular subimage. Configurations
are a bit more complex -- they are used to define a particualr booting setup,
for example a (kernel, fdt blob) pair, or a (kernel, ramdisk, fdt blob) tuple,

This patch adds support for the SPI controller found on Freescale PowerPC
processors such as the MCP834x family. Additionally, a new config option,
CONFIG_HARD_SPI, is added for general purpose SPI controller use.

The commit 9e89647889
will cause the mpc8315erdb board can't boot up.
The patch fix that bug, and remove the duplicated #ifdef
CFG_SPCR_TSECEP code and clean the SCCR_TSEC2 for
MPC8313E processor.

Add a set of functions to manipulate TLB entries:
* set_tlb() - write a tlb entry
* invalidate_tlb() - invalidate a tlb array
* disable_tlb() - disable a variable size tlb entry
* init_tlbs() - setup initial tlbs based on static table

Move the initialization of the LAWs into C code and provide an API
to allow modification of LAWs after init.
Board code is responsible to provide a law_table and num_law_entries.
We should be able to use the same code on 86xx as well.

With serial, NE2000, IDE support. Tested in big-endian mode.
Memory size hard-coded to 128M for now, so don't play with
the -m option.

Convert the board/freescale/common/Makefile to use
CONFIG_* options to select which files to conditionally
compile into the board/freescale/common library rather
than conditionally compiling entire files.
Now handles::
CONFIG_FSL_PIXIS
CONFIG_FSL_DIU_FB
CONFIG_PQ_MDS_PIB
CONFIG_ID_EEPROM is introduced until CFG_ID_EEPROM is gone.

These changes were identified by HighSmith Bill ,Mazzyar and Joseph for
DDR configuration in u-boot code. Some are related to performance, some
affect stability and some correct few basic errors in the current
configuration.
The changes have been tested and found to give better memory latency
figures on MPC8313eRDB.LMBench figures prove it.
The changes are:
- CS0_CONFIG[ AP_n_EN] is changed from 1 to 0
(this may improve performance for application with many read
or write to open pages).
- CS0_CONFIG[ODT_WR_CFG] is currently changed from 100 to
001 (activating all the CS when only one is used may cause
unwanted noise on the system)
- TIMING_CFG_1[ACTTOPRE] is changed from 9clks to 8clks (based on
Tras=45ns)
- TIMING_CFG_1[REFREC] changed from 21 clks to 18clks.
- TIMING_CFG_2[AL] value changed from 0 setting to 1 clk to
comply with the 3 ODT clk requirements)
- TIMING_CFG_2[CPO] was set to a reserved value, changed to RL+3/4.
- TIMING_CFG_2[FOUR_ACT] is changed from 10 clks to 6clks.
- DDR_SDRAM_MODE[AL]changed from 0 to 1.
- DDR_SDRAM_MODE[WRREC] changed from 1 clk to 3 clks.
- DDR_SDRAM_INTERVAL[REFINT] is changed from 0x0320 to 0x0510.
- DDR_SDRAM_INTERVAL[BSTOPRE] is changed from 0x64 to 0x0500.
The patch is based of git://www.denx.de/git/u-boot-mpc83xx.git
